confidence

Dow Crag is currently wet and will remain so — today has seen light rain building to heavier showers this afternoon, with 100% cloud cover likely keeping the crag in mist. The forecast shows a prolonged spell of heavy rain over the next five days (nearly 80mm predicted), making conditions unsuitable for climbing.

Based on weather conditions only — does not cover bird nesting restrictions or other access issues.

Crag Considerations
  • Extensive seepage lines on Dow's buttresses become active after prolonged wet spells — the 52mm that fell from Aug 16–20 followed by today's rain will have reactivated these, and they will persist well into any subsequent dry spell.
  • At 600m with 100% cloud cover and humidity above 90%, the crag is very likely sitting in cloud today, meaning surfaces will be wet from mist contact regardless of direct rainfall.
  • The east/NE aspect means afternoon shade is the norm, and with the current easterly wind the crag face is directly exposed to incoming moisture-laden air, preventing any useful drying.
  • The 60+ minute approach via Walna Scar road is itself exposed and unpleasant in prolonged rain; retreat in deteriorating conditions is committing.
Warnings 3
  • Multi-pitch routes on wet volcanic rock at 600m are extremely dangerous — friction loss on this rock type when wet is severe and falls on trad gear at this venue can be very serious.
  • The crag is likely in cloud with poor visibility; route-finding on Dow's complex buttress structure is difficult in mist.
  • Streams and becks on the approach will be swollen after the recent and ongoing rain — take care on the Walna Scar approach.
Reasoning
Moisture State

The rock is wet — 6.3mm falling today on top of a recent heavy spell (52mm from Aug 16–20), with humidity at 90%+ and the crag almost certainly in cloud.

Drying Analysis

A brief dry window Aug 21–25 allowed some surface drying, but the E/NE aspect and high altitude limited this, and today's renewed rain has reset any progress.

Structural Risk

Non-porous BVS volcanic rock is not at risk of structural damage, but the primary hazard is severely reduced friction on wet surfaces during multi-pitch trad routes.

Seasonal Factors

Late August in the Lakes is entering the wetter autumn transition; the incoming frontal system delivering nearly 80mm over five days is typical of this seasonal shift.

Contributing Factors 6
Active rain today
95%

6.3mm total today with showers intensifying through the afternoon (2.7mm at 15:00 alone), ensuring the rock is thoroughly wet.

Crag likely in cloud
90%

100% cloud cover all day at valley level combined with 90–97% humidity means the crag at 600m is almost certainly shrouded in mist, depositing moisture on all surfaces.

Heavy rain forecast ahead
85%

Nearly 80mm of rain is forecast over the next five days, with 32mm on Aug 28 alone — conditions will deteriorate further before any improvement.

Recent prolonged wet spell
85%

Over 50mm fell between Aug 16–20, recharging seepage lines across the buttresses; the brief dry window of Aug 21–25 was insufficient to fully drain these at altitude.

Easterly wind on E/NE face
80%

The current easterly wind drives moisture directly onto the climbing face rather than aiding drying, compounding the wet conditions.

Non-porous rock type
95%

BVS volcanic rock won't suffer structural damage from the moisture, but friction is drastically reduced when wet, making multi-pitch trad climbing dangerous.

Recommendations 3
  • Do not attempt Dow Crag today or in the coming days — the prolonged wet forecast makes conditions unsuitable for safe climbing.
  • Monitor conditions from around Sep 2 onward if the forecast dry day on Sep 1 materialises and extends into a settled spell.
  • Consider lower-altitude, sheltered alternatives in the Coniston area if you're in the region, but check conditions carefully given the widespread rain.

After a very wet spell (52mm over Aug 17–20), Dow Crag has had roughly 3.5 dry days with moderate winds, which should have cleared surface moisture from exposed faces, but seepage lines fed by the heavy recent rainfall may still be running. Today is dry and clear with low humidity — a good window — but climbers should visually check for residual dampness on arrival, especially in gullies and on north-facing sections.

Based on weather conditions only — does not cover bird nesting restrictions or other access issues.

Crag Considerations
  • Dow Crag's extensive seepage lines can remain active for several days after heavy rain; the 52mm that fell Aug 17–20 will likely still be feeding damp patches on some routes, particularly in the gullies between buttresses.
  • The east/northeast aspect catches morning sun which will have aided drying on the upper faces, but lower sections and recessed areas of buttresses B and C are more sheltered and retain moisture longer.
  • At 600m the crag was likely in cloud during the humid days immediately after the rain (humidity 78–84%), which would have slowed drying despite the wind.
  • The 60+ minute approach via Walna Scar road means committing to this venue today with rain forecast from tomorrow — allow adequate time for descent before conditions deteriorate.
Warnings 2
  • Heavy rain is forecast from Aug 26 onwards — if committing to multi-pitch routes today, monitor the sky and be prepared for an earlier-than-expected weather change.
  • Seepage lines may make some routes unexpectedly slippery despite generally dry conditions; test friction carefully before committing to bold moves on any damp sections.
Reasoning
Moisture State

The rock received over 52mm of rain from Aug 17–20, followed by 3.5 essentially dry days (only trace precipitation on Aug 21–22); exposed surfaces should be dry but seepage-fed areas and sheltered recesses may retain dampness.

Drying Analysis

Moderate winds (17–20 km/h) from the north and west over the past three days combined with the east-facing aspect receiving morning sun have provided reasonable drying conditions, though humidity averaging 80% at altitude has limited evaporation rates.

Structural Risk

Non-porous BVS volcanic rock does not suffer structural weakening when wet, so hold breakage is not a concern — the risk is purely friction loss on damp surfaces.

Seasonal Factors

Mid-to-late August is within the best season for this high mountain crag; daylight hours are adequate for the long approach and multi-pitch routes, and freeze-thaw is not a concern at current temperatures.

Contributing Factors 7
Heavy recent rainfall
90%

Over 52mm fell between Aug 17–20, saturating the hillside and feeding seepage lines that take days to clear at this altitude.

Three dry days drying
85%

Essentially no rain since Aug 20, with 3.5 consecutive dry days allowing exposed rock surfaces to dry.

Today clear and dry
90%

Today is completely dry with 0% cloud cover this morning, humidity dropping to 55% by afternoon, and moderate SE winds — excellent conditions for the morning sun window on this east-facing crag.

Moderate wind aiding drying
80%

Winds of 17–20 km/h over recent days at this exposed position help clear surface moisture effectively.

Seepage line persistence
75%

Dow Crag's well-known seepage lines are likely still active after such heavy rainfall, affecting routes in gullies and on the lower buttresses.

Altitude humidity effects
70%

At 600m, average humidity has been 80%+ for much of the drying period, slowing evaporation compared to valley crags.

Rain returns tomorrow
85%

Significant rain is forecast from Aug 26 (15mm+), making today effectively the last good window for several days.

Recommendations 3
  • Arrive early to maximise the morning sun window on the east-facing buttresses and allow plenty of time for the 60+ minute approach and descent before conditions deteriorate.
  • Visually inspect routes at the base before committing — check seepage lines between buttresses and test friction on the first few moves; be prepared to switch to drier alternatives.
  • Avoid gully routes and lower sheltered sections of buttresses B and C where seepage is most likely to persist; exposed arêtes and upper faces of buttresses A and D will be driest.

After a very wet spell (52.6mm in the last 7 days, including 22.9mm on Aug 19 and 11.9mm on Aug 20), the crag has had roughly 2.5 days of near-dry weather with only trace precipitation. The exposed position and moderate winds should have cleared surface moisture from open faces, but seepage lines and sheltered areas may still be damp — a visual assessment on arrival is essential.

Based on weather conditions only — does not cover bird nesting restrictions or other access issues.

Crag Considerations
  • Dow Crag's extensive seepage lines on buttresses B and C can weep for days after heavy rain, and the 50+ mm received Aug 17–20 means some routes may still have active seepage despite surface drying.
  • The E/NE aspect catches morning sun which will aid drying on exposed faces during the first half of the day, but deeply recessed corners and north-facing walls on the buttresses will dry much more slowly.
  • The 60+ minute approach via Walna Scar road means committing significant time before you can assess conditions — if the crag is in cloud (common at 600m), friction on the volcanic rock drops significantly even from condensation alone.
  • Wind from the north today and SE tomorrow will blow across the face and aid drying, but an easterly component can push moist air directly onto the E-facing crag, potentially causing condensation.
Warnings 2
  • A major storm is forecast for Aug 27–28 with nearly 80mm of rain — do not plan any climbing for those days and expect extended drying needed afterwards.
  • At 600m with a 60+ minute approach, cloud engulfment is a real risk; if the crag is in mist on arrival, conditions will be unsuitable regardless of whether it has rained.
Reasoning
Moisture State

Surface rock on exposed faces is likely dry after ~2.5 days with only trace rain and moderate wind, but seepage zones fed by the heavy rain of Aug 17–20 (over 50mm in 4 days) may still be active, particularly on the more sheltered buttresses.

Drying Analysis

The exposed position with 19–27 km/h winds and morning sun on the E-facing aspect has provided reasonable drying conditions, though humidity averaging 90% over the past week has slowed evaporation — the single full dry day today is encouraging but marginal for a mountain crag at 600m.

Structural Risk

Non-porous Borrowdale Volcanic rock does not absorb water or suffer structural weakening, so hold breakage is not a concern; the risk is purely friction-related.

Seasonal Factors

Mid-to-late August is typically a good window for Dow Crag, though the recent unsettled spell and a major storm forecast for Aug 27–28 (80mm) narrow the usable weather window considerably.

Contributing Factors 7
Recent heavy rainfall
90%

Over 52mm fell in the last 7 days including a very wet 4-day spell (Aug 17–20) totalling 52mm, which will have recharged seepage lines extensively.

Short drying window
80%

Only ~2.5 days of essentially dry weather since the last significant rain, which is marginal for clearing seepage at a 600m mountain crag with high ambient humidity.

Exposed wind position
80%

Consistent moderate winds (19–27 km/h) across the face have significantly aided surface drying on open buttress faces.

Falling humidity today
75%

Humidity has dropped to 81% today with light northerly winds and no rain, representing the best drying conditions in over a week.

High average humidity
80%

The 7-day average humidity of 90% at crag altitude means evaporation has been sluggish and condensation is possible, especially in early morning and evening.

Non-porous volcanic rock
95%

BVS rhyolite does not absorb water, so surface drying is the only requirement — no internal moisture retention to worry about.

Tomorrow's SE wind
60%

An easterly wind component tomorrow could push moist air directly onto the E-facing crag, potentially offsetting drying gains, though humidity is forecast at a relatively low 74%.

Recommendations 3
  • Tomorrow (Aug 24) offers the best window — aim for an early start to maximise morning sun on the E-facing buttresses and allow visual assessment of seepage lines before committing to routes.
  • Favour routes on the more exposed and prominent buttresses (A and B) which dry fastest, and avoid deeply recessed chimneys, gullies, and known seepage lines.
  • Carry the mountain weather forecast for 600m altitude, not the valley forecast — be prepared to retreat if cloud descends, as condensation on BVS rock dramatically reduces friction.

Dow Crag has received over 54mm of rain in the past week, with heavy falls of 22.9mm and 11.9mm on Aug 19–20, and only one full dry day since. At 600m on an E/NE-facing crag with 91% average humidity, seepage lines will be running and surfaces are very likely still damp despite the non-porous rock.

Based on weather conditions only — does not cover bird nesting restrictions or other access issues.

Crag Considerations
  • Extensive seepage lines on the main buttresses will be actively running after 54mm of rain in the past week — these can persist for days even on non-porous rock at this altitude.
  • The E/NE aspect means the crag loses direct sun by early afternoon, significantly slowing surface drying on the lower buttresses and in gullies between them.
  • At 600m with 91% average humidity and temperatures averaging only 11°C, evaporative drying is extremely slow — cloud base frequently sits at or below crag level in these conditions.
  • The 60+ minute approach via Walna Scar road means committing significant time before conditions can be assessed; turning back wastes a large part of the day.
Warnings 3
  • Active seepage lines across all buttresses are highly likely — wet volcanic rock is extremely slippery and multi-pitch falls at this venue are serious.
  • Cloud base may sit at or below crag level given current humidity; navigation and visibility on the approach and at the crag could be poor.
  • The long approach (60+ min) means weather can deteriorate significantly before you reach the crag or during a multi-pitch route.
Reasoning
Moisture State

Heavy rain totalling 54.5mm over the past week, including 22.9mm on Aug 19 alone, with only one truly dry day since, means the crag is almost certainly still wet with active seepage lines and damp surfaces.

Drying Analysis

Despite the exposed position aiding wind-drying, the E/NE aspect loses sun by afternoon, humidity has averaged 91%, and temperatures have been low (11°C average) — drying conditions have been very poor and one dry day is insufficient to clear this volume of water.

Structural Risk

Non-porous BVS rhyolite does not suffer structural weakening when wet, so hold breakage is not a concern; the risk is purely friction loss on wet surfaces.

Seasonal Factors

Mid-August should be peak season but this has been an unusually wet and cool spell; conditions resemble autumn more than summer, and the crag is performing well below seasonal expectations for drying.

Contributing Factors 7
Heavy recent rainfall
95%

54.5mm in the past 7 days with major falls on Aug 17–20 means substantial water loading on the crag and surrounding hillside.

Only one dry day
90%

Just a single full dry day (today) since the last significant rain on Aug 20 is far too little drying time for a high mountain crag.

Very high humidity
90%

Average humidity of 91% over the past week severely inhibits evaporation and the crag is likely in cloud much of the time.

Low temperatures at altitude
85%

Averaging only 11°C at 600m, evaporative drying is much slower than it would be at valley crags in warmer conditions.

Exposed wind position
70%

The exposed position with moderate westerly winds does aid surface drying on wind-facing sections of the buttresses.

Non-porous rock type
85%

BVS rhyolite does not absorb water, so surface moisture can clear relatively quickly once conditions improve — but seepage from drainage above persists.

Rain forecast tomorrow
80%

4.7mm forecast for Aug 23 will reset any drying progress and re-wet surfaces before conditions can fully recover.

Recommendations 3
  • Do not climb at Dow Crag today or tomorrow — seepage lines will be running and surfaces will be slippery after this very wet week.
  • If conditions improve after Aug 24, consider the more sheltered and wind-exposed upper sections of B and C Buttresses which dry fastest, but visually assess all routes before committing.
  • Check the MWIS or Met Office mountain forecast for cloud base and wind chill before the long approach — valley conditions in Coniston will not reflect conditions at 600m.

Dow Crag has received 57mm of rain in the last 7 days including heavy falls of 22.9mm and 11.9mm in the past two days, with a further 2.7mm today — the crag will be thoroughly wet with active seepage lines. While a dry window begins tomorrow, the rock needs at least 24–48 hours of dry, breezy weather to shed surface moisture and seepage at this altitude and aspect.

Based on weather conditions only — does not cover bird nesting restrictions or other access issues.

Crag Considerations
  • Dow Crag's extensive seepage lines between buttresses will be running heavily after 57mm in the past week, and these can take 2–3 dry days to subside even on non-porous rock.
  • The E/NE aspect means the crag loses direct sun by early afternoon, slowing evaporation of seepage and puddles on ledges significantly compared to south-facing venues.
  • At 600m the crag is frequently in cloud — today's 82% humidity and recent 99% readings suggest the crag may still be enveloped, preventing effective drying even when rain stops.
  • The long 60+ minute approach via Walna Scar road means committing to a full mountain day — if conditions are worse than expected at the crag, retreat wastes significant time and energy.
Warnings 2
  • Active seepage lines will make many routes dangerously slippery today and likely tomorrow — friction on wet BVS rock is very poor despite its excellent dry characteristics.
  • Cloud base may sit below the crag at 600m given current humidity levels — be prepared for zero visibility and significantly colder conditions than the valley.
Reasoning
Moisture State

The rock surface will be wet today following 2.7mm of rain on top of 22.9mm and 11.9mm over the preceding two days, with seepage lines actively flowing across all buttresses.

Drying Analysis

Today's light northerly wind at 14 km/h offers minimal drying force, and the E/NE aspect with afternoon shade means the crag will retain moisture well into tomorrow even if rain stops.

Structural Risk

Non-porous BVS volcanic rock is not at risk of structural damage from moisture, so the concern is purely friction loss and slippery conditions.

Seasonal Factors

Mid-August should offer reasonable drying potential, but the current unsettled spell with high humidity (91% average over 7 days) and below-average temperatures (11.3°C) is suppressing drying rates significantly.

Contributing Factors 7
Heavy recent rainfall
95%

57mm in the last 7 days with 22.9mm on Aug 19 alone means extensive surface water and active seepage across all buttresses.

No consecutive dry days
90%

Today still recorded 2.7mm of precipitation, so the drying clock has not yet started.

High ambient humidity
85%

Average humidity of 91% over the past week severely limits evaporative drying, particularly at 600m altitude where the crag may be in cloud.

Exposed wind position
70%

The crag's exposed position will benefit from westerly and northwesterly winds forecast over the next two days, aiding surface drying once rain stops.

Non-porous rock type
90%

BVS rhyolite does not absorb water, so surface moisture will clear relatively quickly once conditions allow — no extended internal drying required.

Dry forecast window
70%

Three consecutive dry days are forecast from Aug 22–24 with dropping humidity (80% to 73%), which should progressively improve conditions.

E/NE aspect limited sun
85%

The crag only receives direct sun in the morning and is shaded from early afternoon, reducing solar drying compared to south-facing venues.

Recommendations 3
  • Wait at least until August 23 before attempting routes — two full dry days with moderate wind should clear most surface moisture, though seepage lines may still be active.
  • Check MWIS (Mountain Weather Information Service) for Lake District summit forecasts before committing to the long approach, as valley conditions are unreliable indicators at 600m.
  • If visiting on Aug 23–24, prioritise routes on the more exposed upper sections of buttresses B, C, and D which dry fastest, and avoid gully lines and lower sections where seepage concentrates.

Dow Crag has received 44mm of rain in the last 7 days including a heavy 23mm event yesterday, and today has seen further light showers with 100% cloud cover at crag altitude — the rock is almost certainly wet or damp with active seepage lines. Although a drier spell begins tomorrow, meaningful drying at 600m on this NE-facing crag will take at least 24–48 hours of dry, breezy weather.

Based on weather conditions only — does not cover bird nesting restrictions or other access issues.

Crag Considerations
  • Dow Crag's extensive seepage lines across all five buttresses will be actively running after 44mm in the past week, particularly on the Great Gully side (Buttresses C and D) where drainage channels are most pronounced.
  • At 600m with 100% cloud cover today, the crag is likely in cloud — condensation on the rock surface will delay drying even when precipitation stops.
  • The east/NE aspect means the crag loses direct sun by early afternoon, and the prevailing westerly winds are partially blocked by the ridge behind, reducing wind-assisted drying on the main face.
  • The 60+ minute approach from Coniston means committing early in the day — conditions at the crag can be dramatically worse than in the valley, so check MWIS or mountain-level forecasts before setting off.
Warnings 3
  • Active seepage lines after 44mm of recent rain make multi-pitch routes hazardous — wet volcanic rock is extremely slippery despite being structurally sound.
  • The crag is likely in cloud today with visibility potentially reduced to metres; navigation on the approach and descent requires competence.
  • Wind chill at 600m with 28 km/h winds brings effective temperature below 10°C — hypothermia risk if delayed on route in wet conditions.
Reasoning
Moisture State

With 22.9mm yesterday, 8.4mm the day before, and further light rain today totalling ~1.5mm, the rock surface and seepage lines will be thoroughly wet.

Drying Analysis

Despite moderate winds (~28 km/h today), 100% cloud cover and 87%+ humidity at altitude mean negligible evaporative drying has occurred; meaningful drying requires the clearer, drier conditions forecast from August 22nd.

Structural Risk

Rhyolite/BVS rock is non-porous and not structurally at risk from moisture, but friction is severely compromised when wet, making multi-pitch routes at this exposed mountain crag particularly hazardous.

Seasonal Factors

Mid-August offers reasonable daylight hours for the long approach but the recent unsettled Atlantic pattern has kept conditions persistently damp at mountain altitudes across the Lake District.

Contributing Factors 6
Heavy recent rainfall
95%

44mm in the past 7 days with a major 23mm event yesterday will have saturated all seepage lines and drainage features across the crag.

Ongoing light precipitation today
90%

Scattered light showers throughout the morning (1.5mm total today) are keeping surfaces wet and preventing any drying.

Persistent cloud at altitude
85%

100% cloud cover at 600m means the crag is likely enveloped in mist, depositing condensation on the rock and maintaining near-saturation humidity.

High ambient humidity
90%

Average humidity of 92% over the past 7 days and 87% today severely limits evaporative drying even in wind.

Moderate wind exposure
70%

Winds of 28 km/h today and the exposed position will aid surface drying once precipitation and cloud clear.

Improving forecast from Aug 22
70%

A dry spell with lower humidity (76%) and clearing skies from August 22nd should allow progressive drying of the crag surface.

Recommendations 3
  • Do not attempt Dow Crag today — the rock will be wet and slippery with active seepage, and the crag is likely in cloud.
  • Wait until at least August 23rd to allow two full dry days for surface and seepage drying, then assess conditions on arrival at the crag.
  • Check MWIS Lake District forecast before any visit — valley conditions in Coniston bear little relation to conditions at 600m on the crag.

Dow Crag is currently saturated after nearly 28mm of rain today on top of a very wet preceding week (47mm in 7 days). The crag will be streaming with water, in cloud, and completely unsuitable for climbing. Conditions should improve significantly from August 22nd onward as a dry spell establishes.

Based on weather conditions only — does not cover bird nesting restrictions or other access issues.

Crag Considerations
  • Dow Crag's extensive seepage lines will be running heavily after 47mm in the past week plus today's 28mm deluge — even non-porous BVS rock will have water sheeting across many routes.
  • The E/NE aspect means the crag loses direct sun by early afternoon, so even on clearing days the rock retains surface moisture longer than south- or west-facing venues.
  • At 600m the crag has been in cloud (100% humidity, 100% cloud cover) for most of today and recent days — condensation alone can keep surfaces damp even without direct rain.
  • The 60+ minute approach via Walna Scar road means committing to a full mountain day; with unsettled weather and further rain forecast tomorrow, the risk of a wasted trip is high.
Warnings 3
  • The crag is likely in cloud today with visibility potentially under 50m — route-finding on multi-pitch terrain would be extremely hazardous.
  • Seepage lines and wet ledges on the five buttresses create serious slip and fall risk on what are already committing mountain routes.
  • Streams and becks on the approach will be swollen after heavy rain — take care on the Walna Scar path.
Reasoning
Moisture State

The rock is completely saturated — 27.8mm of rain today with 100% humidity throughout the morning and persistent cloud cover at crag level, following a week of near-continuous wet weather totalling 47mm.

Drying Analysis

Despite the exposed position aiding wind-drying, the E/NE aspect and persistent cloud mean effective drying will only begin once the weather clears; with rain continuing tomorrow (8.5mm forecast), meaningful drying cannot start until August 21st at the earliest.

Structural Risk

Non-porous BVS volcanic rock is not at risk of structural damage, but the extensive surface water and seepage lines make friction dangerously poor across all buttresses.

Seasonal Factors

Mid-August should be prime climbing season, but this has been an unusually wet spell; the incoming high-pressure trend from August 22nd looks promising for a return to climbable conditions.

Contributing Factors 7
Heavy rain today
97%

Nearly 28mm of rain has fallen today with showers continuing through the afternoon, leaving the entire crag streaming wet.

Prolonged wet spell
95%

Over 47mm in the past 7 days and 118mm in 28 days has kept seepage lines active and ledges perpetually damp.

Cloud immersion at 600m
93%

100% cloud cover and near-100% humidity all day means the crag is likely in cloud, preventing any evaporative drying.

Further rain tomorrow
85%

8.5mm forecast for August 20th delays the start of any meaningful drying period until August 21st.

Dry spell from Aug 22
80%

A run of dry days with dropping humidity from August 22nd onward should allow the crag to dry out progressively.

Wind exposure aids drying
85%

The exposed position means that once rain stops and cloud lifts, wind will strip surface moisture relatively quickly from the non-porous rock.

E/NE aspect limits sun
90%

The crag only receives direct sun in the morning hours, limiting solar drying and keeping shaded areas damp longer.

Recommendations 3
  • Do not visit Dow Crag today or tomorrow — conditions are clearly unsafe with active rain, streaming rock, and near-zero visibility.
  • Target August 22nd or later when a dry window establishes; arrive early to maximise the morning sun on the east-facing buttresses.
  • Check MWIS (Mountain Weather Information Service) for the Lake District fells before committing to the long approach — valley conditions in Coniston can be misleading about conditions at 600m.

Dow Crag is currently soaked from heavy and persistent rain over the past several days, with 12.5mm falling today alone and 100% cloud cover throughout. The crag will be wet, in cloud, and dangerously slippery — conditions are wholly unsuitable for climbing today.

Based on weather conditions only — does not cover bird nesting restrictions or other access issues.

Crag Considerations
  • Dow Crag's extensive seepage lines will be running heavily after ~93mm of rain in the past 28 days; these can persist for days even after rain stops, particularly on the deeper groove lines of buttresses B and C.
  • The east/northeast aspect means the crag loses direct sun by early afternoon, and with the current westerly airflow the crag is on the sheltered (lee) side — reducing wind-drying effectiveness despite the exposed position.
  • At 600m the crag has been continuously in cloud (100% cloud cover, 96–100% humidity all day), meaning condensation alone will keep surfaces wet even during brief dry spells.
  • The 60+ minute approach from Coniston will be boggy and unpleasant after prolonged wet weather; Goat's Water outflow crossings may be higher than normal.
Warnings 3
  • The crag is currently in cloud with wet rock — climbing on wet BVS volcanic rock is extremely slippery and a serious fall risk on multi-pitch trad routes.
  • Seepage lines from the prolonged wet spell will persist for days; even when surface rock appears dry, water may be flowing across routes from above.
  • Wind chill at the crag is significant — effective temperature around 3–5°C with wet clothing; hypothermia risk in the event of an incident.
Reasoning
Moisture State

The rock is thoroughly wet from 12.5mm of rain today on top of 21.5mm in the past week and nearly 93mm in 28 days, with the crag sitting in cloud at 100% humidity throughout the day.

Drying Analysis

No meaningful drying has occurred or will occur today — persistent rain, 100% cloud cover, and near-saturation humidity at crag altitude prevent any evaporation despite moderate westerly winds.

Structural Risk

Non-porous BVS volcanic rock is not at risk of structural damage, but surface friction is severely compromised when wet, making multi-pitch trad climbing dangerous.

Seasonal Factors

Mid-August should be peak season but the current spell is unusually wet and cool for summer, with temperatures at the crag barely above 11°C and conditions more reminiscent of autumn.

Contributing Factors 5
Heavy rain today
95%

12.5mm of precipitation today with rain falling intermittently throughout, keeping all rock surfaces thoroughly wet.

Persistent multi-day rainfall
93%

Over 21mm in the past 7 days and 93mm in 28 days means seepage lines and drainage gullies will be running heavily.

Crag in cloud all day
94%

100% cloud cover and 96–100% humidity at 600m means the crag is enveloped in cloud with zero drying potential.

Cold temperatures at altitude
90%

Temperatures of only 11–12°C at crag level with 25–31 km/h winds give significant wind chill, reducing comfort and dexterity.

Strong westerly wind
85%

25–31 km/h westerly winds would normally aid drying but the crag's east-facing aspect is somewhat sheltered, and saturation humidity negates any drying benefit today.

Recommendations 3
  • Do not attempt Dow Crag today — the crag is wet, in cloud, and conditions are dangerous for friction-dependent climbing.
  • The earliest realistic window for dry conditions is August 21st after two forecast dry days, but assess conditions carefully on arrival as seepage may linger.
  • If visiting later this week, check the MWIS Lake District forecast for cloud base height — the crag at 600m is frequently above the cloud base even when valleys are clear.

Dow Crag is currently wet and will remain so for several days. Today has seen persistent 100% cloud cover with light precipitation, yesterday brought 3.1mm, and heavier rain (8.5mm total today, then 11.6mm and 7.3mm) is forecast through to August 20th — the crag will be saturated with active seepage lines and zero meaningful drying opportunity.

Based on weather conditions only — does not cover bird nesting restrictions or other access issues.

Crag Considerations
  • Dow Crag's extensive seepage lines will be running freely after the prolonged wet spell of the last three weeks (83mm in 28 days), and these take days of dry weather to subside at 600m altitude.
  • The east/NE-facing aspect means the crag loses direct sun by early afternoon, severely limiting solar drying even on clear days — and 100% cloud cover today and tomorrow eliminates solar input entirely.
  • At 600m the crag is almost certainly sitting in cloud today given 97–100% humidity and 100% cloud cover, meaning condensation is actively wetting the rock surface regardless of precipitation.
  • The 60+ minute approach via Walna Scar road in current conditions (low cloud, wet underfoot, deteriorating weather through the afternoon/evening) adds significant mountain safety risk beyond the climbing itself.
Warnings 3
  • The crag is almost certainly in cloud at 600m today with near-zero visibility — route-finding on multi-pitch climbs would be extremely hazardous.
  • Heavy rain (up to 18mm) is forecast for August 20th; Goat's Water and the approach paths will be very wet and stream crossings may be difficult.
  • Wind chill at 600m with 22–30 km/h winds and wet conditions will make effective temperatures feel well below 10°C — hypothermia risk is real on long multi-pitch routes.
Reasoning
Moisture State

The rock is wet: 3.1mm fell yesterday, 8.5mm is forecast today, humidity has been at or near 100% since early morning, and the crag is almost certainly enveloped in cloud depositing condensation on all surfaces.

Drying Analysis

There has been no meaningful drying opportunity — zero consecutive dry days, persistent cloud cover blocking solar input, and while the exposed position normally aids wind-drying, 100% humidity means the air itself is saturated and cannot wick moisture from the rock.

Structural Risk

Non-porous BVS rhyolite does not suffer structural damage when wet, so hold breakage is not a concern; the risk is purely friction loss on the slippery wet surface.

Seasonal Factors

Mid-August should be peak season but this has been an exceptionally wet spell; temperatures around 12–15°C at 600m with persistent cloud are below average and inhibit drying.

Contributing Factors 6
Active precipitation today
95%

8.5mm total forecast today with rain intensifying through the evening, ensuring the rock remains thoroughly wet.

Saturated atmosphere at altitude
93%

Humidity at 97–100% with 100% cloud cover all day means the crag is in cloud and condensation is actively wetting surfaces even between rain showers.

Prolonged antecedent wetness
90%

83mm over the past 28 days with frequent rain events means seepage lines and drainage features on the crag are fully charged.

No drying window available
92%

Zero consecutive dry days currently, and heavy rain forecast tomorrow (11.6mm) and the following days prevents any drying from beginning.

Exposed position wind drying
85%

The exposed position normally aids drying, but with saturated air at 100% humidity, wind cannot evaporate surface moisture effectively.

Non-porous rock resilience
95%

BVS volcanic rock does not absorb water or weaken structurally, so the concern is friction loss rather than permanent damage.

Recommendations 3
  • Do not attempt Dow Crag today or in the next few days — the rock is wet, the crag is likely in cloud, and conditions are deteriorating through the evening.
  • Monitor the forecast for August 21–22 when a drier window may open; the crag will need at least one full dry day with reduced humidity before friction can be trusted on the steeper buttresses.
  • Consider lower-altitude sheltered alternatives in the Lakes if you need a climbing fix — valley crags with southerly aspects will dry far more quickly after this wet spell.

Dow Crag has received rain today (1.7mm) with high humidity (95%), and the forecast shows significant rainfall arriving tomorrow and continuing through the 19th. Although the rock is non-porous and had a promising dry spell from the 10th–15th, current and incoming wet weather means surface conditions are likely damp and will worsen over the next few days.

Based on weather conditions only — does not cover bird nesting restrictions or other access issues.

Crag Considerations
  • Dow Crag's extensive seepage lines reactivate quickly after even moderate rainfall — the 73mm over the past 28 days will keep many seepage features running, particularly on the recessed B and C Buttresses.
  • The E/NE aspect catches morning sun only, meaning the crag loses direct sunlight by early afternoon, significantly slowing drying of shaded gullies and north-facing walls.
  • At 600m altitude, the crag is frequently in cloud during westerly weather patterns — today's 95% humidity and forecast SW/W winds suggest the crag may be enveloped in cloud for much of the coming days.
  • The 60+ minute approach via Walna Scar road means committing to a full mountain day; if conditions deteriorate (as forecast), retreat from multi-pitch routes is serious.
Warnings 2
  • Heavy rain (19.6mm) is forecast for the 18th — do not plan to climb on the 18th or 19th as the crag will be thoroughly wet with active seepage.
  • At 600m with forecast temperatures of 10–14°C and strong winds, wind chill will be significant; hypothermia risk exists on long multi-pitch routes if conditions deteriorate.
Reasoning
Moisture State

The rock surface is likely damp today from 1.7mm of rain combined with 95% humidity at altitude, and residual seepage from the wet period earlier in August will still be active on many lines.

Drying Analysis

Despite moderate westerly winds aiding evaporation, the E/NE aspect loses sun by afternoon and the near-saturated humidity today prevents effective drying — conditions will worsen with heavy rain forecast tomorrow and the 18th.

Structural Risk

Non-porous BVS rhyolite is not at risk of structural damage from moisture, but friction loss on wet volcanic rock is significant and the primary safety concern.

Seasonal Factors

Mid-August is typically a reasonable window for Dow Crag, but the current unsettled westerly pattern with temperatures well below seasonal average (12.5°C today at 600m) makes this a poor spell.

Contributing Factors 7
Recent rain today
85%

1.7mm of rain today with 95% humidity means the rock surface is currently damp and unlikely to dry.

Heavy rain forecast ahead
90%

19.6mm forecast on the 18th and 7.3mm on the 19th will thoroughly wet the crag and reactivate all seepage lines.

Very high humidity
85%

Humidity has been 83–98% for much of the past week and remains at 95% today, preventing effective surface drying even between showers.

Exposed wind position
70%

Strong westerly winds (18–28 km/h) help strip surface moisture when humidity drops, which will aid drying after the 20th.

Non-porous rock type
90%

BVS rhyolite does not absorb water, so once rain stops and humidity drops the surface can dry within hours in favourable conditions.

Cloud base risk at 600m
80%

Westerly/SW airflow with high humidity means the crag is very likely in or near cloud today and for the next several days, keeping the rock damp even without direct rain.

Brief dry spell 10th–15th Aug
75%

A five-day dry spell with SE winds and warmth (up to 23.7°C) would have dried the crag well, but today's rain has reset surface conditions.

Recommendations 3
  • Wait until at least the 21st when the forecast shows dry weather, lower humidity (75%), and lighter winds — conditions should allow the rock to dry properly.
  • If visiting on the 21st, prioritise the more exposed and wind-scoured upper pitches of A Buttress and E Buttress, which dry fastest; avoid recessed gullies and B/C Buttress seepage areas.
  • Check the mountain weather forecast (MWIS for Lake District) before committing to the long approach — valley conditions in Coniston will be significantly better than at crag level.
