Condition Analysis
AI-powered assessment using site data and 14-day weather history
Dow Crag has had a very wet recent period with 72mm in the last 28 days, and today has seen light rain with 91% humidity — the crag is likely damp with active seepage lines. While three dry days earlier this week (Aug 10–13) offered some drying, today's return of moisture and a unsettled forecast through the weekend make conditions unreliable for this high mountain venue.
Based on weather conditions only — does not cover bird nesting restrictions or other access issues.
- Extensive seepage lines on the buttresses will be active after the prolonged wet spell of late July and early August, even where the main rock face appears superficially dry.
- The E/NE aspect means the crag loses direct sun by early afternoon, significantly slowing the evaporation of residual moisture on ledges and in cracks.
- At 600m with 91% humidity today, the crag is very likely in or near cloud — condensation alone can keep the rock surface damp even without rain.
- The 60+ minute approach via Walna Scar road means conditions must be reliable for the entire day, and rapid weather changes at this altitude can strand climbers on wet, slippery volcanic rock.
Warnings
2
- Active seepage lines after prolonged wet weather can make otherwise dry-looking routes dangerously slippery — test friction carefully before committing to any pitch.
- At 600m with the current weather pattern, conditions can deteriorate rapidly; carry full mountain gear including waterproofs and navigation equipment on the approach.
Reasoning
Today's 0.5mm rain on top of a very wet preceding month (72mm in 28 days) with only a brief 3-day dry window means seepage lines are almost certainly active and surface moisture is present.
The three dry days (Aug 10–13) with moderate wind and lower humidity provided some surface drying, but today's return to 91% humidity and light precipitation has re-wetted surfaces, and the NE aspect limits afternoon sun exposure that would aid drying.
Non-porous BVS rhyolite is not at risk of structural damage from moisture, but friction loss on wet volcanic rock at this grade of seriousness presents a significant safety hazard.
Mid-August is typically a reasonable window for high Lake District crags, but this summer has been notably wet, and conditions are currently more reminiscent of an unsettled autumn pattern than a settled summer spell.
Contributing Factors
6
72mm of rain in the last 28 days with multiple heavy events ensures deep seepage lines remain charged and feeding moisture onto routes.
0.5mm precipitation today with 91% humidity means surfaces are currently damp and unlikely to dry before end of day.
Three consecutive dry days (Aug 10–13) with falling humidity and moderate wind allowed some surface drying on exposed faces.
Humidity averaging 79% over the last week at 600m suggests the crag is frequently in cloud, depositing condensation even between rain events.
Consistent 20–30 km/h winds from the west and southwest aid surface drying when the rock is not in cloud.
5.4mm forecast for Aug 17 and 12.9mm for Aug 18 will re-saturate any progress made in drying, extending the wet spell further.
Recommendations
3
- Wait for a sustained dry spell of at least 2–3 days with humidity below 80% before attempting routes, particularly on the shadier buttresses (D and E).
- Check the MWIS (Mountain Weather Information Service) Lake District forecast for cloud base — if below 600m the crag will be in cloud and conditions will be poor regardless of rain.
- If visiting, consider the sunnier and more wind-exposed sections of A Buttress which catch the most morning sun and dry fastest, but be prepared to retreat if seepage is encountered.

After four consecutive dry days with warm temperatures and moderate wind, the non-porous volcanic rock at Dow Crag should have good surface conditions today, though the preceding prolonged wet spell (over 70mm in the last 28 days) means seepage lines may still be active. Conditions deteriorate from tomorrow with further rain forecast through the week.
Based on weather conditions only — does not cover bird nesting restrictions or other access issues.
- Dow Crag's extensive seepage lines can remain wet for days after prolonged rain — the 30mm+ that fell between July 25 and August 1, followed by further bursts, will still be feeding some drainage features despite recent dry days.
- The E/NE aspect catches morning sun which is the best drying window; by afternoon the crag is in shade, so aim for an early start to maximise friction and warmth on the rock.
- At 600m the crag is frequently in cloud even when the valley is clear — today's forecast shows 100% cloud cover at midday, which could mean the crag is in mist and condensation could wet the rock surface.
- The 60+ minute approach via Walna Scar road means you need to commit to a full mountain day; check MWIS or Met Office mountain forecast, not just valley conditions.
Warnings
2
- Cloud base may sit at or below crag level during midday — if the crag is in mist, rock surfaces will become slippery from condensation even without rain.
- This is a serious mountain venue with a long approach; do not underestimate the commitment required and ensure you have adequate time for descent before dark.
Reasoning
Four dry days with moderate SW/NW winds and temperatures around 15–24°C should have cleared surface moisture from the non-porous BVS rock, but residual seepage from the heavy recent rainfall (71.5mm over 28 days) may persist in drainage lines and gullies.
The exposed position and consistent 20+ km/h winds over the last few days have aided surface drying considerably, though the E/NE aspect limits direct sun to mornings only, slowing evaporation in sheltered corners and on north-facing sections of the buttresses.
Non-porous volcanic rock does not suffer structural weakening when wet, so hold breakage risk is negligible regardless of recent rainfall.
Mid-August is peak summer season with long daylight hours and generally the best conditions window for high mountain crags, though this summer has been notably wet and unsettled.
Contributing Factors
6
No significant precipitation since August 9 (4mm), with the last three days completely dry, allowing good surface drying on this non-porous rock.
Over 70mm fell in the last 28 days with multiple multi-day wet periods, likely sustaining seepage lines on the buttresses.
Persistent 20–30 km/h winds at this exposed 600m venue have significantly accelerated surface drying over the last few days.
Forecast shows 100% cloud cover during midday hours which at 600m likely means the crag is in mist, potentially depositing condensation on rock surfaces.
Valley temperatures reaching 22°C suggest crag-level temps around 18–19°C after lapse rate, warm enough for comfortable climbing and good evaporation.
Light precipitation forecast for August 14, heavier rain on August 16–17 (22mm total), closing the current weather window.
Recommendations
3
- Head up early to maximise the morning sun window on the east-facing buttresses — the rock will be warmest and driest between roughly 9am and 1pm.
- Visually inspect seepage lines before committing to routes, particularly on B and C buttresses which have known drainage features; be prepared to switch objectives if your chosen line is weeping.
- Carry warm and waterproof layers — at 600m the crag may be in cloud with a significant wind chill, and conditions can change rapidly on this exposed mountain venue.

Three consecutive dry days with moderate wind and dropping humidity today suggest the non-porous volcanic rock surface should be largely dry, but the preceding week saw repeated rain (over 10mm in the last 7 days, 71.5mm in 28 days) and high humidity, so seepage lines and sheltered recesses on this north-east-facing, 600m mountain crag may still be damp. Conditions today look promising for an afternoon window, but climbers should visually confirm dryness on arrival.
Based on weather conditions only — does not cover bird nesting restrictions or other access issues.
- Dow Crag's extensive seepage lines — particularly on buttresses B and C — can weep for days after prolonged wet spells; the recent run of rain from late July through early August means these should be checked carefully on arrival.
- The east/NE aspect catches morning sun but loses direct sunlight by early afternoon, so the best drying window is mid-morning to early afternoon — plan the 60+ minute approach accordingly.
- At 600m the crag is frequently in cloud even when the Coniston valley is clear; today's hourly forecast shows persistent high cloud cover through the morning clearing somewhat by mid-afternoon.
- Wind has been consistently moderate from the SW/W, which is broadly favourable for drying this east-facing crag, though it won't directly scour the rock face as efficiently as an easterly would.
Warnings
2
- A major rain event (19mm+) is forecast for August 16–17; do not plan multi-day trips to Dow Crag beyond August 15 without reassessing conditions.
- At 600m, temperatures will be approximately 4°C cooler than valley readings — dress for mountain conditions and carry waterproofs even on today's fair day.
Reasoning
The rock surface has had three dry days with moderate wind and today's humidity dropping to 50%, which should be sufficient to clear surface moisture on non-porous BVS rock, though deeper seepage channels fed by the 71.5mm of rain over the last month may still be active.
Moderate SW/W winds (20–27 km/h) over the last three days provide reasonable but not optimal drying for this east-facing crag; the SE wind today is more favourable, and humidity falling to 50–55% this afternoon aids evaporation.
Non-porous Borrowdale Volcanic rock does not suffer structural weakening when wet, so hold breakage from moisture is not a concern.
Mid-August is peak summer season with long daylight hours and warm valley temperatures, though at 600m the crag temperature will be roughly 4°C cooler than valley readings — still comfortable for climbing.
Contributing Factors
6
No significant precipitation since August 9 (4.0mm), with two fully dry days preceding today, allowing surface moisture to evaporate from the non-porous rock.
Over 70mm of rain in 28 days with multiple heavy events (17.6mm on July 26, 11.9mm on August 4, 6.8mm on August 5) will have charged seepage lines that take longer to clear at this altitude and aspect.
Today's humidity drops from ~70% this morning to around 50% by mid-afternoon, with warm temperatures (23°C valley-level), creating good evaporative conditions.
Consistent winds of 20+ km/h over recent days and the crag's exposed position help strip surface moisture, though the predominantly westerly winds don't directly impact the east-facing rock face.
The east-facing crag loses direct sunlight by early-to-mid afternoon, limiting solar drying and meaning shaded sections retain moisture longer than south-facing venues.
At 600m the crag can be in cloud even on otherwise fair days, and today's forecast shows persistent cloud cover through the morning which could deposit condensation on the rock.
Recommendations
3
- Target an arrival at the crag by late morning to catch any remaining direct sun and the driest afternoon conditions; the 60+ minute approach means leaving Coniston by 9–10am.
- Inspect seepage lines carefully on Buttresses B and C before committing to routes — if water is visibly running, choose routes on drier buttresses or consider retreating.
- Carry a mountain weather forecast (MWIS Lake District) and be prepared to descend quickly — light rain is forecast from tomorrow and a significant front arrives on August 16.

Dow Crag has had a very wet recent period with 29mm in the last 7 days and only one full dry day, but today is dry with moderate wind and the forecast shows an extended dry spell ahead. The non-porous volcanic rock should be drying but at 600m with high humidity and an E/NE aspect, seepage lines from the prolonged wet spell are likely still active — climbers should visually assess conditions on arrival.
Based on weather conditions only — does not cover bird nesting restrictions or other access issues.
- Extensive seepage lines on the main buttresses are likely still running after nearly 30mm of rain in the past week, particularly on Buttresses A and B which receive the least sun.
- The east-facing aspect will catch morning sun from around 06:00–13:00 in August, so the best drying window is mid-morning to early afternoon — plan the 60+ minute approach accordingly.
- At 600m the crag has frequently been in cloud recently (91% average humidity over 7 days), and today's cloud cover is high through the afternoon, which will slow drying considerably.
- The forecast SE and S winds from tomorrow onward blow directly onto the E/NE face, which will aid surface drying significantly if the crag stays clear of cloud.
Warnings
2
- Seepage lines are likely still active after the prolonged wet spell — test friction carefully before committing to any route, especially on slabs and friction-dependent moves.
- Cloud base may sit at or below crag level today given high humidity; be prepared for sudden visibility loss and route-finding difficulties on multi-pitch routes.
Reasoning
With 4.1mm of rain on August 9th and only one dry day since, the rock surface may still carry residual moisture in sheltered corners and seepage lines, though exposed faces on the non-porous BVS rock will have begun drying.
Today's moderate NW wind (~16 km/h) and the E/NE aspect receiving morning sun provide reasonable drying conditions, but high humidity (84% daily average) and persistent cloud cover above 60% are limiting evaporation rate at this altitude.
No structural risk — Borrowdale Volcanic Series rock is non-porous and does not weaken when wet; the concern is purely friction loss on damp surfaces.
Mid-summer conditions are favourable with long daylight hours and no freeze-thaw risk, but the Lake District is in a typically unsettled Atlantic pattern with frequent frontal rain.
Contributing Factors
6
Nearly 30mm fell in the last 7 days across multiple rain events (Aug 4–9), with humidity averaging 91%, meaning the crag has had very little opportunity to dry out.
BVS rhyolite does not absorb water, so drying is purely a surface process and no structural damage risk exists.
A single dry day is marginal for a 600m mountain crag with seepage lines to fully dry, especially with high ambient humidity.
At 600m with 84% humidity today and frequent cloud immersion, evaporation rates are significantly reduced compared to valley crags.
The crag's exposed position allows wind to strip surface moisture from open faces, and today's 16 km/h NW breeze will help.
The next 5+ days show zero precipitation with warming temperatures and dropping humidity, promising rapidly improving conditions.
Recommendations
3
- Tomorrow (Aug 11) is likely the first genuinely promising day — warmer (20°C), SE wind blowing onto the face, and a second full dry day; aim for an early start to maximise morning sun on the east face.
- Avoid seepage-prone routes on Buttresses A and B today; the more exposed and wind-scoured lines on Buttresses C and D will have dried fastest.
- Check the mountain weather forecast (MWIS Lake District) before committing to the 60+ minute approach — cloud base and wind chill at 600m can differ dramatically from Coniston village conditions.

Dow Crag has received 5.3mm of rain today on top of a very wet recent period (31mm in the last 7 days, 73mm in 28 days), and with high humidity (94%) and an E/NE aspect that limits afternoon drying, the rock is almost certainly wet with active seepage lines. Although rhyolite doesn't suffer structural damage, friction will be severely compromised on wet surfaces at this serious mountain venue.
Based on weather conditions only — does not cover bird nesting restrictions or other access issues.
- Dow Crag's extensive seepage lines will be running after the prolonged wet spell from late July into early August, and these can take several dry days to subside even on non-porous rock.
- The east/northeast-facing aspect means the crag loses direct sun by early afternoon, significantly slowing surface drying compared to south-facing Lake District venues.
- At 600m with recent humidity averaging 88%, the crag is frequently in cloud — condensation alone can keep surfaces damp even between rain events.
- The 60+ minute approach via Walna Scar road means committing to a full mountain day; retreating from wet multi-pitch routes on the five buttresses is serious and time-consuming.
Warnings
3
- The crag is almost certainly wet and slippery today — do not climb.
- Extensive seepage lines from the prolonged wet spell may persist for days even after surface rock appears dry.
- At 600m with a 60+ minute approach, being caught on wet multi-pitch routes is a serious situation requiring mountain rescue potential.
Reasoning
With 5.3mm of rain today, 31mm over the past week, and humidity at 94%, the rock surface is currently wet and seepage lines across the buttresses will be actively flowing.
Despite moderate SW winds (25.6 km/h) aiding surface evaporation, the E/NE aspect limits direct sun to mornings only, and with persistent high humidity the crag has had almost no effective drying time since the wet spell began around July 25th.
Rhyolite is non-porous so there is no structural weakening concern, but friction loss on wet BVS rock makes the multi-pitch routes dangerously slippery.
Mid-summer should offer the best conditions, but this has been an unusually wet and cool period for August with temperatures well below seasonal norms, reducing drying capacity.
Contributing Factors
6
5.3mm fell today atop 31mm in the last 7 days and 73mm over 28 days, ensuring the crag is thoroughly wet with active drainage.
Humidity at 94% today with a 7-day average of 88% means cloud is likely sitting on the crag, preventing any meaningful drying.
The crag only catches morning sun and is shaded from early afternoon, halving the effective solar drying window compared to south-facing crags.
Moderate to strong winds (25+ km/h) at this exposed 600m altitude will help strip surface moisture once precipitation stops.
BVS rhyolite does not absorb water so will dry relatively quickly once conditions improve, though seepage lines persist independently.
Temperatures averaging only 13°C over the past week are well below August norms, reducing evaporation rates at altitude.
Recommendations
3
- Wait at least until August 11th or 12th when two consecutive dry days with warmer temperatures (20°C+) and lower humidity should allow meaningful surface drying.
- Check the MWIS (Mountain Weather Information Service) Lake District forecast before committing to the long approach — valley conditions are no guide to crag conditions at 600m.
- If visiting later this week, carry a full set of wet-weather mountain gear and be prepared to retreat; inspect rock friction carefully on lower pitches before committing to upper buttresses.

Dow Crag has endured a prolonged wet spell with nearly 26mm in the last 7 days and only one dry day since the last significant rain; at 600m with an E/NE aspect and high humidity, seepage lines will still be active. Tomorrow brings heavy rain (13.4mm forecast), making conditions worse before they improve — the earliest realistic window is August 11th after two dry days.
Based on weather conditions only — does not cover bird nesting restrictions or other access issues.
- Dow Crag's extensive seepage lines take 2–3 dry days to clear after prolonged wet periods like the recent one, even though the volcanic rock itself is non-porous.
- The E/NE aspect catches morning sun but loses it by early afternoon, limiting the thermal drying window — particularly relevant when humidity remains above 80%.
- At 600m the crag is frequently in cloud during unsettled westerly patterns like the current one, meaning valley sunshine does not reliably indicate conditions at the crag.
- The 60+ minute approach via Walna Scar road means committing to a full mountain day — retreating from wet rock wastes significant effort and daylight.
Warnings
2
- Heavy rain (13.4mm) is forecast for tomorrow August 9th — do not attempt to climb.
- Seepage lines on the buttresses will remain active and hazardous for multi-pitch routes even after surface rock appears dry; test friction on lower pitches before committing higher.
Reasoning
With 25.8mm in the last 7 days, only one dry day elapsed, and humidity averaging 86%, the rock surfaces and seepage lines at 600m will still be wet or damp despite today's dry weather.
Today's SW wind at ~24 km/h and dry conditions will begin surface drying, but the E/NE aspect is sheltered from SW winds and the single dry day is insufficient to clear accumulated seepage from nearly two weeks of intermittent rain.
Non-porous Borrowdale Volcanic rock is not at risk of structural damage, but friction loss on damp surfaces is a serious safety concern on the multi-pitch routes here.
Mid-summer provides the best drying potential with long days and reasonable temperatures, but the current unsettled Atlantic pattern with westerlies has kept conditions cool and humid at altitude.
Contributing Factors
6
Nearly 26mm fell in the last 7 days across multiple rain events (Aug 4–7), with a broader pattern of 67.6mm over 28 days, keeping seepage lines persistently fed.
A single dry day is insufficient to clear seepage on a 600m mountain crag with an E/NE aspect, especially after such a prolonged wet period.
Average humidity of 86% over the last week severely limits evaporative drying, and the crag is likely in or near cloud at this altitude.
Moderate SW winds at ~24 km/h today provide some drying effect on exposed surfaces, though the E/NE aspect is partially sheltered from this direction.
13.4mm is forecast for August 9th, which will re-saturate the crag and reset any drying progress made today.
BVS volcanic rock does not absorb water or weaken structurally, so the concern is limited to surface friction and seepage rather than rock damage.
Recommendations
3
- Wait until at least August 11th–12th when two consecutive dry days with improving temperatures and lower humidity should allow the crag to dry sufficiently for an on-site assessment.
- Check the MWIS (Mountain Weather Information Service) Lake District forecast before committing to the long approach — valley conditions in Coniston are not representative of 600m.
- If visiting on August 11th or later, assess seepage lines carefully on arrival, particularly on buttresses B and C which are known for drainage channels, and be prepared to walk off if conditions are worse than expected.

Dow Crag has received nearly 29mm of rain in the last 7 days across multiple wet days, with the most recent significant falls on August 4–6 (25mm total), and today is still showing trace precipitation with 88% humidity. Although the rock is non-porous, extensive seepage lines will be active and surfaces are very likely still wet at this exposed, high-altitude, NE-facing crag.
Based on weather conditions only — does not cover bird nesting restrictions or other access issues.
- Dow Crag's extensive seepage lines across all five buttresses will be running heavily after 29mm of rain in the last week, and these can take several dry days to subside at 600m altitude.
- The east/NE aspect means the crag loses direct sun by early afternoon, significantly slowing surface drying even in summer — morning sun alone is insufficient to dry seepage-fed dampness.
- The 60+ minute approach via Walna Scar road is itself exposed and committing; retreating from wet conditions wastes a half-day and conditions at the crag can be dramatically worse than in Coniston village.
- High humidity (87% average over the last week, peaking at 99% on several days) suggests the crag has been in cloud frequently, preventing effective drying even between rain events.
Warnings
2
- Volcanic rock at Dow Crag becomes extremely slippery when wet — friction-dependent slab and wall routes are dangerously insecure in damp conditions.
- The long approach and 600m altitude make this a serious mountain venue; do not commit to the walk-in without checking a reliable mountain weather forecast for cloud base and wind chill.
Reasoning
Multiple rain events from July 25 through August 6 have deposited nearly 29mm in the last week alone, with humidity consistently above 88% — the rock surface and seepage lines will be thoroughly wet.
Despite moderate westerly winds aiding surface evaporation, the E/NE aspect limits solar drying to mornings only, and persistent high humidity (often 90%+) has severely inhibited drying between rain events — effectively zero consecutive dry days.
BVS rhyolite is non-porous and not at risk of structural damage from moisture, so hold breakage is not a concern.
Mid-summer conditions should be favourable, but this has been an unusually wet and cool spell for August with temperatures averaging only 12.7°C at altitude — well below seasonal norms and further reducing drying efficiency.
Contributing Factors
6
Nearly 29mm has fallen in the last 7 days across multiple events (July 31–Aug 6), with no meaningful dry window to allow the crag to shed moisture.
Average humidity of 87% over the last week, with several days at 98–99%, indicates the crag has been in cloud and surface evaporation has been negligible.
Dow Crag's well-known seepage lines will be running heavily after this sustained wet period and typically require 2–3 fully dry days to subside.
Consistent 25–37 km/h westerly winds provide some surface drying, though this is substantially offset by the persistent humidity and cloud.
Today still shows trace precipitation and there have been no fully dry days since August 2, meaning no sustained drying period has occurred.
Temperatures averaging 12.7°C at crag level are well below summer norms and reduce evaporation rates significantly.
Recommendations
3
- Wait for at least 2 full dry days with humidity below 80% before visiting — the crag needs a genuine drying window after this prolonged wet spell.
- Check the MWIS Lake District forecast on the day, not just valley weather — Dow Crag at 600m is frequently in cloud when Coniston is clear.
- If conditions improve later in the week, consider the sunnier upper sections of the A and B buttresses first, as these catch the most morning sun and dry fastest.

Dow Crag is currently wet and unsuitable for climbing. Over 30mm of rain has fallen in the last 7 days with rain again this morning, persistent 100% cloud cover, and high humidity at altitude — the rock will be thoroughly wet with active seepage lines across the buttresses.
Based on weather conditions only — does not cover bird nesting restrictions or other access issues.
- Dow Crag's five buttresses have extensive seepage lines that activate after prolonged wet weather — after 30mm+ in a week these will be running and will take several dry days with wind to clear.
- The E/NE aspect means the crag loses direct sun by early afternoon, severely limiting solar drying even on clear days — and today is fully overcast at crag level.
- At 600m the crag has been sitting in cloud (100% humidity) for much of the recent wet spell, meaning even nominally 'dry' hours provide almost no evaporative drying.
- The 60+ minute approach via Walna Scar road in current conditions (strong westerly wind, low cloud, ~9°C at the crag) makes this a serious mountain day even without climbing.
Warnings
3
- The crag is currently in cloud with strong winds and near-freezing wind chill at 600m — this is a serious mountain environment today, not just a wet crag.
- Active seepage lines after prolonged rain make even apparently dry sections of rock treacherously slippery on multi-pitch routes with limited escape options.
- Do not rely on valley weather to judge conditions at the crag — it is frequently 6–8°C colder and in cloud when Coniston village is dry and mild.
Reasoning
The rock is wet: 2.9mm fell today with rain through the early morning, following 30mm in the past week and 64mm in the past 28 days, and the crag has been at or near 100% humidity for days.
Despite strong westerly winds that would normally aid drying, persistent cloud immersion and near-saturation humidity (86% average over 7 days) have prevented meaningful evaporation — the E/NE aspect receives minimal direct sun even when skies clear.
Non-porous Borrowdale Volcanic rock is not at risk of structural damage, but friction on the crystalline surface is dramatically reduced when wet, making the multi-pitch routes genuinely dangerous.
Mid-summer should be prime season for Dow Crag, but the current Atlantic weather pattern with persistent westerly rain is typical of a Lake District wet spell; conditions may improve later this week if the forecast dry window on August 8th materialises.
Contributing Factors
7
Over 30mm in the past 7 days across multiple rain events (July 31, Aug 1, 3, 4, 5, 6) has kept the crag saturated with no meaningful dry window between showers.
2.9mm of rain fell this morning with 100% cloud cover until midday at crag altitude, meaning the rock is currently wet.
Average humidity of 86% over the past week with the crag frequently in cloud prevents effective evaporative drying even during rain-free hours.
35 km/h westerly winds at this exposed crag would normally accelerate surface drying, but the effect is negated by persistent cloud immersion and ongoing precipitation.
The east-facing crag only catches morning sun and today's full cloud cover eliminates even that, providing no solar drying assistance.
After a sustained wet period of 64mm in 28 days, Dow Crag's extensive seepage network will be actively draining across the buttresses, making many routes unclimbable regardless of surface conditions.
A further 3.1mm is forecast for August 7th, extending the wet period before any potential drying window.
Recommendations
3
- Do not visit Dow Crag today or tomorrow — the rock is wet, seepage lines are active, and conditions are genuinely dangerous for multi-pitch climbing.
- The earliest realistic window is August 8th if it stays dry as forecast, but even then assess conditions carefully on arrival as seepage may still be running.
- Consider lower-altitude, sheltered venues in the Coniston area or wait for the potential clearing trend from August 11th onwards.

Dow Crag is currently wet and in cloud, with heavy rain falling throughout the morning and 100% humidity saturating the rock surface. Tomorrow brings a severe 33.5mm deluge, and the following days offer only brief and incomplete drying before further rain returns — conditions are unsuitable today and will remain poor for most of the coming week.
Based on weather conditions only — does not cover bird nesting restrictions or other access issues.
- Dow Crag's extensive seepage lines will be running hard after the recent wet spell (18mm in the last 7 days plus today's 7mm), and the forecast 33.5mm tomorrow will keep them active for days.
- The E/NE aspect means the crag loses direct sun by early afternoon, significantly slowing drying at 600m — even on a clear day, sheltered gullies and recesses between the five buttresses hold moisture.
- At 600m altitude the crag is currently sitting in cloud (100% cloud cover and 100% humidity all day), which prevents any evaporative drying even during rain-free hours.
- The 60+ minute approach via Walna Scar road means committing to mountain conditions well in advance — with rapidly changing weather and poor visibility, retreat options are limited once on multi-pitch routes.
Warnings
3
- Extremely poor visibility expected at crag level today and tomorrow — 100% cloud cover at 600m with near-zero visibility in heavy rain.
- 33.5mm of rain forecast tomorrow with 41 km/h winds creates serious mountain safety concerns beyond just climbing conditions — avoid the hill entirely on August 5th.
- Multi-pitch routes on wet BVS rock are treacherously slippery; a fall on the friction-dependent slabs could be serious given the mountain setting and long rescue times.
Reasoning
The rock is thoroughly wet: intermittent rain has fallen all morning with 7.3mm today on top of a prolonged wet period (18mm in the past week), and 100% humidity at crag level prevents any surface drying.
Despite moderate winds (17–27 km/h), persistent 100% humidity and full cloud immersion negate any wind-driven evaporation, and the E/NE aspect receives no afternoon sun to assist drying.
Non-porous BVS rhyolite is not at risk of structural damage, but surface friction is critically compromised when wet — the primary hazard is slippery rock on multi-pitch mountain routes.
Mid-summer should be prime season for Dow Crag, but an unusually wet and cool spell with temperatures 5–8°C below seasonal norms has kept the crag in persistent cloud and moisture.
Contributing Factors
6
Over 7mm of rain has fallen or is forecast today, with showers continuing through the afternoon and 100% humidity throughout.
18.3mm in the past 7 days with only one truly dry day means seepage lines and drainage channels are already charged with water.
33.5mm forecast for August 5th with 100% humidity and 41 km/h winds will completely saturate the crag and recharge all seepage systems.
100% cloud cover at crag altitude all day prevents solar drying and maintains surface condensation on the rock.
Strong winds (20–27 km/h today, 41 km/h tomorrow) would normally aid drying but are ineffective when humidity is at or near 100%.
BVS volcanic rock does not absorb water so will dry relatively quickly once rain stops and humidity drops — but friction loss while wet makes climbing dangerous.
Recommendations
3
- Do not visit Dow Crag today or tomorrow — the crag is wet, in cloud, and a major storm is forecast for August 5th.
- The earliest possible window is August 7th, but check the MWIS or Met Office mountain forecast for cloud base and humidity at 600m before committing to the long approach.
- Consider lower-altitude sheltered venues in the Coniston or Langdale valleys if desperate to climb this week, as conditions at 600m will be persistently poor.

Dow Crag has been through a prolonged wet spell (nearly 30mm over the past week) with very high humidity, and today saw early-morning rain followed by a drying window through the afternoon. However, with 100% cloud cover much of the day at 600m, extensive seepage likely persists, and heavy rain is forecast from tomorrow onwards — conditions are marginal at best and deteriorating.
Based on weather conditions only — does not cover bird nesting restrictions or other access issues.
- Dow Crag's extensive seepage lines will be running heavily after ~30mm of rain in the past 7 days at high humidity — even non-porous BVS rock will have wet streaks across many routes.
- The east/NE-facing aspect means the crag loses direct sun by early afternoon, limiting the drying window even on the clearest days.
- At 600m with 100% cloud cover for much of today, the crag is likely in and out of cloud, depositing additional surface moisture via condensation.
- The 60+ minute approach from Coniston means climbers arriving for the brief afternoon clearing window will have limited usable time before conditions worsen again.
Warnings
2
- Extensive seepage lines are likely active across all buttresses after the prolonged wet period — wet volcanic rock is extremely slippery and falls on multi-pitch routes here have serious consequences.
- The crag is likely in and out of cloud today; visibility and conditions at 600m may be very different from the valley — check the MWIS Lake District forecast before committing to the walk-in.
Reasoning
With 13.9mm in the past 7 days, 99% humidity on multiple recent days, and light rain this morning, the rock surface and seepage lines are almost certainly still wet despite a midday drying window.
A brief clearing from roughly midday to late afternoon today with ~20°C temps, moderate east wind, and low humidity (~50%) provides some drying, but this follows days of saturation and the E/NE aspect loses sun by mid-afternoon — insufficient to fully dry seepage lines.
Non-porous BVS rhyolite does not suffer structural weakening when wet, so hold breakage is not a concern.
Mid-summer conditions should be favourable, but this August has been unusually cool and wet with temperatures 5–8°C below seasonal norms at altitude, slowing evaporation significantly.
Contributing Factors

Nearly 30mm fell between July 25–August 1 with humidity at or near 99% on multiple days, saturating the ground and feeding seepage lines extensively.
Today's midday-to-evening period shows clearing skies, dropping humidity (~50%), and moderate east winds around 19 km/h, which will begin drying exposed surfaces.
At 600m the crag was likely in cloud for much of this morning (100% cloud cover, 80%+ humidity), depositing condensation on rock surfaces.
8.1mm is forecast for August 4 with 96% humidity, meaning any drying achieved today will be immediately reversed.
Recent average temps of 13°C at altitude are well below summer norms, reducing evaporation rates and extending drying times for seepage.
Moderate to strong winds (20–25 km/h) at the crag help strip surface moisture from exposed faces, though sheltered gullies and corners will remain damp.
Recommendations
3
- Do not climb today — while a brief afternoon clearing exists, seepage from the prolonged wet spell makes most routes unacceptably slippery at this mountain crag.
- Monitor conditions closely but realistically expect the coming week to remain poor, with significant rain forecast on Aug 4, 5, 6, and 8.
- Consider lower-altitude, quick-drying valley crags in the Lakes such as Shepherd's Crag or Chapel Head Scar as alternatives during this unsettled spell.
