Condition Analysis
AI-powered assessment using site data and 14-day weather history
Although today is mostly dry, the rock has had only one full dry day since 3.1mm of rain on August 25th, preceded by a wet spell (9.5mm on the 19th, 2.6mm on the 20th, and further rain on the 16th–18th). With high humidity averaging 82% over the past week and heavy rain forecast from tomorrow (22.6mm), conditions are marginal today and will deteriorate sharply; we recommend not climbing.
Based on weather conditions only — does not cover bird nesting restrictions or other access issues.
- Scattered boulders at Shaftoe dry at different rates — south-facing exposed blocks may feel surface-dry while sheltered caves, roofs, and north-facing sides (e.g. Neb Roof, Main Buttress) retain moisture far longer.
- Active community concern about damage to classic problems from wet climbing means the local ethic is strict; visibly climbing on marginal days draws justified criticism.
- The exposed hilltop setting and south aspect are the best-case scenario for drying, but overnight humidity has been consistently above 95%, which effectively halts drying and may even re-wet surfaces through condensation.
- With 32.6mm of rain in the past 28 days spread across multiple events, the cumulative moisture loading means deeper rock layers have had limited opportunity to fully dry out between wettings.
Warnings
2
- Heavy rain of 22.6mm is forecast for tomorrow (Aug 27), which will fully re-saturate the sandstone and require at least 48–72 hours of dry, windy weather before climbing is appropriate.
- Classic problems at Shaftoe are actively being damaged by climbing in marginal conditions — the community takes a very strict approach and expects climbers to err on the side of caution.
Reasoning
Rain of 3.1mm fell on August 25th and a trace (0.1mm) today, with only one intervening dry day at high humidity (80–87%), meaning exposed surfaces may be approaching dry but internal moisture is likely still present in many boulders.
The south aspect and moderate wind (~19 km/h) provide reasonable drying potential, but persistently high humidity (82% average, overnight 95%+) severely limits net evaporation, and the single dry day since the last meaningful rain is insufficient for confident drying of porous Fell Sandstone.
The cumulative wetting from multiple rain events through August (6.8mm on the 17th, 9.5mm on the 19th, 2.6mm on the 20th, 3.1mm on the 25th) means the sandstone has been repeatedly weakened, and internal moisture likely persists in less-exposed boulders, posing a real risk of hold breakage.
Summer temperatures (15–21°C) are favourable for drying, but the current unsettled pattern with above-average humidity and frequent rain events is negating much of the seasonal advantage.
Contributing Factors
6
3.1mm fell on August 25th and 0.1mm is recorded today, giving only one full dry day — well short of the 24–48 hour minimum required for even light rain on Fell Sandstone.
Average humidity of 82% over the past week, with overnight values above 95%, severely limits evaporative drying and may cause surface condensation.
Multiple rain events totalling 32.6mm over 28 days have repeatedly saturated the rock, meaning deeper layers have had little chance to fully dry between episodes.
The south-facing exposed hilltop setting is optimal for drying when conditions allow, and moderate winds (~19 km/h) help move moist air from rock surfaces.
Daytime temperatures reaching 20°C today support reasonable evaporation rates during the afternoon window.
22.6mm is forecast for August 27th with 97% humidity, which will fully re-saturate all rock and eliminate any drying progress made today.
Recommendations
3
- Do not climb today — the single dry day since rain on the 25th is insufficient for porous Fell Sandstone, especially with high background humidity.
- Avoid visiting for the rest of this week; the forecast shows heavy and repeated rain (44.2mm total) through August 31st with no meaningful drying window.
- Monitor conditions after September 1st — if the forecast dry day materialises and is followed by further dry weather with wind, conditions could recover within 48–72 hours.

Four consecutive dry days with moderate temperatures and decent wind on an exposed, south-facing hilltop have likely dried most boulders after the last rain on 20 August (2.6mm), but the preceding wet spell (19.2mm over 16–20 Aug) and average humidity of 81% mean some sheltered or north-facing problems could still hold moisture internally. Today's afternoon window looks promising but individual problem assessment is essential.
Based on weather conditions only — does not cover bird nesting restrictions or other access issues.
- Scattered boulders dry at very different rates — south-facing exposed blocks will be far drier than sheltered caves, roofs, and north-facing features like the Neb Roof and Main Buttress, which historically lag by days.
- Active damage to classic problems from wet climbing is a documented concern at Shaftoe; the local community enforces strict conditions ethics, so err on the side of caution.
- The hilltop's exposed position and south aspect are ideal for drying, but overnight humidity has been reaching 90%+ with dew formation likely, meaning early-morning rock surfaces may carry a moisture film that needs midday sun and wind to clear.
- Deep cracks, pockets, and cave features (common at Shaftoe) act as moisture reservoirs and will take significantly longer to dry than open wall and slab problems.
Warnings
2
- Active damage to classic problems from wet climbing is documented at Shaftoe — climbing on anything less than fully dry rock causes permanent, irreversible harm to this soft sandstone.
- A significant wet spell begins tomorrow and lasts through at least 29 August; conditions will deteriorate sharply and climbing should not be attempted until well after the rain stops.
Reasoning
The last significant rain was 9.5mm on 19 Aug followed by 2.6mm on 20 Aug, giving a cumulative 19.2mm over a 5-day wet spell (16–20 Aug); four dry days since with moderate wind and south aspect have likely dried exposed surfaces, but internal moisture may persist in higher-porosity blocks.
Four dry days with temperatures averaging ~17°C, wind 10–19 km/h, and a south aspect on an exposed hilltop provide good but not exceptional drying; humidity averaging 81% with overnight peaks above 90% partially offsets the wind and solar drying advantage.
The cumulative 19.2mm from the recent wet spell could leave internal saturation in sheltered or shaded boulders, posing a hold-breakage risk on problems that appear surface-dry but retain pore moisture.
Mid-to-late summer provides reasonable daylight hours and temperatures for drying, though the recent spell of cooler, humid weather has been less favourable than a typical August warm period.
Contributing Factors
6
No rain since 20 August gives four full dry days, meeting the minimum two-day rule for light rain but borderline for the heavier cumulative totals preceding.
19.2mm fell across 16–20 August, a moderate wet spell that will have saturated deeper rock layers requiring extended drying.
The exposed hilltop with south-facing aspect maximises solar radiation and wind drying, significantly accelerating moisture loss from open surfaces.
Overnight humidity has been reaching 88–96% with likely dew formation, which partially re-wets surfaces and slows net drying progress each night.
Today's forecast shows humidity dropping to 51% by early afternoon with 14–19 km/h wind and partial sun, creating a good drying window from late morning onward.
Rain is forecast from tomorrow (5.2mm) through at least 29 August with 32.8mm total, meaning today may be the last viable window for nearly a week.
Recommendations
3
- Focus on fully exposed, south-facing wall and slab problems during the afternoon (11:00–18:00) when humidity is lowest and wind is strongest; avoid caves, roofs, deep cracks, and north-facing features.
- Apply the touch test rigorously to every problem — if the rock feels cool or clammy compared to ambient temperature, or if the ground at the base is damp, do not climb.
- Be aware this is likely the last climbing window before a prolonged wet spell; do not let urgency override good judgement about individual problem conditions.

Three consecutive dry days since the last notable rain on 20 August (2.6mm), following a wetter spell of ~19mm over the preceding week, should have allowed most exposed south-facing boulders to dry given the wind and summer temperatures. However, the recent cumulative moisture load and moderate humidity mean some sheltered problems may still hold dampness, so on-site assessment is essential.
Based on weather conditions only — does not cover bird nesting restrictions or other access issues.
- Scattered boulders dry at very different rates — exposed south-facing blocks will be significantly drier than sheltered, north-facing, or vegetated ones, so each problem must be checked individually.
- The Neb Roof and cave/overhang problems are known to hold moisture for extended periods even when open faces are bone dry, as confirmed by multiple recent condition reports.
- Damage to classic problems from wet climbing is an active and well-documented concern at Shaftoe; the local community takes a strict zero-tolerance approach.
- The exposed hilltop setting at 213m provides excellent wind drying, but easterly winds forecast from tomorrow onward blow across the south-facing aspects less effectively than the prevailing westerlies.
Warnings
2
- Heavy rain is forecast for 27–28 August (37mm total); conditions will become unsafe from that point and will require several days of dry weather afterwards to recover.
- Do not assume all boulders are in the same condition — scattered blocks with different aspects and shelter can vary dramatically in dryness.
Reasoning
The last significant rain was 9.5mm on 19 August followed by 2.6mm on 20 August, giving roughly 3 full dry days by today; exposed south-facing sandstone at this site should be approaching surface and near-surface dryness, but interior moisture from the ~19mm accumulated over the prior week may linger in denser or sheltered blocks.
Three days of dry weather with moderate westerly/south-westerly winds (10–18 km/h) and summer temperatures (15–18°C) on a south-facing, exposed hilltop provide good but not exceptional drying — humidity has remained in the 75–83% range, which slows evaporation somewhat.
The rock is unlikely to be critically saturated internally given the summer warmth and wind exposure, but any problems that were seeping or ponding water could still have elevated internal moisture, posing hold-breakage risk on the small iron-oxide features.
Mid-to-late August offers reasonable drying potential with long daylight hours and moderate temperatures, though the recent pattern has been wetter and cooler than mid-summer norms, and the forecast shows a return to heavy rain by 27–28 August.
Contributing Factors
6
Three consecutive dry days since the last rain (2.6mm on 20 Aug) provide a reasonable drying window for exposed sandstone in summer.
Approximately 19mm fell over 16–20 August across multiple events, meaning the rock absorbed repeated wettings before the current dry spell began.
The south-facing hilltop setting receives strong solar radiation and good airflow, significantly accelerating surface and subsurface drying.
Average humidity over the last 7 days is 83%, which slows evaporative drying compared to ideal conditions.
Consistent winds of 10–20 km/h over the drying period help move moist air away from rock surfaces on this exposed hilltop.
Scattered boulders with different aspects, overhangs, and vegetation cover dry at very different rates, so site-wide conditions cannot be assumed uniform.
Recommendations
3
- Visit today or tomorrow and visually and tactilely check each problem before climbing — if the ground at the base of a boulder is still damp, do not climb it.
- Prioritise exposed, south-facing walls and slabs; avoid caves, roofs (especially the Neb Roof), deep cracks, and north-facing problems which will take longer to dry.
- Be prepared to walk away from specific problems that feel cool or damp to the touch, even if surrounding blocks are dry — the community here actively monitors wet-climbing damage.

Recent rain on Aug 19 (9.5mm) and Aug 20 (2.6mm) totalling 12.1mm has left only two full dry days, which is insufficient drying time for porous Fell Sandstone — especially with humidity averaging 83% over the past week and modest temperatures. While the south-facing, exposed hilltop setting aids drying, the scattered boulders at Shaftoe dry at different rates and some will still hold internal moisture.
Based on weather conditions only — does not cover bird nesting restrictions or other access issues.
- Shaftoe's scattered boulders dry at different rates — north-facing sides, caves, roofs, and deep cracks (e.g. the Neb Roof) can remain damp long after exposed south-facing walls appear dry.
- Damage to classic problems from wet climbing is an active and documented concern at this venue; the local community takes a strict approach to conditions.
- The exposed hilltop setting at 213m with south aspect and good wind exposure gives Shaftoe above-average drying potential for Fell Sandstone, but recent high humidity (83% average) has significantly blunted this advantage.
- The preceding wet spell (Aug 16–20 saw ~20.6mm across multiple days) means cumulative moisture loading is high, not just a single shower event.
Warnings
2
- Do not assume all boulders are dry because some appear dry — Shaftoe's scattered boulders dry at very different rates and classics are being damaged by wet climbing.
- Forecast rain on Aug 23, 25, 26, and 27 means a sustained dry window is unlikely this week; exercise extra patience.
Reasoning
12.1mm fell across Aug 19–20 with only two dry days since, and the preceding week included further rain on Aug 16–17, meaning the rock has had repeated wetting with cumulative internal moisture likely still elevated.
Two dry days with south aspect and moderate wind exposure provide some drying, but average humidity of 83% and temperatures around 15–17°C significantly limit evaporation rates — the standard guideline calls for 48–72+ hours of good drying conditions after heavy rain, and conditions have not been 'good' for drying.
With repeated wetting events over the past week and only partial drying, internal moisture levels likely remain above the threshold where significant strength loss occurs, posing real risk of hold breakage on the iron-oxide cemented holds climbers depend on.
Summer conditions provide the best baseline for drying, but this has been an unusually humid and showery spell for August; no freeze-thaw risk at current temperatures.
Contributing Factors

9.5mm on Aug 19 plus 2.6mm on Aug 20 represents a significant wetting event for porous Fell Sandstone, with only two dry days elapsed since.
Average humidity of 83% over the past week severely limits evaporation and slows drying even on an exposed hilltop.
20.6mm over the past 7 days across multiple rain events means repeated re-wetting before the rock could fully dry from each preceding event.
The south-facing, exposed hilltop position provides good solar radiation and wind, giving above-average drying potential for Fell Sandstone.
Today's 11.9 km/h NW wind with 75% humidity is helping drying but is not strong enough to rapidly clear moisture from the rock interior.
Temperatures around 16–17°C provide reasonable evaporation energy, though below the recent highs of 27–30°C seen earlier in August.
1.5mm forecast for Aug 23 will re-wet surfaces and reset the drying clock before the rock has fully dried from the current event.
Recommendations
3
- Wait at least one more full dry day before visiting; ideally allow until Aug 24 if tomorrow's forecast rain does not materialise, then assess conditions on arrival.
- Check individual boulders carefully — south-facing exposed walls may be climbable before caves, roofs, and north-facing sides; use the base-of-crag ground moisture test.
- Avoid the Neb Roof and other sheltered overhangs and deep cracks, which are known to hold moisture far longer than exposed faces at this venue.

Shaftoe received significant rain on 19th August (9.5mm) followed by further rain on 20th (2.6mm), with only one full dry day elapsed (today). Despite the exposed, south-facing aspect, the porous Fell Sandstone needs at least 48 hours of dry weather after this level of rainfall, and humidity has remained high (81–85%), slowing drying considerably.
Based on weather conditions only — does not cover bird nesting restrictions or other access issues.
- Scattered boulders dry at different rates — south-facing exposed blocks will dry fastest, while sheltered caves, overhangs, and deep cracks (e.g. the Neb Roof) hold moisture much longer and should be avoided even after open faces feel dry.
- Community condition reports consistently note that caves and roofs at Shaftoe lag significantly behind exposed faces, sometimes by days or even weeks in poor conditions.
- Damage to classic problems from wet climbing is an active and ongoing concern at Shaftoe — the local community takes a strict approach, and climbing on questionable rock here is considered particularly irresponsible.
- The hilltop moorland setting means ground moisture and seepage from saturated peat can wick into boulder bases even after the rain stops, prolonging damp conditions at lower sections of problems.
Warnings
2
- Do not climb today — with only one dry day since 12mm of rain and high humidity, internal moisture levels are almost certainly unsafe for porous Fell Sandstone.
- Damage to classic problems at Shaftoe from wet climbing is actively occurring; the community and BMC take this very seriously.
Reasoning
With 9.5mm on the 19th and 2.6mm on the 20th (12.1mm combined over two days), and only one dry day since, the rock is very likely still holding significant internal moisture despite any surface drying.
The south-facing, exposed aspect helps, but today's conditions (13.9°C, 81% humidity, moderate 18 km/h NW wind) provide only modest drying power — insufficient to fully dry porous sandstone after 12mm of rain in 48 hours.
Fell Sandstone loses up to 32% compressive strength on average when wet, and with probable internal saturation still above safe levels, iron oxide holds are at real risk of breakage.
Summer temperatures are favourable for drying but the recent spell has been cool for August (13–18°C) with persistently high humidity (83% average over the last week), reducing the seasonal advantage.
Contributing Factors
6
A total of 12.1mm fell across the 19th–20th August, well above the threshold requiring 48–72+ hours of dry conditions before climbing.
Only one full dry day has elapsed since the last rain, falling short of the minimum 48-hour guideline for porous sandstone after moderate rainfall.
Humidity has averaged 83% over the past week, significantly slowing evaporation and extending the time needed for internal moisture to dissipate.
The open hilltop setting with south-facing aspect and good wind exposure provides above-average drying conditions compared to sheltered or north-facing crags.
Temperatures have been below seasonal norms (13–18°C recently vs the 22–30°C seen the previous week), reducing evaporative drying rates.
Winds of 18–20 km/h today and recent days help move moist air from rock surfaces, providing some drying benefit.
Recommendations
3
- Wait at least until the 23rd August before visiting — by then there will have been 3+ dry days, and if humidity drops as forecast (~72–75%), exposed south-facing problems should be approaching safe conditions.
- On arrival, physically check individual boulders by touching the rock and inspecting the ground at the base — if the ground is damp or the rock feels cool to the touch, do not climb.
- Avoid caves, roofs, deep cracks, and sheltered overhangs (especially the Neb Roof and Main Buttress area) for longer — these features will lag well behind exposed faces.

Shaftoe Crags received 4.5mm of rain today (spread through the morning) on top of 9.2mm yesterday and 6.8mm the day before, totalling over 20mm in the last three days. The rock is certainly saturated and needs multiple dry days with good drying conditions before climbing is appropriate.
Based on weather conditions only — does not cover bird nesting restrictions or other access issues.
- Scattered boulders at Shaftoe dry at different rates — south-facing exposed blocks dry fastest, but sheltered caves, overhangs, deep cracks and north-facing aspects (e.g. Neb Roof, Main Buttress) lag significantly behind and can remain damp for days longer.
- Condition reports consistently note that even after strong winds and sunshine, roofs and sheltered features retain moisture when the rest of the crag appears dry — climbers must check individual problems rather than assuming uniform dryness.
- Active damage to classic problems from wet climbing is a known and ongoing concern at Shaftoe; the local community takes a strict stance on conditions and climbers should respect this.
- The exposed hilltop at 213m and south-facing aspect are major drying advantages, but the northerly wind forecast for the next two days blows across rather than directly onto the south faces, reducing its drying benefit somewhat.
Warnings
2
- Climbing on wet Fell Sandstone causes permanent, irreversible damage to holds — classic problems at Shaftoe are actively deteriorating due to bad etiquette.
- The surface may appear dry before the interior has dried sufficiently; if the ground at the base of boulders is still damp, do not climb.
Reasoning
The rock is thoroughly saturated after 20+ mm of rain over the past three days (6.8mm on Aug 17, 9.2mm on Aug 19, 4.5mm today), with intermittent light rain continuing through this morning — the Fell Sandstone will be at or near full saturation throughout.
Meaningful drying has not yet begun as rain was still falling this morning; even with the south aspect and exposed position, the heavy recent rainfall combined with high humidity (83% average over the last week) means at least 48–72 hours of dry weather is needed from when rain ceases.
Compressive strength is currently reduced by an estimated 30%+ due to saturation, making hold breakage a serious risk on the small iron-oxide features that define Shaftoe's problems.
Mid-August temperatures (13–18°C) and moderate winds provide reasonable drying potential once rain stops, but no freeze-thaw risk exists at this time of year.
Contributing Factors
6
Over 20mm fell in the last three days (Aug 17–20), with rain continuing through this morning, leaving the sandstone thoroughly saturated.
There have been no full dry days since the current wet spell began; today itself has seen 4.5mm of scattered precipitation.
Average humidity over the last seven days is 83%, significantly slowing evaporative drying from the rock surface.
The predominantly south-facing aspect will receive good solar radiation once skies clear, accelerating surface drying.
The exposed moorland position allows wind to move moist air away from the rock surface, which will aid drying once rain stops.
The forecast N/NW winds over the next two days are moderate (11–21 km/h) but blow across rather than directly onto south faces, providing some but not optimal drying assistance.
Recommendations
3
- Do not climb today or tomorrow — the rock is saturated and needs at least 48 hours of dry weather from the last significant rainfall.
- The earliest realistic window to assess conditions on-site is Saturday 22 August afternoon, but only if Friday remains dry as forecast; check exposed south-facing blocks first and apply the ground-moisture test.
- If visiting on the 22nd or 23rd, start with the most exposed south-facing walls and slabs and avoid sheltered caves, roofs, deep cracks, and north-facing features which will lag behind significantly.

Shaftoe Crags received rain today (3.6mm) on top of recent rain on the 17th (6.8mm) and 18th (0.3mm), meaning the rock is currently wet and has had zero consecutive dry days. Even with the exposed south-facing aspect, the sandstone needs at least 48 hours of dry weather before climbing can be considered.
Based on weather conditions only — does not cover bird nesting restrictions or other access issues.
- Scattered boulders at Shaftoe dry at different rates — individual problems must be checked rather than assuming uniform dryness, and sheltered caves/overhangs (e.g. Neb Roof) take significantly longer to dry than exposed faces.
- The community has flagged active damage to classic problems from wet climbing; local ethics here are strict and well-publicised.
- The south-facing exposed hilltop aspect is one of the fastest-drying Fell Sandstone venues, but scattered showers through today (totalling 3.6mm) have re-saturated the rock surface.
- Recent condition reports from spring show that even after strong winds and sunshine, caves and steep overhangs can remain damp for days longer than open faces — expect the same pattern now.
Warnings
2
- Climbing on wet Fell Sandstone causes irreversible hold breakage and route damage — classic problems at Shaftoe are already showing wear from bad-condition climbing.
- The rock surface may appear dry before the interior has dried sufficiently; use the ground-moisture test at the base of boulders before committing to climb.
Reasoning
The rock is currently wet: 3.6mm fell today with rain continuing into the afternoon, following 6.8mm on the 17th and 0.3mm on the 18th, giving zero consecutive dry days and a saturated surface.
Despite the south-facing exposed aspect which normally aids rapid drying, meaningful drying cannot begin until the rain stops — the forecast shows a further 0.7mm tomorrow before a sustained dry spell begins, meaning effective drying starts on the 21st at earliest.
Fell Sandstone loses up to 32% compressive strength when wet and significant weakening begins at just 1% saturation, so climbing today or tomorrow risks hold breakage and permanent route damage.
Summer temperatures (15–17°C) and moderate winds will assist drying once rain ceases, but the recent pattern of repeated wetting events has kept the rock in poor condition for days.
Contributing Factors
6
3.6mm today on top of 6.8mm on the 17th and lighter rain on the 16th and 18th means the rock has been repeatedly wetted with no sustained drying window.
The drying clock has not started — today's rain means the minimum 48-hour drying period for porous sandstone cannot begin until tomorrow at the earliest.
The hilltop setting with southern aspect and good wind exposure means drying will proceed relatively quickly once rain stops.
Average humidity over the last 7 days is 80% and today peaked at 97%, significantly slowing evaporation from the rock.
An additional 0.7mm is forecast for the 20th, delaying the start of a proper drying window until the 21st.
Temperatures of 15–18°C provide reasonable evaporative potential once rain ceases and humidity drops.
Recommendations
3
- Do not climb today — the rock is wet and climbing will cause permanent damage to the porous Fell Sandstone.
- Wait for at least 48 hours of dry weather after the last rain (likely from the 21st onwards) before considering a visit.
- On arrival after drying, check individual boulders carefully — sheltered problems, caves, and overhangs will take longer to dry than open south-facing faces.

Shaftoe Crags received rain overnight and earlier today (3mm), following 6.4mm on the 17th and further rain on the 16th — the rock is currently wet and must not be climbed. With more rain forecast tomorrow (4.5mm) and a heavy 19.7mm event on the 20th, conditions will not improve this week.
Based on weather conditions only — does not cover bird nesting restrictions or other access issues.
- Scattered boulders at Shaftoe dry at different rates — south-facing exposed blocks dry fastest, but sheltered caves, overhangs, and deep cracks (e.g. Neb Roof, Main Buttress) can remain damp for days longer than open faces.
- Community reports confirm that damage to classic problems from wet climbing is an active and ongoing concern at Shaftoe; the local ethic is strictly no climbing on damp rock.
- The exposed hilltop setting and south aspect are normally excellent for drying, but 100% cloud cover today and high humidity overnight have severely limited evaporative drying.
- Condition reports from spring show that even after strong winds and sunshine, caves and roofs at Shaftoe can lag behind open faces by several days — always check individual problems rather than assuming uniform dryness.
Warnings
2
- Climbing on wet Fell Sandstone causes permanent, irreversible damage to holds — classics at Shaftoe are already suffering from poor etiquette.
- The rock surface may appear dry before the interior has dried; do not be deceived by superficial drying after wind exposure.
Reasoning
The rock received approximately 3mm of rain overnight/early today on top of 6.4mm yesterday and 1.4mm on the 16th, giving over 10mm in the last three days with zero consecutive dry days — the sandstone is thoroughly wet internally.
Despite moderate westerly wind (~27 km/h) and south aspect, 100% cloud cover and humidity above 80% for most of today have limited drying; any surface drying is superficial and the interior remains saturated.
With recent cumulative rainfall exceeding 10mm over three days, pore saturation is likely well above the threshold where significant compressive strength loss occurs, making hold breakage a real risk.
Mid-August temperatures (~17°C) are adequate for drying in principle, but the current unsettled spell with frequent rain and high humidity is preventing the sandstone from drying out between events.
Contributing Factors
6
Over 10mm of rain across Aug 16–18 with no dry interval means the sandstone has had no opportunity to begin meaningful drying.
Today received 3mm of rain overnight, so the dry-day count resets to zero and no drying period has begun.
Humidity above 80% overnight and 100% cloud cover all day drastically reduce evaporation rates even with moderate wind.
Moderate westerly winds of 25–27 km/h across the exposed hilltop will aid surface drying once rain stops, but cannot compensate for ongoing moisture input.
The south-facing aspect would normally provide excellent solar drying in August, but total cloud cover today negates this benefit entirely.
A further 4.5mm is forecast tomorrow and a major 19.7mm event on Aug 20, ensuring the rock will be re-saturated before any meaningful drying can occur.
Recommendations
3
- Do not visit Shaftoe Crags today or in the coming days — the rock is wet and the forecast offers no adequate drying window this week.
- Monitor conditions from Aug 22 onward; if the forecast holds dry from the 21st, the earliest realistic window for exposed south-facing blocks could be Aug 23–24, but check individual problems carefully.
- If visiting later this week, use the ground-moisture test: if the soil and grass at the base of boulders is damp, the rock interior is almost certainly still wet.

Shaftoe Crags received 7.4mm of rain today with heavy showers continuing into tonight, and the forecast shows further rain on each of the next three days. The rock is currently wet and there will be no adequate drying window for several days.
Based on weather conditions only — does not cover bird nesting restrictions or other access issues.
- Scattered boulders at Shaftoe dry at different rates — south-facing exposed blocks dry fastest, but sheltered caves, roofs, and deep cracks (e.g. Neb Roof, Main Buttress) hold moisture far longer and should be treated with extra caution even after exposed faces appear dry.
- Damage to classic problems from wet climbing is an active and documented concern at Shaftoe; the local community takes a strict approach and expects climbers to err firmly on the side of caution.
- The exposed hilltop setting with strong westerly winds normally aids drying significantly, but today's light SE winds and very high humidity (93–99%) overnight and into tomorrow negate this advantage.
- Condition reports from spring 2026 confirm that even after prolonged dry spells, caves, overhangs, and north-facing aspects at Shaftoe can remain damp for days — expect similar variability after this wet spell.
Warnings
2
- Climbing on wet Fell Sandstone causes permanent, irreversible damage to holds — classic problems at Shaftoe are already showing wear from bad-condition climbing.
- The rock surface may appear dry before the interior has adequately dried; use the ground-moisture test (if soil at the base is damp, the rock is still wet inside).
Reasoning
Today's 7.4mm of rain, following 0.8mm yesterday and preceded by only a brief dry spell after earlier rain on Aug 9, means the rock is currently saturated or near-saturated, with heavy showers (up to 3.3mm/hr) continuing through tonight.
Drying has been negligible today due to light winds (3–14 km/h), high humidity (61–99%), and overcast skies; the forecast shows further rain tomorrow (1.3mm), Aug 19 (2.1mm), and a heavy 11.1mm event on Aug 20, preventing any meaningful drying until at least Aug 22.
With the rock currently wet and more rain forecast, climbing now or in the next few days risks significant hold breakage and surface erosion on the porous Fell Sandstone — precisely the damage the community has flagged as an ongoing problem.
Mid-August temperatures (14–19°C) are adequate for drying in principle, but the succession of wet days and elevated humidity will keep the sandstone in poor condition throughout the coming week.
Contributing Factors

7.4mm fell today with the heaviest showers (up to 3.3mm/hr) still to come this evening, thoroughly wetting the porous sandstone.
Further precipitation is forecast on Aug 18 (1.3mm), Aug 19 (2.1mm), and a significant 11.1mm event on Aug 20, preventing any drying reset.
Humidity has been 82–99% through today and is forecast to remain above 80% for most of the next four days, severely inhibiting evaporation.
Today's SE winds at only 3–14 km/h provide minimal drying assistance compared to the site's usual exposed westerly winds.
The south-facing hilltop aspect is the best possible orientation for drying once dry weather and wind return, which may help from Aug 22 onwards.
Recommendations
3
- Do not climb at Shaftoe today or in the coming days — the rock is wet and more rain is forecast through Aug 21.
- Monitor conditions from Aug 22 onwards when dry weather may finally arrive; allow at least 48 hours of dry, breezy weather after the last rain before visiting.
- When you do visit, test individual boulders carefully — exposed south-facing blocks will dry first, but caves, roofs, cracks, and sheltered problems will lag significantly behind.
Do Not Climb

Today saw 1.4mm of rain and the forecast brings a sustained wet spell through August 19th, totalling over 17mm of additional precipitation. While the crag had been in excellent condition after a long dry spell (August 10–15), today's rain and the incoming weather make climbing inadvisable until at least August 21st.
Based on weather conditions only — does not cover bird nesting restrictions or other access issues.
- Scattered boulders dry at different rates — south-facing exposed blocks dry fastest, but sheltered caves, roofs, and deep cracks (e.g. the Neb Roof) can hold moisture for days longer than surrounding rock.
- Damage to classic problems from wet climbing is an active and documented concern at Shaftoe; the local community takes a strict approach and climbers should respect this.
- The exposed hilltop setting and south aspect are significant drying advantages once rain stops, meaning recovery after the incoming wet spell should be relatively quick given summer conditions.
- Condition reports from March show that even after strong winds and sunshine, caves and overhangs can remain damp when open faces are dry — always check individual problems rather than assuming uniform dryness.
Warnings
2
- Active damage to classic problems from wet climbing is documented at Shaftoe — climbing on damp sandstone causes permanent, irreversible hold breakage.
- The rock surface may appear dry while remaining saturated internally after this multi-day wet spell; do not rely on surface appearance alone.
Reasoning
Today's 1.4mm of rain has re-wetted the rock surface after an excellent 6-day dry spell, and the incoming forecast of nearly 17mm over the next three days will saturate the sandstone significantly.
The preceding dry spell (Aug 10–15) with warm temperatures up to 29.6°C and moderate wind had likely dried the rock thoroughly, but today's rain and high humidity (83%) have reset the drying clock, and meaningful drying cannot begin until the wet spell ends around August 20th.
With cumulative rainfall of ~18mm expected between today and August 20th, internal moisture levels will be elevated and climbing risks hold breakage on the porous Fell Sandstone — particularly on well-trafficked classic problems already showing wear.
Mid-August summer conditions with temperatures in the mid-to-high teens and reasonable daylight hours will aid recovery once rain stops, but the cooler temperatures forecast (12°C on Aug 20th) will slow drying compared to the warm spell just passed.
Contributing Factors
6
1.4mm of rain today has re-wetted rock surfaces that were previously well-dried after a 6-day dry spell.
Forecast rain of 4.9mm, 4.5mm, 6.9mm, and 0.9mm over the next four days will keep the sandstone saturated through at least August 20th.
Humidity remains above 80% today and through the forecast wet period, severely limiting evaporative drying.
The south-facing exposed setting with consistent wind will accelerate drying once the rain stops, making recovery faster than at sheltered or north-facing venues.
Winds of 28–31 km/h forecast for August 18–19 and continuing at 23 km/h on the 20th will help begin surface drying once precipitation ceases.
Six consecutive dry days (Aug 10–15) with high temperatures (up to 29.6°C) mean the rock was deeply dried before today, which may reduce the depth of re-saturation from the current wet spell.
Recommendations
3
- Do not climb today or over the coming days until at least 48 hours of dry weather with good wind have elapsed after the last rain — realistically August 21st at the earliest.
- When conditions do improve, check individual boulders carefully: south-facing exposed blocks will dry first, while caves, roofs, deep cracks, and pockets will lag behind significantly.
- Use the practical field test — if the ground at the base of a boulder is still moist rather than sandy-dry, the rock is likely still holding internal moisture and should not be climbed.
