Condition Analysis
AI-powered assessment using site data and 14-day weather history
Shaftoe Crags have received repeated rainfall over the past two weeks (44.4mm in 28 days, 11.7mm in the last 7 days alone) with no meaningful dry spell — today itself has had light rain and 88% humidity. The porous Fell Sandstone will be holding significant internal moisture despite the exposed, south-facing aspect, and conditions are not suitable for climbing.
Based on weather conditions only — does not cover bird nesting restrictions or other access issues.
- Scattered boulders dry at different rates — south-facing exposed walls may feel surface-dry while sheltered caves, roofs, deep cracks, and pockets (e.g. Neb Roof, Main Buttress) retain moisture far longer.
- Community condition reports from earlier in the year confirm that even after strong winds and sun, overhanging features and caves at Shaftoe can remain damp for days to weeks — the current unsettled pattern will be worse.
- Damage to classic problems from wet climbing is an active and documented concern at Shaftoe; the local community takes a strict approach, and holds on popular lines are already showing wear from poor-condition ascents.
- The hilltop exposure and south aspect are genuine advantages for drying, but humidity has averaged 82% over the past week, severely limiting evaporative drying even with moderate wind.
Warnings

- Climbing on wet Fell Sandstone causes permanent, irreversible damage to holds — classic problems at Shaftoe are already showing wear from poor-condition ascents.
- The rock surface may feel dry to the touch while remaining saturated internally; do not rely on surface appearance alone — check the ground at the base of boulders and test pockets and cracks for dampness.
Reasoning
Repeated rain events from June 1–16 (totalling ~36mm with no consecutive dry period longer than about 36 hours) mean the sandstone is likely saturated well beyond surface level, with internal moisture posing both structural and safety risks.
Despite the south-facing, exposed aspect and moderate winds (17–37 km/h), average humidity of 82% and persistent cloud cover (100% today) have severely curtailed evaporative drying, and no gap of 48+ dry hours has occurred since late May.
With repeated wetting cycles and no adequate drying intervals, the sandstone holds — especially iron-oxide-cemented features — are at elevated risk of grain loosening and breakage, which would cause permanent damage to classic problems.
Early June should offer improving conditions, but this has been an unusually wet and cool spell for the time of year, with temperatures averaging only ~11°C over the past week — well below seasonal norms and further slowing drying.
Contributing Factors

11.7mm in the last 7 days across multiple events with no dry spell exceeding ~36 hours means the rock has been repeatedly re-wetted before it could dry internally.
Average humidity of 82% over the past week (peaking at 90%) dramatically reduces net evaporation from the rock surface, stalling drying even with wind.
100% cloud cover all day eliminates direct solar radiation on the south-facing boulders, removing one of the site's key drying advantages.
Moderate to strong winds (17–37 km/h recently) across the exposed moorland provide the main drying mechanism, partially offsetting high humidity.
The south-facing orientation would normally accelerate drying, but persistent overcast skies negate much of this benefit currently.
Average temperatures of ~11°C over the past week are below seasonal norms, slowing evaporation rates significantly compared to typical early summer conditions.
Today's 0.8mm of scattered light rain resets any drying progress and means the dry-clock effectively restarts from this evening at best.
Recommendations
3
- Do not climb at Shaftoe today — the rock has been repeatedly wetted over the past two weeks with no adequate drying window, and internal moisture will be high.
- Wait for a minimum of 48 hours of genuinely dry weather (sub-75% humidity, some sunshine) before visiting; check individual boulders carefully on arrival, particularly sheltered features.
- Monitor the forecast closely — the coming week shows continued unsettled weather, so a visit may need to wait until a more sustained dry spell develops.

Shaftoe Crags has experienced a prolonged wet period with 42mm of rain over 28 days and frequent small showers continuing through today, leaving the porous Fell Sandstone insufficiently dried. With rain forecast today from 20:00 and further rain every day through June 20th, there is no adequate drying window for the rock to reach a safe internal moisture state.
Based on weather conditions only — does not cover bird nesting restrictions or other access issues.
- Scattered boulders dry at different rates — exposed south-facing slabs may feel surface-dry while sheltered caves, cracks, and north-facing sides of boulders retain deep moisture from the prolonged wet spell.
- Community condition reports from earlier in 2026 highlight that the Neb Roof, Main Buttress caves, and deep cracks are the slowest features to dry, often remaining damp long after exposed faces appear dry.
- The site has an active damage problem: classics are being worn by climbing in marginal conditions, and the local community takes a strict approach — the ethical bar here is higher than at many venues.
- Despite the exposed hilltop setting and south aspect aiding drying, the cumulative 42mm over 28 days with very few consecutive dry days means internal saturation levels are likely elevated across most boulders.
Warnings
2
- Climbing on wet Fell Sandstone causes permanent, irreversible damage to holds — classics at Shaftoe are already showing wear from climbing in poor conditions.
- The rock surface may appear dry during today's afternoon window while remaining saturated internally; surface appearance is not a reliable indicator of safety after prolonged wetting.
Reasoning
With 11.6mm in the last 7 days spread across multiple events (most recently 1.5mm on June 12, 0.3mm on June 13, and 1.0mm forecast today), and 42mm over 28 days with almost no multi-day dry spells, the rock's internal moisture content is very likely above safe thresholds despite any surface drying.
The longest dry spell in the past two weeks was only about 36 hours (June 14–15 daytime), which is far too short for porous Fell Sandstone to dry internally after cumulative heavy wetting; the south aspect and moderate wind help surface evaporation but cannot overcome persistent re-wetting.
With repeated wetting cycles keeping internal moisture elevated, the 10–50% compressive strength reduction in wet Fell Sandstone poses a real risk of hold breakage, particularly on the well-trafficked classic problems the community has flagged as already showing damage.
June temperatures (7–18°C range) are adequate for some drying but the persistently high humidity (81% average over the last week) significantly slows evaporation, and the ongoing unsettled weather pattern shows no sign of the sustained dry spell needed to properly dry the rock.
Contributing Factors
6
42mm over 28 days with rain on most days means the sandstone has had almost no opportunity to dry internally, keeping pore saturation dangerously high.
Zero consecutive dry days as of today, with the last meaningful dry spell being only June 13–14, far short of the 48–72+ hours needed after heavy cumulative wetting.
81% average humidity over the past week severely limits evaporation rates even when rain isn't falling.
Rain is forecast every day from June 16–20 (totalling 15.8mm), ensuring no drying window in the coming week.
The exposed hilltop and south-facing aspect provide the best possible drying conditions for Fell Sandstone, but this cannot compensate for persistent re-wetting.
Winds of 10–17 km/h through the afternoon aid surface drying, though today's rain from 20:00 will negate any progress.
Recommendations
3
- Do not climb at Shaftoe today or in the coming days — the prolonged wet spell and continued forecast rain mean the Fell Sandstone is almost certainly retaining dangerous levels of internal moisture.
- Monitor the forecast for a sustained dry spell of at least 3 consecutive dry days with wind and low humidity before considering a visit, given the cumulative saturation.
- If you do visit to walk and check conditions, use the ground-moisture test: if the soil at the base of boulders is not sandy-dry, the rock is not ready to climb.

Despite one dry day today, the preceding two weeks have seen frequent rain totalling over 40mm, with the most recent precipitation (0.3mm) only yesterday and heavier falls on June 11–12. The porous Fell Sandstone at Shaftoe will still hold significant internal moisture, and with more rain forecast tomorrow, conditions are not suitable for climbing.
Based on weather conditions only — does not cover bird nesting restrictions or other access issues.
- Shaftoe's scattered boulders dry at very different rates — exposed south-facing slabs may feel dry while sheltered caves, roofs, and north-facing sides remain saturated internally.
- The community has documented ongoing damage to classic problems (e.g. Neb Roof) from climbing in marginal conditions; local ethics demand a strict approach.
- The exposed hilltop setting and strong recent winds (30–37 km/h) do aid surface drying, but the cumulative 41mm over 28 days means deep moisture is likely still present in many blocks.
- Condition reports from drier spells earlier in the year noted that caves, overhangs, and deep cracks lag far behind exposed faces — expect the same pattern now after this wet spell.
Warnings
2
- Active damage to classic problems from wet climbing has been documented — climbing today would contribute to irreversible erosion of holds.
- The rock surface may appear dry in places while internal saturation remains dangerously high; do not trust surface appearance alone.
Reasoning
With 12.7mm in the last 7 days spread across multiple events and only one fully dry day, the rock is very likely still holding significant internal moisture despite any surface drying.
The south aspect and exposed hilltop with decent wind (18–37 km/h) provide above-average drying potential, but only one dry day after repeated wetting is far short of the 48–72+ hours needed after this volume of rain.
Cumulative wetting over the past two weeks has likely kept internal saturation well above the critical threshold where compressive strength is significantly reduced, making hold breakage a real concern.
Early June temperatures (averaging ~11°C over the last week) are cooler than expected for the season, slowing evaporation rates and extending required drying time.
Contributing Factors
7
Over 40mm across the last 28 days with rain on 10 of the last 14 days means the sandstone has been repeatedly re-saturated with no extended drying window.
Just one consecutive dry day since the last precipitation (0.3mm on June 13) is far below the minimum 24–48 hours needed even after light rain.
Average humidity of 80% over the last week severely limits evaporation rates and keeps surface moisture from escaping efficiently.
The hilltop exposure and south aspect provide the best possible natural drying conditions for Northumberland sandstone.
Wind speeds of 18–37 km/h over recent days help move moist air away from rock surfaces and accelerate surface drying.
3.2mm forecast for June 15 and 6.7mm on June 16 will re-wet any surfaces that have begun to dry, resetting the drying clock.
Temperatures averaging 11°C over the past week are cool for June, reducing evaporation rates compared to typical summer conditions.
Recommendations
3
- Do not climb today — the rock has had only one dry day after a prolonged wet spell and will still be holding dangerous levels of internal moisture.
- Monitor conditions after the forecast rain clears around June 18–19; a sustained dry spell of at least 48 hours with wind will be needed before reassessing.
- When you do visit, test individual boulders carefully — check the ground at the base of each block, and if it is not bone-dry sandy soil, the rock above is almost certainly still too wet.

Despite the south-facing aspect and exposed position, Shaftoe has received frequent light-to-moderate rain over the past two weeks (41.7mm in 28 days) with the most recent precipitation today (0.9mm on June 13). The rock has had no consecutive dry days to build a proper drying window, and the porous Fell Sandstone is likely still holding internal moisture from the cumulative wetting.
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 slabs may appear dry while sheltered caves, cracks, and north-facing sides of blocks remain damp internally.
- Classics at Shaftoe are actively being damaged by wet climbing; the local community takes a strict 'when in doubt, don't climb' approach.
- The Neb Roof and other steep overhangs are historically the slowest features to dry and may retain moisture for days longer than open walls.
- The hilltop's strong wind exposure (averaging 25+ km/h recently) is the main positive drying factor, but high humidity (80% average last 7 days) is limiting its effectiveness.
Warnings
2
- Damage to classic problems from wet climbing is an active and documented concern at Shaftoe — do not climb if any doubt exists about conditions.
- Surface-dry appearance is unreliable after this pattern of repeated wetting; internal moisture can persist well beyond what the surface suggests.
Reasoning
Cumulative rainfall of ~13mm over the last 7 days with rain on 5 of the last 7 days means the sandstone has been repeatedly re-wetted with no sustained drying window, and internal moisture levels are likely elevated despite surface appearance.
The south-facing aspect and strong westerly winds (20–36 km/h) would normally provide excellent drying, but persistently high humidity (80% average) and repeated rain events have prevented effective cumulative drying — only partial surface drying has occurred between showers.
With repeated wetting cycles and no extended dry period, internal pore saturation may be significant enough that climbing risks grain loosening and hold breakage on the iron-oxide features climbers depend on.
Early June temperatures (11–18°C) are adequate for drying but below seasonal norms, and the prolonged unsettled pattern since early June has kept the sandstone in a vulnerable state despite the nominally favourable season.
Contributing Factors
6
Rain has fallen on 5 of the last 7 days totalling ~13mm, with no window of more than one consecutive dry day to allow meaningful internal drying.
Humidity has averaged 80% over the past week with peaks of 90%, severely limiting evaporative drying even in wind.
0.9mm of rain today means the rock surface has been re-wetted with zero dry days heading into the assessment period.
Sustained winds of 20–36 km/h on the exposed hilltop are the primary drying driver and will help surface moisture evaporate relatively quickly.
The southerly aspect maximises solar gain during long June days, aiding surface drying on exposed faces.
41.7mm over 28 days with an especially wet period from June 1–12 means the rock has been in a near-continuously moist state, raising internal saturation levels.
Recommendations
3
- Wait for at least 48 hours of genuinely dry weather with low humidity before visiting; the current pattern has not provided this.
- If you do visit after a dry window opens, test the ground at the base of each boulder — if the soil or moss is damp, the rock is still too wet to climb.
- Focus attention on the most exposed south-facing slabs and walls first, as caves, roofs, cracks, and sheltered features like the Neb Roof will take significantly longer to dry.

Shaftoe Crags have received frequent rainfall over the past two weeks (nearly 46mm in 28 days), with 6.4mm falling today and significant rain on several recent days. Despite the exposed, south-facing aspect, the rock has had virtually no consecutive dry days to recover, and the porous Fell Sandstone will be saturated internally even where surfaces may begin to appear dry.
Based on weather conditions only — does not cover bird nesting restrictions or other access issues.
- Scattered boulders dry at different rates — some sheltered or north-facing blocks will hold moisture far longer than exposed south-facing walls, so uniform assumptions are dangerous.
- The community has flagged active damage to classic problems from wet climbing; local ethics here are strict and damage is already occurring to iconic lines.
- Caves, roofs, and deep cracks (e.g. Neb Roof, Main Buttress) are known to retain moisture for days or even weeks longer than exposed faces, as noted in recent condition reports.
- The recent pattern of repeated light-to-moderate rainfall events (June 1–12) means the rock has been repeatedly re-wetted before any meaningful internal drying could occur.
Warnings
3
- Climbing on wet Fell Sandstone causes permanent, irreversible damage to holds — classics at Shaftoe are already suffering from bad-conditions climbing.
- The rock surface may appear dry before the interior has dried — do not rely on visual or touch assessment alone; check the ground at the base of boulders as an indicator.
- Weakened holds on saturated sandstone pose a serious risk of unexpected breakage and climber injury.
Reasoning
With 6.4mm of rain today, 5.4mm yesterday, and frequent precipitation throughout the past 12 days totalling over 25mm, the sandstone will be deeply saturated well beyond the critical 1% threshold where significant strength loss begins.
Despite the south-facing aspect and good wind exposure (29 km/h today), zero consecutive dry days means drying has been repeatedly interrupted; the strong wind will help surface evaporation but cannot address deep internal saturation accumulated over nearly two weeks of intermittent rain.
The rock is at high risk of hold breakage and grain loosening given the prolonged saturation period — climbing now would cause permanent damage to the porous Fell Sandstone and endanger the climber through weakened holds.
Early June temperatures averaging only 11°C over the past week are below seasonal norms for drying, though freeze-thaw risk is negligible at this time of year.
Contributing Factors
6
6.4mm fell today following 5.4mm yesterday and repeated rain events since June 1, keeping the rock in a near-continuously wet state.
The rock has not had a single full dry day since at least June 4, preventing any meaningful internal drying.
Over 25mm of rain in the past 12 days will have driven moisture deep into the porous sandstone, requiring extended dry weather to evacuate.
The exposed hilltop setting with south-facing aspect and strong westerly winds (29+ km/h) will accelerate surface drying once rain stops.
Average humidity of 82% over the past week significantly slows evaporative drying from the rock surface.
Average temperatures of only 11°C over the past week are below seasonal expectations and reduce drying rates.
Recommendations
3
- Do not climb today — the rock is wet from today's rain and deeply saturated from the prolonged wet spell.
- Wait for at least 48–72 hours of continuous dry, breezy weather before considering a visit, and even then test individual boulders carefully.
- When conditions do improve, prioritise exposed south-facing walls and slabs; avoid caves, roofs, deep cracks, and sheltered blocks for significantly longer.

Shaftoe Crags received 6.1mm of rain today (mostly mid-morning through early afternoon) on top of a very wet recent period totalling nearly 40mm over 28 days, with repeated wetting events preventing proper drying. The rock will be thoroughly saturated and unsafe to climb today and likely for the next 48+ hours.
Based on weather conditions only — does not cover bird nesting restrictions or other access issues.
- Scattered boulders dry at different rates — exposed south-facing walls will dry first, but sheltered caves, roofs, and north-facing aspects (like the Neb Roof and Main Buttress) can stay damp for days longer, as confirmed by local condition reports.
- Active damage to classic problems from wet climbing is an ongoing community concern at Shaftoe; the local ethic is strict and climbers should respect this.
- The exposed hilltop setting and strong westerly winds forecast for June 12–13 (35–36 km/h) will significantly accelerate surface drying, but repeated soakings over recent weeks mean internal moisture levels will be high.
- Ground conditions at the base of boulders are a useful proxy — if the soil or turf is still damp, assume the rock is too.
Warnings
2
- Climbing on wet Fell Sandstone causes permanent, irreversible damage to holds — classic problems at Shaftoe are actively deteriorating due to wet climbing.
- The rock surface may appear dry while the interior remains dangerously saturated — do not rely on visual assessment alone after such a prolonged wet spell.
Reasoning
The rock has been subjected to repeated rainfall events over the past 10 days (cumulative ~28mm from June 1–11), with today's 6.1mm being the heaviest single day, meaning the sandstone is deeply saturated internally despite any brief surface drying between showers.
Although the south aspect and exposed hilltop position favour fast drying, the repeated re-wetting cycle has prevented the rock from ever fully drying out — the last genuinely dry spell was late May, and even then only 0.3–0.6mm trace rain interrupted it — so the porous Fell Sandstone will need at least 48–72 hours of dry, windy weather from the last significant rain to approach safe conditions.
With cumulative saturation from weeks of intermittent rain, internal moisture levels are likely well above the ~1% threshold where significant strength loss begins, creating real risk of hold breakage and grain loosening on the iron-oxide-cemented holds.
Early June conditions are warmer than spring but the recent cool, humid spell (average 11°C, 80% humidity over the last week) has limited evaporation rates, and the moderate altitude of 213m contributes to slightly cooler temperatures than lowland sites.
Contributing Factors
6
6.1mm of rain fell today primarily between 09:00–15:00, thoroughly wetting all rock surfaces and re-saturating porous sandstone.
Nearly 40mm over the past 28 days with frequent re-wetting events means the rock has never fully dried internally during this period.
Average humidity of 80% over the past week with today peaking at 94% has severely limited evaporative drying between rain events.
The south-facing aspect receives good solar radiation and will aid drying once dry weather establishes.
Forecast westerly winds of 35–36 km/h on June 12–13 will significantly accelerate surface drying on this exposed hilltop.
Recent average temperatures around 11°C and forecast highs of only 15–17°C for the next two days limit evaporation rates compared to warmer summer conditions.
Recommendations
3
- Do not climb today or tomorrow — the rock is saturated from today's rain and the prolonged wet period, and needs at least 48 hours of dry, windy weather.
- Target June 14 at the earliest for a visit, but check exposed south-facing boulders individually and test the ground at the base for dampness before committing.
- Avoid caves, roofs, deep cracks, and north-facing aspects (e.g. Neb Roof, Main Buttress) for several days longer than open walls, as these features retain moisture far longer.

Shaftoe Crags have received over 23mm of rain in the last 7 days across multiple events, with further showers today (4mm) and rain still falling intermittently this afternoon. The porous Fell Sandstone will be thoroughly saturated internally and needs a sustained dry spell before climbing is appropriate.
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 first, but sheltered caves, roofs, and north-facing sides (e.g. Neb Roof, Main Buttress) can hold moisture for days longer, as condition reports consistently confirm.
- The community has documented active damage to classic problems from wet climbing at Shaftoe; local ethics are strict and climbers are expected to err heavily on the side of caution.
- The exposed hilltop setting and south aspect are significant advantages for drying, but cumulative rainfall of 23mm over the past week with humidity averaging 81% means even these favourable factors cannot compensate yet.
- Ground conditions at the base of boulders are a reliable proxy — if the moorland turf and soil around blocks is still damp, the rock interior is almost certainly still holding moisture.
Warnings
2
- Climbing on saturated Fell Sandstone causes permanent hold breakage and route degradation — damage to classics at Shaftoe is already an active concern documented by the local community.
- Surface-dry rock can mask dangerous internal saturation; do not rely on a quick visual check after this much cumulative rainfall.
Reasoning
With 23.1mm over the past 7 days across multiple rain events (June 1–4, 6, 8, and today), the sandstone will be deeply saturated well beyond the critical 1% threshold at which significant weakening begins.
Although the south aspect and exposed hilltop setting with decent winds (18–33 km/h) aid drying, there has been no consecutive dry period longer than about 36 hours in the past week, meaning the rock has had no opportunity to begin meaningful internal drying between repeated wettings.
The repeated saturation cycles over the past 10 days pose a serious risk of grain loosening and hold breakage, with compressive strength likely reduced by 30%+ across most boulders — climbing now would risk permanent damage to classic problems.
Early June temperatures (averaging ~12°C) are moderate and there is no freeze-thaw concern, but the persistent unsettled pattern with high humidity (81% average) is significantly slowing drying rates despite the season.
Contributing Factors
6
Over 23mm has fallen across at least 5 rain days in the past 7 days, with no meaningful dry window for internal drying between events.
Approximately 4mm of intermittent showers are falling today, re-wetting any surfaces that had begun to dry.
Average humidity of 81% over the past week severely limits evaporation rates even with wind assistance.
The south-facing, exposed hilltop setting with sustained winds (20–37 km/h recently) will accelerate drying once rain stops, but cannot compensate for ongoing precipitation.
An additional 1.9mm is forecast for June 10 and 5.7mm on June 11, extending the wet period and preventing any drying progress until at least June 12.
Temperatures around 13–14°C are adequate for evaporation but not high enough to drive rapid drying of deeply saturated sandstone.
Recommendations
3
- Do not climb at Shaftoe today or in the next two days — the rock is saturated from repeated rain and further showers are forecast through June 11.
- The earliest realistic window to assess conditions is the afternoon of June 13, after two full dry days with good wind and improving temperatures — but check individual boulders carefully before committing.
- On arrival, test ground conditions around the base of boulders: if the moorland turf is still damp, the rock interior is almost certainly too wet, even if surfaces appear dry.

Shaftoe Crags have received substantial rain over the past week (~27mm in 7 days) with the most recent rain falling today (4.5mm), meaning the porous Fell Sandstone is currently saturated and unsafe to climb. Although the afternoon looks dry and breezy, there has been nowhere near enough drying time since the last significant rainfall, and more rain is forecast for the coming days.
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 first, but sheltered caves, roofs, and north-facing faces (like the Neb Roof and Main Buttress) can remain damp for days or weeks longer.
- Active damage to classic problems from wet climbing is a known and ongoing concern at Shaftoe; the local community enforces a strict no-climbing-when-damp ethic.
- The exposed hilltop setting and south aspect are favourable for drying once dry weather arrives, but the recent multi-day rain sequence (June 1–4 totalling ~26mm plus further rain on June 6 and today) means internal moisture levels are high.
- Iron oxide deposits that form the small holds climbers rely on are especially vulnerable to grain loosening when the sandstone is internally saturated — even if surfaces feel dry later today, the interior will not be.
Warnings
2
- Climbing on wet Fell Sandstone causes permanent, irreversible damage to holds — classics at Shaftoe are already showing wear from bad-condition climbing.
- The rock surface may appear dry during this afternoon's breezy, lower-humidity window, but the interior will still be heavily saturated after repeated wetting — do not be deceived by surface appearance.
Reasoning
The rock has received approximately 27mm of rain in the past 7 days across multiple events (June 1–4, June 6, and today June 8), with rain falling as recently as this morning — the sandstone will be saturated well above the critical ~1% threshold where significant weakening begins.
There has been no meaningful dry spell since the prolonged wet period began on June 1; brief dry gaps of one day (June 5, June 7) with high humidity (71–76%) and moderate temperatures (~14–16°C) are wholly insufficient to dry porous sandstone after cumulative heavy rain.
With internal saturation likely high after repeated wetting events, compressive strength is reduced by an estimated 30%+ and holds — particularly the iron-oxide features — are at serious risk of breakage.
Early June should offer improving conditions, but this unsettled spell with cool temperatures (avg 12.3°C) and high humidity (avg 82%) is performing more like a prolonged autumn wet period, and freeze-thaw is not a concern at these temperatures.
Contributing Factors
6
Approximately 27mm has fallen in the past 7 days across multiple events, with the last rain today, keeping the sandstone repeatedly wetted and unable to begin meaningful drying.
4.5mm of rain fell this morning (mostly between 01:00–09:00), resetting any partial drying from yesterday's dry spell.
Average humidity over the past week is 82%, severely limiting evaporative drying potential even during dry hours.
The hilltop exposure and south-facing aspect will promote faster drying once a sustained dry spell arrives, with decent wind speeds (~20–30 km/h) helping move moist air away.
Rain is forecast for every day from June 9–13 (totalling ~10mm), preventing the 48–72+ hours of dry weather needed to begin safe climbing.
Temperatures averaging around 12–14°C are below the summer norm for effective drying, extending the time needed for internal moisture to evaporate.
Recommendations
3
- Do not climb at Shaftoe today or in the coming days — the rock is saturated after repeated recent rain and more is forecast.
- Monitor the forecast from June 14 onwards; you will need at least 48–72 hours of dry, breezy weather before conditions become viable.
- When conditions do improve, check individual boulders rather than assuming uniform dryness — south-facing exposed blocks will dry first, while caves, roofs, and sheltered faces will lag significantly.

Shaftoe has received over 27mm of rain in the last 7 days across multiple events (June 1–6), with the most recent precipitation today (0.1mm) and significant falls of 9.4mm and 6.2mm on June 3–4. Despite the exposed, south-facing aspect and good wind, the cumulative soaking combined with high humidity (85% average over the last week) means the porous Fell Sandstone will still be saturated internally and needs several dry days to recover.
Based on weather conditions only — does not cover bird nesting restrictions or other access issues.
- Scattered boulders dry at different rates — some exposed south-facing blocks may appear surface-dry while sheltered or north-facing sides remain saturated internally.
- Damage to classic problems from wet climbing is an active and documented concern at Shaftoe; the local community enforces a strict approach to conditions.
- The condition reports from March show that even after strong winds and sunshine, caves, roofs, and deep cracks (e.g. the Neb Roof) can remain damp for days or weeks after the open faces have dried.
- The exposed hilltop setting and strong westerly winds (25–35 km/h) will help surface drying, but with 27mm falling over a 6-day period, internal moisture will persist well beyond surface appearance.
Warnings
3
- Climbing on wet Fell Sandstone causes permanent, irreversible damage to holds — classics at Shaftoe are already showing wear from bad-conditions climbing.
- The rock surface may appear dry while the interior remains saturated; do not rely on visual or touch checks alone after this much rain — wait for the full drying period.
- Forecast rain every day through June 12 will repeatedly re-wet the rock, resetting any drying progress.
Reasoning
With 27.2mm of rain spread across six days (June 1–6) and today's trace precipitation, the rock has been repeatedly re-wetted and will be saturated internally despite any surface drying between showers.
Today is effectively the first potential drying day after the last significant rain (1.4mm on June 6), but with 80% humidity and only partial sun, meaningful drying has barely begun — the south-facing aspect and strong 35 km/h SW wind help surface evaporation but cannot overcome the cumulative internal moisture from nearly a week of rain.
The repeated wetting over six days will have the rock at or near its 80% strength-loss threshold; climbing now risks hold breakage and permanent damage to the soft Fell Sandstone, especially on the classic problems already showing wear.
Early June temperatures (12–18°C) are moderate and support drying when conditions allow, but the current unsettled spell with high humidity is limiting evaporation rates significantly.
Contributing Factors
6
Over 27mm of rain across six days (June 1–6) has repeatedly saturated the porous sandstone, preventing any meaningful drying between events.
Average humidity of 85% over the last 7 days severely limits evaporation rates, keeping internal moisture levels high.
Sustained winds of 25–35 km/h across the exposed hilltop will aid surface drying once rain stops, but cannot overcome the cumulative moisture deficit in one day.
The south-facing orientation maximises solar radiation for drying, though this advantage is reduced by the current overcast, humid conditions.
3.0mm forecast for tomorrow and further rain on each of the next four days means the rock will be repeatedly re-wetted with no opportunity for a sustained drying window.
Temperatures around 13–16°C are adequate for summer drying but not warm enough to rapidly drive off deep moisture from prolonged saturation.
Recommendations
3
- Do not climb at Shaftoe today or in the coming days — the rock is internally saturated and the forecast offers no adequate drying window until at least June 13.
- Monitor conditions for a sustained 48–72 hour dry spell with wind before visiting; surface-dry appearance alone is not sufficient after this level of soaking.
- When conditions do improve, check individual boulders carefully — exposed south-facing blocks will dry first, while caves, roofs, and cracks (e.g. the Neb Roof, Main Buttress) will take significantly longer.
Do Not Climb

Shaftoe Crags has received over 30mm of rain in the past week, including 4.7mm today, with high humidity averaging 84%. Despite the exposed south-facing aspect, the rock has had zero consecutive dry days and is almost certainly saturated internally — climbing today or in the immediate future risks permanent damage to this irreplaceable venue.
Based on weather conditions only — does not cover bird nesting restrictions or other access issues.
- Scattered boulders dry at different rates — some sheltered blocks, caves, and north-facing sides will hold moisture far longer than the most exposed south-facing walls.
- Recent condition reports confirm that even after extended dry spells, features like the Neb Roof and deep cracks retain dampness for days or weeks — these will be among the last to dry.
- The community has flagged active damage to classic problems from wet climbing; Shaftoe's ethics demand a strict approach and visible wear is already evident on popular lines.
- The exposed hilltop and strong winds are the site's best drying asset, but sustained high humidity (84–91%) in recent days severely limits net evaporation even with good airflow.
Warnings
2
- Climbing on wet Fell Sandstone causes irreversible hold breakage — classic problems at Shaftoe are already showing damage from poor-condition climbing.
- The rock surface may appear dry before the interior has dried; do not be deceived by superficial drying after short breaks in rain.
Reasoning
With 30.8mm of rain in the last 7 days including rain today (4.7mm), the rock is almost certainly saturated well beyond the critical 1% threshold where significant strength loss begins.
Despite the south-facing exposed aspect and moderate winds, zero consecutive dry days and persistently high humidity (84–91%) mean virtually no effective drying has occurred since the recent rain sequence began on June 1st.
At current saturation levels, Fell Sandstone will have lost 10–50% of its compressive strength; climbing risks hold breakage and accelerated erosion of the iron-oxide features that define the problems.
Early June should offer good drying potential, but this unsettled spell with cool temperatures (averaging 12.6°C) and high humidity is performing well below seasonal norms for drying.
Contributing Factors
6
Over 30mm in the past 7 days across multiple rain events (June 1–6), with 4.7mm falling today, means the rock has been repeatedly re-wetted with no chance to dry.
There have been no consecutive dry days since May 31st, giving the porous sandstone no drying window whatsoever.
Average humidity of 84% over the past week, peaking at 91% today, severely suppresses evaporation even with wind exposure.
Average temperatures of 12.6°C over the past week are below seasonal norms, slowing evaporative drying.
The open hilltop setting with south-facing aspect and strong winds (19–37 km/h) provides above-average drying potential once rain stops and humidity drops.
Rain is forecast on 4 of the next 5 days (totalling ~17mm), meaning the rock will continue to be re-wetted with no meaningful drying window.
Recommendations
3
- Do not climb at Shaftoe today — the rock is wet and structurally compromised; climbing will cause permanent damage to holds and routes.
- Monitor the forecast beyond June 11th; you will need at least 48–72 hours of dry, breezy weather with humidity below 75% before conditions become viable.
- When you do visit after a dry spell, test individual boulders by checking the ground at the base and feeling sheltered cracks — surface dryness does not guarantee internal dryness on these scattered blocks.
