AI-powered assessment using site data and 14-day weather history
Scout Crag has had light rain overnight and early this morning, with further scattered showers forecast through the afternoon and evening; although there is a potentially dry window mid-morning to early afternoon, high humidity and persistent cloud cover will limit drying on the south-facing rock. The week ahead looks unsettled with rain on most days, so conditions are unlikely to improve soon.
Based on weather conditions only — does not cover bird nesting restrictions or other access issues.
- Tree cover above the crag can cause persistent drips onto routes for hours after rain, even when the sky clears — check for seepage at the base of routes before committing.
- As a low-altitude valley crag at 150m, Scout Crag avoids cloud-base issues that plague higher Langdale venues, but the sheltered valley position can trap humidity and slow air movement.
- The south-facing aspect is a significant advantage for drying, but today's heavy cloud cover (near 100% all day) negates most solar benefit.
- Being roadside near the Old Dungeon Ghyll makes it easy to drive up, check conditions, and retreat without committing to a long walk-in — worth a look if passing.
Warnings
2
- BVS rhyolite becomes very slippery when damp — do not trust friction-dependent moves on wet or greasy rock.
- Intermittent showers are forecast through the afternoon and intensifying into the evening; conditions could deteriorate rapidly mid-route.
Reasoning
Light rain fell in the early hours (0.5mm between 03:00–06:00) and the previous days (May 3rd saw 10.3mm, with trace amounts since), so the rock surface is likely damp with residual moisture from overnight precipitation and high humidity.
Despite the south-facing aspect, near-total cloud cover all day eliminates meaningful solar drying, and humidity remains 69–88% through the afternoon — surface moisture from the light overnight rain will be slow to evaporate.
No structural risk — BVS rhyolite is non-porous and does not weaken when wet, so hold breakage is not a concern.
Early May in the Lake District is transitional with unpredictable weather; the recent warm dry spell (late April) has given way to a cooler, unsettled pattern more typical of spring.
Contributing Factors
6
Scattered light precipitation totalling ~2.3mm through today will keep rock surfaces intermittently damp.
Humidity stays above 69% throughout the day with near-total cloud cover, severely limiting evaporative drying.
The south-facing orientation would normally aid rapid drying, but 98–100% cloud cover today eliminates direct solar heating.
Rhyolite does not absorb water so there is no structural damage risk, and it will dry quickly once conditions improve.
Tree cover above the crag will cause persistent dripping onto routes well after rain stops, prolonging surface dampness.
A prolonged dry spell from April 21–30 means no deep saturation of the ground or persistent seepage issues from earlier heavy rain.
Recommendations
3
- If you are in the valley and keen, drive up to inspect the crag during the driest window (10:00–14:00) — some routes may have dried sufficiently, but be prepared to walk away.
- Consider waiting for a clearer forecast day; the next five days look unsettled with rain on most days, so patience will be needed.
- If you do climb, stick to well-drained, steeper lines that shed water quickly, and avoid any route with visible seepage or drips from the tree canopy above.

Scout Crag has had two dry days following 10.3mm of rain on May 3rd, with today dry and humidity dropping to the mid-40s this afternoon — the south-facing BVS rock should be largely dry on exposed faces. However, tree drips above the crag and a recent wet spell mean some dampness could linger in sheltered areas, so a visual check on arrival is prudent.
Based on weather conditions only — does not cover bird nesting restrictions or other access issues.
- Tree cover above the crag can channel persistent drips onto routes for hours after rain — check the tops of pitches for residual moisture even if the main face looks dry.
- The south-facing aspect and low altitude (150m) mean the crag gets good solar heating through the afternoon, making midday-to-late-afternoon the optimal drying and climbing window.
- Being a roadside valley crag, Scout Crag sits in a sheltered position that reduces wind-assisted drying compared to more exposed venues higher up Langdale.
- The recent prolonged wet spell (110mm in 28 days) may sustain seepage from saturated ground above the crag despite the rock itself being non-porous.
Warnings
1
- A prolonged wet and cool spell is forecast from May 8th–10th (36mm+ over three days); conditions will be unsuitable for several days after that front passes.
Reasoning
The last significant rain was 10.3mm on May 3rd, followed by two essentially dry days (0.0mm and 0.1mm) and a fully dry day today with humidity falling to 44–48% this afternoon — the exposed south-facing rock surface should be dry, though sheltered spots and areas beneath tree cover may retain dampness.
Two full dry days with the south-facing aspect receiving good May solar radiation, combined with moderate winds and falling humidity, provide adequate drying for a non-porous volcanic surface, though the sheltered valley position somewhat limits airflow.
BVS rhyolite is non-porous and does not suffer structural weakening from moisture — no hold breakage risk, but friction loss on damp patches remains the primary concern.
Early May in the Lake District brings reasonable daylight hours and warming temperatures, but the recent unsettled spell is typical of spring; conditions can deteriorate rapidly with the incoming frontal system forecast from May 7th onwards.
Contributing Factors
6
No significant rain since May 3rd (10.3mm), with May 4th and 5th essentially dry and today completely dry, allowing good surface drying on this non-porous rock.
Humidity drops to 44–48% through the afternoon today, aiding final evaporation of any residual surface moisture.
The south aspect at low altitude receives strong May sunshine when cloud breaks, accelerating surface drying significantly.
Tree cover above the crag can channel drips onto upper sections of routes well after rain has stopped, creating localised damp patches.
Over 110mm in the last 28 days means the ground above the crag is saturated, potentially feeding seepage lines despite the rock being non-porous.
Light rain forecast from May 7th escalating to heavy rain by May 9–10th means today is the last good window before a significant deterioration.
Recommendations
3
- Climb this afternoon (midday–5pm) when humidity is lowest and solar heating is strongest — this is likely the best window before rain returns tomorrow.
- Visually inspect routes before committing, particularly upper sections beneath tree cover where drips may persist.
- Carry a towel and avoid routes known for seepage lines; if any dampness is felt on the rock surface, back off — BVS friction vanishes when wet.

Scout Crag received 10.3mm of rain on May 3rd and today (May 5th) is seeing light showers through midday with heavier rain forecast from 17:00. While there was a full dry day yesterday (May 4th) with clearing skies in the afternoon that would have aided drying, the light rain earlier today and the 10.3mm from two days ago mean surface moisture is likely present. A brief window in the early-to-mid afternoon (13:00–16:00) may offer the driest conditions, but climbers should visually assess the rock before committing.
Based on weather conditions only — does not cover bird nesting restrictions or other access issues.
- Tree cover above the crag can cause persistent drips well after rain has stopped — check for overhead seepage even if the rock face appears dry.
- The south-facing aspect and low altitude (150m) in the sheltered Langdale valley mean the crag benefits from good solar heating during any sunny breaks, aiding rapid surface drying on this non-porous BVS rock.
- Being a roadside crag with minimal approach, climbers can easily drive up, check conditions, and retreat without committing to a long walk-in — making an 'assess on arrival' approach very practical here.
- Heavy cumulative rainfall over the past month (112.7mm) may sustain ground seepage and localised dampness on lower sections of the buttress despite the rock being non-porous.
Warnings
2
- Heavier rain (1.3mm) is forecast from 17:00 today — do not be caught on routes as conditions will deteriorate rapidly in the late afternoon.
- The high cumulative rainfall this spring means localised seepage is possible even on apparently dry sections — test friction before committing to harder moves.
Reasoning
The crag received 10.3mm on May 3rd, had a full dry day on May 4th with clearing afternoon skies (humidity dropping to 59%), but today has seen light drizzle (0.1–0.2mm) through midday with heavier rain (1.3mm) forecast at 17:00, so the rock surface is likely damp in places.
Yesterday's dry afternoon with moderate westerly wind and some sunshine would have dried surface moisture from the May 3rd rain on this south-facing non-porous rock, but today's overcast skies, light drizzle, and modest northerly wind are limiting further drying.
BVS rhyolite is non-porous and suffers no structural weakening when wet — there is no risk of hold breakage from moisture.
Early May in the Lake District brings lengthening days and reasonable solar angle for this south-facing crag, but spring weather remains unsettled with frequent frontal systems, as evidenced by the wet pattern over the past month.
Contributing Factors
7
10.3mm fell two days ago, contributing to residual dampness despite a dry intervening day.
Light drizzle through midday (0.1–0.2mm per hour) is re-wetting the rock surface, with heavier rain (1.3mm) forecast at 17:00.
May 4th was completely dry with clearing skies from mid-afternoon, humidity dropping to 59%, and moderate wind — good drying conditions for this non-porous rock.
The south-facing orientation maximises solar radiation even through broken cloud, aiding surface evaporation during any sunny breaks.
Tree cover above the crag causes persistent dripping after rain, which may still be active given rainfall 48 hours ago and today's drizzle.
112.7mm in the past 28 days indicates saturated ground above the crag, increasing the risk of seepage onto routes.
The period from roughly 13:00–16:00 is forecast dry with humidity around 53–59%, offering a potential climbing window if the rock has dried from morning drizzle.
Recommendations
3
- If visiting today, arrive early afternoon (13:00–15:00) to take advantage of the brief dry window before rain returns at 17:00, and visually check the rock and tree-drip areas before climbing.
- Tomorrow (May 6th) looks more promising with a fully dry forecast and lower humidity (57%) — consider waiting a day for more reliable conditions.
- Touch-test the rock surface carefully, particularly in any recesses or beneath overhanging sections where tree drip collects, as BVS friction degrades significantly when damp.

Yesterday's 10.3mm of rain on an already wet period means the rock surface may still carry residual moisture this morning, but a dry afternoon with clearing skies, dropping humidity (to ~55%), and a gentle westerly breeze should allow the south-facing BVS rock to dry adequately by early-to-mid afternoon. Climbers arriving after 14:00 should find good conditions but should visually confirm dryness on arrival.
Based on weather conditions only — does not cover bird nesting restrictions or other access issues.
- Tree cover above Scout Crag can cause persistent drips onto routes for hours after rain stops — check for localised seepage from the tree line before committing to climbs directly below vegetation.
- The crag's south-facing aspect and low valley position mean the afternoon sun break forecast from ~14:00 (cloud dropping to 30–35%) will significantly accelerate surface drying.
- The last 28 days have seen 110.5mm of rain — the surrounding ground and drainage above the crag will be saturated, increasing the risk of water running down from above even when the rock face itself appears dry.
- Scout Crag's roadside location in Great Langdale means no lengthy approach — climbers can easily drive up, assess conditions visually, and retreat without significant time loss if the rock is still damp.
Warnings
2
- The rock will be slippery this morning — do not climb before the afternoon drying window.
- Tree-line drips above the crag can persist for many hours after rain; check individual routes carefully for localised wetness.
Reasoning
10.3mm fell yesterday (May 3rd) with 100% cloud cover all day and high humidity (78–93%), meaning minimal drying occurred; the rock surface is likely still damp this morning.
Today's forecast shows clearing skies and humidity dropping to 54–56% by mid-afternoon with a light westerly wind (~13 km/h), giving the south-facing volcanic rock several hours of good drying conditions — surface moisture should evaporate by early-to-mid afternoon.
BVS rhyolite is non-porous and does not suffer structural weakening when wet, so there is no hold breakage risk — the concern is purely friction loss on damp surfaces.
Early May in the Lake District is a transitional period with lengthening days and reasonable solar angle; the 110.5mm over the past 28 days reflects a wet spring, but valley crags at 150m are well positioned to exploit any drying windows.
Contributing Factors
6
10.3mm fell on May 3rd under persistent cloud cover with high humidity, and the rock has had less than 24 hours to dry.
Cloud cover drops to ~30% by 15:00 with humidity falling to 54–56% and a moderate westerly breeze, providing strong drying conditions on this south-facing crag.
The 150m altitude and southerly aspect maximise solar input during the afternoon clearing, allowing rapid surface evaporation on the non-porous BVS rock.
110.5mm in the last 28 days has thoroughly saturated the hillside above, and tree-line drips and surface runoff may persist onto routes even after the rock face dries.
Overnight humidity remained at 88–89% with near-full cloud cover, preventing any meaningful drying before morning.
BVS rhyolite does not absorb water, so only surface moisture needs to evaporate — drying is relatively quick once conditions improve.
Recommendations
3
- Wait until mid-afternoon (after 14:00) to climb, when the clearing skies and dropping humidity will have given the south-facing rock several hours of good drying.
- Visually and physically check the rock surface on arrival — run a hand across key holds and look for dark wet patches, especially below the tree line above the crag.
- Avoid routes directly beneath overhanging vegetation or drainage lines, as tree-drip and hillside seepage may persist longer than the open rock face takes to dry.

Scout Crag received 10.2mm of rain today and is almost certainly wet right now. Although the south-facing BVS rock will dry relatively quickly, with high humidity (83%) and light northerly winds offering no direct sun-driven drying this afternoon, surface moisture is likely to persist into the evening.
Based on weather conditions only — does not cover bird nesting restrictions or other access issues.
- Tree cover above the crag is known to cause persistent drips after rain — today's 10mm will likely feed canopy drips well into tomorrow morning even if the rock face itself begins drying.
- The south-facing aspect is currently receiving a northerly wind, which means the crag face is somewhat sheltered from the breeze and drying will be slower than on a southerly-wind day.
- As a low-altitude valley crag beside the road, it avoids cloud-base and altitude penalties — once the rain stops and sun returns, it will dry faster than higher Langdale venues like Raven Crag or Pavey Ark.
- The preceding week (Apr 23–30) was exceptionally dry with warm temperatures, so ground saturation is moderate despite the recent wet spell — seepage from above should be limited.
Warnings
2
- The rock is currently wet and slippery — climbing today risks a friction-related fall on what are otherwise straightforward routes.
- Do not assume the crag is dry just because the road and valley floor appear dry; check the rock surface and any drip lines from the tree cover above.
Reasoning
With 10.2mm of rain today and 83% humidity, the rock surface is currently wet and unlikely to dry fully before end of day.
The northerly wind at 13 km/h offers only modest drying, and with the crag facing south, the wind does not sweep directly across the face; meaningful drying will require tomorrow's forecast dry weather and improved conditions.
BVS rhyolite is non-porous and does not suffer structural weakening when wet — there is no hold-breakage risk from climbing on damp rock, only friction loss.
Early May in the Lakes brings lengthening days and reasonable solar angles for a south-facing crag, but spring showers remain frequent and temperatures are modest, limiting evaporation rates.
Contributing Factors
7
Significant rainfall today means the rock surface is currently wet with standing moisture in cracks and on ledges.
Elevated humidity slows evaporation and keeps the rock surface damp for longer after rain.
The south-facing crag is sheltered from today's northerly wind, reducing the wind's drying effect on the climbing surface.
Tree cover above the crag will continue to shed drips for hours after rain ceases, prolonging surface wetness.
Rhyolite does not absorb water, so once surface moisture evaporates the rock returns to full friction quickly.
Valley-floor location avoids cloud immersion and benefits from warmer temperatures relative to higher crags.
An extended dry period from Apr 21–30 means the ground is not heavily saturated, limiting prolonged seepage from above.
Recommendations
3
- Wait until tomorrow (May 4th) when dry weather is forecast — the south-facing rock should dry well through the morning with lower humidity and westerly wind.
- If visiting tomorrow, check for residual drips from the tree canopy above the crag before committing to routes, especially in the upper sections.
- Consider arriving after midday tomorrow to give the south-facing aspect maximum sun exposure for drying.

Scout Crag received 9.5mm of rain today with high humidity (83%), and the rock will still be wet or damp this evening. Although the south-facing BVS rhyolite dries relatively quickly, today's rain combined with residual moisture from earlier in the week means surface conditions are currently unsuitable for safe climbing.
Based on weather conditions only — does not cover bird nesting restrictions or other access issues.
- Tree cover above the crag traps moisture and causes persistent drips onto routes even after rain stops, extending effective drying time beyond what the south-facing aspect alone would suggest.
- The crag sits at valley level beside the road, so approach is minimal — climbers can easily drive past to visually check conditions before committing.
- Being sheltered in Great Langdale valley, the crag benefits from warmth trapped in the valley but can also retain humid air on still days, slowing surface drying.
- The northerly wind today is less effective at drying this south-facing crag compared to the prevailing southwesterlies, as the crag face is somewhat sheltered from northerly airflow.
Warnings
1
- BVS rhyolite becomes dangerously slippery when wet — do not attempt to climb on damp rock as friction loss is severe.
Reasoning
The crag received 9.5mm of rain today on top of light showers on May 1st and 2nd, so the rock surface is currently wet with standing moisture in cracks and on ledges.
Today's northerly wind at 13 km/h provides limited drying benefit on this south-facing crag, and with 83% humidity and only moderate temperatures (12.7°C), meaningful drying will not occur until tomorrow's dry weather with westerly winds.
BVS rhyolite is non-porous and suffers no structural damage when wet — the only risk is friction loss on damp surfaces.
Early May in the Lakes brings improving daylight and temperatures, but the prolonged wet April (114mm in 28 days) means the surrounding ground and tree canopy are saturated, contributing to ambient moisture and drip lines.
Contributing Factors
7
Significant rainfall today means the rock surface is currently wet and will need several hours of dry weather to become climbable.
Elevated humidity today slows evaporation and keeps the rock surface damp longer than the temperature alone would suggest.
Today's northerly wind at 13 km/h is less effective at drying this south-facing buttress, as airflow does not impinge directly on the climbing face.
Overhanging vegetation above the crag will continue dripping onto routes well after the rain stops, prolonging surface dampness.
BVS rhyolite does not absorb water, so once surface moisture evaporates the rock will be immediately climbable with no internal drying period required.
The 150m altitude and south aspect mean it will benefit from solar heating tomorrow, promoting relatively fast drying once conditions improve.
A good run of dry days from April 21–30 helped reset baseline moisture, but the last three days have reintroduced dampness.
Recommendations
3
- Do not climb today — the rock is wet from 9.5mm of rain and tree drip lines will keep routes damp into the evening.
- Tomorrow (May 4th) looks promising with a dry forecast and westerly winds; drive past and visually inspect the crag before gearing up, paying particular attention to routes below tree cover.
- If routes below the tree canopy are still dripping tomorrow, consider the more open sections of the buttress which will dry first.

Scout Crag received 6.3mm of rain today with high humidity (83%), and the rock will still be wet or damp this afternoon/evening. Although the preceding week was largely dry and the rock is non-porous, today's rain combined with tree drip means surface moisture is likely present and friction will be compromised.
Based on weather conditions only — does not cover bird nesting restrictions or other access issues.
- Tree cover above the crag causes persistent drips well after rain has stopped — today's 6.3mm will likely produce lingering drips into the evening and possibly tomorrow morning.
- The south-facing aspect is helpful for drying, but with a northerly wind today the crag is somewhat sheltered from direct wind exposure, slowing surface evaporation.
- The crag sits low in Great Langdale valley where cool, moist air can pool, and the 83% humidity today will further retard drying.
- The preceding dry spell (April 21–30) will have thoroughly dried out the hillside above, so seepage risk from saturated ground is low — today's moisture is primarily surface-level.
Warnings
2
- Rock will be slippery today — BVS rhyolite loses friction dramatically when wet, creating a serious slip/fall hazard.
- Tree drip above the crag may persist for many hours after rain stops; do not assume the rock is dry just because it has stopped raining.
Reasoning
Today's 6.3mm of rain on top of yesterday's light 0.2mm and 2.1mm on May 1st means the rock surface is currently wet, with tree drip overhead likely prolonging dampness.
The south-facing aspect would normally promote quick drying, but today's northerly wind direction means the crag face is somewhat sheltered, and the high humidity (83%) limits evaporative drying — several hours of dry weather with sun will be needed.
No structural risk — BVS rhyolite is non-porous and does not weaken when wet; the concern is purely friction loss on damp surfaces.
Early May in the Lakes offers reasonable daylight and warmth, but spring weather remains unsettled; temperatures around 12°C with high humidity are marginal for rapid drying.
Contributing Factors
7
Significant rainfall today means the rock surface is currently wet and friction is severely reduced.
Ambient humidity of 83% with northerly wind significantly slows evaporation from the rock surface.
Tree cover above the crag is known to cause persistent dripping well after rain ceases, prolonging surface dampness.
Rhyolite does not absorb water, so once surface moisture evaporates, the rock will be fully dry with no internal dampness.
The south aspect and 150m altitude favour relatively quick drying once rain stops and sun reaches the face.
Five consecutive dry days (April 26–30) before this week's light rain means the hillside is not saturated, reducing seepage risk.
A north wind offers little direct airflow across the south-facing crag, reducing wind-assisted drying.
Recommendations
3
- Do not climb today — the crag will be wet from this morning's rain with tree drip prolonging dampness.
- Tomorrow (May 4th) looks promising with a dry forecast and SW wind; arrive after midday to allow morning sun and breeze to dry the face.
- Check for persistent drips from the tree line above before committing to routes, especially on the upper sections of the buttress.

Scout Crag enjoyed an excellent drying spell from April 21–30 but has received light rain on May 1 (2.1mm) and today (1.2mm), with humidity now at 83%. The south-facing BVS rock should shed this light moisture quickly in any afternoon sun, but surface dampness — particularly from tree drip — is possible and should be checked on arrival.
Based on weather conditions only — does not cover bird nesting restrictions or other access issues.
- Tree cover above the crag can cause persistent drips well after rain has stopped, so even after light showers the upper sections and crack lines may remain damp.
- The extended dry spell from April 21–30 (10 days, near-zero precipitation, humidity dropping to 45–55%) will have thoroughly dried out any deep seepage from the heavy mid-April rains, meaning residual sub-surface moisture is unlikely.
- As a low-altitude valley crag with a south-facing aspect, Scout Crag benefits from direct solar radiation through the afternoon — even a few hours of sunshine today could dry the light surface moisture from this morning's 1.2mm.
- Being roadside near the Old Dungeon Ghyll allows for easy visual inspection and a quick retreat if conditions aren't right — there's no long walk-in commitment.
Warnings
1
- Tree drip above the crag may keep specific routes or sections damp even when the main face appears dry — test friction before committing to harder moves.
Reasoning
Today's 1.2mm of rain on top of yesterday's 2.1mm means the rock surface is likely damp this morning, though the total accumulation is very light and the preceding 8-day dry spell leaves no deeper moisture concerns.
The south-facing aspect at 150m with moderate wind exposure (15.8 km/h SW) should allow surface drying within a few hours if any sun breaks through, though 83% humidity will slow evaporation compared to the excellent conditions seen last week.
BVS rhyolite is non-porous and extremely hard — there is zero structural risk from this or any amount of moisture; the only concern is friction loss on damp surfaces.
Late April/early May is a transitional period in the Lakes with lengthening days and improving solar angle, but the current spell is cooler and more humid than the unusually warm conditions of the past week; bird nesting restrictions should be checked on BMC RAD.
Contributing Factors
6
Light rain today (1.2mm) and yesterday (2.1mm) will have wetted the rock surface, though volumes are small enough to dry quickly on non-porous rock.
An 8-day virtually dry spell (April 21–30) with warm temps up to 20.8°C and low humidity (45–55%) will have eliminated any residual moisture from the heavy mid-April rains.
Today's humidity at 83% will slow surface evaporation and may keep the rock feeling damp even where not directly wetted.
The south-facing aspect at just 150m receives strong solar radiation and warmth from the valley floor, enabling rapid drying of surface moisture.
Tree cover above the crag is known to cause persistent drips after any rain, which could keep specific sections damp well after the main surfaces have dried.
Partial wind exposure with 15.8 km/h SW winds provides useful airflow across the south-facing rock to aid surface drying.
Recommendations
3
- Visit in the afternoon to allow morning moisture and tree drip to dry off — a few hours of sun on this south-facing crag will make a significant difference.
- Inspect the rock surface carefully on arrival, particularly beneath any overhanging trees and in crack lines where drip moisture lingers.
- Check BMC RAD for any bird nesting restrictions at Scout Crag before visiting, as peregrine and raven closures are active across the Lakes through June.

Scout Crag has had an excellent drying window over the past 9+ days with negligible precipitation, warm temperatures up to 20°C, low humidity, and a favourable south-facing aspect. Today's 1.2mm is trivial on non-porous rock and will evaporate quickly in the mild, breezy conditions — the crag should be climbable this afternoon.
Based on weather conditions only — does not cover bird nesting restrictions or other access issues.
- Tree cover above the crag can cause persistent drips even after light rain — check the upper sections and any routes directly below tree canopy for residual drips from today's 1.2mm.
- The prolonged dry spell from April 21–30 (essentially zero rain for 10 days with temps reaching 20°C) means any deeper seepage from the earlier wet April period has had ample time to drain.
- South-facing aspect at low altitude in the valley means the crag receives strong spring sunshine through the day, maximising evaporation of today's trace rainfall.
- Being a roadside valley crag, conditions can be quickly assessed on arrival without a long walk-in — worth a visual check of the rock surface before committing.
Warnings
1
- Heavier rain (15.8mm) is forecast for May 3rd — conditions will deteriorate significantly from Saturday onwards.
Reasoning
After 9 consecutive virtually dry days (April 21–30) with only trace precipitation and warm temperatures, the rock surface was thoroughly dry before today's minor 1.2mm; this trace amount on non-porous BVS rhyolite will evaporate within hours.
The south-facing aspect with partial wind exposure, combined with temperatures reaching 18–20°C and humidity dropping to 45–55% over the past week, provided excellent drying conditions that far exceed what's needed for this non-porous volcanic rock.
BVS rhyolite is non-porous and extremely hard — there is no structural risk from moisture; the only concern is surface friction, which is not an issue given the extended dry period.
Early May in the Lakes offers lengthening days and improving sun angles; the south-facing aspect benefits from strong spring solar radiation, and temperatures are solidly above freezing with no frost risk at this altitude.
Contributing Factors
6
From April 21 to April 30, the crag received essentially zero precipitation over 10 days, thoroughly drying any residual moisture from the wet mid-April period.
Today's 1.2mm is very light and will evaporate quickly on sun-warmed non-porous rock, but technically breaks the dry streak and may leave minor surface dampness this morning.
Temperatures reached 19–21°C over the past few days with humidity as low as 45–50%, providing exceptional drying conditions for this time of year.
The south-facing orientation maximises solar exposure through the day, accelerating evaporation of any surface moisture.
Trees above the crag can hold moisture and drip onto routes after even light rain, potentially keeping localised areas damp longer than the open rock face.
Humidity today is 66% and forecast to rise to 84% tomorrow, which is manageable but suggests the current dry window is closing.
Recommendations
3
- Climb this afternoon for best conditions — allow any residual surface moisture from today's 1.2mm to evaporate in the morning sun.
- Check routes beneath tree cover for drips before committing, especially on the upper sections of the crag.
- Make the most of today and tomorrow — heavier rain is forecast for May 3rd (15.8mm), so this is the last reliable window for several days.

Scout Crag is in excellent condition today. The south-facing BVS rock has had a sustained dry spell since the last significant rain on April 20 (2.2mm), with nearly nine consecutive dry days, warm temperatures up to 19.5°C, and humidity dropping to the low 50s — the rock surface will be thoroughly dry and offering superb friction.
Based on weather conditions only — does not cover bird nesting restrictions or other access issues.
- Tree cover above the crag can cause localised drips even days after heavy rain, but after 9 essentially dry days this should not be an issue today.
- The south-facing aspect at low altitude in the Langdale valley has benefited from strong April sunshine and drying winds, making this one of the quickest-drying venues in the area.
- The crag sits just above the valley road near the Old Dungeon Ghyll — convenient access means you can quickly assess conditions on arrival if there's any doubt about sheltered corners.
- April's cumulative rainfall of ~149mm means the surrounding hillside is saturated; any seepage lines fed by ground-water from above could still be active on isolated sections of the crag.
Reasoning
With only 0.2mm of precipitation in the last 7 days (trace amounts on April 26–27) and today's humidity at 56%, the rock surface is dry and friction should be excellent.
The south-facing aspect, moderate wind exposure, and a run of warm sunny days (19.5°C on Apr 24–25) have provided ample drying since the last meaningful rain on April 20; even tree-drip zones will have dried out.
BVS rhyolite is non-porous and extremely hard — there is no structural risk from recent wet weather; hold integrity is not a concern.
Late April conditions are favourable with lengthening days providing good solar heating; however, check BMC RAD for any nesting restrictions as peregrine season runs through June.
Contributing Factors
6
Essentially nine dry days since the last meaningful rain on April 20, with only trace precipitation (0.1mm) on April 26–27.
Current humidity of 56% and a weekly average of 60% indicate dry air that promotes rapid surface evaporation.
Temperatures reaching 16–19°C over recent days with south-facing solar exposure have thoroughly dried the rock.
The 150m south-facing aspect maximises solar gain in spring, giving Scout Crag above-average drying speed compared to higher or north-facing venues.
Trees above the crag can cause persistent drips after rain, but the extended dry period means this is not a concern today.
Nearly 150mm fell in the preceding 28 days saturating the surrounding ground, but the non-porous rock itself is unaffected and has had ample time to dry.
Recommendations

- Conditions are excellent — enjoy the rough BVS friction; this is one of the best spells for climbing this month.
- Check BMC RAD for any seasonal bird nesting restrictions before climbing, as peregrine restrictions can apply through June.
- Minimise chalk use and brush holds after your session to maintain the rock and uphold local ethics.
