Condition Analysis
AI-powered assessment using site data and 14-day weather history
Quayfoot Buttress has had a few days of light, scattered precipitation following a heavier spell on May 3rd, and today is mostly dry with only trace amounts forecast from mid-afternoon. The south-facing BVS rock should be largely dry through the late morning window, but persistent cloud cover, moderate humidity, and the sheltered position mean a visual check on arrival is essential before committing to climb.
Based on weather conditions only — does not cover bird nesting restrictions or other access issues.
- Tree canopy above the upper left section can hold and drip moisture long after rain has stopped — avoid these routes if any recent precipitation has occurred.
- The sheltered Borrowdale valley position reduces wind-assisted drying, so even trace precipitation (0.5–0.6 mm over recent days) can leave damp patches lingering on shaded holds.
- Brown Slabs' delicate friction-dependent slab climbing is particularly sensitive to residual surface moisture — even a thin film dramatically reduces grip on these low-angle routes.
- The crag's roadside location means quick access and easy retreat if conditions turn; no lengthy walk-in commitment required.
Warnings
2
- Light drizzle is forecast from mid-afternoon onward — be prepared to retreat if surfaces become slick.
- The friction-dependent slab routes at Brown Slabs are disproportionately dangerous when damp; even a thin moisture film can cause unexpected slips on low-angle rock.
Reasoning
Light scattered precipitation over the past four days (0.6 mm on May 5, 0.5 mm on May 6, and 0.6 mm today) following 7.9 mm on May 3rd means the rock has not had a sustained dry spell, though individual amounts are small and the non-porous BVS surface sheds water readily.
The south/south-west aspect provides good solar exposure, but today's high cloud cover (73–100% from late morning) and the sheltered valley position limit both radiative and convective drying; the ~21 km/h southerly wind helps somewhat but is partially blocked by the valley.
Non-porous Borrowdale Volcanic rhyolite does not absorb water or suffer structural weakening — there is no risk of hold breakage from moisture, only friction loss on wet surfaces.
Early May in the Lake District brings lengthening days and reasonable temperatures (~10–11°C), but spring showers remain frequent and humidity averaging 76% over the past week keeps ambient moisture elevated.
Contributing Factors
6
Trace rainfall on May 5, 6, and today (0.5–0.6 mm each) means the rock has not had a clean multi-day dry spell since the 7.9 mm on May 3rd.
The S/SW aspect maximises solar exposure and the non-porous BVS rock sheds surface water efficiently, allowing rapid drying even from light showers.
The sheltered Borrowdale setting reduces airflow across the crag face, slowing evaporative drying compared to exposed venues.
Cloud cover is forecast at 73–100% through much of the day, limiting direct solar radiation that would otherwise accelerate drying on this south-facing crag.
Humidity around 67–77% through the middle of the day is above ideal for rapid surface drying and may allow condensation in sheltered spots.
No precipitation is forecast between 00:00 and 14:00, giving a potential climbing window through late morning before trace drizzle begins around 15:00.
Recommendations
3
- Target the late morning to early afternoon window (10:00–14:00) for the best chance of dry rock before light drizzle arrives around 15:00.
- Visually inspect holds and test friction on a lower route before committing — if Brown Slabs feel greasy, conditions are not adequate for the delicate slab climbing.
- Avoid the upper left section beneath the tree canopy, where drips may persist from overnight and early morning moisture.

Quayfoot Buttress has had roughly 1.5 dry days since the last light rain (0.6mm on May 5th) and a more significant shower (7.9mm on May 3rd), with today forecast completely dry at low humidity — the south-facing, non-porous BVS rock should be largely dry by mid-morning, but the sheltered position and tree canopy drips warrant a visual check on arrival. A deteriorating forecast from tomorrow onwards means today offers the best climbing window for the coming week.
Based on weather conditions only — does not cover bird nesting restrictions or other access issues.
- Tree canopy above the upper left section can hold and drip moisture onto routes long after rain has stopped — check this area carefully even when the main buttress feels dry.
- The sheltered Borrowdale valley position reduces wind-assisted drying despite the favourable south-facing aspect, so surface moisture can linger in shaded nooks.
- Brown Slabs and other friction-dependent slab routes here demand genuinely dry rock — even a thin film of moisture on BVS slab climbing dramatically reduces grip.
- Roadside access means quick retreat is easy if conditions aren't right; no long walk-in commitment required.
Warnings
1
- A prolonged wet spell is forecast from May 8th–10th with nearly 50mm of rain; plan accordingly if you miss today's window.
Reasoning
The last significant rain was 7.9mm on May 3rd, followed by a dry day (May 4th), trace rain on May 5th (0.6mm), and a fully dry day today — non-porous BVS rock at this south-facing, low-altitude crag should have surface-dried, though sheltered pockets and tree-drip zones may retain dampness.
Two mostly dry days with south-facing aspect and dropping humidity (down to 45% this afternoon) provide reasonable drying, though light winds (6–8 km/h) and the sheltered valley position limit convective drying compared to exposed crags.
No structural risk — Borrowdale Volcanic 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 lengthening days and reasonable solar angles for a south-facing crag, though temperatures remain cool (10°C max today) which slows evaporation slightly.
Contributing Factors
6
Only 0.6mm fell on May 5th and the crag has had a full dry day since, with today also completely dry — a trivial amount that should have evaporated from non-porous rock.
A moderate shower three days ago could have left residual dampness in sheltered or tree-canopy areas despite two subsequent drying days.
The S/SW aspect maximises solar heating through the day, promoting rapid surface evaporation on the main face.
Limited wind exposure slows convective drying, meaning sheltered corners and overhangs may stay damp longer than expected.
Humidity drops to around 45% through the afternoon today, strongly favouring evaporation and good friction conditions.
Heavy rain is forecast from May 8th–10th (totalling ~47mm), making today and possibly early tomorrow the only viable climbing window for the next week.
Recommendations
3
- Climb this afternoon when humidity is lowest (45%) and the south face has had maximum sun exposure — the window between 11:00 and 17:00 is optimal.
- Visually and physically check the rock surface for dampness before committing, especially on the upper left section beneath tree canopy where drips persist.
- Avoid Brown Slabs if any surface moisture is detected — friction-dependent slab climbing on BVS rock is unforgiving when damp.

Quayfoot Buttress has had a mostly dry spell since the 7.9mm rain on May 3rd, with yesterday (May 4th) completely dry and sunny in the afternoon. However, today sees light showers forecast from late afternoon, and the preceding wet period (nearly 92mm in 28 days) combined with sheltered position and high overnight humidity means some residual dampness is possible — a visual check on arrival is sensible.
Based on weather conditions only — does not cover bird nesting restrictions or other access issues.
- The tree canopy above the upper left section can cause persistent drips for hours after rain, even when the main face appears dry — check this area carefully after the May 3rd rain and any overnight moisture.
- South-facing aspect and roadside accessibility mean mid-morning to mid-afternoon offers the best drying window today before the forecast light showers arrive around 16:00.
- Borrowdale's sheltered valley position traps humidity overnight (91% early this morning), which can leave condensation on rock surfaces that takes an hour or two of sun or breeze to clear.
- The Brown Slabs area relies heavily on friction — even a thin film of moisture dramatically reduces grip on these delicate slab routes, so surfaces must be genuinely dry before committing.
Warnings
1
- Light showers are forecast from approximately 16:00 today — plan to finish climbing before then as the slabs will become slippery almost immediately.
Reasoning
The last significant rain was 7.9mm on May 3rd, followed by a full dry day yesterday with clearing skies in the afternoon; the non-porous rhyolite surface should be largely dry, though overnight humidity above 85% may have left condensation.
Yesterday's afternoon clearing (humidity dropping to 59%, light westerly breeze) provided several good drying hours, and today's midday humidity is forecast to drop to ~55% — sufficient to evaporate surface moisture on this south-facing crag, though the sheltered position limits wind-assisted drying.
No structural risk — Borrowdale Volcanic rhyolite is non-porous and does not weaken when wet; the concern is purely friction loss on damp surfaces.
Early May in the Lake District brings lengthening days and reasonable solar angles for this south-facing crag, but spring weather remains changeable with frequent frontal systems — the recent 28-day total of 92mm reflects typical Lake District spring conditions.
Contributing Factors
7
The 7.9mm on May 3rd was followed by a fully dry May 4th with afternoon sun and dropping humidity, giving over 24 hours of drying on non-porous rock.
Light showers totalling ~0.8mm are forecast from around 16:00 onwards, narrowing the usable climbing window to the morning and early afternoon.
The S/SW aspect maximises solar gain through the middle of the day, accelerating evaporation of any residual surface moisture.
The sheltered Borrowdale setting limits airflow across the crag, slowing wind-assisted drying and allowing overnight humidity to remain high.
Humidity exceeded 85% overnight and into early morning, potentially depositing condensation on rock surfaces that requires a couple of hours to clear.
Nearly 92mm in 28 days is substantial but largely irrelevant for non-porous rock — the key factor is hours since last wetting, not cumulative saturation.
Cloud cover is forecast at 95–100% for much of today, reducing direct solar heating that would otherwise accelerate drying on this south-facing crag.
Recommendations
3
- Aim for a late-morning to early-afternoon window (roughly 11:00–15:00) when humidity is lowest and before the forecast light showers arrive around 16:00.
- Touch-test the rock on arrival, particularly the Brown Slabs and the upper left section beneath the tree canopy, which can harbour drips long after rain.
- If surfaces feel at all greasy or damp, wait — the friction-dependent slab climbing here becomes significantly more hazardous with even a thin moisture film.

Yesterday saw 7.9mm of rain through the morning in saturated, overcast conditions (90% humidity), but rain stopped by mid-morning and today is forecast dry with clearing skies and dropping humidity through the afternoon. The south-facing, non-porous BVS rock at Quayfoot should be surface-dry by early afternoon, but the sheltered position and high overnight humidity mean a visual check on arrival is prudent.
Based on weather conditions only — does not cover bird nesting restrictions or other access issues.
- Tree canopy above the upper left section may still be dripping from yesterday's rain, as leaf-drip can persist for 12–24 hours in sheltered, humid conditions.
- Quayfoot's roadside position at the valley floor means it sits in the Borrowdale 'humidity bowl' — overnight dew and valley mist can re-wet surfaces even after a dry day.
- The Brown Slabs area relies heavily on friction on low-angle rock, so even a thin residual moisture film that wouldn't matter on steep routes becomes a real safety concern here.
- South/SW aspect means the crag should receive direct sun from late morning onwards today as cloud breaks, significantly accelerating surface drying.
Warnings
1
- Slab routes at Quayfoot are extremely friction-dependent; even a thin moisture film that is hard to see can cause a dangerous slip on low-angle rock.
Reasoning
7.9mm fell yesterday mostly before 10am, followed by overcast but dry conditions for ~18 hours; overnight humidity remained high (87–94%), so residual surface moisture and condensation are likely present this morning.
The south-facing aspect will catch sun as cloud cover drops below 60% from around 2pm today, and with humidity falling to 57% and light NW winds, exposed surfaces should be dry by early-to-mid afternoon — but the sheltered valley position slows air movement across the rock.
Non-porous Borrowdale Volcanic rhyolite does not absorb water and is not at risk of structural damage; the concern is purely friction loss on wet or damp surfaces.
Early May in the Lakes brings lengthening days and reasonable solar angles for a south-facing crag, though spring showers remain frequent and overnight temperatures near freezing can produce heavy dew.
Contributing Factors
6
Significant rainfall through yesterday morning in very humid conditions means surfaces were thoroughly wetted less than 24 hours ago.
No precipitation forecast today, with cloud cover dropping below 30% by mid-afternoon and humidity falling to 57%, creating good drying conditions from early afternoon.
The S/SW aspect will receive direct sun from late morning as cloud breaks, and non-porous BVS rhyolite sheds surface water quickly without internal absorption.
The sheltered Borrowdale valley floor limits air circulation across the crag, slowing evaporation and trapping overnight humidity.
Very high overnight humidity likely caused condensation or dew on rock surfaces, effectively re-wetting them even after yesterday afternoon's partial drying.
Brown Slabs and other low-angle routes at Quayfoot demand excellent friction, meaning even marginal dampness is a significant safety concern.
Recommendations
3
- Wait until early-to-mid afternoon (after 1–2pm) to allow sun and dropping humidity to dry surfaces fully before climbing.
- Physically touch the rock — especially the Brown Slabs and any shaded or tree-covered sections — to confirm it is genuinely dry and friction feels reliable before committing to routes.
- Avoid the upper-left section beneath the tree canopy, which is prone to persistent dripping after rain.

Quayfoot Buttress received 7.8mm of rain today with high humidity (88%) and a north-easterly wind that won't aid drying on the south-facing rock. Although the BVS rhyolite is non-porous and dries quickly, the sheltered valley position and tree canopy mean residual surface moisture is likely this evening, and conditions are not trustworthy for climbing today.
Based on weather conditions only — does not cover bird nesting restrictions or other access issues.
- The tree canopy above the upper left section will drip for hours after today's rain, keeping that area damp well after the open faces have dried.
- The sheltered Borrowdale valley position limits airflow despite the crag's excellent south-facing aspect, meaning today's moderate NE wind won't effectively reach the rock surface.
- Brown Slabs and other delicate slab routes demand excellent friction — even a thin film of residual moisture on BVS rhyolite can make these unacceptably slippery.
- The crag is roadside with minimal approach, so climbers can easily check conditions in person tomorrow morning without committing to a long walk-in.
Warnings
1
- Do not attempt the slab routes (Brown Slabs area) if any dampness is visible — even a slight film of moisture on BVS rhyolite dramatically reduces friction on low-angle climbing.
Reasoning
With 7.8mm of rain today and 88% humidity, the rock surface is almost certainly still wet or at least damp across much of the crag.
The NE wind direction is unfavourable for this S/SW-facing sheltered crag, and limited afternoon sun combined with high humidity means effective drying will be slow today — likely requiring a dry morning tomorrow to fully clear surface moisture.
No structural risk — BVS rhyolite is non-porous and does not suffer hold weakening or damage when wet.
Early May in the Lakes offers reasonable temperatures and daylight hours, but the recent unsettled spell (95mm in 28 days) means background moisture levels in the valley and tree canopy are elevated.
Contributing Factors
8
Nearly 8mm of precipitation today means the rock is currently wet and has had minimal drying time.
Very high humidity today significantly slows surface evaporation even on non-porous rock.
The NE wind won't reach this sheltered S/SW-facing crag effectively, reducing any wind-assisted drying.
The south-facing aspect normally provides excellent solar drying, though today's conditions limit its benefit.
The volcanic rock does not absorb moisture, so once surface water evaporates the rock will be fully dry with no internal dampness concerns.
The sheltered position in Borrowdale reduces air circulation and slows drying compared to exposed crags.
Overhanging trees above the upper left section will continue to drip for hours after rain ceases, prolonging dampness on those routes.
Tomorrow is forecast completely dry with lower humidity (75%) and moderate NW winds, suggesting good drying overnight and into the morning.
Recommendations
3
- Wait until tomorrow (May 4th) — the dry forecast with dropping humidity and south-facing sunshine should have the main faces climbable by mid-morning.
- If visiting tomorrow, check the upper left section beneath the tree canopy last, as drips from foliage can persist longer than the open rock faces.
- Given the minimal approach to this roadside crag, a quick visual and touch inspection before gearing up is easy and strongly recommended.

Quayfoot Buttress received 6.9mm of rain today with high humidity (89%) and a NE wind that won't help a south-facing crag dry. While the non-porous BVS rock can dry quickly, the sheltered position, tree canopy drips, and current damp conditions mean the rock is likely still wet or greasy this evening.
Based on weather conditions only — does not cover bird nesting restrictions or other access issues.
- The tree canopy above the upper left section will cause persistent drips well after rain stops, potentially lasting into tomorrow morning given today's 6.9mm.
- The sheltered Borrowdale valley position, while pleasant in bad weather, significantly slows air movement across the rock face and extends surface drying time.
- Today's NE wind direction is unfavourable for a S/SW-facing crag — the buttress is lee-side and receives minimal wind-assisted drying.
- The preceding dry spell (April 21–30) means the surrounding ground and rock mass are not saturated, so once the current rain clears, drying should be relatively swift.
Warnings
2
- Rhyolite friction drops dramatically when wet — do not rely on friction-dependent slab moves (e.g. Brown Slabs) until the rock is fully dry.
- Tree canopy drips on the upper left section can persist for many hours after rain and may not be obvious from below.
Reasoning
With 6.9mm falling today at 89% humidity and the crag sheltered from the NE wind, the rock surface is almost certainly wet or at least greasy right now.
The NE wind offers no drying benefit to this S/SW-facing sheltered crag; however, once the rain stops and conditions shift to tomorrow's westerly airflow with lower humidity (76%), the south-facing aspect should allow reasonable drying within a few hours of morning sun.
Borrowdale Volcanic rhyolite is non-porous and suffers no structural damage from moisture — the concern is purely friction loss on wet or greasy surfaces.
Early May in the Lakes offers reasonable daylight hours and moderate temperatures, but the recent cool spell (highs only 11°C today) slows evaporation compared to summer conditions.
Contributing Factors
7
6.9mm of rain today means the rock surface is currently wet, and the sheltered position will slow runoff and evaporation.
At 89% humidity, evaporative drying is significantly impaired and the rock will stay damp longer than usual.
The NE wind puts this S/SW-facing crag in a lee position, reducing wind-assisted drying to near zero.
BVS rhyolite does not absorb water, so once surface moisture evaporates the rock will climb well — no extended internal drying needed.
The S/SW aspect will receive good solar radiation tomorrow, promoting rapid surface drying once the rain clears and sun breaks through.
A sustained dry period from April 21–30 means the rock mass and surrounding ground are not deeply saturated, reducing seepage risk.
The tree canopy above the upper left section will continue dripping onto routes well after the rain stops, particularly after a 6.9mm event.
Recommendations
3
- Wait until tomorrow afternoon — the westerly wind and south-facing sun should dry the rock within a few hours of morning sunshine.
- Avoid the upper left section near the tree canopy first; the Brown Slabs area, being more open, will dry faster.
- Touch-test the rock before committing to any route — BVS rhyolite is notoriously slippery when even slightly damp despite its excellent dry friction.

Quayfoot Buttress received 5.4mm of rain today with very high humidity (89%) and light NE winds, meaning the sheltered south-facing rock will not have had meaningful drying time. While the non-porous BVS rock dries quickly, the combination of today's rain, high humidity, and sheltered position with NE airflow means surface moisture is very likely still present.
Based on weather conditions only — does not cover bird nesting restrictions or other access issues.
- The tree canopy above the upper left section will cause persistent drips well after rain stops, potentially keeping that area damp for many hours after the main rock face has dried.
- The sheltered Borrowdale valley position, while usually beneficial for warmth, today works against drying — the light NE wind at 12 km/h provides minimal airflow across the south-facing rock.
- South/SW aspect normally catches excellent sun, but with 89% humidity today, evaporative drying will be significantly impaired even if sunshine breaks through.
- The Brown Slabs area relies heavily on friction for delicate slab climbing — even a thin film of residual moisture makes these routes disproportionately dangerous compared to steeper featured routes.
Warnings
2
- The rock is almost certainly wet or damp right now — slab climbing on wet BVS rock is a serious slip hazard.
- Do not rely on the crag's reputation as a quick dryer; today's high humidity and poor airflow mean drying will be much slower than usual.
Reasoning
With 5.4mm of rain today and 89% humidity, the rock surface is almost certainly still wet or damp, particularly in sheltered spots and under the tree canopy.
Light NE winds at only 12 km/h on a south-facing sheltered crag provide poor drying conditions; the air is nearly saturated and the wind direction does not favour this aspect, so meaningful surface drying is unlikely to have occurred.
BVS rhyolite is non-porous and suffers no structural weakening when wet — the risk here is entirely friction loss and climber safety, not rock damage.
Early May in the Lakes is a transitional period with variable weather; the recent wet spell (92.6mm in 28 days) means the surrounding ground and vegetation are saturated, contributing to local humidity and slow ambient drying.
Contributing Factors
6
Significant rainfall today means the rock is currently wet or very recently wetted with zero consecutive dry days.
Near-saturated air severely inhibits evaporative drying even on non-porous rock.
A 12 km/h NE wind provides minimal drying benefit to this south/SW-facing sheltered crag.
Rhyolite does not absorb water, so once surface moisture evaporates the rock will be climbable — but that evaporation has not yet occurred.
Any sunshine that breaks through will warm the rock face directly, aiding surface drying, but today's conditions limit this advantage.
The sheltered position below the road and in the Borrowdale valley traps moist air and reduces wind-assisted drying.
Recommendations
3
- Wait until tomorrow (May 4th) when dry weather, lower humidity, and a westerly breeze should allow the rock to dry — arrive after midday for best conditions.
- If visiting today, do not commit to climbing the Brown Slabs or any slab routes, as these are friction-dependent and extremely dangerous when damp.
- Avoid the upper left section beneath the tree canopy, which will hold drips longest after any rainfall.

Quayfoot Buttress had an excellent dry spell from April 21–30, but light rain today (1.3mm) combined with high humidity (84%) means the rock surface may still be damp. Given the south-facing aspect and non-porous BVS rock, a brief dry spell could see it climbable later today, but on-site assessment is essential.
Based on weather conditions only — does not cover bird nesting restrictions or other access issues.
- The tree canopy above the upper left section will cause persistent drips even hours after rain stops — avoid those lines first and focus on the open Brown Slabs area.
- Quayfoot's sheltered valley position means wind-assisted drying is minimal despite being one of the quickest-drying crags in the Lakes; today's light 15 km/h SW breeze won't help much.
- The south-facing aspect will receive good afternoon sun in early May, which should help evaporate today's light rain relatively quickly if skies clear.
- The long dry spell from April 21–30 means there is no residual deep seepage concern — any dampness today is purely from today's and yesterday's light precipitation.
Warnings
2
- Delicate slab climbing at Quayfoot demands excellent friction — even a thin film of moisture on the surface can make these routes dangerously slippery; do not commit to slab routes unless the rock is genuinely dry to the touch.
- Tomorrow (May 3rd) brings 7mm of rain; do not plan a session for the morning of May 4th without on-site verification.
Reasoning
Today's 1.3mm rain on top of yesterday's 1.5mm means the rock surface is likely damp right now, though cumulative amounts are very small and the preceding 8-day dry spell eliminated any deeper moisture.
The south/SW aspect will catch afternoon sun which helps, but the sheltered position and high humidity (84%) will slow evaporation — expect several hours of drying needed after any rain stops.
Non-porous Borrowdale Volcanic rhyolite faces no structural risk from moisture; the concern is purely friction loss on damp surfaces.
Early May in the Lakes offers reasonable daylight and warmth, but spring weather remains changeable; the forecast shows unsettled conditions returning from tomorrow with 7mm expected on May 3rd.
Contributing Factors
7
1.3mm of rain today with 84% humidity means the rock surface is likely damp, reducing friction on the slab routes that demand excellent grip.
Eight consecutive dry days from April 21–30 with warm temperatures thoroughly dried out any deep seepage or residual moisture from the wet mid-April period.
Humidity at 84% significantly slows surface evaporation, meaning even light rain will linger on the rock longer than usual.
The S/SW aspect captures afternoon sun well in early May, offering the best chance for the rock to dry if skies clear later today.
The sheltered Borrowdale valley setting limits wind-assisted drying, and today's modest 15.5 km/h breeze won't compensate significantly.
Rhyolite/volcanic rock does not absorb water, so surface moisture from today's light rain should clear relatively quickly once conditions improve.
7mm forecast for tomorrow and further scattered rain through to May 6th means conditions are unlikely to improve significantly in the short term.
Recommendations
3
- If visiting today, wait until mid-to-late afternoon and assess the Brown Slabs area by touch — if the rough volcanic texture feels dry and grippy, conditions may be acceptable for lower-grade routes.
- Avoid the upper left section beneath the tree canopy, as drips will persist long after rain stops.
- Consider postponing to May 7th when the first genuinely dry day with lower humidity is forecast, offering the best conditions in the coming week.

Quayfoot Buttress has had an excellent drying spell from April 21–30 with nearly no rain, but 2.3mm fell today (May 1), breaking the dry streak. The south-facing volcanic rock should dry quickly from light rain, but the sheltered valley position and tree canopy may hold residual dampness — a visual check on arrival is warranted.
Based on weather conditions only — does not cover bird nesting restrictions or other access issues.
- The tree canopy above the upper left section can cause persistent drips even hours after rain has stopped, so check this area carefully after today's 2.3mm shower.
- The extended dry spell from April 21–30 (9 consecutive dry days, low humidity, warm temps up to 20°C) means the rock was thoroughly dry before today's rain — only surface moisture needs to clear.
- Borrowdale's sheltered valley position reduces wind-driven drying despite the south-facing aspect, so allow extra time for today's rain to fully evaporate.
- Brown Slabs relies heavily on friction for delicate slab climbing — even a thin film of residual moisture can make these routes significantly harder and more dangerous than in dry conditions.
Warnings
2
- Slab routes on Brown Slabs are particularly friction-dependent — even a slight film of moisture dramatically increases the risk of a slip on these delicate climbs.
- Deteriorating weather from May 2–4 (12.2mm on May 3, humidity 87–93%) means conditions will worsen before they improve.
Reasoning
Today's 2.3mm of rain on previously bone-dry non-porous volcanic rock means only surface moisture is present, but humidity at 63% and the sheltered position may slow evaporation.
The south/south-west aspect and moderate southerly wind (16.6 km/h) should clear surface moisture from open faces within a few hours, though the sheltered valley setting and tree canopy will slow drying in places.
Borrowdale Volcanic rhyolite is non-porous and extremely hard — no structural risk from moisture; the concern is purely friction loss on wet surfaces.
Early May in the Lakes offers reasonable daylight and moderate temperatures (18.7°C today), though the forecast shows a significant deterioration with heavy rain on May 3 and high humidity through the coming week.
Contributing Factors
7
2.3mm fell today, breaking a 9-day dry streak and leaving surface moisture on the rock.
Nine consecutive dry days (April 21–30) with low humidity and warm temperatures ensured the rock was thoroughly dried out before today's rain.
The south/SW aspect maximises solar exposure in early May, accelerating evaporation of surface moisture from today's light rain.
The sheltered Borrowdale valley setting limits airflow across the crag face, slowing wind-driven drying despite moderate 16.6 km/h winds.
Overhanging trees above the upper left section can cause prolonged dripping even after rain stops, potentially keeping sections damp.
Forecast humidity jumps to 88% on May 2 with further light rain (0.9mm), suggesting drying conditions will worsen rather than improve.
BVS rhyolite does not absorb water so only surface moisture needs to evaporate, meaning recovery from light rain is rapid in favourable conditions.
Recommendations
3
- Visit later in the day to allow morning sun to dry surface moisture from today's 2.3mm rain — afternoon conditions on the south face should be significantly better.
- Carefully check the Brown Slabs area and upper left section for residual dampness or tree-canopy drips before committing to slab routes that depend on friction.
- Consider postponing to May 5 if possible, as May 2–4 bring further rain and very high humidity; conditions are unlikely to be reliable until the next dry window.

Quayfoot Buttress has had three full dry days following only a trace of rain (0.2mm on April 26), with warm temperatures up to 18.9°C, low humidity, and good southerly sun exposure. The non-porous BVS rock should be thoroughly dry and offering excellent friction today.
Based on weather conditions only — does not cover bird nesting restrictions or other access issues.
- The tree canopy above the upper left section can cause lingering drips even after the main rock face has dried — worth a visual check on that area despite the extended dry spell.
- Quayfoot's sheltered valley position means overnight dew and humidity can linger into mid-morning; the rock will be at its best from late morning onward once the sun has warmed the south-facing slabs.
- The Brown Slabs area relies on friction-dependent slab climbing where even slight residual moisture dramatically affects grip — today's low humidity and multi-day drying period should provide ideal friction.
- April bird nesting restrictions may be in effect at nearby Borrowdale crags — check BMC RAD for any current closures in the area before visiting.
Reasoning
The last meaningful rain was 3.2mm on April 20, nine days ago, with only a negligible 0.2mm on April 26; the rock surface will be completely dry.
Three consecutive fully dry days with southerly sun, temperatures reaching 17–19°C, and humidity dropping to 48–60% provide excellent drying conditions even for a sheltered crag.
BVS rhyolite is non-porous and extremely hard — there is no structural risk from recent moisture, and the extended dry spell eliminates any surface concern.
Late April conditions are favourable with lengthening days, strengthening sun angle on this south-facing aspect, and temperatures well above freezing overnight — no frost or freeze-thaw risk.
Contributing Factors
6
Three fully dry days and nine days since any significant rain (3.2mm on April 20) ensure the rock surface is thoroughly dry.
Daytime highs of 15–19°C over recent days with overnight lows well above freezing promote rapid evaporation and eliminate frost risk.
Today's humidity at 60% and recent days as low as 48% mean minimal atmospheric moisture to slow drying or cause condensation.
The S/SW aspect maximises solar heating in late April, with the sun high enough to warm the rock effectively from mid-morning.
While shelter slows wind-assisted drying, the extended dry spell renders this irrelevant today; shelter also reduces wind chill for comfortable climbing.
The upper left section beneath tree canopy can hold drips after rain, but after three dry days this should not be an issue.
Recommendations
3
- Conditions are excellent — enjoy the friction on Brown Slabs, which should be at its best from late morning once any overnight dew has burned off.
- Give the upper left section beneath the tree canopy a quick visual check and touch test before committing, as a precaution.
- Minimise chalk use on these classic routes and brush holds after your session — Borrowdale's rock is an irreplaceable resource.
