Condition Analysis
AI-powered assessment using site data and 14-day weather history
Five consecutive dry days with warm temperatures (up to 29°C) and moderate winds on a SW-facing crag provide excellent drying conditions. The last significant rain was 6.5mm on August 9th, and the rock should be well dried by now.
Based on weather conditions only — does not cover bird nesting restrictions or other access issues.
- The woodland canopy was significantly reduced by felling (2020) and Storm Arwen (2021), improving air circulation and drying compared to older guidebook descriptions — but the crag remains broadly sheltered, so wind-assisted drying is moderate rather than strong.
- Steep, pocket-rich Fell Sandstone can trap moisture in horizontal features and undercuts longer than vertical faces — a chalk test on suspect pockets is worthwhile even after extended dry spells.
- The heavy 31.4mm event on July 26th followed by intermittent showers through early August means the rock has had a wet recent history, but five dry days including exceptional warmth (26–29°C on Aug 12–13) have provided strong cumulative drying.
- Approach only via the designated northern gate track — other access routes cross private land and risk losing climber access to this important venue.
Reasoning
The last meaningful rain was 6.5mm on August 9th, followed by five fully dry days with warm temperatures peaking at 29.3°C and moderate SW/W winds — surface and internal moisture should be well depleted.
The SW aspect receives good afternoon solar radiation, and with temperatures of 20–29°C and winds of 17–23 km/h over the drying window, evaporation rates have been strong and comfortably exceed the 48-hour guideline for moderate rain.
With five days of warm, breezy drying after only 6.5mm of rain, internal moisture levels should be well below the threshold for significant strength reduction in the sandstone.
Mid-summer conditions with long daylight hours, warm temperatures, and active vegetation transpiration all favour rapid drying — this is the optimal season for Fell Sandstone climbing.
Contributing Factors
6
Five consecutive dry days since the 6.5mm rain on August 9th comfortably exceeds the 48-hour minimum guideline for moderate rainfall on porous sandstone.
Temperatures reached 26.6°C and 29.3°C on August 12–13, driving strong evaporation and thorough internal drying.
The south-west facing aspect maximises afternoon solar radiation, accelerating surface and sub-surface drying.
Winds of 17–23 km/h from W/SW over the drying period aid moisture removal, though the partially sheltered woodland setting limits full wind effect.
53mm over 28 days including a 31.4mm deluge on July 26th means the broader moisture context has been damp, though recent drying has been very effective.
Steep angles shed water well, but horizontal pockets can trap moisture — worth a quick chalk or touch test on suspect features.
Recommendations
3
- Conditions look good — enjoy the climbing but do a quick chalk test on any pockets or horizontal features that look suspect before committing.
- Use the designated northern gate approach track to maintain positive landowner relations.
- Plan sessions for the next two days (Aug 15–16) as rain is forecast from August 17th onwards.

Four consecutive dry days with warm temperatures (up to 28.5°C today) and moderate SW winds on a SW-facing crag have provided excellent drying conditions since the last significant rain (6.5mm on Aug 9). The rock should be well dried through, and today and the next two days look ideal for climbing.
Based on weather conditions only — does not cover bird nesting restrictions or other access issues.
- The woodland canopy was significantly reduced by felling (2020) and Storm Arwen (2021), so the crag now dries faster than older guidebooks suggest, but it remains broadly sheltered — don't expect fully exposed drying rates.
- Steep pocket-rich Fell Sandstone holds moisture in horizontal features and pockets longer than vertical faces; check deeper pockets with a chalk test before committing.
- Seepage from above remains possible even in dry spells — the condition report from March 2026 specifically notes checking for seepage lines, which can persist from water draining through the hillside above.
- The designated approach is via the northern gate track only; respect this to maintain access.
Reasoning
The last significant rain was 6.5mm on Aug 9, four full days ago, with only trace amounts since; warm temperatures (17–28°C) and moderate humidity (63–74%) suggest the rock surface and interior should be thoroughly dry.
Four days of dry weather with SW aspect receiving direct afternoon sun, temperatures peaking at 28.5°C today, and consistent 17–23 km/h winds provide well above the minimum 48-hour drying window needed after moderate rain on porous sandstone.
With four dry days and warm conditions, internal moisture levels should be well below the threshold for significant strength reduction, and no freeze-thaw risk exists in August.
Mid-summer conditions are optimal for Fell Sandstone climbing, with long days, warm temperatures, and good evaporation potential.
Contributing Factors
6
No meaningful precipitation since 6.5mm on Aug 9, comfortably exceeding the 48-hour minimum drying guideline for moderate rain.
Temperatures have risen from 17°C to 28.5°C over the drying period, driving strong evaporation from the rock.
The SW-facing crag has received direct solar radiation through the afternoon hours, and moderate westerly/SW winds (17–23 km/h) have aided surface drying.
Post-felling and post-Arwen canopy loss means better air circulation and solar exposure than the crag historically received.
Average humidity of 71% over the past week is moderate and not low enough to maximise drying, but today's daytime humidity dropping to 42% is very favourable.
The steep pocket-rich rock can hold small amounts of trapped water in horizontal features longer than flat faces.
Recommendations
3
- Conditions are good — enjoy the climbing but do a quick chalk test on deeper pockets before pulling hard, especially on problems that don't see much traffic.
- Check for seepage lines from above before climbing, particularly on problems near drainage channels in the hillside.
- The forecast window is best today through Aug 15; light rain returns Aug 16–17 so plan sessions accordingly.

The last significant rain was 6.5mm on August 9th, followed by two dry days and warm conditions, but today's 0.3mm trace and evening shower introduce fresh surface moisture. The SW aspect, decent temperatures (~17–26°C), and moderate wind have aided drying, but the pattern of repeated light rainfall events over recent weeks means internal moisture may linger in pockets and features — assess on arrival before committing.
Based on weather conditions only — does not cover bird nesting restrictions or other access issues.
- The woodland canopy loss since 2020/Storm Arwen means the crag now dries faster than older guidebook descriptions suggest, but the steep pocket-rich rock still traps moisture in horizontal features and seepage lines from above.
- The recent rainfall pattern has been intermittent rather than prolonged — 6.5mm on Aug 9, 1.8mm on Aug 6, 7.3mm on Aug 4, and a heavy 31.4mm event on Jul 26 — so the rock has rarely had a sustained dry spell to fully purge internal moisture.
- Seepage from above remains a known issue at Kyloe; even when the face appears dry, water can migrate through the sandstone from the hillside above, especially after the cumulative 53mm over 28 days.
- Today's trace precipitation (0.3mm forecast at 18:00) is negligible but signals the unstable pattern; the afternoon window (11:00–17:00) with humidity dropping to 47–52% and temps above 23°C offers the best drying conditions.
Warnings
2
- Do not assume pockets are dry internally — Kyloe's signature small holds are iron-oxide cemented and especially vulnerable to breakage when moisture is trapped inside.
- Rain is forecast from August 16th (7.2mm) and 17th (3.6mm), so conditions will deteriorate again later this week.
Reasoning
The 6.5mm rain on August 9th was moderate, and while two subsequent dry days with SW winds and temperatures of 17–21°C have aided surface drying, the cumulative 53mm over 28 days and repeated wetting cycles mean internal moisture is likely still present in deeper pockets and features.
The SW aspect receives good afternoon solar radiation, and moderate winds (17–22 km/h from W/SW/S) have helped evaporation; roughly 48–50 hours of dry weather since the Aug 9 rain is marginal for 6.5mm on porous Fell Sandstone, though warm summer temps improve the picture.
With repeated wetting-drying cycles through late July and early August and 53mm cumulative rainfall, there is moderate risk of residual internal moisture weakening the iron-oxide cemented holds that Kyloe's pocket problems depend on — a chalk or touch test is essential before pulling on small features.
Mid-summer conditions are broadly favourable with long days, warm temperatures, and no freeze-thaw risk, but the unsettled Atlantic pattern bringing frequent light rain is preventing the sustained dry spell that Fell Sandstone ideally needs.
Contributing Factors
7
6.5mm fell on August 9th, only ~50 hours ago, which is borderline for adequate drying on porous Fell Sandstone even in good conditions.
53mm over 28 days with frequent wetting events means the rock has rarely fully dried out, risking persistent internal moisture.
Temperatures of 17–26°C over the drying period significantly aid evaporation compared to cooler seasons.
The south-west facing rock benefits from afternoon sun and prevailing W/SW winds at 17–22 km/h, accelerating surface and near-surface drying.
0.3mm forecast this evening and 0.2mm tomorrow adds trivial but unwelcome fresh surface moisture, resetting the drying clock slightly.
Post-felling and Storm Arwen canopy loss means better air circulation and solar access than the crag historically had, improving drying rates.
Average humidity around 70–74% over recent days is not ideal for rapid drying but is acceptable for summer conditions in Northumberland.
Recommendations
3
- Visit during the warm afternoon window (11:00–17:00) when humidity is lowest (~47–52%) and assess each problem individually with a chalk test before pulling on — if chalk darkens, the rock is too damp.
- Avoid low-lying or recessed pockets and any areas showing seepage from above; prioritise steeper, more exposed faces that dry fastest.
- If conditions look marginal today, the forecast for August 14–15 (two consecutive dry days with moderate temps and wind) may offer a better window before rain returns on the 16th.

The last significant rain was 6.5mm on August 9th, with only one full dry day since. While today is dry with moderate temperatures and SW aspect should help, one day of drying after moderate rain on porous Fell Sandstone is borderline — particularly given the steep pocket-rich rock that traps moisture in features. Climbers should visually inspect holds and use a chalk test before committing.
Based on weather conditions only — does not cover bird nesting restrictions or other access issues.
- The crag's steep, pocket-rich rock holds moisture in pockets and horizontal features longer than vertical faces — these are the very holds climbers rely on, so a chalk test on suspect pockets is essential.
- Post-2020 tree felling and Storm Arwen canopy loss mean the crag dries faster than older guidebook descriptions suggest, with improved air circulation and more direct sunlight reaching the rock.
- The recent weather pattern has been unsettled with multiple small rain events (7.3mm on Aug 4, 1.8mm on Aug 6, 6.5mm on Aug 9), meaning the rock has had little opportunity to fully dry out between episodes — cumulative moisture loading is a concern.
- Seepage from above remains possible even when the main face appears dry; the condition report from March notes the importance of checking for seepage lines, which can persist after rain in the woodland setting.
Warnings
2
- Only one dry day has elapsed since 6.5mm of rain on porous Fell Sandstone — internal moisture may still be sufficient to weaken holds even if the surface appears dry.
- Repeated wetting over the past week (15.8mm in 7 days) means cumulative moisture loading is higher than a single rain event would suggest.
Reasoning
6.5mm fell yesterday (Aug 9) with only one dry day elapsed; combined with earlier rain events on Aug 4 (7.3mm) and Aug 6 (1.8mm), the rock has had repeated wetting over the past week and is likely still holding internal moisture despite possible surface drying.
The SW aspect and moderate westerly winds (~18 km/h) today are favourable for drying, and summer temperatures around 16–17°C help, but one day is below the recommended 24–48 hour minimum for light rain on Fell Sandstone and the 6.5mm event was moderate rather than light.
With cumulative wetting over the past week (15.8mm in 7 days) and only one dry day, internal moisture levels may still be elevated enough to reduce hold strength, particularly in the iron-oxide-cemented pockets that define Kyloe's climbing.
Mid-summer conditions with adequate daylight hours and reasonable temperatures are broadly favourable for drying, though the recent spell of higher humidity (averaging 78% over 7 days) has been limiting evaporation rates.
Contributing Factors
7
6.5mm fell on August 9th with only one dry day since, below the recommended 24–48 hour minimum drying window for Fell Sandstone.
15.8mm over the past 7 days across multiple events means the rock has had limited opportunity to fully dry between rain episodes.
The south-west facing aspect receives good solar radiation in summer and moderate westerly winds (~18 km/h) help move moist air from the rock surface.
Temperatures of 16–17°C today and rising to 20°C+ over coming days support reasonable evaporation rates.
Average humidity of 78% over the past 7 days limits net evaporation from the rock surface, slowing drying.
Post-felling and Storm Arwen canopy loss means better air circulation and more direct sunlight than historic descriptions suggest.
Steep pocket-rich features trap and hold moisture longer than smooth vertical faces, and these pockets are the primary climbing holds.
Recommendations
3
- Wait until tomorrow (Aug 11) for a more confident session — two full dry days with improving conditions and lower humidity (72%) will significantly improve drying.
- If visiting today, perform a chalk test on pockets and horizontal features before climbing; if chalk darkens or the rock feels cool and clammy, back off.
- Avoid lower sections of the crag and any areas with visible seepage lines from above — these will be the last to dry.

Today saw 3.8mm of rain on top of a generally unsettled recent period (13.6mm in the last 7 days, including 7.3mm on Aug 4th and 1.8mm on Aug 6th), leaving the rock almost certainly damp internally despite the SW aspect. With only a brief dry spell of two days (Aug 7–8) before today's rain, the sandstone has not had adequate time to dry and we recommend waiting at least 1–2 full dry days before climbing.
Based on weather conditions only — does not cover bird nesting restrictions or other access issues.
- The woodland setting, though more open since 2020 tree felling and Storm Arwen, still provides shelter that reduces wind-driven drying — don't assume the crag dries as fast as fully exposed Fell Sandstone outcrops.
- Steep pocket-rich rock holds moisture in horizontal features and undercuts longer than vertical faces; pockets should be individually checked even when the main face appears dry.
- The 31.4mm deluge on July 26th was the heaviest event in the past month and may have deeply saturated the rock mass — subsequent intermittent showers have prevented full internal drying.
- Seepage from above remains possible after rain despite reduced canopy; the condition report from March noted the importance of checking for seepage and using a chalk test on suspect holds.
Warnings
2
- Do not climb today — rain has fallen and the rock is wet; climbing on damp Fell Sandstone causes permanent hold damage.
- Pockets and horizontal features may appear surface-dry while remaining saturated internally — always chalk-test suspect holds before pulling on them.
Reasoning
Today's 3.8mm of rain, following 7.3mm on Aug 4th and 1.8mm on Aug 6th with only two dry days in between, means the rock is very likely still holding significant internal moisture despite any surface drying.
The SW aspect and moderate wind (~17–22 km/h from W/SW) provide reasonable drying potential, but with rain falling today and humidity at 83%, effective evaporation has been minimal and the two dry days (Aug 7–8) were insufficient to clear the cumulative moisture from recent showers.
Fell Sandstone loses 10–50% of its compressive strength when wet, and the pocket-rich holds at Kyloe are particularly vulnerable to grain loosening and breakage under load when internally saturated.
Summer temperatures (~16–21°C) and longer daylight hours favour drying, but the recent pattern of intermittent showers and above-average humidity (79% average over 7 days) has been working against a full dry-out.
Contributing Factors
7
Moderate rainfall today has re-wetted the rock surface and replenished internal moisture, resetting any drying progress from the two preceding dry days.
13.6mm over the last 7 days across multiple events (including 7.3mm on Aug 4th) has kept the rock in a repeatedly wetted state with insufficient drying windows.
The 31.4mm event on July 26th would have deeply saturated the sandstone, and subsequent intermittent rain has prevented complete internal drying.
The south-westerly aspect receives good solar radiation and moderate wind exposure aids evaporation, giving above-average drying potential when dry weather arrives.
Temperatures of 16–21°C support reasonable evaporation rates, significantly better than winter or early spring conditions.
Today's humidity of 83% substantially slows evaporative drying from the rock surface.
Despite canopy loss, the partially sheltered woodland setting reduces airflow at rock level, slowing drying compared to fully exposed crags.
Recommendations
3
- Wait at least 1–2 full dry days after today's rain before visiting; tomorrow (Aug 10) is too soon given cumulative moisture.
- If visiting on Aug 11 or later after dry weather, perform a chalk test on holds and check for seepage from above before committing to any problems.
- Focus on steep or overhanging problems first as these shed water fastest; avoid slabs and horizontal pocket features until you are confident they are dry throughout.

The crag received 7.3mm of rain on August 4th, followed by light precipitation on the 5th, 6th, and today (8th), meaning there have been zero consecutive fully dry days. Despite reasonable summer temperatures and SW winds favouring this aspect, the rock has not had an adequate uninterrupted drying window, and steep pockets will retain moisture internally. We recommend waiting.
Based on weather conditions only — does not cover bird nesting restrictions or other access issues.
- The woodland canopy was significantly reduced by felling (2020) and Storm Arwen (2021), improving air circulation, but the crag remains broadly sheltered — drying is better than historic guides suggest but still slower than fully exposed crags.
- Steep, pocket-rich Fell Sandstone holds moisture in horizontal features and undercuts; these areas can remain damp long after the face appears dry.
- The 31.4mm deluge on July 26th will have deeply saturated the rock, and subsequent intermittent light rain events (July 28, 31, Aug 1, 3, 4, 5, 6, 8) have prevented any sustained drying period from fully clearing that deep moisture.
- Seepage from above remains possible even after canopy loss — the condition report from March 2022 specifically advises checking for seepage and chalk-testing holds before committing.
Warnings
2
- Climbing on internally damp Fell Sandstone risks permanent hold breakage — the iron-oxide pocket holds at Kyloe are irreplaceable.
- The surface may appear dry while the interior remains saturated after weeks of intermittent rain; do not rely on visual inspection of the face alone.
Reasoning
The rock has received intermittent precipitation throughout the last two weeks with no period longer than two consecutive fully dry days since the heavy 31.4mm event on July 26th, meaning internal moisture levels are very likely still elevated despite surface drying.
The SW aspect and moderate SW/W winds (19–37 km/h) are favourable for surface drying, but with only brief dry windows between repeated light rain events (0.1–1.8mm), the rock has not had the sustained 48–72+ hours of dry weather needed to clear deep moisture from the heavy July 26th soaking.
Fell Sandstone loses up to 50% compressive strength when wet, and the iron-oxide-cemented pocket holds characteristic of Kyloe are particularly vulnerable to grain loosening and breakage if climbed on while internally damp.
Summer temperatures (15–21°C) and longer daylight hours aid evaporation, but the persistently moderate-to-high humidity (70–89% over recent days) limits drying efficiency significantly.
Contributing Factors

31.4mm fell on July 26th — a heavy soaking that would deeply penetrate the porous sandstone — followed by repeated light rain preventing full recovery.
Zero fully dry consecutive days as of today, with trace-to-light precipitation on Aug 1, 3, 4, 5, 6, and 8 repeatedly re-wetting the surface.
7.3mm on August 4th is a moderate fall that re-saturated already-damp rock, resetting the drying clock significantly.
The SW-facing crag receives good solar radiation and recent SW/W winds (19–37 km/h) promote evaporation when it is not raining.
Temperatures of 14–21°C over the past week provide reasonable evaporative potential, though not exceptional.
Average humidity of 78% over the last seven days limits evaporative efficiency and slows internal drying.
Post-felling and post-Storm Arwen canopy loss means better air circulation than historical guides suggest, aiding drying somewhat.
The steep, pocket-heavy rock at Kyloe holds water in horizontal features and crevices longer than a simple vertical face would.
Recommendations
3
- Wait for at least two full consecutive dry days before visiting — the rock needs an uninterrupted drying window to clear the accumulated moisture from recent weeks.
- If you do visit, use the chalk-dust test on holds before climbing: press dry chalk onto the rock and check for darkening, which indicates residual moisture.
- Focus any assessment on lower sections and deep pockets, which will be the last areas to dry — if these are damp, do not climb.

Heavy rain on July 26 (31.4mm) was followed by repeated light precipitation events through August 6 (1.8mm), with the most significant being 7.3mm on August 4. Only one full dry day has elapsed since the last rain (1.8mm on Aug 6), which is insufficient drying time for Fell Sandstone even with today's favourable SW wind and moderate temperatures. The rock is very likely still holding internal moisture, particularly in the steep pockets that characterise this crag.
Based on weather conditions only — does not cover bird nesting restrictions or other access issues.
- The woodland canopy loss since 2020/2021 has improved air circulation and drying, but the crag remains broadly sheltered — wind-assisted drying is moderate, not dominant.
- Steep pocket-rich rock at Kyloe holds moisture in horizontal features and finger pockets longer than vertical faces; these are exactly the holds climbers weight most heavily.
- The SW aspect receives good afternoon sun in summer, which helps surface drying, but NE winds (prevailing recently) blow across the sheltered side rather than directly onto the face, reducing evaporation.
- The March 2026 condition report notes the importance of checking for seepage from above and chalk-testing — this remains critical given recent rainfall patterns.
Warnings
2
- Do not rely on surface dryness — Fell Sandstone can appear dry while retaining 80%+ of its moisture-related strength loss internally.
- Pocket holds at Kyloe are iron-oxide cemented and particularly vulnerable to breakage when wet; pulling hard on damp pockets risks permanent route damage.
Reasoning
The cumulative rainfall pattern — 31.4mm on July 26 followed by scattered light precipitation on July 28 (2.8mm), July 31 (1.9mm), August 3 (0.5mm), August 4 (7.3mm), and August 6 (1.8mm) — means the rock has never had a sustained drying window and is very likely retaining significant internal moisture despite surface drying today.
Only one dry day with SW wind at 22.7 km/h and 70% humidity has elapsed since the last rain; the SW aspect helps with solar gain, but a single day is well short of the 1–2 dry day minimum recommended for this crag, especially given the saturated recent history.
With repeated wetting cycles over the past two weeks keeping internal moisture elevated, the iron-oxide cemented pockets and small holds are at meaningful risk of grain loosening and breakage under climbing loads.
Summer conditions with temperatures around 15–19°C and moderate humidity are adequate for drying, but the persistent rainfall pattern through late July and early August has prevented the rock from reaching a genuinely dry baseline.
Contributing Factors
6
Rainfall on six of the past twelve days (totalling ~14.5mm since July 26's 31.4mm deluge) has prevented the rock from establishing a sustained dry period.
A single dry day since 1.8mm on August 6 is below the minimum 1–2 dry days recommended for Kyloe, and well below what the cumulative moisture loading demands.
This moderate rainfall event three days ago would itself require at least 48 hours of good drying, and conditions since have included further rain on August 6.
Today's 22.7 km/h SW wind, 70% humidity, and 18.6°C temperature onto the SW-facing crag provide good drying conditions, but one day is not enough.
Post-2020 tree felling and Storm Arwen canopy loss have improved air circulation and solar access compared to historical conditions.
Average humidity of 78% over the past week has slowed evaporation and kept the drying rate below optimal.
Recommendations
3
- Wait for at least one more full dry day (ideally two) before climbing — the rock needs time to release internal moisture from the cumulative wetting of recent weeks.
- If visiting, perform the chalk test on holds and check the ground at the crag base: if soil or leaf litter is damp, the rock is still too wet internally.
- Avoid the lower sections and deep pockets first — these retain moisture longest; if conditions improve, upper and overhanging sections will be ready first.

The crag received 1.9mm of rain in the early hours of today (6 Aug), on top of 7.3mm on 4 Aug and a very wet period including 31.4mm on 26 July — the rock has not had a sustained dry spell. Although the afternoon looks dry with dropping humidity, the combination of recent repeated wetting events and pocket-rich sandstone that traps moisture means internal dampness is highly likely.
Based on weather conditions only — does not cover bird nesting restrictions or other access issues.
- The steep, pocket-rich Fell Sandstone at Kyloe holds moisture in horizontal features and pockets long after the surface appears dry — chalk-test any suspect holds before committing.
- Post-2020 tree felling and Storm Arwen canopy loss means the crag now dries faster than older guides suggest, but the woodland floor and base of the crag can still remain damp when exposed rock above looks dry.
- Seepage from above is a known issue at Kyloe even after modest rain — check tops and horizontal breaks for active drip lines, especially on the left-hand walls.
- The SW aspect and improved air circulation since canopy loss are helpful, but persistent NE winds over recent weeks have limited direct solar drying on this SW-facing crag.
Warnings
2
- Fell Sandstone loses up to 50% of its compressive strength when wet — climbing on damp pockets risks permanent hold breakage on irreplaceable problems.
- The surface may appear dry while the interior remains saturated; always chalk-test suspect holds and check for seepage from above.
Reasoning
Rain today (1.9mm) follows 7.3mm on 4 Aug, 0.5mm on 3 Aug, and a heavy 31.4mm event on 26 July, meaning the rock has been repeatedly re-wetted over the past 11 days with no sustained dry period exceeding 3 days.
Despite SW aspect and partial wind exposure, the prevailing NE–N winds of recent weeks have not driven direct drying on the SW-facing rock, and today's rain resets the drying clock to zero — meaningful drying cannot begin until tomorrow.
Repeated wetting cycles over the past two weeks will have kept internal pore saturation elevated, increasing the risk of grain loosening and hold breakage on the pocket-dependent problems Kyloe is known for.
Summer temperatures (14–21°C) and moderate humidity (65–77%) are broadly helpful for drying, but the unsettled pattern with rain every few days has prevented the rock from fully drying out between events.
Contributing Factors
6
1.9mm fell between 01:00 and 04:00 this morning, re-wetting the rock surface and resetting the drying clock.
46.9mm in the last 28 days including 31.4mm on 26 July and 7.3mm on 4 Aug means the rock has been repeatedly saturated without adequate drying intervals.
The SW-facing aspect will receive afternoon sun and the forecast SW winds from tomorrow should actively assist drying on this face.
Horizontal pockets and features characteristic of Kyloe trap water and extend internal drying time well beyond what flat surfaces would require.
Reduced woodland canopy since 2020/2021 allows better airflow and solar access, improving drying rates compared to historic conditions.
No rain forecast from tomorrow through at least 12 August, with moderate temperatures and dropping humidity — excellent drying conditions approaching.
Recommendations
3
- Do not climb today — rain fell this morning and the rock will still be damp internally despite any surface drying this afternoon.
- Wait until at least 8 August (two full dry days after today's rain) before visiting, and perform a chalk test on holds before climbing.
- On arrival, check the base of the crag and woodland floor — if the ground is damp, the rock is almost certainly still wet internally.

Kyloe-in-the-Woods is currently wet and unsuitable for climbing. Today has seen ~6.4mm of rain (mostly early morning through early afternoon), following a week of intermittent light precipitation and a major 31mm event on July 26th; the rock will be thoroughly saturated. Tomorrow brings a further 8mm, so meaningful drying cannot begin until August 6th at the earliest.
Based on weather conditions only — does not cover bird nesting restrictions or other access issues.
- The woodland setting, though more open since 2020 felling and Storm Arwen, still provides partial shelter that reduces wind-driven drying — pockets and horizontal breaks will hold moisture longer than exposed faces.
- Steep pocket-rich Fell Sandstone at Kyloe traps water in features; horizontal pockets and scoops can remain wet long after vertical faces appear dry — always chalk-test suspect holds.
- Seepage from above remains a known issue despite canopy loss; after heavy rain, water percolates through the soil and organic matter above the crag and can weep for days.
- The SW aspect is favourable for afternoon solar drying in summer, but the recent persistent cloud cover (100% today) and high humidity (~90%) are severely limiting evaporation.
Warnings
2
- Fell Sandstone loses significant structural strength when wet — climbing on damp rock risks snapping holds and permanently damaging classic problems at one of Northumberland's finest bouldering venues.
- The surface may appear dry before the interior has dried; always chalk-test suspect holds and check horizontal pockets, which trap water longest.
Reasoning
The rock is currently wet from 6.4mm of rain today on top of intermittent precipitation over the past week (0.5mm on Aug 3, 0.2mm on Aug 1, 1.9mm on Jul 31, 2.8mm on Jul 28) and the heavy 31mm event on July 26th — the sandstone has had no sustained drying window and will be saturated well beyond the surface.
With today's rain only ceasing mid-afternoon, near-100% humidity through the morning, and a further 8.1mm forecast for tomorrow, no meaningful drying can begin until August 6th; the SW aspect and moderate wind will help once dry weather arrives, but at least 48 hours of dry conditions from that point will be needed.
Fell Sandstone loses up to 50% of compressive strength when wet, and the pocket-rich nature of Kyloe means the small iron-oxide-cemented holds that define the bouldering are particularly vulnerable to breakage under load — climbing now risks permanent, irreversible damage.
Mid-summer temperatures (~17–22°C) and longer daylight hours will aid drying once rain stops, but the recent pattern of high humidity (76% average over 7 days) and frequent light precipitation is keeping the rock in poor condition.
Contributing Factors
7
6.4mm has fallen today with the heaviest burst (2.5mm) at 13:00, thoroughly wetting all surfaces and replenishing internal moisture.
8.1mm is forecast for August 5th, which will reset any minor drying that occurs this evening.
44mm over 28 days including a 31mm deluge on July 26th means the sandstone has had no opportunity to dry internally, even if surfaces occasionally appeared dry.
Humidity has averaged 76% over the past week and is 90% today, severely limiting evaporative drying.
The south-west aspect receives good afternoon sun and mid-summer temperatures of 17–22°C will drive reasonable drying once precipitation ceases and skies clear.
Canopy loss from 2020 felling and Storm Arwen means better airflow through the crag than historical descriptions suggest, which will aid drying once conditions allow.
Winds of 21–28 km/h from SW/NW are forecast for August 6–8, which will assist surface drying once rain stops.
Recommendations

- Do not visit Kyloe today or tomorrow — the rock is wet and further rain is imminent; climbing on saturated Fell Sandstone causes irreversible hold damage.
- The earliest realistic window to assess conditions is August 8th, after approximately 48 hours of drier weather from August 6th, but even then a chalk-test and visual inspection of pockets is essential.
- If visiting later this week, check the ground at the crag base — if the soil and leaf litter are damp, the rock is still holding internal moisture regardless of surface appearance.
Do Not Climb

The rock is currently wet from today's intermittent showers (2mm spread across the morning/early afternoon), and heavy rain (10.4mm) is forecast for tomorrow. With 31.4mm on July 26th, further rain on July 28th and 31st, and today's precipitation, the sandstone has had insufficient sustained dry periods to fully dry out internally. Conditions are unsuitable for climbing today and will worsen over the coming days.
Based on weather conditions only — does not cover bird nesting restrictions or other access issues.
- The woodland setting, though more open since 2020 felling and Storm Arwen, still provides partial shelter that reduces wind-driven drying — the SE wind today is partially blocked by remaining trees.
- Steep pocket-rich rock at Kyloe holds moisture in horizontal features and solution pockets long after the main face appears dry; these are the holds climbers rely on most.
- The heavy 31.4mm event on July 26th would have deeply saturated the rock, and only 4-5 genuinely dry days followed before today's rain re-wetted the surface — internal moisture levels are likely still elevated.
- Seepage from above remains a concern even after canopy loss; the hillside above the crag drains through the rock, and recent cumulative rainfall (42.4mm in 28 days) keeps the water table active.
Warnings

- Fell Sandstone loses up to 50% of its compressive strength when wet — climbing on damp rock risks permanent hold breakage on Kyloe's irreplaceable pocket problems.
- The surface may appear dry during brief afternoon dry spells today, but internal moisture from recent cumulative rainfall makes the rock structurally compromised — do not be deceived by surface dryness.
Reasoning
The rock is currently wet from today's 2mm of intermittent showers, and prior to today had only 1-2 fully dry days since the last light rain on August 1st, with deep saturation from the 31.4mm event on July 26th likely still present internally.
The SW aspect would normally aid drying, but today's 100% cloud cover, 86% average humidity, and SE wind direction (sheltered side for a SW-facing crag) have provided minimal drying — and the showers have actively re-wetted the surface.
With repeated wetting cycles over recent weeks (31.4mm on Jul 26, 2.8mm on Jul 28, 1.9mm on Jul 31, and today's rain), the sandstone's iron oxide cement and grain bonds are under cumulative stress, making hold breakage a real concern particularly in the pocket features.
Summer temperatures are moderate (15-17°C) which aids drying in principle, but the persistent high humidity (74% average over 7 days) and frequent cloud cover are limiting evaporation rates well below summer norms.
Contributing Factors

Intermittent showers totalling ~2mm have fallen through this morning and early afternoon, directly wetting the rock surface and re-saturating near-surface pores.
The 31.4mm deluge on July 26th would have deeply saturated the high-porosity sandstone, and only ~5 dry days followed before further rain on the 31st — insufficient for complete internal drying.
10.4mm forecast for August 4th with 92% humidity will thoroughly re-wet any partially dried rock, resetting the drying clock entirely.
Humidity has averaged 74% over the past week and is 86% today, significantly reducing evaporation rates from the rock surface.
The south-westerly aspect would normally provide good solar drying, but persistent 100% cloud cover today and overcast forecasts negate most of this advantage.
Wind speeds of 18-21 km/h this afternoon provide some air movement to aid surface drying, though the partially sheltered woodland setting reduces effectiveness.
Recommendations
3
- Do not climb today or in the coming days — the rock is actively wet and heavy rain is forecast for tomorrow, with further showers through to August 8th.
- Monitor conditions from August 9th onwards if the forecast dry day materialises; you would need at least 48 hours of genuinely dry weather with moderate wind before considering a visit.
- When conditions eventually improve, apply the chalk-dust test to pockets and horizontal features before climbing — these hold moisture longest at Kyloe and are the holds most likely to fail.
