AI-powered assessment using site data and 14-day weather history
The last significant rain was 13.3mm on Aug 19, followed by 2.3mm on Aug 20 and trace amounts on Aug 21 and 25. There have been approximately 4.5 dry days since the last meaningful precipitation (0.4mm on Aug 25), but humidity has been high (78% average over the past week) and today's humidity is very high (89% daily, peaking at 97% overnight), limiting drying effectiveness. A visual check on arrival is essential, particularly of pockets and lower sections.
Based on weather conditions only — does not cover bird nesting restrictions or other access issues.
- The woodland canopy was significantly reduced by felling in 2020 and Storm Arwen in 2021, so air circulation is better than older guidebooks suggest, but the site remains broadly sheltered — reducing wind-assisted drying compared to fully exposed crags.
- Steep pocket-rich rock at Kyloe holds moisture in horizontal features and undercuts; these are the last areas to dry and the first to re-wet from seepage above.
- The 13.3mm event on Aug 19 was the heaviest single-day rainfall in the past month, and combined with follow-up rain on Aug 20–21, the rock will have been thoroughly wetted — the subsequent 4–5 dry days in moderate conditions should have allowed significant drying, but today's very high humidity (89–97%) is actively slowing evaporation.
- Heavy rain is forecast from tomorrow (10.2mm Aug 27, 16.1mm Aug 28), so today may be the last viable window for nearly a week.
Warnings
2
- Heavy rain is forecast for Aug 27–28 (26mm+ combined) — do not climb after this without allowing at least 2–3 full dry days for the rock to recover.
- Today's overnight humidity exceeds 95%, which may cause condensation on the rock — if arriving early morning, surfaces may be damp even without rainfall.
Reasoning
The rock received 13.3mm on Aug 19 plus 2.3mm on Aug 20, followed by about 5 dry days (with a trace 0.4mm on Aug 25); surface rock on the SW-facing aspects should be largely dry, but deep pockets and lower sections may retain internal moisture given persistently high humidity.
SW aspect and partial wind exposure have aided drying since Aug 20, but average humidity of 78% over the past week and today's 89–97% humidity significantly slow evaporation — drying has been adequate but not ideal for full confidence.
Structural risk is moderate — the Aug 19 soaking was significant enough to saturate porous Fell Sandstone, and while 5+ days of drying in summer temperatures (~14–19°C) should have removed most moisture, the pocket-rich holds that define Kyloe are the most vulnerable features.
Mid-to-late summer provides reasonable temperatures for drying (averaging 13.5°C this week), but this has been a wetter-than-average August with 44mm in 28 days, keeping background moisture levels elevated.
Contributing Factors

The last significant rain (13.3mm) fell on Aug 19, giving approximately 6 days of mostly dry weather — meeting the 48–72hr guideline for heavy rain in reasonable conditions.
Today's humidity ranges from 75% in the afternoon to 97% overnight, substantially reducing evaporation rates and potentially allowing condensation on the rock surface.
The south-westerly aspect receives good solar radiation during summer afternoons, accelerating surface drying on exposed faces.
A trace 0.4mm fell on Aug 25, not enough to re-saturate but enough to re-wet the surface and slightly reset drying on already-damp features.
Despite canopy loss, the crag remains partially sheltered and wind-assisted drying is reduced compared to fully exposed Northumberland crags.
10.2mm forecast for Aug 27 and 16.1mm for Aug 28 will thoroughly re-wet the rock — today is effectively the last possible window before a prolonged wet spell.
Recommendations
3
- If visiting today, go in the early-to-mid afternoon (11:00–16:00) when humidity is lowest (~75–80%) and any residual surface moisture has had the best chance to evaporate.
- Perform a thorough chalk test on pockets and lower sections before committing to any problem — if chalk darkens or smears, the rock is still too damp internally.
- Given the heavy rain forecast from tomorrow, do not plan any Kyloe sessions for the rest of the week without at least 48 hours of subsequent dry weather.

Three full dry days following a wet spell (13.3mm on Aug 19, 2.3mm on Aug 20) with today showing excellent drying conditions — low humidity, sunshine, and moderate wind. The rock should be largely dry on the main steep faces, but pockets and lower sections may still hold residual moisture given the high cumulative rainfall and moderate temperatures; 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.
- The woodland canopy loss since 2020/2021 means the crag now dries faster than older guidebook descriptions suggest, but the remaining shelter still reduces wind effectiveness compared to fully exposed crags.
- Steep pocket-rich rock is characteristic of Kyloe — deep pockets can trap and hold moisture long after the main face appears dry, so chalk-test individual holds before pulling on them.
- Seepage from above has been noted even in otherwise dry conditions; the Aug 19 heavy rain (13.3mm) may still be feeding seepage lines from the hillside above the crag.
- Rain returns tomorrow (Aug 25) with a prolonged wet and very humid spell forecast through Aug 29 — today represents the last viable climbing window for potentially a week or more.
Warnings
2
- Rain is forecast from tomorrow (Aug 25) through at least Aug 29 with 32mm expected — conditions will deteriorate sharply and the crag will likely be unsuitable for climbing for several days after the rain ends.
- If any holds feel cool, tacky, or show chalk darkening, stop climbing immediately — surface-dry Fell Sandstone with internal moisture is at serious risk of permanent hold damage.
Reasoning
The last significant rain was 13.3mm on Aug 19 followed by 2.3mm on Aug 20 and a trace 0.1mm on Aug 21, giving roughly 3 full dry days by today — borderline adequate for Fell Sandstone after moderate rainfall, though the preceding weeks were also wet (46.6mm over 28 days).
The SW aspect has received good solar radiation over the last three dry days (Aug 22–24), with today's conditions particularly favourable at 50–53% humidity and clearing skies from mid-morning, and moderate wind aiding evaporation — this is solid but not exceptional drying for the 15.7mm deposited on Aug 19–20.
Internal moisture may still be present in deeper features and at the base of the crag given the moderate drying period; climbing on pockets that appear surface-dry but retain internal moisture risks grain loosening and permanent hold damage.
Mid-to-late summer temperatures (15–19°C) are adequate for drying and there is no freeze-thaw concern, but the recent pattern of frequent showers and above-average humidity has limited cumulative drying potential.
Contributing Factors
6
Three consecutive dry days since the last significant rain on Aug 19–20 meets the minimum community guideline of two dry days, though only just for the heavier 13.3mm event.
Today's clear skies, humidity dropping to 50%, and moderate SE wind provide strong evaporative conditions on the SW-facing rock.
46.6mm over the past 28 days with multiple wet events means the rock has been repeatedly re-saturated, potentially leaving deeper internal moisture despite surface drying.
Kyloe's characteristic deep pockets and horizontal breaks can trap water that takes longer to evaporate than the main face surface.
Post-2020 tree felling and Storm Arwen canopy loss mean better air circulation and solar access than the crag historically had.
Forecast rain from Aug 25–29 (32mm total) with very high humidity (86–96%) means today is the last window before a prolonged wet spell.
Recommendations
3
- Chalk-test holds before committing — press dry chalk onto the rock surface and check for darkening, especially inside pockets and on lower sections.
- Focus on the steeper, more overhanging faces which shed water fastest and have had the best drying; avoid slabby or low-angled rock and anything near visible seepage.
- Climb during the afternoon window (roughly 11:00–17:00) when humidity is lowest and solar warming is at its peak for the best surface conditions.

After 13.3mm of rain on Aug 19 followed by lighter rain on Aug 20 and trace amounts on Aug 21, the crag has had approximately two dry days (Aug 22–23) with moderate temperatures and light-to-moderate wind. Conditions are likely approaching climbable on the steeper, more exposed faces, but pockets and lower sections may still hold internal moisture, so on-site assessment is essential.
Based on weather conditions only — does not cover bird nesting restrictions or other access issues.
- The woodland canopy loss from 2020 felling and Storm Arwen means the crag now dries faster than older guidebooks suggest, but the remaining shelter reduces wind-driven drying compared to fully exposed crags.
- Steep pocket-rich rock is characteristic of Kyloe — pockets trap and hold water internally even when the surface appears dry, requiring careful chalk-testing before committing to problems.
- Seepage from above remains a known issue despite reduced canopy; the Aug 19 rain (13.3mm) could still be feeding seepage lines, particularly on problems below drainage channels.
- The forecast deteriorates significantly from Aug 25 onwards with rain returning, so today (Aug 23) and tomorrow (Aug 24) represent the best window before a prolonged wet spell.
Warnings
2
- Do not assume pockets are dry because the surface rock looks dry — Fell Sandstone loses significant strength at very low internal moisture levels.
- Rain is forecast from Aug 25 onwards; if you miss the Aug 23–24 window, conditions are unlikely to be suitable again until several days after the rain clears.
Reasoning
The 13.3mm on Aug 19 plus 2.3mm on Aug 20 delivered a substantial wetting; two full dry days have elapsed but with average humidity around 75% and moderate temperatures (~15–16°C), internal moisture likely persists in deeper pockets and lower sections.
The SW aspect provides reasonable solar radiation during afternoon hours, and moderate westerly winds (12–20 km/h) over the two dry days have aided surface drying, but the partial shelter of the woodland setting limits full wind-driven evaporation.
With only two dry days after ~15.6mm of cumulative rain over Aug 19–20, there is a moderate risk that internal saturation in pockets and horizontal features could still cause hold weakening, particularly on less-steep terrain.
Mid-to-late August provides adequate daylight and reasonable temperatures for drying, though the recent run of cool, humid days (average 13.5°C, 79% humidity over the last week) has slowed evaporation compared to typical summer conditions.
Contributing Factors

13.3mm fell on Aug 19 with a further 2.3mm on Aug 20, delivering significant moisture to the porous Fell Sandstone only 3–4 days ago.
Aug 22 and Aug 23 have been dry with no precipitation, meeting the minimum community guideline of two dry days for porous rock.
Temperatures of 15–18°C, humidity around 71–73%, and winds of 12–14 km/h provide adequate but not exceptional drying — not the warm, breezy conditions that would give full confidence.
The south-west facing aspect receives good afternoon and evening solar radiation, accelerating surface and near-surface drying.
Kyloe's characteristic deep pockets and horizontal features trap water and dry more slowly than flat or overhanging faces.
The 79% average humidity over the past week has slowed evaporation rates, meaning drying has been less efficient than temperature alone would suggest.
The forecast shows rain from Aug 25 onwards, with 11.2mm on Aug 27 and 8.7mm on Aug 28, meaning conditions will deteriorate again soon.
Recommendations
3
- Visit tomorrow (Aug 24) for the best window — chalk-test all holds before climbing, especially pockets and features below seepage lines.
- Focus on the steepest, most overhanging problems which will have dried fastest; avoid slabby or lower-tier rock where moisture lingers.
- If the ground at the base of the crag feels damp rather than sandy-dry, do not climb — this indicates internal moisture remains.

Heavy rain on Aug 19 (13.3mm) followed by further rain on Aug 20 (2.3mm) means the rock has had less than two full dry days to recover, with only today (Aug 22) and a trace-amount day on Aug 21 as drying time. Given high average humidity (80%) over the past week and moderate temperatures, internal moisture is likely still present — especially 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 setting, though more open since 2020 felling and Storm Arwen, still provides partial shelter that reduces wind-driven drying compared to fully exposed crags.
- Steep pocket-rich rock holds moisture in concave features and horizontal breaks longer than flat or overhanging faces — these are the holds climbers rely on most.
- Seepage from above remains a known issue even when the face appears dry; the condition report advises a chalk test on suspect holds.
- The cumulative 25.3mm over the past 7 days (and 78mm over 28 days) means the rock has been repeatedly re-wetted before fully drying, increasing the risk of deep internal saturation.
Warnings
2
- The rock may appear surface-dry while retaining significant internal moisture — this is the most dangerous scenario for hold breakage on Fell Sandstone.
- Repeated wet-dry cycles this month mean cumulative weakening may be greater than a single rain event would suggest; treat holds with extra care.
Reasoning
With 13.3mm on Aug 19 and 2.3mm on Aug 20, followed by only ~1.5 dry days at moderate temperatures (14–16°C) and high humidity (79–82%), the rock is very likely still holding internal moisture despite potentially appearing surface-dry.
The SW aspect would normally aid drying, but moderate wind speeds (~16–22 km/h), NW direction today (not hitting the SW face optimally), and humidity around 71–79% mean drying has been sluggish — well short of the recommended 48–72 hours of good drying conditions after >10mm rainfall.
Fell Sandstone loses up to 50% compressive strength when wet, and the iron-oxide cemented pockets at Kyloe are particularly vulnerable to grain loosening under load if internal moisture persists.
Late summer conditions are broadly favourable for drying, but the recent spell of cool, humid, unsettled weather has been more typical of early autumn, limiting drying potential.
Contributing Factors
7
13.3mm fell on Aug 19 with a further 2.3mm on Aug 20, delivering a significant wetting event less than 48 hours ago.
Only ~1.5 dry days have elapsed since the last meaningful rain, well below the 48–72 hour guideline for >10mm events on porous sandstone.
Average humidity over the past 7 days is 80%, significantly slowing evaporative drying from the rock surface.
78mm over 28 days with repeated rain-then-partial-dry cycles means the rock has rarely achieved full internal drying this month.
The south-west facing aspect and mid-teen temperatures provide reasonable solar energy for surface drying when the sun is out.
Reduced canopy from felling and Storm Arwen allows better airflow and solar access than older guides suggest, modestly aiding drying.
Wind at ~16 km/h from NW today provides some drying benefit but is not strongly aligned with the SW-facing rock and is not strong enough to drive rapid moisture removal.
Recommendations
3
- Wait at least one more full dry day (ideally until Aug 24) before visiting, and only then if humidity drops and conditions remain rain-free.
- If you do visit, perform a chalk test on pockets and horizontal features before committing — white chalk on dry rock stays powdery; on damp rock it darkens or clumps.
- Check for seepage from above, particularly on upper sections where drainage from the hillside above can persist for days after rain.

The crag received 13.3mm of rain on August 19, followed by further light rain on the 20th (2.3mm) and today (0.8mm), with no consecutive dry days yet. Despite the SW aspect and summer temperatures, the rock has not had adequate drying time and the pockets that define Kyloe's climbing will be holding moisture internally.
Based on weather conditions only — does not cover bird nesting restrictions or other access issues.
- The steep, pocket-rich nature of Kyloe means water pools in horizontal features and finger pockets, which take significantly longer to dry than flat faces.
- Post-2020 canopy loss has improved air circulation and reduced drip/condensation, but the crag remains broadly sheltered — wind drying is moderate, not aggressive.
- The last five days have seen 26mm of cumulative rainfall with high average humidity (79%), meaning the rock has been repeatedly re-wetted before it could fully dry from the heavy 13.3mm event on Aug 19.
- The only recent condition report (March 2026) notes the importance of checking for seepage from above and chalk-testing — this remains essential given recent rain patterns.
Warnings
2
- Do not climb today or tomorrow — the rock has been repeatedly wetted over the past three days and internal moisture levels will be dangerously high, risking permanent hold breakage on Kyloe's delicate pocket features.
- The surface may appear dry before the interior has dried — a dry-looking surface does not mean the rock is safe to climb on porous Fell Sandstone.
Reasoning
With 13.3mm on Aug 19, 2.3mm on Aug 20, and 0.8mm today, plus 26mm total in the last 7 days at 79% average humidity, the rock is almost certainly still damp internally despite any surface drying.
The SW aspect helps when sunny, but temperatures have been cool (14°C average over 7 days), humidity high (79%), and wind moderate — effective drying has been minimal with zero consecutive dry days since the heavy rain on the 19th.
Fell Sandstone loses 80% of its compressive strength within hours of wetting, and the repeated wetting cycle over the past week means the small iron-oxide-cemented holds and pockets at Kyloe are at genuine risk of breakage.
Late August should offer reasonable drying conditions, but the current spell is unseasonably cool and damp for summer, reducing the expected drying advantage of the season.
Contributing Factors
6
13.3mm fell on Aug 19 with further rain on the 20th (2.3mm) and today (0.8mm), repeatedly re-saturating the rock with no dry window for recovery.
There have been no consecutive dry days since the significant rain on Aug 19, falling well short of the minimum 1–2 dry days the crag requires.
Average humidity of 79% over the last week severely limits evaporative drying, meaning even rain-free hours contribute little to drying.
Average temperatures of only 14°C over the past week are well below summer norms, slowing evaporation and internal drying rates.
The south-west facing aspect receives good solar radiation when the sun is out, and post-canopy-loss air circulation is improved, aiding surface drying.
78.7mm of rain over the past 28 days means the rock has had limited opportunity to fully dry out at depth, even during the brief dry spell of Aug 10–15.
Recommendations
3
- Wait for at least 2 full consecutive dry days before visiting — the earliest realistic window is August 24 if conditions hold dry from the 22nd.
- If visiting on the 24th or 25th, chalk-test pockets and horizontal features before committing to problems, and avoid lower sections of the crag where drainage accumulates.
- Check for seepage from above, particularly where the old tree line was — water can track through the soil and emerge on the upper crag face days after rain.

Kyloe-in-the-Woods received significant rain today (7.6mm) on top of 12.3mm yesterday, following a wet week totalling nearly 30mm. The rock will be thoroughly saturated and needs multiple dry days to recover — climbing today or tomorrow would risk hold breakage on the pocket-rich Fell Sandstone.
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 shelter that reduces wind-driven drying at rock level — pockets and horizontal features will hold moisture longer than the surface suggests.
- Steep pocket-rich rock is characteristic of Kyloe and these concave features trap water and dry much slower than vertical faces; a chalk test on pockets is essential before committing to any problem.
- Seepage from above remains a known issue at this crag — the condition report from March 2026 specifically notes checking for seepage even on otherwise dry-looking days.
- The recent pattern of repeated wetting events (12.3mm on Aug 19, 7.6mm today, 7mm on Aug 17, 6.5mm on Aug 9) means the rock has had no sustained drying window and internal saturation will be high.
Warnings
2
- Fell Sandstone loses up to 50% of its compressive strength when wet — climbing on saturated pockets risks permanent, irreversible hold breakage.
- The surface may appear dry before the interior has adequately dried; always perform a chalk test on key holds, especially in pockets and horizontal breaks.
Reasoning
With 12.3mm yesterday and 7.6mm today (most falling overnight/early morning), plus 7mm on Aug 17 and scattered showers throughout the past week, the rock is certainly saturated well beyond the critical 1% threshold where significant strength loss begins.
The SW aspect would normally aid drying, but today's 100% cloud cover, moderate temperatures (~13-14°C), and humidity around 75-82% severely limit evaporation — and tomorrow brings another 3.1mm of rain, resetting any drying progress.
At current saturation levels the Fell Sandstone will have lost 30%+ of its compressive strength, making the small iron-oxide-cemented pockets and crimps that define Kyloe's climbing highly vulnerable to breakage under load.
Mid-August temperatures are adequate for drying when dry weather arrives, but the recent pattern of frequent rain events has kept the rock in a near-continuously wet state, preventing the cumulative drying that summer conditions would normally provide.
Contributing Factors
6
19.9mm fell in the last two days alone (12.3mm on Aug 19, 7.6mm today), with no intervening dry period, ensuring deep saturation of the porous sandstone.
The current count of consecutive dry days is zero, and the rock has been repeatedly re-wetted over the past week with no sustained drying window.
The forecast for Aug 21 includes 3.1mm of additional precipitation, which will reset any drying progress that might occur later today.
Northerly winds of 20-26 km/h through the afternoon will help surface evaporation, though the partially sheltered woodland setting limits this benefit at crag level.
Temperatures of 13-14°C are sufficient for evaporation, though cooler than the seasonal average and not enough to overcome the high humidity and ongoing moisture input.
Average humidity over the past 7 days is 78%, with today peaking near 98% overnight, significantly slowing the evaporation rate from the rock surface.
Recommendations
3
- Do not climb today — the rock is wet from overnight rain and deeply saturated from the past week's repeated precipitation.
- The earliest realistic window opens Aug 23 after two full dry days, but a visual inspection and chalk test on pockets should be performed before climbing.
- If visiting later this week, prioritise the steepest overhanging faces which shed water fastest, and avoid any areas with visible seepage from above.

Today has seen light rain through the early morning and more is forecast this afternoon/evening, adding to 7mm on the 17th, 0.6mm on the 18th, and a broadly unsettled recent pattern with 12.8mm in the last 7 days. The rock will not have had adequate drying time and should not be climbed today; conditions should improve from the 21st onward as a dry spell establishes.
Based on weather conditions only — does not cover bird nesting restrictions or other access issues.
- The woodland canopy loss from 2020 felling and Storm Arwen means the crag now dries faster than older guides suggest, but the remaining shelter still reduces wind-driven evaporation at the rock face.
- Steep pocket-rich rock is characteristic of Kyloe and pockets hold moisture longer than open faces — a dry-looking wall can still have damp pockets that are load-bearing for climbers.
- Seepage from above remains an issue even after moderate rain; the condition report from March 2026 specifically advises checking for seepage and chalk-testing holds.
- The 28-day total of 65.5mm across a frequently interrupted drying pattern means background moisture levels in the rock are elevated for summer — extra caution warranted despite warm temperatures earlier in the period.
Warnings
2
- 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 before the interior has dried adequately; pockets and horizontal features trap moisture longer than vertical faces.
Reasoning
Rain today (3.2mm total forecast), following 7mm on the 17th and 0.6mm on the 18th, means the rock is currently wet both externally and internally with no meaningful drying window since the last significant rainfall.
The SW aspect and partial wind exposure would normally aid drying, but today's light winds (7–12 km/h), high humidity (84%), and overcast skies provide minimal evaporative potential; meaningful drying cannot begin until tomorrow at the earliest.
With repeated wetting events over the past two weeks (65.5mm in 28 days) and no extended dry spell, internal moisture levels are elevated, increasing the risk of hold breakage on the pocket-dependent Fell Sandstone.
Mid-August temperatures (14–17°C) are adequate for drying but not exceptional, and the recent pattern of showers every 2–3 days has prevented the rock from fully drying out between events.
Contributing Factors
7
Light rain fell this morning (0.8mm by 06:00) with further showers forecast this afternoon totalling ~3.2mm for the day, on top of 0.6mm yesterday — the rock is actively being wetted.
7mm on Aug 17, 6.5mm on Aug 9, 7.3mm on Aug 4, and 31.4mm on Jul 26 mean the rock has been repeatedly saturated with no sustained drying period longer than 4–5 days in the last month.
65.5mm over 28 days with frequent interruptions to drying means background pore saturation is likely well above the threshold where strength loss begins.
Humidity averaging 84% today with peaks to 95% severely limits evaporative drying from the rock surface.
A sustained dry spell is forecast from Aug 21 onward with declining humidity (69–72%) and moderate winds, which should allow progressive drying over the next several days.
The south-west facing aspect will receive good solar radiation when skies clear, and the reduced canopy from Storm Arwen improves air circulation for drying.
Temperatures of 14–18°C over the coming days are adequate but not exceptional for driving evaporation from porous sandstone.
Recommendations
3
- Do not climb today — the rock is actively wet from ongoing rain and has had no drying time since the last precipitation.
- The earliest reasonable opportunity is August 22nd after two full dry days, but assess conditions carefully on arrival, especially in pockets and at the base of the crag.
- Use the chalk test on holds before committing to any problem — if chalk darkens or absorbs immediately, the rock is still too damp to climb safely.

The rock received 4.5mm of rain overnight/early morning today (18 Aug), following 2.0mm on the 16th and 4.2mm on the 17th — a cumulative 10.7mm over the last three days with zero consecutive dry days. Even though the afternoon is forecast dry with decent wind, the porous Fell Sandstone will still be internally saturated and climbing today or tomorrow would risk hold damage on this pocket-rich rock.
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 slows wind-driven drying compared to fully exposed crags.
- Steep pocket-rich rock at Kyloe holds moisture in horizontal features and slots — these micro-reservoirs take significantly longer to dry than flat faces.
- The SW aspect helps with afternoon solar gain, but today's 100% cloud cover negates much of that benefit, and the recent canopy loss means seepage from above is now more of a factor after rain.
- The most recent condition report (March 2026) explicitly advises chalk-testing for seepage from above, confirming that drainage from the hillside above remains an ongoing concern even in apparently dry spells.
Warnings
2
- Climbing on saturated Fell Sandstone risks permanent, irreversible hold breakage — the pocket-rich features at Kyloe are especially vulnerable.
- The forecast shows no meaningful dry window in the next 5 days; do not assume the rock will dry between showers.
Reasoning
The rock has received rain on three of the last three days (2.0mm, 4.2mm, 4.5mm) totalling 10.7mm, with no dry days to allow any meaningful drying — the sandstone will be thoroughly wet internally despite any surface drying this afternoon.
Although this afternoon brings moderate westerly winds (~25 km/h) and dropping humidity (~60%), the SW-facing rock under full cloud cover will achieve only surface evaporation at best; internal drying of porous Fell Sandstone after 10.7mm cumulative rain requires at least 48 hours of dry weather.
At current saturation levels the sandstone will have lost 30%+ compressive strength, and the characteristic small iron-oxide pockets and holds at Kyloe are especially vulnerable to breakage under load.
Mid-August temperatures (~17°C) support reasonable evaporation rates when dry weather arrives, but the current unsettled spell with rain forecast through to the 23rd means conditions will not improve soon.
Contributing Factors
7
10.7mm over the last 3 days (16th–18th) with zero consecutive dry days means the rock is thoroughly saturated.
4.5mm fell overnight into the early hours, with the last rain at 02:00; the rock has had fewer than 16 hours of partial drying at best.
Moderate westerly wind (~25 km/h) and humidity dropping to ~59% this afternoon will begin surface drying, but this is insufficient for internal drying.
100% cloud cover forecast all day eliminates direct solar radiation on the SW face, significantly reducing evaporative drying.
3.9mm forecast for the 19th will re-wet any surface drying achieved today, resetting the drying clock.
Kyloe's steep pocket and slot features trap water and take longer to drain and dry than smooth faces.
Despite reduced canopy, the woodland setting still limits airflow at rock level, slowing drying compared to exposed crags.
Recommendations
3
- Do not climb today — the rock is wet from overnight rain and internally saturated from three consecutive days of precipitation.
- The forecast shows rain on each of the next five days; monitor conditions and plan for the first window of 48+ consecutive dry hours before visiting.
- When you do visit after a dry spell, use the chalk-touch test on pockets and check for seepage lines from above before committing to problems.

Rain today (3.7mm with heavier falls forecast this evening) follows rain yesterday (2.0mm on Aug 16), and the forecast shows continued wet weather through Aug 21. The rock is currently wet and will not have adequate drying time in the coming days.
Based on weather conditions only — does not cover bird nesting restrictions or other access issues.
- Post-canopy loss (2020 felling + Storm Arwen 2021) means the crag dries faster than older guides suggest, but the woodland setting still provides shelter that limits wind-driven drying, and the steep pocket-rich rock traps moisture in horizontal features.
- The 28-day precipitation total of 58.4mm indicates the sandstone has had repeated wetting events throughout late July and early August, meaning background moisture levels in the rock are elevated beyond what individual rain events suggest.
- Seepage from above remains a concern at Kyloe — the condition report from March 2026 specifically notes checking for seepage and chalk-testing when in doubt, which is especially relevant after multi-day wet spells.
- The SW aspect would normally aid drying, but today's high cloud cover (80–100% from midday), high humidity (75–82%), and light winds (~10–12 km/h) severely limit solar-driven evaporation.
Warnings
2
- Climbing on wet Fell Sandstone causes permanent, irreversible damage to the small iron-cemented holds that define Kyloe's boulder problems.
- The rock surface may appear dry between showers while the interior remains saturated — do not be deceived by brief dry spells during this unsettled period.
Reasoning
The rock is currently wet from today's 3.7mm of rain (with 2.4mm forecast in the final hour alone), compounded by 2.0mm yesterday and 7.3mm on Aug 4, with no consecutive dry day stretch exceeding 5 days in the past month.
Despite the SW aspect, today's light winds (8–12 km/h), high humidity (75–97%), and near-total cloud cover provide minimal drying; the heavier rain forecast this evening will reset any partial drying that occurred during the day.
Fell Sandstone loses up to 50% of its compressive strength when wet, and the steep pocket-dependent climbing at Kyloe makes hold integrity critical — climbing on inadequately dried rock risks permanent damage to the small iron-cemented holds.
Summer temperatures (~16–17°C) would normally support reasonable drying, but the current unsettled pattern with repeated rain events and above-average humidity is preventing the rock from drying adequately between showers.

3.7mm recorded today with the heaviest falls (2.4mm) forecast in the final hours, fully wetting the rock surface and pore structure.
Rain on Aug 16 (2.0mm), Aug 9 (6.5mm), Aug 6 (1.8mm), and Aug 4 (7.3mm) means the sandstone has been repeatedly saturated with no extended drying window.
Humidity averaging 71% over the past week with today peaking at 95–97% severely restricts evaporative drying from the rock surface.
Rain is forecast on each of the next four days (Aug 18–21, totalling 16.6mm), eliminating any meaningful drying window until at least Aug 22.
The SW aspect and partial wind exposure would normally aid drying, but persistent cloud cover and continued rainfall negate these advantages entirely.
Temperatures of 14–17°C are warm enough to support reasonable drying rates once rain stops, but they cannot overcome active precipitation.
Recommendations
3
- Do not climb today or in the coming days — the rock is actively wet and the forecast offers no drying window until Aug 22 at the earliest.
- Monitor conditions from Aug 22 onwards: if the dry spell holds and Aug 23 is also dry, an assess-conditions visit on Aug 23 may be viable with careful chalk-testing of holds.
- When you do visit, check for seepage from above and test suspect holds with chalk dust before committing — pockets and horizontal features at Kyloe hold hidden moisture long after the face appears dry.

Today has seen 1.4mm of rain, and the forecast shows continued wet weather through to August 20th, with no meaningful dry window expected until August 21st at the earliest. The rock is likely damp now and will not get a chance to dry over the coming days.
Based on weather conditions only — does not cover bird nesting restrictions or other access issues.
- The woodland setting, despite canopy loss since 2020/Storm Arwen, still provides enough shelter to slow wind-assisted drying — the partial exposure means pockets and lower sections will hold moisture longer than open crags.
- Kyloe's steep, pocket-rich Fell Sandstone traps water in horizontal features and solution pockets; these act as small reservoirs that extend internal drying times well beyond what the surface suggests.
- The condition notes specifically warn against relying on the old 'perma-dry' reputation — the crag's changed canopy means it now gets wetter than historic accounts imply, and at least 1–2 full dry days are required after rain.
- The most recent condition report (March 2026) confirms that seepage from above remains a live concern and recommends chalk-testing holds even when conditions appear broadly dry.
Warnings
2
- Fell Sandstone loses significant strength at very low moisture levels — even if the surface feels dry, internal saturation from recent rain makes hold breakage a real risk.
- Pockets and horizontal features will hold standing water that is not visible from below; test with chalk before pulling on any hold.
Reasoning
Today's 1.4mm of rain follows a pattern of intermittent showers over recent weeks (7.3mm on Aug 4, 6.5mm on Aug 9), and while there was a good dry spell from Aug 10–15, today's rain has re-wetted the surface and pockets.
The SW aspect and moderate wind would normally allow reasonable drying within 24–48 hours after light rain, but the forecast shows further rain tomorrow (2.7mm) and on subsequent days, preventing any effective drying window from opening.
Repeated wetting cycles over recent weeks (31.4mm on July 26, multiple smaller events since) mean the deeper rock has had limited opportunity to fully dry internally, and climbing on re-wetted pockets risks hold breakage on these iron-oxide-cemented features.
Mid-August temperatures are adequate for drying (~17–20°C), but the unsettled Atlantic pattern delivering frequent showers is typical of a Northumberland summer and is preventing sustained dry conditions.

1.4mm fell today with 2.7mm forecast tomorrow and further rain through August 20th, giving zero consecutive dry days for effective drying.
Multiple rain events over the past three weeks (31.4mm on Jul 26, 7.3mm on Aug 4, 6.5mm on Aug 9) have kept the deeper rock from fully drying despite intervening dry spells.
The south-westerly aspect and mid-August temperatures (17–20°C) provide good solar heating and would support rapid drying if a sustained dry window opened.
Partial wind exposure with 13–17 km/h winds aids surface evaporation, though the residual woodland shelter limits airflow at rock level.
The steep, pocket-heavy climbing style means water collects in horizontal features that dry more slowly than flat faces, extending the effective drying period.
Humidity at 77% today and forecast at 85% tomorrow significantly slows evaporative drying from the rock surface.
Recommendations
3
- Do not climb today or over the next few days — the forecast shows continued rain through August 20th with no adequate drying window.
- Target August 22nd or later if the dry weather from August 21st holds, but check conditions on arrival with a chalk test on holds before committing.
- If visiting the area during this wet spell, consider non-porous alternatives such as the Whin Sill crags (Great Wanney, Crag Lough) which can be climbed when dry on the surface.
