Bowden Doors is clearly too wet to climb today. The past two weeks have seen over 50mm of rain with no meaningful dry spell — the last significant rain was yesterday (6.6mm on June 11), and further light rain fell on June 12–16 with today recording 1.4mm. The rock will be saturated internally despite any surface drying, and the forecast offers no dry window in the coming days.
Based on weather conditions only — does not cover bird nesting restrictions or other access issues.
- The bird nesting restriction (June 1 – July 30) is currently active and may limit access to certain sections of the crag — check BMC RAD for specific affected routes before visiting.
- Upper tier seepage at Bowden Doors persists longer than the lower boulders after prolonged wet periods; given 52mm in the last 28 days, expect seepage lines on upper routes even when lower sections feel dry.
- The exposed WSW hilltop position and recent strong SW/W winds (30–40 km/h on several days) are the best drying asset this crag has, but humidity has averaged 79% over the past week, significantly limiting evaporative drying.
- The cumulative rainfall pattern (34+ mm from June 1–11 alone, with no consecutive dry spell longer than 2 days) means internal saturation is likely well above the critical threshold despite brief dry intervals.
Warnings
3
- Fell Sandstone loses up to 50% of its compressive strength when wet — climbing now risks permanent hold breakage and irreversible route damage.
- The rock surface may appear dry during afternoon hours but internal saturation after weeks of rain means holds are significantly weakened.
- Bird nesting restriction is currently active (June 1 – July 30); some routes may be closed regardless of conditions.
Reasoning
With 52mm of rain over the past 28 days and 10.2mm in the last 7 days alone — including 6.6mm on June 11 and further light precipitation on June 15–16 — the porous Fell Sandstone is almost certainly saturated internally, with zero consecutive dry days recorded.
Although the exposed SW/W aspect and moderate winds (20–40 km/h) favour surface drying, average humidity of 79% and persistent cloud cover have severely limited evaporative drying, and the longest dry gap in the past two weeks was only 2 days (June 12–13) — far short of the 2–3 days needed after heavy rain.
Internal moisture levels are likely very high given the cumulative 34mm from June 1–11 with no adequate drying window; climbing now risks significant hold breakage and grain loosening on these iron-oxide cemented holds.
Mid-June temperatures (12–18°C) are reasonable for drying but the current unsettled Atlantic pattern with persistent humidity and frequent showers is preventing the sustained dry spell needed to bring the sandstone into safe condition.
Contributing Factors
6
Over 52mm in 28 days with 34mm from June 1–11 and further rain on June 15–16 means cumulative saturation with no adequate drying window.
Today has recorded 1.4mm of precipitation and the last fully dry day was June 14, providing only a 2-day dry gap before further rain on June 15.
Average humidity of 79% over the past week with today peaking at 97% severely limits evaporative drying from rock surfaces.
Strong winds of 20–40 km/h from SW/W on several recent days provide the best available drying mechanism for this crag.
The WSW-facing escarpment benefits from afternoon solar radiation, though 100% cloud cover today negates this advantage.
The next 5 days forecast an additional 11.4mm of rain with no consecutive dry days, preventing any meaningful drying.
Recommendations
3
- Do not climb at Bowden Doors today or in the coming days — the rock is too wet internally and the forecast offers no adequate drying window.
- Monitor conditions for a sustained dry spell of at least 3 full days with low humidity before considering a visit, given the cumulative saturation from the past fortnight.
- Remember that the bird nesting restriction is active (June 1 – July 30) — check the BMC RAD for which routes are affected before planning any trip.

Bowden Doors has experienced a very wet period with 52mm over the past 28 days and significant rain on June 1–4 and again on June 8–11, followed by only three dry days (June 12–14) before today's light rain resets the drying clock. The rock is almost certainly still holding internal moisture from this prolonged wet spell, and the forecast shows continued intermittent rain through to June 20, offering no adequate drying window.
Based on weather conditions only — does not cover bird nesting restrictions or other access issues.
- The upper tier at Bowden Doors is known to have persistent seepage lines that take longer to dry than the lower boulders, even in otherwise favourable conditions.
- The bird nesting restriction (June 1 – July 30) is currently active and may limit access to certain sections of the crag — check the BMC RAD for specific route closures.
- Bowden's exposed hilltop position and SW/W aspect are significant drying advantages, but the cumulative 52mm over 28 days means even this well-positioned crag will be holding internal moisture.
- The lower boulder problems at the base of the escarpment tend to stay wetter longest due to downward drainage through the porous sandstone.
Warnings
3
- Fell Sandstone loses up to 50% of its compressive strength when wet — climbing on damp rock risks permanent hold breakage and irreversible route damage.
- The rock surface may appear dry while the interior remains saturated; do not rely on surface appearance alone after this prolonged wet period.
- Bird nesting restriction is currently active (June 1 – July 30) — some routes or sections may be closed.
Reasoning
With 34.2mm of rain in the first two weeks of June (including 10.6mm on June 2 and 10.1mm on June 4), only three consecutive dry days (June 12–14) before today's renewed rain, and high average humidity of 77%, the rock is very likely still holding significant internal moisture despite possible surface drying.
The three dry days from June 12–14 with strong winds (31–39 km/h) and the SW/W aspect would have begun surface drying, but this is insufficient to clear the deep moisture from the prolonged wet period; today's 1.5mm and forecast rain through June 20 will continually replenish surface moisture.
Given the cumulative moisture loading over the past month (52.3mm), the porous Fell Sandstone is likely at elevated saturation levels internally, posing real risk of hold breakage and grain loosening — significant weakening begins at only ~1% saturation.
Mid-June temperatures (averaging ~11°C) are moderate but not warm enough to drive rapid deep drying, and the persistent high humidity (77–89%) substantially slows evaporation rates.
Contributing Factors
7
52.3mm over 28 days with heavy clusters on June 1–4 (34.2mm) and June 8–11 (13.7mm) means deep moisture saturation of the porous sandstone.
Only three consecutive dry days (June 12–14) occurred before today's rain, well short of the 2–3+ dry days needed after heavy rain on already-saturated rock.
1.5mm today (mostly late evening) adds surface moisture and prevents any continued drying progress from the June 12–14 window.
The next five days show daily precipitation of 0.4–4.2mm with humidity of 78–89%, offering no meaningful drying window.
Bowden's hilltop exposure and consistent 17–41 km/h winds over recent days provide above-average surface drying potential when rain pauses.
The favourable south-west/west aspect receives good afternoon solar radiation in June, aiding surface evaporation during dry spells.
Average humidity of 77% over the last week and 87–89% forecast for the next two days substantially reduces net evaporation from the rock surface.
Recommendations
3
- Do not climb today or in the coming days — the rock needs a sustained dry period of at least 3–4 days given the cumulative moisture from recent weeks.
- Check the BMC RAD for active bird nesting restrictions at Bowden Doors (June 1 – July 30) before planning any visit.
- When conditions finally improve, test the base of the crag for dampness — if soil at the base is not sandy-dry, the rock is still holding internal moisture.

After a very wet period (34.2mm from June 1–11), Bowden Doors has had three dry days with good wind exposure, but the cumulative moisture loading from the preceding fortnight means internal dampness may persist, particularly in seepage zones. The exposed SW aspect and strong winds are helping, but 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 upper tier at Bowden Doors is known for persistent seepage lines that can remain wet long after the lower boulders have dried, especially after the kind of prolonged wet spell seen from June 1–11.
- Bird nesting restriction is active (June 1 – July 30) and may limit access to certain sections of the crag — check BMC RAD for current closures before visiting.
- The exposed hilltop position and prevailing SW winds have been working hard over these three dry days, but average temperatures have been cool (11–14°C) which slows evaporation from the interior.
- The 50.8mm of rain in the last 28 days represents significant cumulative moisture loading for Fell Sandstone — the rock may appear surface-dry while retaining internal moisture that weakens holds.
Warnings
2
- The rock surface may appear dry while the interior remains weakened — test holds carefully and retreat if any dampness is detected.
- Bird nesting restriction is active until July 30; some routes or sections may be off-limits.
Reasoning
Heavy rainfall totalling ~34mm fell between June 1–4, followed by intermittent light showers through June 11 (another ~14mm), meaning the rock has been repeatedly re-wetted with only brief partial drying intervals — internal saturation is likely still elevated despite three dry days.
Three consecutive dry days with strong winds (22–39 km/h from W/NW) and a SW aspect have provided reasonable drying conditions, but cool temperatures (12–17°C) and moderate humidity (70–78%) have limited the drying rate; this is borderline for the 2–3 dry days guideline given the severity of prior wetting.
Given the cumulative 50.8mm over 28 days with repeated wetting cycles, internal moisture levels may still be above the threshold where significant strength loss occurs — hold breakage risk is moderate, particularly on well-trafficked problems.
Early summer conditions are improving but temperatures have been below seasonal average; no freeze-thaw risk exists, but the prolonged wet spring means background moisture levels in the rock are likely elevated.
Contributing Factors
7
34mm fell June 1–4 with further showers through June 11, deeply saturating the porous Fell Sandstone over an extended period.
No rain since June 11, giving three full days of drying which partially meets the 2–3 day guideline for heavy rain.
Winds of 22–40 km/h from favourable directions (W, SW, NW) have significantly aided surface and near-surface drying.
Average temperatures of only 11–14°C over the last week are below the seasonal norm, slowing evaporation from deeper within the rock.
Humidity averaging 76% over the last seven days reduces the vapour pressure gradient and slows drying.
The WSW-facing escarpment receives afternoon solar radiation which aids surface drying, though recent cloud cover may have reduced direct sun.
50.8mm over 28 days with repeated wetting cycles means the rock has rarely fully dried out, keeping background saturation elevated.
Recommendations
3
- Visit and visually assess conditions on arrival — check the base of the crag for damp ground and feel the rock surface in shaded spots before climbing.
- Prioritise exposed, overhanging, and lower-tier boulder problems which dry fastest; avoid the upper tier where seepage lines are known to persist.
- Check BMC RAD for current bird nesting restrictions (June 1 – July 30) before travelling, as certain sections may be closed.

The last significant rain was 6.6mm on June 11, just two days ago, following a very wet 10-day period that deposited over 50mm. While today's strong westerly winds (39 km/h) and the exposed hilltop position will have accelerated drying, the cumulative saturation from repeated rainfall events means internal moisture likely persists, particularly in sheltered areas and seepage zones.
Based on weather conditions only — does not cover bird nesting restrictions or other access issues.
- The prolonged wet spell from June 1–11 deposited ~50mm across multiple events, meaning the sandstone has been repeatedly re-saturated with little chance to dry internally between showers.
- Upper tier seepage lines at Bowden Doors are known to persist longer than the lower boulders — even if the main face looks dry, water can weep from above for days after heavy cumulative rain.
- The bird nesting restriction (June 1 – July 30) is currently active and may limit access to certain sections of the crag.
- The strong SW/W winds today and yesterday are directly hitting the crag face, which is the single most favourable drying factor at play — but two days of wind cannot fully compensate for 10+ days of repeated soaking.
Warnings
2
- Bird nesting restriction is currently active (June 1 – July 30) — check which sections are affected before visiting.
- The rock surface may appear dry while internally weakened — do not trust surface appearance alone after this volume of cumulative rain.
Reasoning
The rock has been subjected to repeated wetting events totalling ~50mm over 10 days (June 1–11), with only two fully dry days since — internal moisture levels are likely still elevated despite surface drying.
Strong westerly winds (31–40 km/h) directly hitting the SW/W-facing crag over the last two dry days provide excellent surface drying, but the cumulative saturation depth from prolonged rain means deeper pore moisture will take longer to dissipate.
Given the high porosity of Fell Sandstone and repeated saturation over the past fortnight, internal weakening of holds is a real concern — the rock may feel dry on the surface while retaining enough moisture to reduce compressive strength by 10–30%.
Early June temperatures (~12–18°C) are moderate and adequate for drying, but humidity has remained elevated (70–87%) through the wet spell, slowing evaporation rates.
Contributing Factors
6
Over 50mm of rain fell across multiple events from late May through June 11, repeatedly re-saturating the porous sandstone before it could fully dry.
Two days of strong SW/W winds (31–40 km/h) hitting the crag face directly provide excellent surface evaporation and are the primary favourable drying factor.
The guideline of 2–3 dry days after heavy rain is a minimum, and the cumulative saturation from 10+ days of rain warrants the longer end of that range or beyond.
Humidity has averaged ~76% over the last week, reducing the vapour pressure gradient and slowing evaporative drying despite the wind.
Temperatures of 14–18°C are adequate for evaporation, though not high enough to drive rapid deep drying of saturated sandstone.
Bowden Doors' exposed 170m hilltop setting maximises airflow across all faces, giving it better drying characteristics than sheltered woodland crags.
Recommendations
3
- Wait at least one more full dry day (until June 14) before climbing, and then perform a careful visual and touch assessment of the rock surface — check the base of the crag for residual dampness.
- Avoid the upper tier entirely for now, as seepage lines are likely still active after the prolonged wet period.
- Check the current bird nesting restriction status (June 1 – July 30) and respect any access closures on affected sections.

Bowden Doors received 6.6mm of rain yesterday (June 11) and has had only one dry day since, following a very wet 10-day period totalling over 34mm. Despite today's strong westerly winds and lower humidity, the porous Fell Sandstone is almost certainly still holding significant internal moisture and needs more drying time.
Based on weather conditions only — does not cover bird nesting restrictions or other access issues.
- The prolonged wet spell from June 1–11 (~50mm over 11 days with only brief dry breaks) will have deeply saturated the rock, meaning surface dryness today is misleading — internal moisture levels are likely still very high.
- Upper tier seepage lines at Bowden Doors are known to persist longer than the lower boulders after sustained wet periods; expect weeping on upper routes even if lower problems appear dry.
- Bird nesting restriction is active (June 1 – July 30) — check BMC RAD for which specific sections are affected before planning a visit.
- The exposed hilltop position and today's strong 30 km/h westerly wind onto the SW/W-facing rock is helping surface drying, but capillary moisture from the prolonged saturation period will take considerably longer to clear.
Warnings
3
- The rock surface may appear dry while the interior remains saturated — do not be deceived by surface appearance after such a prolonged wet period.
- Climbing on internally wet Fell Sandstone risks permanent hold breakage and irreversible route damage; the iron oxide holds are particularly fragile when moisture is present.
- Bird nesting restriction (June 1 – July 30) is active — verify which areas are accessible via the BMC RAD before travelling.
Reasoning
The rock has been subjected to repeated wetting events over the past 11 days (~34mm from June 1–11, with only isolated dry days that were insufficient for meaningful drying), leaving the sandstone deeply saturated well beyond the critical 1% threshold where significant weakening begins.
Only one full dry day has elapsed since the last rain (6.6mm on June 11), and while today's 30 km/h westerly wind and 70% humidity are favourable for surface evaporation, the cumulative saturation from the prolonged wet period means the interior of the rock will need at minimum 2–3 more dry days to approach safe moisture levels.
With deep internal saturation from repeated heavy rain events, the risk of hold breakage and grain loosening is high — compressive strength is likely reduced by 30%+ and iron oxide cemented holds are particularly vulnerable.
Early June temperatures (averaging 11.3°C over the past week) are cooler than ideal for rapid drying, and the active bird nesting restriction (June 1 – July 30) may further limit accessible sections of the crag.
Contributing Factors
7
Over 34mm fell between June 1–11 with only brief dry interruptions, deeply saturating the porous Fell Sandstone far beyond surface-level moisture.
A single dry day after 6.6mm of rain (and a prolonged wet spell) is far short of the 2–3 dry days minimum required for Bowden Doors even in good drying conditions.
Today's 30 km/h westerly wind blowing directly onto the SW/W-facing crag is actively accelerating surface evaporation.
Humidity has dropped to 70% today from 87% yesterday, improving evaporation rates at the rock surface.
Repeated wetting over 10+ days allows moisture to penetrate far deeper than a single rain event, requiring substantially longer drying times than the standard 2–3 day guideline.
The 7-day average of 11.3°C is below ideal for rapid evaporative drying of deeply saturated sandstone.
The June 1 – July 30 bird nesting restriction is currently in effect, which may limit access to certain sections of the crag.
Recommendations
3
- Do not climb today — the rock has had only one dry day after a prolonged wet spell and is almost certainly still dangerously damp internally.
- If the forecast dry spell holds through June 13–14, reassess conditions on-site on June 14 by checking for moisture at the crag base and on sheltered faces before committing to climb.
- Check the BMC RAD for current bird nesting restrictions before visiting, as sections of the crag may be closed until July 30.

Bowden Doors is currently receiving heavy rain today (8.5mm forecast) on top of a very wet recent period — over 16mm in the last 7 days and 52.8mm in the last 28 days. The porous Fell Sandstone will be thoroughly saturated and needs at minimum 2–3 full dry days before climbing is appropriate.
Based on weather conditions only — does not cover bird nesting restrictions or other access issues.
- The bird nesting restriction (June 1 – July 30) is currently active and may limit access to certain sections of the crag — check BMC RAD for specific closures before visiting.
- Upper tier seepage lines at Bowden Doors persist longer than the lower boulders after prolonged wet spells; the recent 10-day wet period means seepage could linger well beyond when surfaces appear dry.
- The exposed WSW hilltop position and forecast strong westerly winds (31–39 km/h) over the next two days will significantly aid surface drying, but internal moisture from cumulative saturation will take longer to dissipate.
- The repeated wetting cycles from late May through today (rain on 8 of the last 12 days) mean deep saturation levels are high — surface-dry appearance will be misleading for several days.
Warnings
3
- Fell Sandstone loses up to 50% of its compressive strength when wet — climbing now risks permanent hold breakage and irreversible route damage.
- The rock surface may appear dry well before the interior has adequately dried; do not rely on visual assessment alone after this prolonged wet spell.
- Bird nesting restriction is active (June 1 – July 30) — verify permitted areas via BMC RAD before climbing.
Reasoning
The rock is thoroughly saturated after repeated rainfall events totalling over 35mm since June 1 alone, with 8.5mm falling today; internal moisture levels will be at or near critical saturation.
Despite the exposed SW aspect and strong forecast winds (31–39 km/h W) from tomorrow, the cumulative deep saturation from nearly two weeks of intermittent rain means meaningful internal drying will require at least 48–72 hours of dry weather.
At current saturation levels, Fell Sandstone will have lost 30%+ of its compressive strength, creating serious risk of hold breakage and permanent route damage — iron oxide holds are especially vulnerable.
Early June temperatures (12–16°C) and moderate humidity (65–70% forecast) provide reasonable but not exceptional drying conditions; the active bird nesting restriction (June 1 – July 30) is an additional access consideration.
Contributing Factors
7
8.5mm of rain is falling today, mostly between 10:00–16:00, directly saturating the rock surface and replenishing deep moisture.
Over 35mm has fallen since June 1 across multiple events, keeping the porous sandstone in a near-continuously saturated state with no adequate drying window.
Average humidity of 78% over the last 7 days and 87% on rain days has severely limited evaporative drying between showers.
Forecast westerly winds of 31–39 km/h on June 12–13 will significantly accelerate surface drying once rain stops.
The WSW-facing hilltop position maximises afternoon solar exposure and wind contact, giving Bowden Doors above-average drying potential for Fell Sandstone.
Only 0.3mm of precipitation is forecast over the next 6 days, providing the sustained dry window needed for recovery.
The June 1 – July 30 bird nesting restriction is currently active and may limit access to parts of the crag.
Recommendations
3
- Do not climb today or tomorrow — the rock is saturated and structurally compromised; wait for a minimum of 2–3 full dry days.
- Check the BMC RAD for current bird nesting restriction details before planning a visit during the June 1 – July 30 period.
- When you do visit, test the ground at the crag base — if it is damp rather than sandy-dry, the rock interior is still too wet to climb safely.

Bowden Doors is currently saturated and unsafe for climbing. The past 10 days have seen over 40mm of rain with very few dry intervals, today has added further precipitation, and the rock will be thoroughly wet internally despite its exposed position. Rain is forecast to continue through June 11, with the earliest realistic drying window beginning June 12.
Based on weather conditions only — does not cover bird nesting restrictions or other access issues.
- The upper tier at Bowden Doors is known to hold seepage longer than the lower boulders, so even when the lower problems feel dry the upper routes may still be weeping.
- The bird nesting restriction (June 1–July 30) is now active and may limit access to certain sections of the crag — check the BMC RAD for current closures before visiting.
- Bowden's exposed hilltop position and SW/W aspect are significant advantages for drying, but cannot compensate for the cumulative soaking the rock has received over the past 10 days.
- The prolonged wet spell (34mm from June 1–4 alone) will have driven moisture deep into the porous Fell Sandstone; surface drying will outpace internal drying, creating the most dangerous scenario for hold breakage.
Warnings
2
- Climbing on saturated Fell Sandstone risks permanent, irreversible hold breakage — the rock may appear surface-dry while retaining dangerous internal moisture.
- Bird nesting restriction is active (June 1–July 30); certain routes or sections may be closed.
Reasoning
The rock has received approximately 43mm of rain since May 30, including 34mm in just four days (June 1–4), with further light rain on June 6, 8, and today (June 9) — the Fell Sandstone will be deeply saturated well beyond the critical 1% threshold.
Although the SW/W aspect and exposed position with consistent 20–30 km/h winds aid drying, there has been virtually no consecutive dry period since the heavy rain began on June 1; brief dry intervals of 12–24 hours between showers are nowhere near sufficient to dry porous sandstone.
With deep internal saturation from cumulative heavy rain, the rock is likely at 30–50% strength reduction; climbing now risks permanent hold breakage and grain loosening on this irreplaceable crag.
Early June temperatures (12–18°C) are moderate and would support reasonable drying rates if sustained dry weather arrives, but the current unsettled pattern with high humidity (79% average over 7 days) is severely limiting evaporation.
Contributing Factors
6
Over 40mm has fallen since May 30 with 34mm concentrated June 1–4, deeply saturating the porous Fell Sandstone.
Repeated light showers on June 6, 8, and 9 have prevented any meaningful drying window since the heavy rain ended.
Average humidity of 79% over the past week severely limits evaporative drying even with good wind exposure.
Today's 4.7mm and tomorrow's forecast 5.1mm will add fresh moisture to already-saturated rock, resetting any drying progress.
Bowden's hilltop position and prevailing SW winds (20–40 km/h) are the best possible drying setup for Northumberland sandstone.
The June 1–July 30 bird restriction is in effect and may limit access to parts of the crag.
Recommendations
3
- Do not climb today or in the next two days — the rock is deeply saturated and further rain is forecast through June 11.
- The earliest realistic window opens June 13–14 after two full dry days from June 12; check ground conditions at the crag base before committing.
- Verify current bird nesting restrictions via the BMC RAD before visiting, as the June 1–July 30 closure may affect your planned routes.

Bowden Doors has received over 30mm of rain in the last 7 days, including significant falls on June 1–4 (34.2mm total) and further rain today. The porous Fell Sandstone will be thoroughly saturated internally despite any surface drying, and continued rain in the forecast means conditions will not improve for several days.
Based on weather conditions only — does not cover bird nesting restrictions or other access issues.
- The upper tier at Bowden Doors is known for persistent seepage after wet spells — the 34mm+ received June 1–4 will likely still be feeding seepage lines even where the main face appears dry.
- The bird nesting restriction (June 1–July 30) is now active and may limit access to certain sections of the crag; check the BMC RAD for current closures before visiting.
- Bowden's exposed hilltop position and SW/W aspect are assets for drying, but the sheer volume of recent rain (40mm in the last 28 days, 30mm in the last 7) overwhelms these advantages.
- The long dry spell from May 11–21 would have left the rock in excellent baseline condition, but the sustained wet period since June 1 has fully re-saturated the sandstone.
Warnings
2
- Fell Sandstone loses up to 50% of its compressive strength when wet — climbing now risks irreversible hold breakage and permanent route damage.
- The bird nesting restriction (June 1–July 30) is active; some routes may be closed regardless of rock conditions.
Reasoning
With 34.2mm falling June 1–4, only a brief dry window June 5–7, and further rain today (2.8mm), the Fell Sandstone is almost certainly saturated well beyond the critical 1% threshold at which significant weakening begins.
The one meaningful dry gap (June 5 and 7, with 0.5mm on June 6) provided only partial surface drying aided by strong SW winds (~29–40 km/h), but this is wholly insufficient to dry the interior after 34mm of rain; today's 2.8mm re-wets the surface.
At estimated saturation levels, compressive strength reduction of 10–50% is expected; climbing risks hold breakage and permanent damage to the iron-oxide holds that define Bowden's routes.
Early June temperatures (12–16°C) and moderate humidity (70–88%) provide reasonable but not exceptional drying potential; the active bird nesting restriction also limits access.
Contributing Factors
6
Over 34mm fell June 1–4 with additional light rain on May 30–31 and today, thoroughly saturating the porous sandstone.
Only 1–2 truly dry days (June 5 and 7) occurred between the heavy rain and today's further precipitation, far short of the 2–3 dry days required.
Average humidity over the last 7 days is 80%, significantly slowing evaporation from the rock surface.
Bowden's hilltop exposure and SW-facing aspect with consistent 20–40 km/h winds provide the best possible drying conditions for Northumberland sandstone.
Tomorrow and June 10 bring a further 10.5mm of rain, preventing any meaningful drying until at least June 11.
The June 1–July 30 bird nesting restriction is now in force and may close parts of the crag regardless of conditions.
Recommendations
3
- Do not climb at Bowden Doors today or in the next few days — the rock is saturated from 30mm+ of recent rain and climbing risks permanent hold damage.
- Monitor conditions from June 13 onwards if the forecast dry spell materialises, but confirm at least 2–3 full dry days with low humidity before visiting.
- Check the BMC RAD for current bird nesting restrictions before planning any visit during the June 1–July 30 closure period.

Bowden Doors has received nearly 35mm of rain over the past week, with the last significant rainfall (10.1mm) only three days ago and further light rain on June 6th. With only one confirmed dry day since, the porous Fell Sandstone will still be holding substantial internal moisture despite any surface drying. Additionally, the bird nesting restriction (June 1–July 30) is currently active and may limit access to parts of the crag.
Based on weather conditions only — does not cover bird nesting restrictions or other access issues.
- The bird nesting restriction is active from June 1 to July 30, which may restrict access to sections of the crag — check BMC RAD for current closures before visiting.
- Upper tier seepage at Bowden Doors tends to persist longer than the lower boulders after prolonged wet spells, and the past week's 35mm of cumulative rain will feed seepage lines for several days.
- Despite the exposed hilltop position aiding wind-driven evaporation, recent humidity averaging 83% over the last seven days has significantly slowed drying rates.
- The long dry spell from May 10–28 means deeper rock was well-dried before this wet period, which slightly limits total saturation depth compared to a winter scenario — but the surface and near-surface rock is still compromised.
Warnings
3
- Bird nesting restriction is active (June 1–July 30) — check BMC RAD for specific route and area closures before visiting.
- The rock surface may appear dry in the wind while remaining dangerously saturated internally — do not be misled by surface appearance.
- Climbing on wet Fell Sandstone causes permanent, irreversible damage to holds and routes.
Reasoning
With 34.7mm of rain in the past seven days — including 10.1mm on June 4th and 6.1mm on June 3rd — and only one full dry day since, the porous Fell Sandstone (up to 20.7% porosity) will be significantly saturated internally despite any surface drying.
Strong SW winds (28–30 km/h) and the favourable WSW aspect are helping surface evaporation, but persistently high humidity (83% average over the last week) is severely limiting net evaporation rates, meaning the rock needs considerably more dry time.
At current estimated saturation levels, compressive strength could be reduced by 10–30% or more, putting iron oxide holds and grain-cemented features at real risk of breakage under climbing loads.
Early June temperatures (~13–16°C) are moderate and freeze-thaw is not a concern, but the active bird nesting restriction (June 1–July 30) adds an access constraint beyond weather conditions.
Contributing Factors
7
34.7mm fell in the past seven days, with the heaviest falls (10.1mm and 6.1mm) occurring only three days ago, far exceeding the threshold that requires 2–3 dry days minimum.
Only one confirmed dry day has elapsed since the last rain on June 6th (0.5mm), and only three days since the heaviest fall (10.1mm on June 4th) — well short of the 48–72+ hours needed.
Humidity has averaged 83% over the past week, drastically reducing evaporation rates and prolonging internal moisture retention.
Strong SW winds (29.9 km/h today) and the exposed hilltop position are the main drying assets, accelerating surface evaporation compared to sheltered crags.
The WSW-facing aspect receives good afternoon solar radiation in June, aiding surface drying when humidity allows.
The June 1–July 30 bird nesting restriction is currently in effect and may close sections of the crag regardless of rock conditions.
The next five days forecast a further 17.4mm of rain across four of five days, preventing any meaningful cumulative drying.
Recommendations
3
- Do not climb at Bowden Doors today — the rock needs at minimum two to three consecutive dry days after last week's heavy rain, and only one dry day has passed.
- Check the BMC RAD for the current bird nesting restriction details before planning any visit during June or July.
- Monitor conditions closely for a sustained dry window; the forecast suggests the earliest realistic opportunity may not arrive until June 13th or later, assuming rain stops as predicted.

Bowden Doors has received over 36mm of rain in the past week across multiple days (June 1–4), with only one full dry day (June 5) before today's further light rain. The porous Fell Sandstone will be saturated internally despite any surface drying, and the forecast shows continued wet weather for the next five days.
Based on weather conditions only — does not cover bird nesting restrictions or other access issues.
- The upper tier at Bowden Doors is known for persistent seepage after prolonged rain, and the cumulative 36mm over June 1–4 will have thoroughly charged these seepage lines.
- Although the exposed hilltop position and SW aspect normally aid drying, the high humidity (82% average over the past week) and only a single dry day since the last heavy rain severely limit evaporation.
- Bird nesting restrictions are in effect June 1–July 30, which may limit access to certain sections of the crag regardless of conditions.
- The long dry spell from May 9–28 means the rock was in excellent condition before this wet period, but the subsequent 36mm across four days has fully re-saturated the sandstone and reset the drying clock.
Warnings
2
- Climbing on saturated Fell Sandstone risks permanent hold breakage and irreversible damage to routes — the rock may appear dry on the surface while remaining dangerously weak internally.
- The forecast shows no adequate drying window for at least the next five days; do not attempt to climb based on brief dry spells between rain events.
Reasoning
With 36.4mm of rain over the past seven days — including 10.6mm on June 2 and 10.1mm on June 4 — followed by only one dry day and then today's 0.9mm, the rock is almost certainly saturated well beyond the critical 1% threshold at which significant weakening begins.
Only June 5 was fully dry since the heavy rain ended, and despite decent SW wind (28 km/h) and the crag's exposed position, a single day at 15°C with 67% humidity is wholly insufficient to dry porous Fell Sandstone after 36mm of cumulative rainfall.
At current internal moisture levels, Fell Sandstone could be experiencing 30–50% compressive strength loss, creating serious risk of hold breakage — particularly on the iron-oxide-cemented small holds that define many Bowden Doors routes.
Early June temperatures (averaging 12.7°C) and persistently high humidity (82%) are below-average for summer drying, and the forecast shows continued unsettled weather that will prevent adequate drying for at least the next five days.
Contributing Factors

36.4mm fell over the past week across four separate rain days (June 1–4), thoroughly saturating the porous sandstone.
Only one full dry day (June 5) has elapsed since the last heavy rain, far short of the 2–3 dry days minimum required after heavy rain at this crag.
Average humidity of 82% over the past week and 87% today severely limits evaporative drying from the rock surface.
A further 0.9mm today resets any surface drying progress and adds moisture to already saturated rock.
The hilltop exposure and moderate-to-strong winds (26–29 km/h recently) do aid drying, but cannot overcome the moisture deficit in just one day.
The next five days forecast a further 33mm of rain, meaning no adequate drying window is available until at least June 12.
The June 1–July 30 bird nesting restriction is currently in effect, potentially limiting access to parts of the crag.
Recommendations
3
- Do not climb at Bowden Doors today or in the coming days — the rock is saturated and structurally weakened, with further rain forecast through June 11.
- Monitor conditions from June 12 onward; you will need at least 2–3 consecutive dry days with moderate temperatures and low humidity after the rain stops before the rock is safe.
- Check the current bird nesting restriction status (June 1–July 30) via the BMC RAD before planning any visit, as some routes may be off-limits regardless of conditions.
