Condition Analysis
AI-powered assessment using site data and 14-day weather history
Angel Bay is currently wet from today's rain with extremely high humidity (88–95%), and a major storm system is forecast to deliver over 70mm of rain across the next three days. Additionally, the seal breeding season restriction (August–December) is now active, making access ethically and likely legally inappropriate.
Based on weather conditions only — does not cover bird nesting restrictions or other access issues.
- Angel Bay is a significant grey seal breeding site with access restricted from August to December — the current date falls within this closure period, so climbing should not take place regardless of weather.
- The north-facing aspect means the crag receives virtually no direct sunlight, so drying relies entirely on wind and ambient conditions, both of which are poor right now.
- Cave and roof features at Angel Bay can retain seepage and humidity-driven moisture for extended periods, making them greasy even when open walls appear dry.
- The sheltered position below the Little Orme headland reduces wind penetration despite partial exposure, further slowing drying after the prolonged wet spell of the last week.
Warnings
3
- CRITICAL: Angel Bay is a grey seal breeding site with access restricted August to December — do not visit during this period.
- Limestone will be extremely greasy and dangerous in the current and forecast conditions; friction will be severely compromised.
- A major rain event (62+ mm over Aug 27–29) will saturate the crag and surrounding headland, causing prolonged seepage.
Reasoning
The rock is wet today from 6mm of rain with humidity at 88–95%, compounded by 19.5mm over the past seven days including significant falls on Aug 19–22.
North-facing aspect receives no direct sun and the sheltered bay limits wind-assisted drying; with persistent cloud cover and humidity above 85%, no meaningful drying is occurring.
Limestone does not suffer structural weakening when wet, but the greasy surface under these saturated humidity conditions creates a serious slip hazard.
Late August marks the start of the grey seal breeding restriction (August–December); this access closure takes precedence over any weather-based assessment.
Contributing Factors
7
Angel Bay's August–December seal breeding closure is now active, prohibiting access to the crag.
6mm of rain today with showers throughout the morning and afternoon leaves the rock thoroughly wet.
Humidity between 88–95% today ensures limestone surfaces remain greasy even between rain showers.
Over 70mm of rain is forecast across Aug 27–30, with 36.5mm on Aug 28 alone, ensuring the crag will be saturated for days.
The north aspect receives no direct sunlight, eliminating the primary drying mechanism for rock surfaces.
19.5mm over the past 7 days has left the rock and surrounding ground already well-saturated before today's rain.
Winds of 40+ km/h forecast from Aug 29–31 will eventually aid surface drying once rain ceases.
Recommendations
3
- Do not visit Angel Bay — the grey seal breeding restriction is active from August through December; check BMC RAD for the latest access status.
- Even if access were permitted, conditions are thoroughly wet and greasy; wait for a sustained dry spell of at least 2–3 days with lower humidity.
- Consider alternative non-restricted limestone venues with south-facing aspects for better drying potential during this wet period.

While the rock has had two dry days and today's afternoon conditions look promising with low humidity and a brisk easterly breeze, Angel Bay is subject to a seal breeding season access restriction from August to December — climbing here today is almost certainly not permitted. Even setting access aside, recent heavy rain (18mm in the last week) on this north-facing, sheltered limestone needs careful assessment.
Based on weather conditions only — does not cover bird nesting restrictions or other access issues.
- Angel Bay has a significant grey seal breeding restriction from August to December; climbers must check the current access status via the BMC RAD before any visit, as the crag is very likely closed right now.
- The north-facing aspect receives virtually no direct sunlight, meaning the limestone relies entirely on wind and ambient warmth for drying — pockets and cave features will retain moisture far longer than exposed faces.
- The crag is sheltered from prevailing westerly winds by the Little Orme headland, but today's easterly breeze may actually reach the face better than usual, aiding surface drying.
- Cave and roof problems at Angel Bay can remain dry through rain events, but humidity-driven greasiness is the primary friction concern on limestone, especially in enclosed cave environments.
Warnings
2
- Angel Bay is a grey seal breeding site with access restricted August to December — do not visit without confirming current access status via the BMC RAD.
- Heavy rain (up to 32mm) is forecast for Aug 27–28 with high winds; do not plan any sea-cliff activity during this period.
Reasoning
Recent rainfall of 6.9mm on Aug 20, 2.7mm on Aug 21, and 3.9mm on Aug 22 totalling over 13mm in three days means the north-facing limestone will still hold residual moisture in seepage lines and pockets despite two dry days.
Two consecutive dry days with moderate wind and today's easterly breeze (up to 27 km/h) and low afternoon humidity (~47%) are helpful, but the north aspect receives no direct sun, limiting evaporation and meaning exposed walls may still have damp patches.
Limestone does not suffer structural weakening from moisture, so hold breakage is not a concern; however, damp limestone is extremely greasy and poses a significant slip hazard.
August marks the start of the grey seal breeding season at Angel Bay, making access restrictions the overriding concern regardless of rock conditions.
Contributing Factors
6
Angel Bay is a significant grey seal breeding site with access restricted from August to December — this is the primary barrier to climbing here today.
Over 13mm fell across Aug 20–22, and the north-facing sheltered limestone has had only two dry days to recover.
Humidity drops to 46–53% through the afternoon with a brisk easterly wind, which is excellent for limestone friction if the rock surface is dry.
No direct sunlight reaches the crag, so drying depends entirely on wind circulation and ambient temperature, slowing recovery from recent rain.
Today's easterly wind direction may penetrate the normally westerly-sheltered bay better than usual, aiding surface drying.
Heavy rain is forecast from Aug 26 onwards, with over 50mm expected in the next five days, making today potentially the last dry window for some time.
Recommendations
3
- Check the BMC RAD and local notices immediately — Angel Bay is almost certainly closed for the grey seal breeding season (August–December) and climbing may be prohibited.
- If access is confirmed as open, visually inspect the rock carefully for greasy patches, especially in pockets, cave interiors, and seepage lines before committing to any routes.
- Consider alternative nearby crags with better aspect and confirmed open access, as deteriorating weather from Aug 26 onwards will close this window entirely.

Angel Bay is currently subject to a seasonal access restriction for grey seal breeding (August to December), meaning climbing should not take place regardless of rock conditions. Additionally, recent rain over the past week and high humidity have left the north-facing limestone likely greasy and damp.
Based on weather conditions only — does not cover bird nesting restrictions or other access issues.
- Angel Bay is a significant grey seal breeding site with access restricted from August to December — the current date falls within this closure period and climbing should not take place.
- The north-facing aspect receives virtually no direct sun, meaning the recent run of wet days (20.3mm in the last 7 days) will leave seepage and dampness lingering in caves and pockets far longer than at south-facing venues.
- The venue is sheltered from prevailing westerly winds by the Little Orme headland, which reduces airflow across the rock and further slows drying.
- Cave and roof features at Angel Bay trap humidity and seepage; even after surface drying these areas can remain greasy for days in the 70–80% humidity range seen recently.
Warnings
3
- ACCESS CLOSED: Angel Bay has a seasonal access restriction for grey seal breeding from August to December — do not visit during this period.
- Approaching the beach risks disturbing breeding seals and their pups, which is both an ethical violation and potentially a legal offence under wildlife protection legislation.
- Even setting aside the access restriction, the rock is likely greasy and unsafe after recent rain with minimal drying on this north-facing venue.
Reasoning
With 20.3mm of rain in the last 7 days — including 6.9mm on the 20th and 3.9mm on the 22nd — and only one dry day since, the north-facing limestone will still hold significant surface moisture and seepage.
The north aspect and sheltered position mean minimal sun and reduced wind exposure, so one dry day with 72% humidity is far from sufficient to dry caves, pockets, and seepage lines after a prolonged wet spell.
Limestone is not structurally weakened by moisture, but the greasy surface friction loss on damp holds creates a serious safety hazard, especially on the cave and roof problems Angel Bay is known for.
August marks the beginning of the grey seal breeding season access restriction (August–December), which is the overriding factor making this venue off-limits regardless of weather conditions.
Contributing Factors
6
Angel Bay is closed from August to December for grey seal breeding, and the current date of 23 August falls squarely within this closure.
20.3mm has fallen in the last 7 days across multiple events, with only one dry day since the last rain on August 22nd.
The north aspect receives almost no direct sunlight, dramatically slowing evaporation and drying of the limestone surface.
Average humidity of 77% over the past week keeps moisture in the rock and creates greasy conditions on limestone holds.
The crag's sheltered position behind the Little Orme reduces the benefit of the moderate winds that might otherwise aid drying.
41.8mm of rain is forecast over the next 6 days, with heavy falls expected from the 26th onwards, meaning conditions will deteriorate further.
Recommendations
3
- Do not visit Angel Bay — the grey seal breeding season access restriction is in force from August to December; check the BMC RAD for the latest access status.
- Consider alternative limestone venues in North Wales that are south-facing and not subject to seasonal restrictions, such as the Orme or Parisella's Cave area (also check access).
- If planning to return to Angel Bay, wait until at least January and ensure a sustained dry spell of 3+ days with low humidity before climbing on the north-facing walls.

Angel Bay has a seasonal access restriction for grey seal breeding from August to December — the crag should not be visited during this period. Additionally, recent heavy rainfall (16.6mm in 7 days) combined with high humidity and the north-facing aspect mean the limestone would be greasy even if access were permitted.
Based on weather conditions only — does not cover bird nesting restrictions or other access issues.
- Angel Bay is a significant grey seal breeding site with access restricted from August to December; today (22 August) falls within this closure period and climbing should not take place.
- The north-facing aspect receives virtually no direct sun, meaning moisture from the recent wet spell (6.9mm on Aug 20, 2.7mm on Aug 21) will linger on the rock surface far longer than at south-facing venues.
- Cave and roof features at Angel Bay can trap humidity and seepage, making holds greasy even after surface rock appears dry.
- The site is sheltered from prevailing westerly winds, which reduces the benefit of the moderate wind exposure and further slows drying on the north-facing walls.
Warnings
2
- ACCESS RESTRICTION: Angel Bay is closed August–December for grey seal breeding — do not visit the crag during this period.
- Even disregarding the access closure, the rock is likely greasy and unsafe for climbing after recent heavy rain and sustained high humidity.
Reasoning
With 16.6mm of rain in the last 7 days — including 6.9mm and 2.7mm on the two days before today — and only a trace of drying today, the rock is almost certainly still damp, particularly in pockets, caves, and seepage lines.
The north-facing aspect and sheltered position mean virtually no direct solar drying; moderate wind from the NW today helps marginally, but one dry day is insufficient to clear moisture from limestone features after this volume of rain.
Limestone does not suffer structural damage from moisture, but greasy conditions on damp holds present a significant slip and injury risk.
Mid-summer temperatures are reasonable for drying, but the elevated humidity (averaging 76% over the last week) keeps the rock surface clammy; critically, the August–December seal breeding restriction makes this entire discussion academic.
Contributing Factors
5
Angel Bay is restricted from August to December for grey seal breeding — access is not permitted during this period regardless of climbing conditions.
16.6mm fell in the last 7 days, with the heaviest falls (6.9mm and 2.7mm) only 1–2 days ago, leaving insufficient drying time.
Humidity has averaged 76% over the past week, which keeps limestone greasy and dramatically reduces friction on holds.
The north-facing orientation and shelter from prevailing winds severely limit natural drying, prolonging moisture retention on the rock.
Only one day of near-dry weather (0.1mm) with 71% humidity provides negligible drying benefit after the recent wet spell.
Recommendations
3
- Do not visit Angel Bay — the grey seal breeding restriction is in effect from August to December; check BMC RAD for the latest access status.
- Consider alternative non-restricted limestone venues on the Great Orme or inland North Wales crags that may have better drying conditions.
- If planning a return visit outside the restriction window, allow at least 2–3 fully dry days with humidity below 70% for reliable friction on this north-facing limestone.

Angel Bay is currently subject to a seasonal access restriction for grey seal breeding (August to December) — climbing should not take place regardless of rock conditions. Additionally, recent persistent rain and high humidity have left the north-facing limestone damp and greasy.
Based on weather conditions only — does not cover bird nesting restrictions or other access issues.
- Angel Bay is a significant grey seal breeding site with access restricted from August to December; today (21 August) falls within the closure period and climbing must not take place.
- The north-facing aspect receives virtually no direct sun, meaning moisture from the recent wet spell (15.8mm in 7 days) will linger on the limestone surfaces far longer than at south-facing venues.
- The crag is sheltered from prevailing westerly winds despite partial exposure, reducing the effectiveness of wind-assisted drying on already slow-drying north-facing rock.
- Limestone caves and roof features at Angel Bay can retain humidity-driven greasiness even when surface rock appears dry, and coastal proximity adds persistent salt moisture.
Warnings
3
- CRITICAL: Angel Bay is closed for grey seal breeding from August to December — do not visit the crag during this period.
- The rock is currently wet and greasy from recent rain; climbing would be dangerous even if access were permitted.
- Significant further rainfall is forecast over the coming days, with no sustained dry window in sight.
Reasoning
With 6.9mm on Aug 20, 2.0mm today, and 15.8mm total over the past week, the rock is wet and the north-facing limestone will be holding significant surface moisture and seepage.
Zero consecutive dry days, a north aspect with minimal solar gain, and only partial wind exposure mean virtually no meaningful drying has occurred since the recent rain sequence.
Limestone does not suffer structural weakening from moisture, but greasy conditions on holds and friction-dependent moves present a serious slip and fall hazard.
Mid-August falls squarely within the grey seal breeding restriction (August–December), making the site off-limits regardless of weather conditions.
Contributing Factors
6
Angel Bay is restricted August to December for grey seal breeding, and today (21 August) is within the closure period.
15.8mm in the last 7 days including 6.9mm on Aug 20 and 2.0mm today leaves the rock wet.
Average humidity of 76% over the past week keeps limestone greasy and inhibits drying, especially on a north-facing crag.
The north aspect receives almost no direct sunlight in summer, dramatically slowing evaporation from rock surfaces.
Shelter from prevailing westerlies reduces wind-assisted drying despite the site's partial exposure rating.
3.8mm forecast for tomorrow and 21.9mm total over the next 6 days means conditions will not improve soon.
Recommendations
3
- Do not visit Angel Bay — the grey seal breeding restriction is in effect from August to December; check the BMC RAD for the latest access status.
- Even if the access restriction were not in place, allow at least 2–3 fully dry days with humidity below 70% before considering this north-facing venue.
- Consider alternative south- or west-facing limestone venues in North Wales that dry faster and are not subject to seasonal restrictions.

Angel Bay is currently subject to a seasonal access restriction for grey seal breeding (August–December) — climbing should not take place regardless of weather conditions. Additionally, 15.3mm of rain today on top of a wet recent spell means the north-facing limestone would be thoroughly soaked and greasy.
Based on weather conditions only — does not cover bird nesting restrictions or other access issues.
- Angel Bay is a significant grey seal breeding site with access restricted from August to December; today (20 August) falls within the closure period and climbing should not take place.
- The north-facing aspect receives virtually no direct sun, meaning moisture from today's heavy rain and the preceding wet days will linger on the rock surface for an extended period.
- The venue is sheltered from prevailing westerly winds, which reduces the air circulation that would otherwise help dry the limestone after rain.
- Cave and roof features at Angel Bay can retain seepage and humidity long after surface rock appears dry, making friction unreliable even after a couple of dry days.
Warnings
2
- ACCESS CLOSED: Angel Bay is a critical grey seal breeding site — access is restricted August to December. Do not visit.
- The rock is currently saturated from 15.3mm of rain today; limestone will be dangerously greasy.
Reasoning
With 15.3mm of rain today, 3.3mm yesterday, and over 22mm in the last week, the rock is thoroughly wet and the north-facing limestone will be extremely greasy.
The north aspect and sheltered position mean negligible solar drying; moderate NW wind today will help somewhat but cannot dry limestone saturated by this volume of rain in under 24–48 hours.
Limestone does not suffer structural weakening from moisture, but greasy wet holds present a serious slip and fall hazard.
Mid-August places this visit squarely within the grey seal breeding restriction (August–December), making the site off-limits regardless of rock conditions.
Contributing Factors
6
Angel Bay is closed August–December for grey seal breeding; visiting during this period is irresponsible and potentially illegal.
15.3mm of precipitation today, mostly falling as a heavy burst around 06:00–07:00, has thoroughly soaked the rock.
Over 22mm of rain in the last 7 days means the rock had no chance to fully dry before today's deluge.
The north aspect and wind-sheltered position greatly reduce natural drying from sun and airflow.
Average humidity of 77% over the past week inhibits evaporation from the limestone surface and cave features.
From 22 August onwards the forecast shows several consecutive dry days with moderate humidity (65–68%), which would begin to improve rock conditions.
Recommendations
3
- Do not visit Angel Bay — the site is closed for grey seal breeding from August to December; check the BMC RAD for the current access status before planning any visit.
- Even ignoring the access restriction, allow at least 2–3 fully dry days after today's heavy rain before considering climbing on this north-facing limestone.
- Consider alternative nearby venues with better drying characteristics (e.g. south-facing limestone on the Great Orme) if you need to climb in the Llandudno area, but check those for seal or bird restrictions too.

- Angel Bay is a significant grey seal breeding site with access restricted from August to December; today falls squarely within this closure and the crag should not be visited.
- The north-facing aspect receives virtually no direct sunlight, meaning moisture from recent rain (2.1mm on Aug 17, 1.1mm on Aug 18, 0.2mm today) lingers on limestone surfaces far longer than at sun-exposed venues.
- The crag is sheltered from prevailing westerly winds despite its coastal position, reducing wind-assisted drying on the climbing surfaces.
- Cave and roof features at Angel Bay can hold seepage and condensation for extended periods, and coastal humidity compounds greasiness on the limestone.
Warnings

- ACCESS RESTRICTED: Angel Bay is closed August to December for grey seal breeding — do not visit the crag during this period.
- Significant rainfall forecast (14.7mm Aug 20, 9.3mm Aug 21) will make conditions even worse over the coming days.
- Disturbing breeding seals can result in pup abandonment and is an offence under wildlife protection legislation.
Reasoning
Recent light rain on Aug 17 (2.1mm), Aug 18 (1.1mm), and today (0.2mm) combined with humidity averaging 74% over the past week means the north-facing limestone surfaces are likely damp and greasy.
With a north aspect receiving minimal direct sun and only partial wind exposure (sheltered from prevailing westerlies), the rock has had negligible drying opportunity since the rain on Aug 17–18.
Limestone does not suffer structural weakening from moisture, but greasy conditions create serious slip hazards on the cave and wall climbing here.
August marks the start of the grey seal breeding season access restriction (August–December), which overrides any weather-based assessment and makes the crag off-limits.
Contributing Factors

Angel Bay is restricted August to December for grey seal breeding, and today (19 August) falls within this mandatory closure period.
Light rain on Aug 17 (2.1mm), Aug 18 (1.1mm), and today (0.2mm) has kept the north-facing limestone damp with no effective drying window.
Average humidity of 74% over the past week makes limestone surfaces greasy even where not directly wetted.
The north aspect receives almost no direct sunlight, severely limiting natural drying of the rock.
14.7mm forecast for Aug 20 followed by 9.3mm on Aug 21 will thoroughly soak the crag and reset any drying progress.
The venue is sheltered from prevailing westerly winds, reducing wind-assisted evaporation from rock surfaces.
Recommendations

- ACCESS RESTRICTION IN EFFECT: Angel Bay is closed August–December for grey seal breeding — do not visit.
- Limestone is currently greasy from recent rain and high humidity; even without the restriction, climbing would be unsafe.
Reasoning
Rain fell today (1.8mm) and yesterday (4.1mm), and with humidity averaging 79% today the rock surface will be damp and greasy.
The north-facing aspect and sheltered position mean wind-assisted drying is limited; even with moderate westerly winds, meaningful drying has not occurred since yesterday's heavier rain.
Limestone does not suffer structural weakening from moisture, but the greasy surface in these humid conditions poses a significant slip hazard.
Mid-August falls squarely within the grey seal breeding restriction (August–December), which is the overriding factor making the site off-limits.

Angel Bay is subject to a seasonal access restriction for grey seal breeding from August to December — today (17 August) falls within this closure period, making the site off-limits regardless of weather conditions. Even setting the restriction aside, today's high humidity (80–95%) and light drizzle would make the north-facing limestone dangerously greasy.
Based on weather conditions only — does not cover bird nesting restrictions or other access issues.
- Angel Bay is a significant grey seal breeding site with access restricted from August to December; the current date falls squarely within the closure period.
- The north-facing aspect means the crag receives virtually no direct sun, so any moisture from light rain or high humidity lingers on the limestone surface far longer than at south-facing venues.
- The venue is sheltered from prevailing westerly winds by the Little Orme headland, reducing the effectiveness of wind-assisted drying despite moderate regional wind speeds.
- Cave and roof features at Angel Bay can remain dry overhead during rain but become extremely greasy when humidity exceeds 75–80%, which is the case today and across the forecast period.
Warnings
3
- ACCESS CLOSED: Angel Bay is restricted August–December for grey seal breeding — do not visit the crag during this period.
- Climbing at this venue during the seal closure risks permanent loss of access for all climbers.
- Even ignoring the restriction, greasy limestone in high humidity poses a serious fall risk.
Reasoning
Light rain overnight (0.3 mm) and today's forecast drizzle (0.8 mm total), combined with sustained humidity of 80–95% through the morning and early afternoon, mean the limestone surfaces are currently damp and greasy.
The north-facing aspect receives no meaningful direct sun, and the sheltered position reduces wind exposure; with humidity remaining above 80% for most of the day, effective drying is negligible.
Limestone does not suffer structural weakening when wet, so hold breakage is not a concern, but the friction loss on greasy limestone is a serious safety hazard.
Mid-August marks the start of the grey seal breeding season at Angel Bay, triggering an access restriction that runs through December — this alone makes the site off-limits.
Contributing Factors

Angel Bay has a seasonal access restriction for grey seal breeding from August to December — today is 16 August, so the crag is currently closed. Even setting aside the access restriction, today's rain (1.1mm) and high humidity (71%) on this north-facing limestone would make conditions greasy and suboptimal.
Based on weather conditions only — does not cover bird nesting restrictions or other access issues.
- Angel Bay is a significant grey seal breeding site with access restricted from August to December; the crag is currently within the restricted period and should not be visited.
- The north-facing aspect receives virtually no direct sun, meaning any moisture from rain or sea spray lingers much longer than at south-facing limestone venues.
- The sheltered cave and roof features can trap humid air even on breezy days, increasing greasiness on holds despite low overall precipitation.
- As a coastal venue on the Little Orme, salt humidity and sea spray add a persistent moisture film that compounds the friction problems of damp limestone.
Warnings
2
- ACCESS CLOSED: Angel Bay is restricted August–December for grey seal breeding — do not visit.
- Climbing during the seal breeding restriction risks permanent closure of the venue and causes serious disturbance to a protected species.
Reasoning
Today saw 1.1mm of rain and humidity is 71%, so exposed limestone surfaces will have a greasy film, particularly on the north-facing rock that receives no direct sun to aid evaporation.
Moderate westerly winds provide some drying, but the sheltered position beneath the Little Orme headland and north-facing aspect mean drying is slow — at least 24–48 hours of dry weather with lower humidity would be needed.
Limestone does not suffer structural weakening from moisture, but greasy conditions pose a serious slip hazard on the steep and roof climbing typical of Angel Bay.
August marks the start of the grey seal breeding season, placing the entire venue under an access restriction that runs through to December — this overrides any weather-based assessment.
Contributing Factors
6
Angel Bay is restricted from August to December to protect breeding grey seals, and today (16 August) falls squarely within that period.
1.1mm today plus 0.7mm on 14 August and intermittent light rain in recent days mean the rock has not had a sustained dry spell.
The north aspect receives almost no direct sunlight in any season, significantly slowing evaporation and keeping the limestone greasy for longer.
Humidity around 71% today and forecast 79% tomorrow is high enough to maintain a greasy film on limestone, reducing friction on holds.
Proximity to the sea adds persistent salt moisture to the rock surface, compounding drying challenges on this sheltered north-facing cliff.
The next five days show daily precipitation of 0.4–2.8mm with no sustained dry window, so conditions will not improve.
Recommendations
3
- Do not visit Angel Bay — the grey seal breeding access restriction is in effect from August to December; check the BMC RAD for current status.
- Consider nearby alternative venues outside the restriction zone, such as the Great Orme's south-facing limestone which dries faster and remains open.
- If planning a return visit, target May–July when access is open and longer days provide the best drying conditions for this north-facing crag.
