Condition Analysis
AI-powered assessment using site data and 14-day weather history
Angel Bay is subject to a seal breeding season access restriction from August to December, making it off-limits from today onwards. Even setting aside the access restriction, today's elevated humidity (81%) would make the north-facing limestone greasy and friction-poor.
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 August to December — the crag is currently within the closed period and must not be visited.
- The north-facing aspect receives virtually no direct sun, meaning any moisture or humidity lingers on the rock surface far longer than at south-facing venues.
- The venue is sheltered from prevailing westerly winds, which reduces the drying benefit of the moderate-to-strong winds recorded recently.
- Limestone caves and roof features at the crag can harbour seepage and condensation even during prolonged dry spells, especially in humid coastal air.
Warnings
2
- Angel Bay is CLOSED for climbing from August to December to protect breeding grey seals — visiting risks disturbing a protected species and jeopardising future access.
- Do not attempt to access the crag even if conditions appear dry; the seasonal restriction is absolute.
Reasoning
Today saw 0.2mm of precipitation with 81% humidity — the rock surface will carry a greasy moisture film, particularly on the sheltered, north-facing limestone.
Despite a largely dry preceding week (only 0.2mm in 7 days), the north aspect and sheltered position limit drying, and the high humidity today negates recent drying gains.
Limestone does not suffer structural weakening when damp, but surface friction is severely compromised in humid coastal conditions.
August marks the start of the grey seal breeding season access restriction, which runs through December — this is the overriding factor preventing any climbing at this venue.
Contributing Factors
5
Angel Bay is restricted from August to December to protect breeding grey seals, and today (14 August) falls squarely within the closure period.
Humidity at 81% will make the north-facing limestone extremely greasy and unsafe to climb on.
Only 0.2mm of rain in the last 7 days means the rock itself is not waterlogged or seeping significantly.
The north aspect and shelter from prevailing winds mean any surface moisture or humidity-driven grease dissipates very slowly.
Over 11mm of rain is forecast in the next 5 days, with heavy rain and strong winds on August 18–19, further precluding any conditions improvement.
Recommendations
3
- Do not visit Angel Bay — the seal breeding season closure is in effect from August through December.
- Consider alternative limestone venues in North Wales such as the Great Orme or Parisella's Cave that are not subject to seasonal restrictions.
- Check the BMC Regional Access Database for the latest access status before visiting any coastal crag in the Llandudno area.

Weather conditions today are good with 7 consecutive dry days and low humidity, and the rock should be dry — however, Angel Bay has a seasonal access restriction for grey seal breeding from August to December, and today's date (13 August) falls within that restricted period. Climbers should not visit without first confirming current access status, as the restriction is likely in effect.
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 August to December — today (13 August) falls within the restricted period, so access may be prohibited regardless of climbing conditions.
- The north-facing aspect and sheltered position below the Little Orme mean the crag receives very little direct sun, so even modest humidity can leave limestone surfaces feeling greasy.
- Cave and roof features at Angel Bay can retain seepage moisture long after rain, and the proximity to the sea adds salt humidity that further reduces friction on limestone.
- The beach-level approach may be tide-dependent — check tide times and swell conditions before committing to the descent.
Warnings
2
- Angel Bay has a seasonal access restriction for grey seal breeding from August to December — do NOT visit without confirming current access status via the BMC RAD or local contacts.
- Rain is forecast tomorrow (6.4mm) followed by heavy rain on 17 August (22.2mm) — today may be the last viable climbing window for several days, but only if access is permitted.
Reasoning
With 7 consecutive dry days and only trace precipitation in the last fortnight, the rock surface should be largely dry, though the north-facing aspect and coastal humidity mean pockets and cave features may still harbour residual dampness.
Moderate westerly winds and low-altitude coastal exposure have provided reasonable drying, but the sheltered north-facing position limits solar drying significantly compared to south-facing venues.
Limestone does not suffer structural weakening from moisture, so hold integrity is not a concern after this dry spell.
The critical seasonal factor is the grey seal breeding restriction from August to December — this is the primary barrier to climbing today, overriding the otherwise favourable weather window.
Contributing Factors
6
Angel Bay's August–December access restriction for grey seal breeding is now in effect, and climbers must verify access is permitted before visiting.
No measurable rain since 6 August, giving ample drying time for exposed limestone surfaces.
Humidity averaging 64% over the past week is acceptable for limestone friction, though the north-facing sheltered aspect may feel damper than the numbers suggest.
6.4mm of rain is forecast for 14 August, which will reset drying and make conditions poor for at least a day.
A significant 22.2mm rainfall event forecast for 17 August with 90% humidity and 40+ km/h winds will thoroughly soak the crag.
The north-facing orientation receives minimal direct sunlight even in summer, slowing evaporation from pockets, tufas, and cave features.
Recommendations
3
- Check the BMC RAD and local access agreements before visiting — the August–December grey seal breeding restriction is likely active and must be respected.
- If access is confirmed open, today offers the best weather window before rain arrives tomorrow; prioritise the drier midday hours when humidity is lowest (53–64%).
- Avoid the cave and roof features if any seepage or greasy patches are found — retreat to exposed wall routes where wind has aided drying.

Weather conditions today are excellent for climbing with 6 consecutive dry days, low humidity, and warm temperatures — however, Angel Bay has a seasonal access restriction for grey seal breeding from August to December, and today falls within that restricted period. Climbers must verify current access status before visiting; if access is closed, do not climb regardless of conditions.
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 August to December — today (12 August) falls within this window, and climbers must check the current access status with NRW/BMC RAD before visiting.
- The north-facing aspect means the crag receives minimal direct sun, so even on warm days like today, shaded pockets and cave features can retain moisture longer than south-facing venues.
- The venue is sheltered from prevailing westerly winds by the Little Orme headland, which reduces wind-assisted drying but also means it stays dry during west-driven rain events.
- Cave and roof features at Angel Bay can accumulate condensation and humidity-driven greasiness even after prolonged dry spells, particularly on humid days.
Warnings
2
- Grey seal breeding season restriction is active from August — do NOT visit without confirming current access status with NRW/BMC RAD.
- Conditions deteriorate significantly from Thursday (14 Aug) with rain and high humidity forecast through the weekend.
Reasoning
Six consecutive dry days with only trace precipitation in the prior week (1.3mm total) mean the rock surface should be thoroughly dry, and today's low humidity of 53% is excellent for limestone friction.
Despite the north-facing aspect limiting direct sun, moderate winds and multiple dry days have provided ample drying time; even sheltered cave features should be dry by now.
Limestone does not suffer structural weakening from moisture, so there is no hold-breakage concern; the main risk is surface greasiness if humidity rises.
August marks the beginning of the grey seal breeding season at Angel Bay, which is the primary concern overriding what would otherwise be good summer climbing conditions.
Contributing Factors
5
Angel Bay's seasonal closure for grey seal breeding runs August to December, and today (12 August) falls squarely within this restricted period.
No measurable rain since 6 August (1.3mm trace), giving ample time for all surfaces including caves and pockets to dry.
Humidity of 53% with afternoon lows around 42% is excellent for limestone friction and minimises greasiness risk.
The north aspect limits direct sun, but after 6 dry days this is a minor factor for residual moisture.
Rain forecast on 14 August (2.4mm) and 16–17 August (4.2mm combined) with rising humidity will deteriorate conditions later this week.
Recommendations
3
- Check the current access status with NRW and the BMC RAD before visiting — the August–December seal breeding restriction may prohibit climbing entirely.
- If access is confirmed open, today offers the best conditions window this week; friction will deteriorate from Thursday onward with incoming rain and humidity.
- Avoid cave features if humidity rises above 70% on subsequent days, as condensation can make limestone holds dangerously slippery.

Angel Bay has a seasonal access restriction for grey seal breeding from August to December — today (10 August) falls within this closed period. Regardless of weather conditions, climbers should not visit this crag until the restriction is lifted.
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 this closure period.
- The crag is north-facing and sheltered from prevailing westerlies, meaning it dries slowly despite partial wind exposure — humidity in the 70s can leave limestone greasy.
- Cave and roof features at Angel Bay can retain seepage and humidity-driven moisture even during otherwise dry spells.
- Access involves descent to a hidden beach on the Little Orme headland; tidal conditions and swell should always be checked even outside the seal restriction period.
Warnings
2
- Angel Bay is CLOSED for grey seal breeding from August to December — do not visit during this period.
- Disturbing breeding seals is a criminal offence under the Conservation of Habitats and Species Regulations; penalties include fines and prosecution.
Reasoning
The rock has had four consecutive dry days with only trace precipitation recently, and humidity today is moderate (57–67% during climbing hours), so surface moisture would likely be acceptable if access were permitted.
North-facing aspect limits direct sun but partial wind exposure and moderate breeze (~12–16 km/h) have aided drying since the last light rain on 6 August (1.3 mm).
Limestone does not suffer structural weakening when damp, so hold breakage risk is minimal.
The critical seasonal factor is the grey seal breeding restriction from August to December — this overrides any weather-based assessment and makes the crag off-limits.
Contributing Factors
5
Angel Bay is restricted from August to December for grey seal breeding, and today (10 August) is within the closure period.
Only 1.3 mm fell on 6 August with four fully dry days since, which would normally be adequate drying for limestone.
Humidity today ranges from 57–67% during peak hours, which is acceptable for limestone friction but not ideal.
The north aspect receives minimal direct sun, slowing evaporation of any residual moisture in pockets and cave features.
Today's northerly wind does reach the crag, but the site is generally sheltered from the prevailing westerly winds that would aid drying most effectively.
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 before planning any visit.
- Consider nearby alternative limestone venues on the Great Orme or in the Llandudno area that do not have seasonal restrictions.
- If planning a return visit after the restriction lifts (likely January), check both access status and tidal/swell conditions before descending to the beach.

While the rock has had 3 dry days after only light recent rainfall, Angel Bay is subject to a significant grey seal breeding restriction from August to December — access should not be attempted without checking current status. Even setting the restriction aside, rising humidity in the forecast (up to 90%) will make north-facing limestone greasy and conditions unreliable.
Based on weather conditions only — does not cover bird nesting restrictions or other access issues.
- Angel Bay is a major grey seal breeding site with access restricted August to December; climbers must check the current access status with the BMC RAD or local ranger before visiting, as disturbance to breeding seals can result in pup mortality.
- The north-facing aspect receives minimal direct sun, so moisture from light showers and coastal humidity lingers on the rock surface far longer than at south-facing venues.
- The crag is sheltered from prevailing westerly winds, which limits airflow-driven drying despite the site's partial wind exposure rating.
- Cave and roof features — the main draw of this venue — can trap humid air and remain greasy even when open walls feel dry, especially at humidity above 75%.
Warnings
2
- Grey seal breeding season is NOW ACTIVE (August–December) — do not visit without confirming current access status; disturbance can cause seal pup abandonment and death.
- Humidity is forecast to reach 90% by August 13th, making north-facing limestone dangerously slippery; do not commit to steep or poorly protected routes in these conditions.
Reasoning
The last significant rain was 2.7mm on August 4th followed by lighter showers on Aug 5–6, giving 3 full dry days; surface moisture from direct rainfall should have cleared, but the rock may retain a moisture film from coastal humidity.
North-facing aspect and shelter from prevailing westerlies severely limit drying; the moderate easterly and southwesterly winds of the past few days provide some airflow, but are not optimal for this sheltered, shaded venue.
Limestone does not suffer structural weakening from moisture, so hold integrity is not a concern; the risk is purely friction-related.
It is now August, meaning the grey seal breeding restriction is active and access may be prohibited; even if technically open, climbers should exercise extreme sensitivity around wildlife.
Contributing Factors
6
Angel Bay's August–December seal breeding restriction is now in effect, and access may be closed or heavily restricted.
Three consecutive dry days since the last light rain (1.3mm on Aug 6) should have cleared direct surface moisture from most faces.
Humidity is forecast to climb from 66% tomorrow to 90% by August 13th, which will make north-facing limestone extremely greasy.
The north-facing, wind-sheltered orientation minimises solar drying and airflow, causing moisture and humidity films to persist longer than at sunnier venues.
Only 5.2mm fell in the past 7 days and 6.8mm over 28 days, so there is no deep saturation or prolonged seepage concern.
Proximity to the sea at just 10m altitude creates persistent salt-humidity that coats limestone surfaces with a thin moisture film, reducing friction.
Recommendations
3
- Check the BMC RAD and contact local rangers to confirm whether Angel Bay is currently accessible under the August–December seal breeding restriction before making any plans.
- If access is confirmed open, target the earliest dry morning (Aug 10 looks best at 66% humidity) before humidity climbs significantly mid-week.
- Carry a towel and soft brush and be prepared to walk away if holds feel greasy — cave and roof features will be the first to lose friction as humidity rises.

Angel Bay is subject to a seasonal access restriction for grey seal breeding from August to December — climbing is not permitted at this time. Regardless of rock conditions, climbers must respect this closure to protect the seal colony.
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 (8 August) falls within the closure period.
- The north-facing aspect and sheltered beach setting retain coastal humidity, and cave/roof features can hold condensation even in otherwise dry spells.
- Recent light but repeated precipitation (2.7mm on Aug 4, plus smaller amounts on Aug 3, 5, and 6) combined with humidity around 65–77% means limestone surfaces may still carry a greasy film.
- The venue is sheltered from prevailing westerly winds by the Little Orme headland, which reduces effective drying on the rock despite moderate regional wind speeds.
Warnings
2
- Angel Bay is CLOSED for climbing from August to December due to grey seal breeding — accessing the crag during this period risks disturbing a protected species and jeopardises future access for all climbers.
- Even outside the closure, the sheltered cave and roof features can be dangerously greasy in humid conditions; always touch-test holds before committing to routes.
Reasoning
Light rain on Aug 4 (2.7mm), Aug 5 (0.7mm), and Aug 6 (1.3mm) followed by only two dry days means residual moisture likely persists in pockets and cave features, with humidity averaging around 67%.
The north-facing aspect receives minimal direct sun, and shelter from the headland reduces wind effectiveness, so despite two dry days and moderate breezes the limestone — especially cave and roof sections — will not have fully shed surface moisture.
Limestone is not structurally weakened by moisture, but greasy friction on damp holds poses a significant fall risk, particularly on the roof problems and cave features Angel Bay is known for.
August marks the start of the grey seal breeding season, making Angel Bay off-limits regardless of weather conditions; this is the overriding factor.
Contributing Factors
5
Angel Bay is restricted from August to December to protect breeding grey seals, and today falls within this closure period.
Cumulative rain of ~4.7mm between Aug 3–6, with only two fully dry days since, leaves residual moisture in pockets and cave features.
The north-facing orientation and headland shelter limit both solar drying and wind exposure, slowing evaporation from the limestone.
Humidity has averaged around 68% over the past week, sufficient to create a greasy film on limestone surfaces, particularly in shaded cave features.
Temperatures around 18–22°C support reasonable ambient drying, though this is insufficient to overcome the sheltered, north-facing microclimate quickly.
Recommendations
3
- Do not visit Angel Bay — the grey seal breeding closure is in effect from August to December; check the BMC RAD for the latest access status before planning any visit.
- Consider nearby alternatives on the Great Orme or other North Wales limestone venues that are not subject to seasonal restrictions.
- If visiting after the closure lifts, allow at least 48 hours of dry weather with humidity below 70% for best friction on this north-facing, sheltered limestone.

Angel Bay is currently subject to a seasonal access restriction for grey seal breeding (August to December). Regardless of rock conditions, climbers should not visit this venue until the restriction is lifted. Weather conditions are otherwise reasonable, with only light recent rain and a dry forecast ahead.
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 closed period.
- The north-facing aspect and sheltered beach setting mean humidity lingers and limestone can remain greasy even without direct rain.
- Cave and roof problems may stay dry during light rain but accumulate humidity-driven moisture that reduces friction on holds.
- Coastal proximity means salt spray and ambient marine humidity can create a thin moisture film on the limestone even during dry spells.
Warnings
2
- ACCESS CLOSED: Angel Bay has a seasonal access restriction for grey seal breeding from August to December — do not visit during this period.
- Violating wildlife access restrictions risks harm to protected species and jeopardises future climbing access at this and other sensitive venues.
Reasoning
Only 1.3mm fell yesterday (Aug 6) and today is dry, so surface moisture from recent light showers is likely minimal, but the north-facing aspect and coastal humidity (averaging 68%) will keep the limestone slightly greasy.
Moderate westerly and southwesterly winds provide reasonable surface drying, but the sheltered beach setting and north-facing orientation limit direct sun exposure, slowing evaporation.
Limestone is non-porous and not at risk of structural weakening from moisture; the primary concern is surface friction loss from residual dampness and humidity.
The critical seasonal factor is the grey seal breeding restriction active from August to December, which currently prohibits access to Angel Bay regardless of climbing conditions.
Contributing Factors
5
Angel Bay is closed to climbers from August to December to protect breeding grey seals, and this restriction is currently in effect.
Light rain on Aug 4 (2.7mm), Aug 5 (0.7mm), and Aug 6 (1.3mm) with only one full dry day since may leave residual dampness on sheltered north-facing limestone.
Average humidity around 68% with coastal marine influence can make limestone greasy, particularly on north-facing surfaces that receive no direct sun.
No precipitation is forecast for the next five days, which would allow thorough drying if access were permitted.
Moderate winds of 20–28 km/h from varying directions will help surface drying, though the sheltered beach setting reduces their effectiveness.
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 the exact dates the restriction lifts.
- Consider nearby alternative limestone venues on the Great Orme or in the Llandudno area that are not subject to seasonal closures.
- If planning a return visit outside the restricted period, aim for a spell of at least two dry days with humidity below 70% for best friction on this north-facing limestone.

Although recent rainfall has been minimal and drying conditions are reasonable, Angel Bay is subject to a seal breeding access restriction from August to December — today is 6th August, meaning the crag is very likely closed. Even if access were permitted, the north-facing aspect and coastal humidity would warrant careful assessment of friction on the limestone.
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 (6th August) falls within the restricted period, so climbers must check current access status via the BMC RAD before visiting.
- The north-facing aspect means the crag receives virtually no direct sunlight, so any moisture from light showers or sea spray lingers longer than at south-facing limestone venues nearby.
- The venue is sheltered from prevailing westerly winds by the Little Orme headland, reducing the wind-drying benefit despite moderate regional wind speeds.
- Cave and roof features at Angel Bay can trap humid coastal air, making holds greasy even on days without rainfall — friction is noticeably worse above ~75% humidity.
Warnings
2
- Grey seal breeding access restriction is in effect from August to December — climbing may be prohibited regardless of conditions; verify before travelling.
- North-facing coastal limestone can feel deceptively greasy even when visually dry; do not trust appearances alone.
Reasoning
Only trace precipitation has fallen recently (0.4mm today, 2.7mm on Aug 4th), so the rock surface should be largely dry, but the north-facing coastal limestone will retain a thin moisture film in humid conditions.
Moderate westerly winds have aided surface drying, but the sheltered, north-facing aspect limits evaporation; the light rain from today and recent days should clear within 12–24 hours.
Limestone does not suffer structural weakening when damp, so hold breakage risk is negligible and not a concern here.
August marks the start of the grey seal breeding restriction period at Angel Bay, which is the overriding concern regardless of weather conditions.
Contributing Factors
5
Angel Bay's access restriction runs August–December to protect breeding grey seals, and today (6 August) falls within this window.
Only 4.5mm over the past 7 days in trace amounts means the rock has had good opportunity to dry between showers.
The north-facing orientation and shelter from westerly winds limit both solar drying and wind exposure, keeping surfaces damper for longer.
Humidity averaging 68% over the past week, with spikes into the mid-70s, is enough to make limestone friction noticeably poor, especially in shaded cave features.
Sustained winds of 20–30 km/h from varying directions have helped disperse surface moisture despite the sheltered aspect.
Recommendations
3
- Check the BMC RAD and local notices immediately — the August–December seal breeding restriction is almost certainly in effect and access may be prohibited.
- If access is confirmed open, visit during the afternoon when humidity drops to its daily low (57–64% forecast today) for the best friction.
- Carry a towel and chalk and test friction on lower holds before committing to anything committing; retreat if the limestone feels greasy.

Angel Bay has had very little rain recently, but today's morning showers and persistent high humidity on this north-facing, sheltered limestone venue will leave surfaces greasy. Critically, August marks the start of the grey seal breeding season — access is restricted from August to December, and climbers must check current access status before visiting.
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 August through December; today falls within the restricted period and climbers must verify current access status via the BMC RAD before any visit.
- The crag is sheltered from prevailing westerly winds by the Little Orme headland, meaning the forecast strong westerlies will provide less drying benefit here than at more exposed venues.
- North-facing aspect at sea level means virtually no direct sun reaches the rock, so humidity-driven greasiness on limestone persists longer than weather data alone might suggest.
- Cave and roof features characteristic of this venue trap humid air and can remain greasy even when open walls feel acceptable.
Warnings
2
- Angel Bay is a grey seal breeding site with access restricted August to December — visiting during this period may cause serious disturbance to protected wildlife and breach access agreements.
- Limestone at this sheltered, north-facing venue can feel deceptively greasy even when visually dry; test friction carefully on easy ground before attempting harder routes.
Reasoning
Light rain this morning (0.7mm between 06:00–08:00) on top of 0.9mm forecast for today, combined with humidity consistently above 70%, means the limestone surfaces are currently damp and greasy.
The north-facing, wind-sheltered aspect limits both solar drying and wind exposure; although afternoon humidity may drop to 60–68%, the morning wetness on limestone will take several hours to clear fully in these conditions.
Limestone does not suffer structural weakening from moisture, so hold breakage risk is minimal regardless of dampness.
Mid-summer provides the best general drying conditions, but the onset of the August–December seal breeding restriction is the dominant seasonal concern at this specific venue.

August marks the start of the grey seal breeding season at Angel Bay, with access restricted August–December — this alone may prevent climbing regardless of weather.
Light rain this morning and sustained humidity above 75% will leave the north-facing limestone greasy through the middle of the day.
The crag is sheltered from the prevailing westerly winds, reducing the drying effect of tomorrow's strong 38 km/h westerlies and today's moderate breeze.
North aspect at low altitude receives virtually no direct sunlight, meaning humidity is the primary driver of surface condition and it remains unfavourable.
Only 3mm of rain in the past 28 days means there is no deep seepage or prolonged drainage concern on the limestone.
Humidity is forecast to dip to 60–65% between 17:00–20:00 with some wind, which could create a brief window of improved friction if access were permitted.
Recommendations
3
- Check the BMC RAD and local signage for Angel Bay's current grey seal breeding restriction before planning any visit — August falls within the restricted period.
- If access is confirmed open, the best friction window today would be late afternoon (17:00–19:00) when humidity briefly dips below 65%, but test the rock thoroughly before committing.
- Consider nearby alternative crags with south or west-facing aspects and better wind exposure for more reliable drying conditions.

Angel Bay received light rain earlier today with heavier showers forecast from late afternoon onward, and the site enters its seal breeding access restriction period in August. Even during the dry midday window, the north-facing aspect and coastal humidity mean limestone friction will be marginal at best, and the access restriction is the overriding concern.
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 through December — today (3 August) falls within this restriction period, and climbers must verify current access status via the BMC RAD before any visit.
- The crag is sheltered from prevailing westerly winds by the Little Orme headland, which reduces drying effectiveness during the dominant W/NW wind patterns forecast for the coming days.
- Cave and roof features can retain seepage and humidity-driven moisture for extended periods, even when open walls appear dry — pockets and tufas are particularly prone to greasy conditions.
- North-facing aspect at near sea level means essentially zero direct sun exposure, making the site heavily reliant on wind and low humidity for drying.
Warnings
3
- CRITICAL: Angel Bay is a grey seal breeding site with access restricted August to December — verify access is permitted before any visit.
- Rain is forecast from 17:00 today onward; do not start routes late in the day as retreat on wet limestone is hazardous.
- The coming week features repeated rain and high humidity with minimal drying — conditions will not improve at this north-facing venue.
Reasoning
Light rain overnight (0.1mm) plus 2.4mm total today, with showers forecast from 17:00 onward, means the rock will be damp through the evening and into tomorrow.
The north-facing aspect receives no direct sun, and while the midday window (08:00–16:00) shows low humidity (32–55%) and light SE winds, the sheltered position limits effective drying before evening rain arrives.
Limestone does not suffer structural weakening from moisture, but greasy conditions on this north-facing coastal venue pose a significant slip hazard.
August marks the start of the grey seal breeding restriction period at Angel Bay, which is the primary concern regardless of weather conditions; climbers must confirm access is permitted before visiting.
Contributing Factors
6
August to December access restrictions for grey seal breeding are now in effect, and this overrides any weather-based assessment.
2.4mm total precipitation today with further showers from 17:00 onward will leave the rock wet through the evening.
Between 08:00 and 16:00 humidity drops to 32–55% with no rain, which would normally offer a climbing window on limestone.
The north aspect means no solar drying at all, leaving the crag entirely dependent on wind and ambient humidity for moisture removal.
The next five days show repeated rain events totalling ~10.8mm with high humidity (70–78%), preventing sustained drying.
The headland shelters Angel Bay from the prevailing W/NW winds forecast for the coming days, reducing the primary drying mechanism.
Recommendations
3
- Check the BMC RAD and local notices immediately — the August seal breeding restriction at Angel Bay likely prohibits access from now through December.
- If access is confirmed as open, the only viable window today would be mid-morning to mid-afternoon (roughly 10:00–16:00) when humidity is lowest, but assess holds carefully for residual grease.
- Consider alternative south-facing limestone venues on the Great Orme or Lleyn Peninsula for better drying conditions this week.
