Gabbro at Porth Ysgo is non-porous and dries very quickly, so the light scattered showers of recent days (2.2mm on May 2, 2.1mm on May 3, 0.4mm today including 0.3mm forecast at 15:00) are not a major concern structurally. However, high ambient humidity (~80%), overcast skies, and the light shower expected mid-afternoon today mean surfaces should be visually checked before committing — a dry window exists from late morning through early afternoon and again from late afternoon onward.

The rock has had roughly 24 hours of drying since the last light rain (1.3mm on May 6th), with today remaining dry and moderate southerly winds aiding evaporation on this south-facing venue. However, several days of light but persistent precipitation (May 1–6 totalling ~9.3mm) combined with high ambient humidity (~73–81%) mean some seepage areas and sheltered faces may still hold residual moisture.

Almscliff has had four consecutive dry days since the heavy 24.5mm deluge on May 3rd, with moderate temperatures and reasonable wind, but the exposed hilltop S/W aspect has aided drying. The rock surface should be largely dry on south-facing sections, but internal moisture from that significant rainfall event may linger — a visual and tactile check on arrival is essential before committing to climb.

The dolerite at Crag Lough has had roughly a day of drying since the last light rain on May 5th (1.3mm), and today is largely dry through the afternoon with moderate wind aiding surface drying. However, the north-facing aspect, high humidity, and light showers forecast from late afternoon onward mean conditions should be visually assessed on arrival — the rock may still hold residual dampness in sheltered corners.

The Cromlech Boulders have had a damp week with light but frequent precipitation, and today sees only trace amounts; the SW/W-facing rhyolite should be largely surface-dry by late morning but high humidity (77%) and overcast skies limit confidence. A good window exists midday through early evening, but climbers should check holds for residual dampness on arrival.

The last significant rain was 7.2mm on May 3rd, followed by three mostly dry days with moderate temperatures — the south aspect and partial wind exposure have aided drying, but scattered trace precipitation (0.4mm on May 5th, 0.2mm today) and average humidity around 75% mean internal moisture may linger. Conditions are borderline and a careful on-site assessment is essential before committing to climb today, with rain forecast from tomorrow making the coming days unsuitable.

The last significant rain was 1.3mm on May 5th, with a dry day on May 6th and today (May 7th) dry through the afternoon — giving roughly 36–48 hours of drying since the last light rain. However, 7.2mm fell on May 3rd (4 days ago) and the sheltered woodland setting slows drying considerably, so internal moisture may linger; a careful on-site assessment is essential before climbing this afternoon.

The last significant rain was 17mm on May 3rd, followed by three full dry days (May 4–6) with moderate temperatures and reasonable winds, giving a plausible but not fully confident drying window. Today is dry through the afternoon with dropping humidity, but light rain arrived on May 1–2 before the heavy May 3rd event, meaning the rock was already saturated going into that downpour — and the forecast shows more rain arriving tomorrow, so any climbing window is narrow.

Light rain fell yesterday (2.5mm) and today has seen only a trace (0.3mm), but high humidity (avg 80% over the last week) and limited sunshine at 400m mean surface moisture may linger in sheltered spots. The exposed, wind-swept plateau and non-porous rhyolite favour quick drying, so a morning climbing window before the light afternoon drizzle looks plausible — but visual assessment on arrival is essential.

The last significant rain was 11.4mm on May 3rd, followed by only one full dry day (May 4th and 6th) interspersed with 2.3mm on May 5th and trace precipitation today. While the SW aspect and moderate wind have aided drying, the combination of heavy recent rainfall, cool temperatures, and high average humidity means internal moisture is likely still present — conditions require careful on-site assessment before committing to climb.

Shaftoe has had a very wet spring with 16.3mm of heavy rain on May 3rd followed by only three mostly dry days and minor precipitation today; the exposed south-facing aspect and moderate wind have aided drying, but scattered boulders will be in mixed condition. With rain forecast tomorrow and heavy rain on May 9th, today's afternoon window may be the best opportunity — but individual problems must be carefully checked before climbing.
