Gabbro at Porth Ysgo has had roughly 24 hours of drying since the last trace precipitation (0.1mm late on April 12th) and over a day since the more significant 0.7mm on April 12th, with moderate winds aiding surface drying. However, high ambient humidity (~80%) and a very wet recent period mean sea spray and residual dampness on lower boulders is possible — a visual check on arrival is warranted before committing.

Today is dry with moderate humidity (72%) after a wet recent period, and the cave roof means the rock itself is unlikely to be directly wet. However, the sheltered north-facing aspect and recent frequent rainfall mean humidity-driven greasiness is a real concern — conditions should be checked on arrival before committing to hard problems.

The last significant rain was the 47.5mm deluge on April 11, followed by lighter showers on April 12 (7.8mm total, last drops around 16:00). Today (April 13) has been dry so far with moderate wind and dropping humidity — the exposed rhyolite should be drying, but given the enormous recent saturation (71mm in 7 days) and the 400m altitude, residual seepage and damp patches in sheltered spots are very likely. Climbers should visually inspect holds before committing.

After 2.2mm of rain on April 12 (mostly in the early hours) and a full dry day since, surface limestone at Angel Bay may be approaching climbable condition, but the north-facing aspect, recent intermittent wet spells, and moderate humidity mean pockets and seepage lines could still be damp. Climbers should visually and physically assess the rock before committing.

The last rain fell in the early hours of April 12th, giving roughly 30+ hours of drying by this afternoon, but the preceding weeks have been exceptionally wet (190mm in 28 days) and humidity remains high at 81%. The exposed aspect and moderate winds will have helped surface drying on this non-porous rhyolite, but seepage, residual dampness in cracks, and the NW aspect's poor sun exposure make on-site assessment essential.

After a very wet spell culminating in 40.5mm on April 11th and 5.5mm on April 12th, today is the first fully dry day with moderate winds and dropping humidity. The rhyolite surfaces may have dried sufficiently given the exposed aspect and wind, but residual dampness in sheltered spots and seepage from the saturated hillside above is likely — climbers should visually check conditions on arrival.

The boulders have had roughly 18 hours of dry weather following 7.2mm of rain on April 12, with moderate wind aiding surface drying. While rhyolite dries relatively quickly and the surface may be dry on exposed faces, the persistently high humidity (80%) and lack of strong sun mean sheltered or north-facing surfaces could still be damp — a visual check on arrival is essential before committing to climb.

Today is the first dry day after a very wet week (51.8mm in 7 days), with the last rain falling early on April 12. The south-facing aspect and moderate winds should have dried exposed surfaces, but seepage, sheltered areas, and high ambient humidity mean conditions need on-ground verification before committing to climb.
