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.
Based on weather conditions only — does not cover bird nesting restrictions or other access issues.

Climbing Outlook
Site Details
A strong contender for the best bouldering in North Wales, on a hidden plateau above the Ogwen Valley. Around 78 problems (V4–V12) on superb volcanic rock. The perched position catches all available wind, so it dries quickly after rain. Steep 15-minute scree approach keeps crowds down. Quality of rock is exceptional.
