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

Climbing Outlook
Site Details
The most popular gabbro bouldering area on the Lleyn Peninsula coast — a remote, beautiful beach setting. The gabbro rock is extremely rough and textured, providing superb friction (bring tape). Semi-tidal: some boulders only accessible at low tide. Landings are generally poor and require multiple pads. Around 42 problems across the grades.
Condition Notes
Non-porous gabbro dries very quickly — can often be climbed shortly after rain. Exceptionally rough texture provides good friction even in marginal conditions but is brutal on skin. Semi-tidal: check tide times as some boulders are only accessible at low tide.
