Wind: The mapped crag point does not resolve the cliff face, so shelter on the climb is uncertain. Open ground above may be more exposed, with gusts around 15 mph.

Do not recommend climbing until the rock is completely dry.

A broad sector and surface report is enough; no route-level claim is needed.

Use it as a starting signal

Gritstone still needs an on-arrival check.

The forecast combines recent and expected rain with broad drying, humidity, dew and wind signals. The climb and open ground above the crag are treated separately where the mapped face gives useful shelter context.

Climbing and bouldering use faces around the freestanding crag. A single crag-wide aspect would misrepresent shelter and direct sun. Forecast-grid weather and representative sector geometry only. Check live access information and touch-test the rock before climbing.

Access: Private land with important behaviour, parking and no-night-climbing conditions. RAD currently also carries a time-sensitive block warning; check it before travelling.
