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 20 mph.

Wet or seeping sections are likely; choose another crag or wait for direct observations.

Use it as a starting signal

Limestone 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.

The long escarpment includes north-, northeast-, northwest- and southwest-facing sectors. One representative aspect would be misleading, so sector shelter and sun remain unresolved. Forecast-grid weather and representative sector geometry only. Check live access information and touch-test the rock before climbing.

Access: RAD currently carries time-sensitive user-attention and sector restriction information; the live page governs.
