Use it as a starting signal
Soft sandstone 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.
A representative climbing-face direction has been checked against a published crag description, but the named point does not resolve individual sectors, route boundaries or exact belay positions. Forecast-grid weather and representative sector geometry only. Check live access information and touch-test the rock before climbing.
Access: BMC-owned soft sandstone: follow the Southern Sandstone code, use only permitted climbing styles and do not climb until the rock is fully dry.
