Use it as a starting signal
Granite 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.
Reviewed OSM cliff ways and broad face aspects, not route boundaries, exact belay positions or a climbing topo. Forecast-grid weather and representative sector geometry only. Check live access information and touch-test the rock before climbing.
Access: Check current landowner and BMC access information, seasonal restrictions and local notices before travelling.
