Possible · 20/100
Experimental wind estimate: Shelter at individual holds and belays is unresolved. Strong gusts may differ substantially; summit-station validation does not establish crag-level accuracy.
Wind: The cliff face and open ground above have broadly similar wind exposure.
Midges: Midges are possible at sheltered belays when the breeze drops. The face has light-wind spells when midges can remain active around stationary climbers. Cloudier conditions favour activity.
Drying is plausible, but confirm the rock at the crag before committing.

Experimental wind estimate: Shelter at individual holds and belays is unresolved. Strong gusts may differ substantially; summit-station validation does not establish crag-level accuracy.
Wind: The mapped face may offer some shelter from the southwesterly wind, but open ground above the crag is more exposed, with gusts around 31 mph.
Midges: Few midges are expected on the face, though the most sheltered corners may differ. The face breeze should suppress most activity during the climbing window. Cloudier conditions favour activity. Rain may suppress flying while it falls, despite keeping the habitat damp.
Wet or seeping sections are likely; choose another crag or wait for direct observations.

Wind: The mapped face may offer some shelter from the westerly wind, but open ground above the crag is more exposed, with gusts around 44 mph.
Midges: Few midges are expected on the face, though the most sheltered corners may differ. Recent rain should keep nearby breeding ground damp. The face breeze should suppress most activity during the climbing window. Rain may suppress flying while it falls, despite keeping the habitat damp.

Use it as a starting signal
Mica schist still needs an on-arrival check.
Climbing window: 08:00–18:00 local time. Rain is model-grid precipitation, including any snow as water equivalent; nearby crags can share it. Aspect and terrain refine wind and drying, not cliff-by-cliff rainfall or rain shadows.
Crag drying and sheltered-wind estimates are an unvalidated beta. Published summit checks are not a validation of low crags, woodland or individual belays.
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.
Broad south-facing crag, not a route or belay map. Representative elevation is approximate; walls extend over a range of heights. Forecast-grid weather and representative sector geometry only. Check live access information and touch-test the rock before climbing.
