Five consecutive dry days with strong westerly winds have thoroughly dried the non-porous dolerite surface at Crag Lough. Conditions today are good for climbing, with the rock well-aired despite the north-facing aspect.
Based on weather conditions only — does not cover bird nesting restrictions or other access issues.

Climbing Outlook
Site Details
Dramatic Whin Sill dolerite crag on Hadrian's Wall — a UNESCO World Heritage Site. Unlike sandstone, dolerite is non-porous and can be climbed much sooner after rain, often within hours. North-facing and very exposed on the high ridge. The dense, hard black rock lacks friction when damp but doesn't absorb water. Series of buttresses like wrecked castle towers. Peregrine nesting site in spring.
Condition Notes
Non-porous dolerite can be climbed much sooner after rain than sandstone — often within hours. However, the dense black rock is extremely slippery when wet. Loose blocks and active freeze-thaw at crag bases are a hazard in winter.
