Surface and rock context
Forecast and recent rain are balanced against drying conditions, with broad mapped geology kept separate from unresolved route-level seepage, polish and drainage.
Rock and scrambling guidance that brings surface state, rain, exposed wind and serious hazards into one mountain forecast.
A dry icon does not guarantee dry rock. Recent rainfall, low cloud, weak drying, seepage and shade can all leave mountain rock damp after precipitation ends. Our climbing and scrambling conditions forecast combines the available weather signals with the BGS-mapped summit bedrock and a cautious moisture-response family.
The result covers the normal daytime period around an individual summit or mountain area. It includes a broad surface state, rain total, exposed gusts and major hazards such as thunder or wintry deposits. BGS geology improves the context; it does not resolve the exact rock, polish, lichen or drainage on a named line.
Forecast and recent rain are balanced against drying conditions, with broad mapped geology kept separate from unresolved route-level seepage, polish and drainage.
Wind that may feel manageable on a path can be much more consequential on a narrow ridge, slab or committing scramble.
Poor visibility, freezing deposits and thunderstorms can limit an exposed route even when rainfall alone looks modest.

Each peak can include its summit-point lithology from BGS Geology 50K. Regional forecasts describe the mix across representative summits instead of pretending an entire national park has one rock type. The mapped family helps distinguish moisture-sensitive sandstone, seepage-prone limestone, volcanic rock, granite and varied metamorphic rocks.
It remains generic exposed-rock guidance. Route grade, the actual geology under each hold, polish, vegetation, aspect, shade, drainage and escape options can make a named climb or scramble substantially easier or harder. Use a route guide, recent local observations and your own assessment at the rock.
Not yet. The current forecast describes generic exposed hands-on-rock terrain around a peak or mountain area. BGS summit-point bedrock is included where available, but a route can cross different geology, drainage, shade, polish and seepage.
It combines forecast and recent rainfall with drying conditions and a cautious moisture-response profile for the BGS-mapped rock family, while keeping uncertainty visible where seepage or lingering dampness cannot be resolved.
Wet or icy rock, serious gusts, thunder and poor visibility can each dominate the result. The score is capped when a major hazard is present rather than averaged away.
