Climbing weather, shaped by the terrain.

From sheltered quarries to mountain ridges and sea cliffs, the setting changes what matters. Find the weather information that fits your climbing.

The same weather, different terrain

More than the height of a crag.

A low-level quarry can stay damp in the shade while a breezy face nearby dries quickly. At mountain crags, cloud, exposed approaches and freezing conditions add another layer. At the coast, waves and swell matter even when the rock-weather outlook looks good.

Mountain Weather brings that terrain perspective to climbing at every height. Named-crag forecasts consider the climbing face and, where relevant, open ground above it. Mountain forecasts provide broader exposed-rock guidance. Sea-crag information stays separate because a dry-rock score cannot describe coastal access.

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.

Exposure and gusts

Wind that may feel manageable on a path can be much more consequential on a narrow ridge, slab or committing scramble.

Cloud, ice and thunder

Poor visibility, freezing deposits and thunderstorms can limit an exposed route even when rainfall alone looks modest.

Mountain rock & scrambling

Check the wider mountain conditions.

Choose a summit and expand its climbing-and-scrambling forecast. Consider cloud, wind, freezing conditions and the approach and descent, not just time on the rock.

A broad mountain signal

Mapped rock, without false precision.

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.

Climbing forecast questions

Before committing to rock.

Is this a forecast for a named climbing route or crag?

Popular named crags are split into reviewed OSM cliff sectors where useful geometry exists. Peak and regional cards remain generic hands-on-rock forecasts rather than named-route assessments.

How is the rock-surface description produced?

It combines forecast and recent rainfall with drying conditions and a cautious moisture-response profile for the mapped or reviewed crag rock type. The forecast keeps uncertainty visible where seepage or lingering dampness cannot be resolved.

Are sea cliffs included?

A separate research preview covers selected sea cliffs in Anglesey, Dorset, Devon, Pembrokeshire, Gower and Cornwall using offshore waves, swell, coastal wind and modelled water levels. It does not produce a climbing score or safe-access window, and the inland ranking remains separate.

What weather is most important for scrambling?

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.
