Sun and shade

About 4.8 hours of sunshine at the face, mainly before 1pm.

Sun at the face
About 4.8 hours

Approximate sunshine from 08:00 until sunset (about 19:33), allowing for cloud and nearby hills. Individual routes and belays may differ.

How we estimate sun and shade

We use a digital elevation model (a 3D map of the land), the sun's position and the direction the crag faces to estimate when nearby hills or the face itself block the sun. Forecast sunshine and cloud then help estimate how much sunshine is likely. Where terrain or face-direction data are missing, we show general sunshine only.

Vegetation is not mapped in detail, and we cannot resolve small rock features, ledges or overhangs. Hills beyond the sampled 2 km can also change local shade. Sunshine does not guarantee dry or ice-free rock.

Wind, rain and daily score: 08:00–18:00 local time.

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: This climbing signal uses wind on the face and at exposed belays. Open ground above is not included because the represented climbing normally finishes at lower-offs. A precomputed terrain-flow profile refines how the face shelter changes with wind direction. The face is broadly most sheltered in northwesterly flow and most exposed in easterly flow.

Some sectors may be usable, but shaded, polished or seeping sections could remain poor.

Did this match the crag?

A broad sector and surface report is enough; no route-level claim is needed.

Use it as a starting signal

Limestone still needs an on-arrival check.

Usually positive where it is rough and dry, but polished limestone can become very slippery when wet and seepage may linger. Broad crag-level rock context; individual sectors and routes may cross different rock, polish, lichen, superficial deposits or seepage.

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 have not yet been validated against crag-level observations. 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. For this sport-climbing or bouldering venue, wind is shown for the face and exposed belay or landing area; open ground above is not part of the forecast.

A representative climbing-face direction has been checked against a published crag description, but the named point does not resolve individual sectors, route boundaries or exact belay positions. Forecast-grid weather and representative sector geometry only. Check live access information and touch-test the rock before climbing.
