Check access before travelling. A good weather score does not mean the crag is open. Restrictions are not checked live here.

Scores compare weather suitability for climbing, not safety or guaranteed dry rock. The daily score averages the represented sectors; check their details below. How climbing scores work.

Uncertain

48

Do not climb wet sandstone or gritstone. Wait until the rock is fully dry.

Inadvisable to climb while wet.Some porous rocks, including sandstone and gritstone, can be weakened by moisture. Climbing on them while wet can damage or break holds. BMC wet-rock guidance.

We estimate how quickly the rock may dry using the amount and timing of recent rain, then assess each following hour for sunshine, shade, wind, temperature and humidity. Rock type, seepage tendency, season and dew risk also affect the result. Sheltered holds and drainage lines can stay damp after exposed rock dries.

The dry-spell label counts time since an hour with at least 0.2 mm of modelled rain. Lighter traces remain visible in the chart. Rainfall is modelled, not measured at the crag. For a future climbing day, some or all of its preceding rain is still a forecast. Totals include snow as its equivalent amount of water. Times are local.

Shelter can reduce wind-driven rain, but also the breeze that helps rock dry. Rain totals are not reduced for face direction, and shelter never guarantees dry holds.

Rain on the face: Rain is likely to blow onto this face, wetting exposed holds. Allow for drying after it clears. Shelter does not override the warning to avoid climbing wet rock.

Why this score?

This is a weather-suitability score, not a percentage chance of dry rock or a dedicated bouldering-friction rating. Cold, dry conditions can suit friction but still make exposed climbing and belaying uncomfortable.

Starting score
100.0 points
Rain interruption allowance
-6.2 points
Wind on the climb
-23.7 points

Starting at 100, we deduct for conditions that could spoil the session. Wind uses the larger deduction from sustained wind or gusts, not both added together. A small amount of forecast rain still counts even when the rock should dry quickly. The rain allowance only tops up the moisture deduction, so the same rain is not counted twice.

These are practical suitability weights, not measured probabilities or a safety rating. A high score does not guarantee dry holds or comfortable wind at every climb.

Light wind up to 10 mph carries no deduction. Above that, small comfort deductions build gradually. Where topping out or top-belaying is relevant, stronger wind above the crag also counts. Recent rain can leave a small allowance for damp patches even after good drying; this reduces with drying time and only tops up other moisture deductions.

Wet-rock conservation limits the score to 48.0 before rounding.

Final score: 48. Contributions are rounded. Low scores are bounded at zero; conservation and weather warnings still apply. Midges are shown separately.

Surface drying does not rule out seepage. We use rain over the preceding 72 hours and a broad rock-type seepage allowance. We do not model individual cracks, peat drainage or river levels. Rock may remain wet along drainage lines after exposed surfaces dry.

Rain history is modelled, not measured at the crag. Dew uses an estimated rock temperature. Tree shade is estimated broadly; wind and humidity beneath individual canopies are unresolved. These are broad signals, not observations of a particular route.

Sun and shade

About 0.7 hours of sunshine at the face.

Sun at the face
About 0.7 hours

Approximate sunshine from 08:00 until sunset (about 18:15), 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 bouldering signal uses wind at the rock and exposed landings. Open ground above is not part of the represented activity. A precomputed terrain-flow profile refines how the face shelter changes with wind direction. The face is broadly most sheltered in northeasterly flow and most exposed in southwesterly flow.

Season: Spring and autumn drying can remain slow when rock is cold, shaded or humid.

Climbing is inadvisable until the rock is completely dry.

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

Sandstone still needs an on-arrival check.

Often grippy when dry, but wet sandstone can lose strength and may be damaged by climbing. Avoid it while saturated and allow shaded walls, pockets and seepage lines time to dry. 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.
