Pillar Rock

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.

Rock moisture, rain and dew

-58.0 points

Wind on the climb

-6.8 points

Extra wind above the crag

-10.0 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 or seeping rock limits the score to 21.1 before rounding.

Final score: 21. 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.
