Mountain Weather brief

Dartmoor

Wednesday 2 September 2026 · The high moor and tors

Conservative regional grades across representative summits, so one sheltered hill does not overstate the wider area.

01

High-ground wind (500 m)

Southwesterly around 15 mph at 500 m. Gusts reaching around 20 mph at 500 m, with locally higher values possible on the most exposed tops. Starting nearer 5 mph, then strengthening toward 15 mph later.

02

Walking impact

Noticeable on exposed ground, but unlikely to impede most walking.

03

Rain and showers

The odd passing shower, otherwise dry. Forecast models disagree on when the rain may arrive.

04

Cloud-free summits

Around 50%.

05

Cloud and visibility

Cloud bases mostly around 600-1600 m. Bases should tend to lift as the day goes on. Cloud bases are likely to remain high, but some forecast models are much cloudier, so more extensive summit cloud remains a credible outcome. Cloud is likely to come and go on the higher summits; breaks may be useful but not dependable.

06

Temperature and wind chill

Around 11°C at 500 m, feeling like 8°C in the wind.

07

Freezing level

Above the summits.

08

Daylight

Sunrise 06:30 — Sunset 19:59 — about 13.5 hours daylight.

Full regional climbing & scrambling outlook

Conditions for exposed scrambling across the area look poor (35/100). Rain is likely to leave rock wet; polished slabs, vegetation and drainage lines may be notably worse. Mapped summit-point geology across the representative hills includes granite, gneiss or gabbro; moisture response can therefore vary substantially between crags and routes.
