60/100

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

01

High-ground wind (600 m)

Westerly around 20 mph at 600 m. Gusts reaching around 25 mph at 600 m, with locally higher values possible on the most exposed tops. Starting nearer 10 mph, then strengthening toward 15 mph later.

02

Walking impact

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

03

Thunderstorms

Thunderstorms are possible during the morning. Keep an escape route from exposed ridges and descend if thunder develops.

04

Ground conditions

The ground is likely to be saturated after recent rain. Expect boggy paths and rapid runoff if more rain arrives.

05

Rain and showers

Showers or spells of rain at times. The heaviest rain is expected early in the day.

06

Cloud-free summits

Around 40%. Around 30% early, improving to around 60% later.

07

Cloud and visibility

Cloud bases mostly around 600-1000 m. Bases should tend to lift as the day goes on. Cloud is likely to come and go on the higher summits; breaks may be useful but not dependable.

08

Temperature and wind chill

Around 9°C at 600 m, feeling like 6°C in the wind.

09

Freezing level

Above the summits.

Daylight

Sunrise 06:18 — Sunset 20:12 — about 13.9 hours daylight.

Full regional overnight outlook

Across representative hills, open-hillside camping looks poor around 600 m (42/100). A wet night is likely, with around 8 mm indicated between pitching and packing up.

The ground is likely to be very wet after recent rain; expect boggy approaches and choose a durable pitch carefully.

Open-hillside guidance across representative hills. Local shelter, ridges, tent design and the exact pitch can change conditions substantially. Read about sleeping-bag comfort ratings, pitching in strong winds or using the wild-camping forecast.

Across representative exposed-rock terrain

Full regional climbing & scrambling outlook

Conditions for exposed scrambling across the area look very poor (0/100). Rain is likely to leave rock wet; polished slabs, vegetation and drainage lines may be notably worse. Gusts may reach about 25 mph on exposed ground, making crosswinds an important route consideration. Mapped summit-point geology across the representative hills includes sandstone or gritstone and granite, gneiss or gabbro; moisture response can therefore vary substantially between crags and routes.
