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

01

High-ground wind (900 m)

Northeasterly 5-10 mph at 900 m. Gusts reaching around 10 mph at 900 m, with locally higher values possible on the most exposed tops. Little overall change through the day.

02

Walking impact

Little effect on walking, although exposed tops may still feel chilly.

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%. Around 35% early, improving to around 55% later.

05

Cloud and visibility

Cloud bases mostly around 700-1200 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.

06

Temperature and wind chill

Around 8°C at 900 m, feeling like 6°C in the wind.

07

Freezing level

Above the summits.

08

Daylight

Sunrise 06:13 — Sunset 20:27 — about 14.2 hours daylight.

Across representative exposed-rock terrain

Full regional climbing & scrambling outlook

Conditions for exposed scrambling across the area look poor (36/100). 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 psammite, pelite or semipelite and sandstone or gritstone; moisture response can therefore vary substantially between crags and routes.
