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

01

High-ground wind (900 m)

Westerly around 15 mph at 900 m. Gusts reaching around 20 mph at 900 m, with locally higher values possible on the most exposed tops. Strongest early (around 15 mph), easing toward 5 mph later.

02

Walking impact

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

03

Rain and showers

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

04

Cloud-free summits

Around 30%. Around 10% early, improving to around 50% later.

05

Cloud and visibility

Cloud bases mostly around 900-1200 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 5°C at 900 m, feeling like 1°C in the wind.

07

Freezing level

Above the summits.

08

Across representative exposed-rock terrain

Full regional climbing & scrambling outlook

Conditions for exposed scrambling across the area look poor (25/100). 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.
