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

01

High-ground wind (500 m)

Westerly around 15 mph at 500 m. Gusts reaching around 20 mph at 500 m, with locally higher values possible on the most exposed tops. Little overall change through the day.

02

Walking impact

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

03

Ground conditions

The ground is likely to be wet after recent rain.

04

Rain and showers

The odd passing shower, otherwise dry.

05

Cloud-free summits

Around 55%. Around 45% early, improving to around 55% later.

06

Cloud and visibility

Cloud bases mostly around 800-1600 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.

07

Temperature and wind chill

Around 10°C at 500 m, feeling like 7°C in the wind.

08

Freezing level

Above the summits.

09

Daylight

Sunrise 06:29 — Sunset 20:01 — about 13.6 hours daylight.

Full regional overnight outlook

Across representative hills, open-hillside camping looks mixed around 300 m (64/100). Open-ground gusts may reach about 30 mph, so sheltered pitches will matter. Little rain is expected, but cloud or condensation could still mean a wet pack-up.

Full regional climbing & scrambling outlook

Conditions for exposed scrambling across the area look mixed (53/100). 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.
