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

01

High-ground wind (900 m)

Westerly around 35 mph at 900 m. Gusts reaching around 50 mph at 900 m, with locally higher values possible on the most exposed tops. Little overall change through the day.

02

Walking impact

Arduous in exposure, with buffeting and difficult progress into the wind.

03

Thunderstorms

A moderate thunderstorm risk is indicated from the morning into the evening. Avoid committing to exposed summits or ridges while storms are building or nearby.

04

Ground conditions

The ground is likely to be wet after recent rain.

05

Spate risk

There could be a spate risk based on forecast rainfall. Burns and unbridged crossings may rise quickly. Crossing risk is expected throughout the day, continuing overnight and easing after around 03:00 the following morning. Turn back if a crossing looks unsafe.

06

Rain and showers

Persistent rain for much of the day.

07

Cloud-free summits

Around 20%.

08

Cloud and visibility

Cloud bases mostly around 300-600 m. Most higher summits are likely to be in cloud for much of the day, with only brief or isolated breaks.

09

Temperature and wind chill

Around 7°C at 900 m, feeling like 1°C in the wind.

10

Freezing level

Above the summits.

Daylight

Sunrise 06:31 — Sunset 20:14 — about 13.7 hours daylight.

Regional night beginning Friday 4 September 2026

Full regional overnight outlook

Across representative hills, open-hillside camping looks poor around 600 m (32/100). Higher pitches look less comfortable, with colder, cloudier or more exposed conditions. Open-ground gusts may reach about 50 mph, so sheltered pitches will matter. Some overnight rain is likely, so expect a damp pitch or pack-up.

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 50 mph on exposed ground, making crosswinds an important route consideration. Mapped summit-point geology across the representative hills includes granite, gneiss or gabbro; moisture response can therefore vary substantially between crags and routes.
