These are direct modelled sunshine hours during daylight, not the probability of sunshine. Cloud cover and summit cloud are assessed separately in the forecast above. The regional median prevents one unusually bright or dull summit cell defining the whole area.

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

01

High-ground wind (900 m)

At around 900 m, expect a south-westerly wind of 20–30 mph, gusting 25–35 mph, strongest first thing and easing later. Gusts like that will be noticeable on ridges and open tops, and you will chill quickly when you stop.

02

Walking impact

Gusts of 25–35 mph will be noticeable on ridges and open tops, and you will chill quickly when you stop.

03

Rain and showers

It should stay dry.

04

Cloud-free summits

Clear-summit estimate: about 85% early, about 60% around midday and about 90% later.

05

Cloud and visibility

The tops should stay mostly clear of cloud. Good spells of sunshine are likely.

06

Temperature and wind chill

At around 900 m it will be 4 to 8°C, feeling like -2 to 2°C in the wind. Take a hat, gloves, a windproof and a spare warm layer.

07

Freezing level

The freezing level is close to summit height.

08

Daylight

Sunrise 08:00, Sunset 18:03, about 10.1 hours daylight.

Regional night beginning Tuesday 20 October 2026

Full regional overnight outlook

Too windy for an exposed pitch up around 900 m on some hills. Lower down, a mixed night to camp, mainly because of the wind. Gusts reach about 40 mph around 900 m and nearer 30 mph around 300 m, which makes for a noisy, testing night even in a good tent. Check the forecast for the hill and height you have in mind, and don't assume lower ground will be sheltered. It should stay dry. Up around 900 m you'd likely be in cloud for part of the night: damp, and hard to find your way if you need to move. Overnight lows of about 4°C at 900 m.

Regional climbing & scrambling outlook

A broad guide to dampness and exposed rock across the area, not a forecast for every crag. Lower, sheltered crags and individual rock types may behave differently.

Conditions for exposed scrambling across the area look good (88/100). Rock is likely to be mostly dry, though local seepage and shaded holds remain unresolved. Gusts may reach about 30 mph on exposed ground, making crosswinds an important route consideration. Mapped summit-point geology across the representative hills includes psammite, pelite or semipelite and granite, gneiss or gabbro. Rock can therefore respond differently to moisture between crags and routes.

Recommended kit for this dayWeather-aware packing prompts, plus your core hillwalking kitView kit

For a day hillwalk, not a complete route-specific checklist. Carry navigation and backup you can use, warm and waterproof layers, suitable footwear, food and water, a headtorch, emergency shelter, first aid and a way to call for help. Snow, ice, technical terrain and overnight trips need additional equipment and skills.
