Confidence: Medium Why?

Uncertainty over rain amounts and timing. Uncertainty over sky cloud cover and sunshine.

What matters most

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.

Overnight forecast: 17:00–08:00 (UK local time), in Wild camping below.

Morning · 08:00–12:00MixedSummit winds around 10-20 mph. Gusts around 20-30 mph are possible on exposed ground. Rain is forecast on some hills during this period. Rain is possible during the main walking period, but its timing may shift by several hours.

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

01

High-ground wind (500 m)

At around 500 m, expect a south-westerly wind of 15–25 mph, gusting 20–30 mph. A wind like that will be noticeable on ridges and open tops, and you will chill quickly when you stop.

02

Walking impact

A steady wind of 15–25 mph will be noticeable on ridges and open tops, and you will chill quickly when you stop.

03

Rain and showers

Drizzle at first, clearing by mid-morning. Rain is possible during the main walking period, but its timing may shift by several hours. The timing may shift by a few hours.

04

Cloud-free summits

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

05

Cloud and visibility

The tops should stay clear of cloud all day. The air should be clear too, so expect far-reaching views from the tops.

06

Temperature and wind chill

Around 13°C at 500 m, feeling like 11°C in the wind.

07

Freezing level

The freezing level is above the summits.

08

Daylight

Sunrise 07:32, Sunset 18:30, about 11.0 hours daylight.

Regional night beginning Monday 12 October 2026

Full regional overnight outlook

Not a night to camp on the open hill anywhere in this area. Gusts reach about 35 mph on open ground, so peg out well and use the guylines. Check the forecast for the hill and height you have in mind, and don't assume lower ground will be sheltered. About 10 mm of rain is forecast overnight. Overnight lows of about 11°C at 300 m. The moon won't be up after dark, so there will be no moonlight.

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 very poor (11/100). 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. 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.
