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 an easterly wind of 15–25 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 60% early, about 60% around midday and about 55% later.

05

Cloud and visibility

The tops are likely to drift in and out of cloud, with the best chance of clear tops early on. The air should be clear, so expect far-reaching views whenever the tops come out of the cloud.

06

Temperature and wind chill

At around 500 m it will be 2 to 6°C, feeling like -6 to -2°C in the wind. Take a hat, gloves, a windproof and a spare warm layer.

07

Freezing level

The freezing level is above the summits.

08

Daylight

Sunrise 07:38, Sunset 16:23, about 8.8 hours daylight.

Full regional overnight outlook

Across these hills, a mixed night to camp, mainly because of the rain. Gusts reach about 25 mph on open ground, so peg out well and use the guylines. Look for shelter from the southeast. Some light rain is forecast overnight. Overnight lows of about 4°C at 300 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 (77/100). Likely to stay mostly dry, but patchy rain remains possible. Exposed rock could become damp or slippery. Gusts may reach about 30 mph on exposed ground, making crosswinds an important route consideration. 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.
