Confidence: High Why?

Forecast models agree on the conditions that matter most to walkers.

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 north-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

Spells of drizzle, mostly in the early afternoon. Visibility may drop briefly in showers in parts of the area.

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

At around 500 m it will be 6 to 10°C, feeling like 2 to 6°C in the wind. A windproof and an extra layer for stops will help. Pack waterproofs too, and keep a warm layer dry in your pack.

07

Freezing level

The freezing level is above the summits.

08

Daylight

Sunrise 07:39, Sunset 18:22, about 10.7 hours daylight.

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 poor (39/100). 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.
