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 20–30 mph, gusting 25–35 mph. 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

Ground conditions

The ground is likely to be wet after recent rain.

04

Rain and showers

Drizzle sets in during the early afternoon.

05

Cloud-free summits

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

06

Cloud and visibility

The tops should stay clear of cloud all day.

07

Temperature and wind chill

At around 500 m it will be 4 to 8°C, feeling like 0 to 4°C in the wind. A windproof and an extra layer for stops will help.

08

Freezing level

The freezing level is above the summits.

09

Daylight

Sunrise 07:49, Sunset 18:10, about 10.3 hours daylight.

Full regional overnight outlook

Across these hills, a mixed night to camp, mainly because of the wind. Gusts reach about 30 mph on open ground, so peg out well and use the guylines. Look for shelter from the southwest. A little rain is forecast overnight. Overnight lows of about 7°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 mixed (53/100). Rain is likely to leave rock wet. Polished slabs, vegetation and drainage lines may be notably worse. 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.
