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

01

High-ground wind (600 m)

At around 600 m, expect an easterly wind of 0–10 mph, gusting 5–15 mph.

02

Walking impact

Little effect on walking, although exposed tops may still feel chilly.

03

Ground conditions

The ground is likely to be wet after recent rain.

04

Rain and showers

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 600 m it will be 0 to 4°C, feeling like -4 to 0°C in the wind. It turns milder through the day. Take a hat, gloves, a windproof and a spare warm layer.

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 excellent (94/100). Rock is likely to be mostly dry, though local seepage and shaded holds remain unresolved. Mapped summit-point geology across the representative hills includes sandstone or gritstone and granite, gneiss or gabbro. Rock can therefore respond differently to moisture between crags and routes.

Damp sandstone and gritstone can feel greasy, and saturated sandstone may be weakened, so let the rock dry fully.granite, gneiss or gabbro 14% 1 representative summitGenerally grippy when dry and often still positive when damp, but wet slabs, lichen, polish and drainage lines can remain slippery.

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.
