Confidence: Medium Why?

Uncertainty over rain amounts and timing. Uncertainty over high-ground wind strength. Uncertainty over sky cloud cover and sunshine.

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

Morning · 08:00–12:00MixedSummit winds around 0-10 mph. Gusts around 10-20 mph are possible on exposed ground. Cloud may restrict summit views early on. Rain is possible during the morning, but forecast models disagree on whether it will fall. Rain is possible during the main walking period, but its timing may shift by several hours.

Afternoon · 12:00–17:00MixedSummit winds around 5-15 mph. Gusts around 15-25 mph are possible on exposed ground. Rain is forecast on some hills during this period. Cloud may restrict summit views around midday and later. Some forecast models bring rain during the afternoon, while others keep it mostly dry.

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 10–20 mph, gusting 15–25 mph, picking up through the day.

02

Walking impact

Noticeable on exposed ground, but unlikely to impede most walking.

03

Ground conditions

The ground is likely to be wet after recent rain.

04

Rain and showers

A little rain at times. Rain is possible during the morning and afternoon, but forecast models disagree on whether it will fall. Some forecast models bring rain during the afternoon, while others keep it mostly dry. Rain is possible during the main walking period, but its timing may shift by several hours. The timing may shift by a few hours.

05

Cloud-free summits

Clear-summit estimate: about 15% early, about 10% around midday and about 10% later.

06

Cloud and visibility

Expect many summits to be in cloud for most of the day. The cloud base could be as low as 300–600 m around midday. In cloud you'll be finding your way without landmarks, so carry navigation you trust and know how to use, with a backup such as a spare battery or a map and compass. Any sunshine is more likely on lower ground than on the summits.

07

Temperature and wind chill

At around 500 m it will be 2 to 6°C, feeling like -4 to 0°C in the wind. Take a hat, gloves, a windproof and a spare warm layer.

08

Freezing level

The freezing level is above the summits.

09

Daylight

Sunrise 07:36, Sunset 16:24, about 8.8 hours daylight.

Full regional overnight outlook

Across these hills, a mixed night to camp, mainly because of the cold. Gusts reach about 25 mph on open ground, so peg out well and use the guylines. Look for shelter from the east. It should stay dry. A cold night, down to about 2°C around 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 very poor (15/100). 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.
