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

Morning · 08:00–12:00GoodSummit winds around 10-25 mph. Gusts around 25-35 mph are possible on exposed ground. Rain is forecast on some hills during this period. Some forecast models bring rain during the morning, while others keep it mostly dry.

Afternoon · 12:00–17:00MixedSummit winds around 15-25 mph in the early afternoon, strengthening to 25-35 mph later. Gusts around 35-45 mph are possible on exposed ground. Gusts this strong can make walking into it hard work, with buffeting on ridges and edges. Rain is forecast on some hills during this period.

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 southerly wind of 25–35 mph, gusting 35–45 mph, picking up through the day. Gusts like that are strong enough to make walking into it hard work, with buffeting on ridges and edges.

02

Walking impact

Gusts of 35–45 mph are strong enough to make walking into it hard work, with buffeting on ridges and edges.

03

Spate risk

There could be a spate risk based on forecast rainfall. Burns and unbridged crossings may rise quickly. Timing and severity can vary between catchments. Check the peak forecast for the separate rain/runoff periods. Turn back if a crossing looks unsafe.

04

Rain and showers

Rain for much of the day. Expect 5–10 mm in total. Some forecast models bring rain during the morning, while others keep it mostly dry. Drizzle is possible on some hills. Visibility may drop briefly in showers in parts of the area.

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 6 to 10°C, feeling like 0 to 4°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.

08

Freezing level

The freezing level is above the summits.

09

Daylight

Sunrise 07:47, Sunset 18:12, about 10.4 hours daylight.

Full regional overnight outlook

Not a night to camp on the open hill anywhere in this area. Gusts reach about 35 mph on open ground, so peg out well and use the guylines. Check the forecast for the hill and height you have in mind, and don't assume lower ground will be sheltered. About 10 mm of rain is forecast overnight. Overnight lows of about 6°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 poor (27/100). Rain is likely to leave rock wet. Polished slabs, vegetation and drainage lines may be notably worse. Gusts may reach about 40 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.
