Confidence: Medium Why?

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

What matters most

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

Morning · 08:00–12:00PoorSummit winds around 15-35 mph. 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. Cloud may restrict summit views early on. Rain is possible during the main walking period, but its timing may shift by several hours.

Afternoon · 12:00–17:00PoorSummit winds around 15-30 mph. Gusts around 30-40 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. Cloud may restrict summit views around midday and later. Rain is possible during the main walking period, but its timing may shift by several hours.

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 15–25 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 saturated after recent rain. Expect boggy paths and rapid runoff if more rain arrives.

04

Spate risk

There could be a spate risk based on recent and 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.

05

Rain and showers

Sleet and snow for much of the day. Expect 2–5 mm in total, measured as melted water, so any snow would lie deeper. Rain is possible during the main walking period, but its timing may shift by several hours. The timing may shift by a few hours. On some hills, sleet or snow is possible on the tops, with the balance depending on temperature. Snow is forecast on some higher tops during the morning and afternoon. The air freezing level is roughly 600 to 800 m above sea level. Snow can fall below this, but its lower limit is uncertain. On some higher summits there is a risk of blizzard conditions during the morning and afternoon, when snow and strong winds coincide. Paths and footprints can quickly disappear beneath falling and blowing snow. Snow may collect in deeper drifts in hollows, behind boulders and on slopes sheltered from the wind. Exposed ground may be scoured while nearby drifts deepen. Wind-loaded slopes can also be avalanche terrain. Check the local avalanche forecast where one is available; this is not an assessment of slope stability.

06

Cloud-free summits

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

07

Cloud and visibility

Expect many summits to be in cloud for most of the day. The cloud base could be as low as 200–500 m early in the morning. 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. Where snow covers the ground, the sky and hillside can merge into a featureless white view, making it difficult to judge slope or direction. Do not rely on following a visible path. Avoid exposed routes if you cannot navigate safely in these conditions, and turn back before visibility deteriorates.

08

Temperature and wind chill

At around 600 m it will be -2 to 2°C, feeling like -8 to -4°C in the wind. Take a hat, gloves, a windproof and a spare warm layer. Pack waterproofs too, and keep a warm layer dry in your pack.

09

Freezing level

The freezing level is around 600–600 m, so it will be below freezing on the tops.

Daylight

Sunrise 07:54, Sunset 16:06, about 8.2 hours daylight.

Overnight · 17:00–08:00Wild campingBetaToo windy for an exposed pitch around 900 m on some hills (gusts of about 35 mph and a frost, down to -1°C). Lower down, a mixed night to camp, mainly because of the wind. 39Poor · 600 m View detailsHide details

Full regional overnight outlook

Too windy for an exposed pitch around 900 m on some hills. Lower down, a mixed night to camp, mainly because of the wind. Gusts reach about 35 mph on open ground, which makes for a noisy, testing night even in a good tent. Check the forecast for the hill and height you have in mind, and don't assume lower ground will be sheltered. A little rain is forecast overnight. A frost up around 600 m, down to about -1°C. The ground will be sodden after recent rain, so pick a firm, well-drained pitch.

The ground is likely to be very wet after recent rain. Expect boggy approaches and choose a durable pitch carefully.

Open-hillside guidance across representative hills. Local shelter, ridges, tent design and the exact pitch can change conditions substantially. Read about sleeping-bag comfort ratings, pitching in strong winds or using the wild-camping forecast.

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 (0/100). 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 sandstone or gritstone and 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.
