Mountain Weather brief

Northwest Highlands

Thursday 15 October 2026 · Wester Ross, Assynt and the far northwest

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

A poor day on the tops in the Northwest Highlands, with very strong, gusty winds and burns likely to be in spate.

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

Morning · 08:00–12:00PoorSummit winds around 20-40 mph. Gusts around 45-55 mph are possible on exposed ground. Gusts this strong can make walking very difficult and tiring, with a risk of being blown off your feet. Avoid exposed ridges and edges. Rain is forecast on some hills during this period. Cloud may restrict summit views early on.

Afternoon · 12:00–17:00PoorSummit winds around 20-40 mph. Gusts around 45-55 mph are possible on exposed ground. Gusts this strong can knock you off balance, so take care near edges and on narrow ridges. Rain is forecast on some hills during this period. 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 (900 m)

At around 900 m, expect a south-westerly wind of 35–45 mph, gusting 45–55 mph. Gusts like that are strong enough to make walking very difficult and tiring, with a risk of being blown off your feet. Avoid exposed ridges and edges.

02

Walking impact

Gusts of 45–55 mph are strong enough to make walking very difficult and tiring, with a risk of being blown off your feet. Avoid exposed ridges and edges.

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

High spate risk based on recent and forecast rainfall. Burns and unbridged crossings may become difficult or impassable. 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 is possible on the tops, and it could turn to snow if it is a little colder. Rain for much of the day. Expect 5–10 mm in total, measured as melted water, so any snow would lie deeper. Some forecast models bring rain during the afternoon, while others keep it mostly dry. Drizzle is possible on some hills. On some hills, sleet is possible on the tops. Small temperature changes could shift the mix towards rain or snow. Visibility may drop briefly in showers in parts of the area.

06

Cloud-free summits

Clear-summit estimate: about 35% early, about 65% around midday and about 40% later.

07

Cloud and visibility

The tops are likely to drift in and out of cloud, with the best chance of clear tops in the early afternoon. The cloud base could be as low as 400–700 m early in the morning.

08

Temperature and wind chill

At around 900 m it will be 2 to 6°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 close to summit height.

10

Daylight

Sunrise 07:53, Sunset 18:17, about 10.4 hours daylight.

Overnight · 17:00–08:00Wild campingBetaToo windy for an exposed pitch above about 600 m on some hills (gusts of about 50 mph and around 9 mm of rain). Lower down, a poor night to camp on open ground. 19Poor · 600 m View detailsHide details
Regional night beginning Thursday 15 October 2026

Full regional overnight outlook

Too windy for an exposed pitch above about 600 m on some hills. Lower down, a poor night to camp on open ground. Gusts reach about 50 mph around 900 m and nearer 35 mph around 300 m, enough to damage a tent on open ground. Check the forecast for the hill and height you have in mind, and don't assume lower ground will be sheltered. About 9 mm of rain is forecast overnight. Above about 600 m you'd likely be in cloud for part of the night: damp, and hard to find your way if you need to move. A cold night, down to about 1°C around 900 m. 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.

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 50 mph on exposed ground, making crosswinds an important route consideration. Mapped summit-point geology across the representative hills includes psammite, pelite or semipelite and sandstone or gritstone. 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.
