Snow on the hills

Expect snow lying above about 1000 m.

Fresh snow

5 to 10 cm of new snow is forecast today. It will be deeper where the wind piles it into drifts. Rain or a thaw will make the snow wet and heavy, especially in the afternoon. A hard frost afterwards would freeze the surface solid again.

Where the wind will put the snow

Expect strong south-westerly winds, around 31 mph on the tops, to blow the snow about. It will pile into drifts on north and north-east-facing ground, especially below ridges, crags and corrie rims, and in gullies and hollows. Slopes facing into the wind will be scoured, with thinner snow and more rock and ice showing.

Spindrift

Spindrift is likely all day: loose snow lifted by the wind and blown towards the north-east. Heading south-westwards, into it, will be hard work, and visibility can drop sharply in gusts. Goggles make a big difference, keeping the snow out of your eyes so you can still see where you are going. Expect it to stream over crag tops and down north and north-east-facing gullies.

Cornices

Cornices are likely to grow above north and north-east-facing slopes because there will be plenty of new snow to move; a 31 mph wind is strong enough to carry loose snow; and that wind will blow across the ridges from the south-west. A cornice is an overhanging lip of snow built out over the drop by the wind. It can break well back from the edge, so keep well away from it, especially in poor visibility, and do not linger below one, particularly as it warms.

Underfoot

Expect wind-packed snow that carries you in places, with softer pockets in sheltered spots. Conditions will change through the day: thawing intermittently for 8 hours between 13:00 and 24:00.

Frozen turf

Turf is forecast to be frozen to about 6 cm at 1150 m; not frozen at 850 m. Early in the winter the ground still holds summer warmth, so turf can stay soft for longer than the air suggests. Check before relying on it.

Snow to come

On Tuesday: 10 to 20 cm of snow expected on the tops, drifting onto north-west through north to north-east-facing slopes.

Avalanches

Wind-drifted snow on steep slopes is the most common cause of avalanches in British hills, and it can stay unstable for a day or two after the wind drops. Rain or a sharp thaw on lying snow makes wet snow slides more likely on steep slopes. See the note below for where to find an avalanche forecast.

TomorrowWind-drifted snow expected on north and north-east-facing slopes.

Snow lying above about 1000 m. 5 to 10 cm of new snow over the three days to tomorrow. Frozen early, softening through the day. More snow to come: 10 to 20 cm on Tuesday.

Snow on the hills

Expect snow lying above about 1000 m.

Fresh snow

5 to 10 cm of new snow is forecast over the three days to tomorrow. It will be deeper where the wind piles it into drifts. Rain or a thaw will make the snow wet and heavy, especially in the afternoon. A hard frost afterwards would freeze the surface solid again.

Where the wind will put the snow

Expect fresh south-westerly winds, around 22 mph on the tops, to blow the snow about. It will pile into drifts on north and north-east-facing ground, especially below ridges, crags and corrie rims, and in gullies and hollows. Slopes facing into the wind will be scoured, with thinner snow and more rock and ice showing.

Cornices

Cornices are likely to grow above north and north-east-facing slopes because there will be plenty of new snow to move; a 22 mph wind is strong enough to carry loose snow; and that wind will blow across the ridges from the south-west. A cornice is an overhanging lip of snow built out over the drop by the wind. It can break well back from the edge, so keep well away from it, especially in poor visibility, and do not linger below one, particularly as it warms.

Underfoot

Expect a frozen crust early, softening through the day into heavier, wetter snow. Conditions will change through the day: thawing until 06:00, then refreezing.

Frozen turf

Turf is forecast to be frozen to about 8 cm at 1150 m; only a thin frozen crust at 850 m. Early in the winter the ground still holds summer warmth, so turf can stay soft for longer than the air suggests. Check before relying on it.

Snow to come

On Tuesday: 10 to 20 cm of snow expected on the tops, drifting onto north-west through north to north-east-facing slopes.

Avalanches

Mon 16 NovFirm, frozen snow expected: good for crampons, but a slip can be hard to stop.

Snow lying above about 1000 m. 5 to 10 cm of new snow over the three days to Monday. Firm, frozen snow underfoot: crampons and an ice axe matter. More snow to come: 10 to 20 cm on Tuesday.

It can break well back from the edge, so keep well away from it, especially in poor visibility, and do not linger below one, particularly as it warms.

Underfoot

Expect firm névé: old snow that has thawed and refrozen. Crampons grip it well, but a slip on it can be very hard to stop, so an ice axe matters.

Frozen turf

Turf is forecast to be frozen to about 10 cm at 1150 m; frozen to about 4 cm at 850 m. Early in the winter the ground still holds summer warmth, so turf can stay soft for longer than the air suggests. Check before relying on it.

Snow on the hills

Expect snow lying above about 400 m. Drifts will be deepest on west through north-west to north-east-facing slopes, where soft snow may be knee-deep or more in hollows and gully tops.

Fresh snow

10 to 20 cm of new snow is forecast at around 1150 m on Tuesday. Expect it to be soft and deep in places, and slow going. New snow takes a day or two to settle. Rain or a thaw will make the snow wet and heavy, especially in the afternoon. A hard frost afterwards would freeze the surface solid again.

Where the wind will put the snow

Expect strong southerly winds, around 37 mph on the tops, to blow the snow about. It will pile into drifts on north-west through north to north-east-facing ground, especially below ridges, crags and corrie rims, and in gullies and hollows. Slopes facing into the wind will be scoured, with thinner snow and more rock and ice showing. Older drifts from earlier winds are also likely on west-facing slopes.

Spindrift

Spindrift is likely all day: loose snow lifted by the wind and blown towards the north. Heading southwards, into it, will be hard work, and visibility can drop sharply in gusts. Goggles make a big difference, keeping the snow out of your eyes so you can still see where you are going. Expect it to stream over crag tops and down north-west through north to north-east-facing gullies.

Cornices

Cornices are likely to grow above north-west through north to north-east-facing slopes because there will be plenty of new snow to move; a 37 mph wind is strong enough to carry loose snow; and that wind will blow across the ridges from the south. A cornice is an overhanging lip of snow built out over the drop by the wind. It can break well back from the edge, so keep well away from it, especially in poor visibility, and do not linger below one, particularly as it warms.

Underfoot

Expect new, loose snow on top, with hard going in deeper drifts.

Frozen turf

Turf is forecast to be frozen to about 11 cm at 1150 m; frozen to about 4 cm at 850 m. Early in the winter the ground still holds summer warmth, so turf can stay soft for longer than the air suggests. Check before relying on it.

Avalanches

As a general rule, most avalanches happen during heavy snowfall or in the day or two after it, while the new snow is still settling. Wind-drifted snow on steep slopes is the most common cause of avalanches in British hills, and it can stay unstable for a day or two after the wind drops. Rain or a sharp thaw on lying snow makes wet snow slides more likely on steep slopes. See the note below for where to find an avalanche forecast.

Heading south-eastwards, into it, will be hard work, and visibility can drop sharply in gusts. Goggles make a big difference, keeping the snow out of your eyes so you can still see where you are going. Expect it to stream over crag tops and down west through north-west to north-facing gullies.

Cornices

Cornices are likely to grow above west through north-west to north-facing slopes because there will be plenty of new snow to move; a 41 mph wind is strong enough to carry loose snow; and that wind will blow across the ridges from the south-east. A cornice is an overhanging lip of snow built out over the drop by the wind. It can break well back from the edge, so keep well away from it, especially in poor visibility, and do not linger below one, particularly as it warms.

Underfoot

Expect new, loose snow on top, with hard going in deeper drifts.

Frozen turf

Turf is forecast to be frozen to about 7 cm at 1000 m; not frozen at 700 m. Early in the winter the ground still holds summer warmth, so turf can stay soft for longer than the air suggests. Check before relying on it.

Snow on the hills

Expect snow lying above about 1000 m. Drifts will be deepest on north-east-facing slopes, where soft snow may be knee-deep or more in hollows and gully tops.

Fresh snow

Where the wind will put the snow

Expect gale-force south-westerly winds, around 44 mph on the tops, to blow the snow about. It will pile into drifts on north through north-east to east-facing ground, especially below ridges, crags and corrie rims, and in gullies and hollows. Slopes facing into the wind will be scoured, with thinner snow and more rock and ice showing.

Spindrift

Cornices

Cornices are likely to grow above north-east-facing slopes because there will be plenty of new snow to move; a 44 mph wind is strong enough to carry loose snow; and that wind will blow across the ridges from the south-west. A cornice is an overhanging lip of snow built out over the drop by the wind. It can break well back from the edge, so keep well away from it, especially in poor visibility, and do not linger below one, particularly as it warms.

Underfoot

Expect wet, heavy snow. It balls up under crampons and can slide on steep ground. Conditions will change through the day: thawing from 10:00 onward after a frozen night.

Frozen turf

Turf is not expected to be frozen, so frozen-turf scrambles and winter routes will not be in condition.

Snow to come

On Tuesday: 20 to 30 cm of snow expected on the tops, drifting onto west through north-west to north-facing slopes.

Avalanches

TomorrowWind-drifted snow expected on north through north-east to east-facing slopes.

Snow lying on the tops. 5 to 10 cm of new snow over the three days to tomorrow. Firm, frozen snow underfoot: crampons and an ice axe matter. More snow to come: 20 to 30 cm on Tuesday.

Snow on the hills

Expect snow lying on the tops.

Fresh snow

Where the wind will put the snow

Expect strong south-westerly winds, around 39 mph on the tops, to blow the snow about. It will pile into drifts on north through north-east to east-facing ground, especially below ridges, crags and corrie rims, and in gullies and hollows. Slopes facing into the wind will be scoured, with thinner snow and more rock and ice showing.

Spindrift

Spindrift is likely in the afternoon: loose snow lifted by the wind and blown towards the north-east. Heading south-westwards, into it, will be hard work, and visibility can drop sharply in gusts. Goggles make a big difference, keeping the snow out of your eyes so you can still see where you are going.

It can break well back from the edge, so keep well away from it, especially in poor visibility, and do not linger below one, particularly as it warms.

Underfoot

Expect firm névé: old snow that has thawed and refrozen. Crampons grip it well, but a slip on it can be very hard to stop, so an ice axe matters. Conditions will change through the day: thawing until 04:00, then refreezing.

Frozen turf

Turf is forecast to be frozen to about 3 cm at 1000 m; not frozen at 700 m. Early in the winter the ground still holds summer warmth, so turf can stay soft for longer than the air suggests. Check before relying on it.

These are direct modelled sunshine hours during daylight, not the probability of sunshine. Cloud cover and summit cloud are assessed separately in the forecast above. The regional median prevents one unusually bright or dull summit cell defining the whole area.

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

Morning · 08:00–12:00MixedSummit winds around 10-30 mph. Gusts around 30-40 mph are possible on exposed ground. Summit cloud is more persistent early in this period, with better prospects later. Rain is possible during the main walking period, but its timing may shift by several hours.

Afternoon · 12:00–17:00GoodSummit winds around 15-30 mph. Gusts around 30-40 mph are possible on exposed ground. Summit cloud is more likely to break 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.

High-ground wind (900 m)

At around 900 m, expect an easterly wind of 20–30 mph, gusting 25–35 mph. Gusts like that will be noticeable on ridges and open tops, and you will chill quickly when you stop.

Walking impact

Gusts of 25–35 mph will be noticeable on ridges and open tops, and you will chill quickly when you stop.

Rain and showers

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.

Cloud-free summits

Clear-summit estimate: about 25% early, about 55% around midday and about 55% later.

Cloud and visibility

The tops are likely to drift in and out of cloud, with the best chance of clear tops mid-morning. The cloud base could be as low as 700–1000 m mid-morning. The air should be clear, so expect far-reaching views whenever the tops come out of the cloud.

Temperature and wind chill

At around 900 m it will be -4 to 0°C, feeling like -12 to -8°C in the wind. Hat, gloves and a warm insulated layer are essential, with extra warmth for stops.

Freezing level

The freezing level is around 500–800 m, so it will be below freezing on the tops.

Daylight

Sunrise 08:05, Sunset 16:02, about 8.0 hours daylight.

Differences across the area

More sunshine is likely around the western hills than the eastern hills. This is a broad-area estimate, not sunshine on every summit.

Overnight · 17:00–08:00Wild campingBetaAcross these hills, a mixed night to camp, mainly because of the wind: gusts of about 35 mph and a frost, down to -3°C. 54Mixed · 600 m View detailsHide details

Regional night beginning Wednesday 18 November 2026

Full regional overnight outlook

Across these hills, a mixed night to camp, mainly because of the wind. Gusts reach about 35 mph around 900 m and nearer 25 mph around 300 m, which makes for a noisy, testing night even in a good tent. Look for shelter from the northeast. It should stay dry. A frost up around 900 m, down to about -3°C.

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 (21/100). Some rock may remain damp or incompletely dried, especially in shade and seepage lines. Gusts may reach about 30 mph on exposed ground, making crosswinds an important route consideration. Mapped summit-point geology across the representative hills includes psammite, pelite or semipelite, granite, gneiss or gabbro and volcanic rock. 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.
