Snow on the hills

Expect little or no lying snow. Old patches may survive in sheltered gullies.

Frozen turf

Turf is forecast to be frozen to about 3 cm at 800 m; not frozen at 500 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 north-west through north 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 800 m on Tuesday. Expect it to be soft and deep in places, and slow going. New snow takes a day or two to settle.

Where the wind will put the snow

Expect gale-force southerly winds, around 48 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 from the morning into the afternoon: 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 and north-facing slopes because there will be plenty of new snow to move; a 48 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

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. See the note below for where to find an avalanche forecast.

Wed 18 NovWind-drifted snow expected on north-west through north to north-east-facing slopes.

Snow lying above about 600 m. 10 to 20 cm of new snow over the three days to Wednesday. Frozen early, softening through the day.

Fresh snow

10 to 20 cm of new snow is forecast over the three days to Wednesday. It will be deeper where the wind piles it into drifts.

Where the wind will put the snow

Expect strong southerly winds, around 34 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

Cornices

Cornices are likely to grow above north-west and north-facing slopes because there will be plenty of new snow to move; a 34 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 a frozen crust early, softening through the day into heavier, wetter snow. Conditions will change through the day: thawing 06:00-19:00, refreezing by evening.

Frozen turf

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

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. See the note below for where to find an avalanche forecast.

Snow on the hills

Expect snow lying above about 900 m.

Fresh snow

A few centimetres 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-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 morning: 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-east-facing gullies.

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 11:00 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: 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.

Sunday 15 November 2026 · The Arrochar Alps, Crianlarich and Argyll hills

Confidence: Medium Why?

Uncertainty over rain amounts and timing. Uncertainty over sky cloud cover and sunshine.

What matters most

A mixed day in Argyll and Loch Lomond, with snow on the tops and burns likely to be in spate.

Later0 h sunshine

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 0-15 mph. Gusts around 10-20 mph are possible on exposed ground. Cloud may restrict summit views early on. Rain is forecast in parts of the area during the morning, but its extent and local amounts are uncertain.

Afternoon · 12:00–17:00MixedSummit winds around 5-20 mph. Gusts around 20-30 mph are possible on exposed ground. Rain is forecast on some hills during this period. Cloud may restrict summit views around midday and later. Rain is possible during the afternoon, but forecast models disagree on whether it will fall.

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 a northerly wind of 10–20 mph, gusting 15–25 mph, picking up through the day.

Walking impact

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

Ground conditions

The ground is likely to be wet after recent rain.

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.

Rain and showers

Snow is possible on the tops. Rain arrives mid-afternoon. Expect up to 2 mm in total, measured as melted water, so any snow would lie deeper. Rain is forecast in parts of the area during the morning, but its extent and local amounts are uncertain. Rain is possible during the afternoon, but forecast models disagree on whether it will fall. On some hills, snow is possible on the tops. Snow is forecast on some higher tops in the afternoon. The air freezing level is roughly 600 to 700 m above sea level. Snow can fall below this, but its lower limit is uncertain. Blowing snow may quickly cover paths and footprints and make navigation difficult. 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.

Cloud-free summits

Clear-summit estimate: about 25% early, about 10% around midday and about 15% later.

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 mid-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.

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. Pack waterproofs too, and keep a warm layer dry in your pack.

Freezing level

The freezing level falls through the day, to around 700–1000 m by midday.

Daylight

Full regional overnight outlook

Across these hills, a poor night to camp on open ground. 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 north. It should stay dry. A frost at every height we checked (300-900 m), down to about -5°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 very poor (0/100). 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 psammite, pelite or semipelite, volcanic rock 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.
