The day on the hill
A fine day on Ben Wyvis: dry, with light winds and clear tops for most of the day.
Wind
On the summit expect light winds of up to 10 mph, mainly south-easterly, with gusts of 10–20 mph at the windiest.
Cloud and visibility
The tops are likely to drift in and out of cloud, with the best chance of a clear summit around midday. The cloud base could be as low as 700–1000 m around midday. Patchy mist is possible in sheltered valleys early on. Good spells of sunshine are likely. The air should be clear, so expect far-reaching views as long as the tops stay clear.
Rain and ground
It should stay dry.
Warmth and kit
On the tops it will be around 0 to 4°C, feeling like -2 to 2°C in the wind. The freezing level is above the summits. Take a hat, gloves, a windproof and a spare warm layer.
Daylight
A short day, with only about 9 hours of daylight. Sunset is around 4:25pm, so allow time to get off the hill before dark, and carry a head torch.
Forecast confidence
Cloud height is hard to pin down, so the summit could be in or out of cloud at short notice. Things could still change through the day, so keep an eye on the sky.
Sunshine context Model-grid estimate, not summit sunshine
The surrounding model grid indicates 6.2 h of sunshine. This is not a forecast of time in sunshine on the summit. Use the cloud and views outlook above for the conditions on this mountain.

Night beginning Wednesday 4 November 2026
Full overnight outlook
A mixed night to camp, mainly because of damp air. Light winds on open ground, gusting no more than about 25 mph. It should stay dry. Up around 900 m you'd likely be in cloud for part of the night: damp, and hard to find your way if you need to move. The air is damp at every height we checked (300-900 m), so expect heavy condensation. Leave the vents open. A cold night, down to about 2°C around 900 m. A warm 3-season or 3–4 season bag rated to about 0°C comfort, and a warm mat, should do. Allow more if you sleep cold.
Views of the Moon may come and go through cloud breaks. Illumination describes the sunlit part of the Moon, not brightness at your pitch.
Overnight window: 4 Nov, 17:00 GMT to 5 Nov, 08:00 GMT. Approximate open-horizon times; hills can hide the Moon. Still take a headtorch.

Warmth planning: As a broad starting point, consider a warm 3-season or 3–4 season bag with an ISO/EN comfort rating at or below about 0°C. Allow more margin if you sleep cold or expect fatigue, and use an adequate insulated mat. Dampness is possible, so keep the sleep system dry and ensure its insulation remains effective if damp.
Excellent conditions for exposed scrambling. The rock should be mostly dry, though drainage lines and shaded holds may still be damp. Cloud on the tops may make route-finding and retreat harder. The rock around the summit is mostly gneiss, a very old, hard, banded rock. It grips very well when dry and stays reasonably grippy when wet. It is usually very solid. On the usual routes up you may also cross psammite, which grips well when dry and is fair when wet. These are general notes for each rock type, taken from geological maps around the summit, so the rock on your line may differ.

The day on the hill
A mixed day on Ben Wyvis, with cloud coming and going on the summit.
Wind
On the summit expect a south-easterly wind of 10–20 mph for most of the day, with gusts of 15–25 mph at the windiest.
Cloud and visibility
Expect the summit to be in cloud for most of the day. The cloud base could be as low as 600–900 m mid-afternoon. 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. Mist or fog is possible in the valleys early on, clearing by about 11am.
Rain and ground
It should stay dry.
Warmth and kit
On the tops it will be around 0 to 4°C, feeling like -6 to -2°C in the wind. The freezing level is above the summits. Take a hat, gloves, a windproof and a spare warm layer.
Daylight
A short day, with only about 9 hours of daylight. Sunset is around 4:25pm, so allow time to get off the hill before dark, and carry a head torch.
Forecast confidence
Cloud heights are particularly hard to pin down today. Some of the detail could still change, so have a last look at the forecast in the morning before you set off.

The day on the hill
A fine day on Ben Wyvis: dry, with light winds and clear tops for most of the day.
Wind
On the summit expect light winds of up to 10 mph, mainly westerly, with gusts of 5–15 mph at the windiest.
Cloud and visibility
The tops are likely to stay mostly clear of cloud, though brief patches cannot be ruled out.
Rain and ground
It should stay dry.
Warmth and kit
On the tops it will be around -4 to 0°C, feeling like -6 to -2°C in the wind. The freezing level is close to summit height. Take a hat, gloves, a windproof and a spare warm layer.
Daylight
A short day, with only about 8 hours of daylight. Sunset is around 4:15pm, so allow time to get off the hill before dark, and carry a head torch.
Forecast confidence
Cloud height is hard to pin down, so the summit could be in or out of cloud at short notice. It's still four days off and could change, so check again nearer the time.
Sunshine context Model-grid estimate, not summit sunshine
The surrounding model grid indicates 4.2 h of sunshine. This is not a forecast of time in sunshine on the summit. Use the cloud and views outlook above for the conditions on this mountain.

Night beginning Sunday 8 November 2026
Full overnight outlook
A mixed night to camp, mainly because of the cold. Light winds on open ground, gusting no more than about 10 mph. It should stay dry. A cold night, down to about 2°C around 900 m. A warm 3-season or 3–4 season bag rated to about 0°C comfort, and a warm mat, should do. Allow more if you sleep cold.
Warmth planning: As a broad starting point, consider a warm 3-season or 3–4 season bag with an ISO/EN comfort rating at or below about 0°C. Allow more margin if you sleep cold or expect fatigue, and use an adequate insulated mat. Dampness is possible, so keep the sleep system dry and ensure its insulation remains effective if damp.
Good conditions for exposed scrambling. The rock should be mostly dry, though drainage lines and shaded holds may still be damp. The rock around the summit is mostly gneiss, a very old, hard, banded rock. It grips very well when dry and stays reasonably grippy when wet. It is usually very solid. On the usual routes up you may also cross psammite, which grips well when dry and is fair when wet. These are general notes for each rock type, taken from geological maps around the summit, so the rock on your line may differ.

The day on the hill
A good day on Ben Wyvis: dry, with light winds.
Wind
On the summit expect a south-westerly wind of 10–20 mph for most of the day, with gusts of 15–25 mph at the windiest. The wind turns southerly around midday. Lower down on the open hillside the wind will be light, under 10 mph.
Cloud and visibility
Cloud on the tops early should lift off them by midday. The cloud base could be as low as 500–800 m early in the morning. The air should be clear, so expect far-reaching views whenever the tops come out of the cloud.
Rain and ground
It should stay dry.
Warmth and kit
On the tops it will be around -4 to 0°C, feeling like -10 to -6°C in the wind. The freezing level is around 800–1100 m, so it will be below freezing on the tops. Take a hat, gloves, a windproof and a spare warm layer.

The day on the hill
A good day on Ben Wyvis: dry, with light winds.
Wind
On the summit expect a northerly wind of 5–20 mph for most of the day, with gusts of 20–30 mph at the windiest. Lower down on the open hillside it will be more like 5–15 mph. It gets windier still after dark, with summit gusts of 25–35 mph, so bear that in mind if you will be out late.
Cloud and visibility
The tops are likely to drift in and out of cloud, with the best chance of a clear summit early in the morning. The cloud base could be as low as 700–1000 m around midday.
Rain and ground
It should stay dry.
Warmth and kit
On the tops it will be around -4 to 0°C, feeling like -10 to -6°C in the wind. The freezing level falls through the day, to around 900–1200 m by early afternoon. Take a hat, gloves, a windproof and a spare warm layer.

Full overnight outlook
A poor night to camp on open ground. Gusts reach about 35 mph around 900 m and nearer 25 mph around 300 m, so peg out well and use the guylines. Look for shelter from the north. It should stay dry. A frost at every height we checked (300-900 m), down to about -3°C. A 4-season bag rated to about -6°C comfort, and a warm mat, should do. Allow more if you sleep cold.
Warmth planning: As a broad starting point, consider a 4-season bag with an ISO/EN comfort rating at or below about -6°C.

Fair conditions for exposed scrambling. The rock should be mostly dry, though drainage lines and shaded holds may still be damp. Gusts of 20–30 mph will be noticeable on exposed ridges. The rock around the summit is mostly gneiss, a very old, hard, banded rock. It grips very well when dry and stays reasonably grippy when wet. It is usually very solid.
