The day on the hill
A fine day on Beinn Mhic Cedidh: dry, with light winds and clear tops for most of the day.
Wind
On the summit expect a south-easterly wind of around 0–10 mph first thing, rising to 15–25 mph by mid-afternoon, with gusts of 20–30 mph at the windiest. Lower down on the open hillside the wind will be light, under 10 mph. It gets windier still after dark, with summit gusts of 20–30 mph, so bear that in mind if you will be out late.
Cloud and visibility
The tops are likely to stay mostly clear of cloud, though brief patches cannot be ruled out. 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 -4 to 0°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 4:30pm, so allow time to get off the hill before dark, and carry a head torch.
Sunshine context Model-grid estimate, not summit sunshine
The surrounding model grid indicates 5.3 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 Thursday 5 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 25 mph. It should stay dry. Overnight lows of about 4°C at 300 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.
Clear spells may allow a view of the Moon. Illumination describes the sunlit part of the Moon, not brightness at your pitch.
Overnight window: 5 Nov, 17:00 GMT to 6 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.
Good 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 psammite, a hard, sandy rock that has been squeezed and heated. It grips well when dry and is fair when wet. It is generally solid and blocky. 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 Beinn Mhic Cedidh: dry and breezy, with clear tops for most of the day.
Wind
On the summit expect a south-easterly wind of 10–25 mph for most of the day, with gusts of 25–35 mph at the windiest. Lower down on the open hillside the wind will be light, under 5 mph. A wind like that will be noticeable on ridges and open tops, and you will chill quickly when you stop.
Cloud and visibility
The tops should stay mostly clear of cloud. A few forecast models bring the cloud base down to around 500–800 m at times. The cloud base sits close to summit height, so the top could go in and out of cloud at short notice. Mist or fog is possible in the valleys early on, clearing by about 10am. It will look largely cloudy overhead, but that cloud should mostly stay above the tops.
Rain and ground
Mostly dry, but some forecast models bring rain in the afternoon.
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 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 4:20pm, 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. It's still five days off and could change, so check again nearer the time.
Sunshine context Model-grid estimate, not summit sunshine
The surrounding model grid indicates 6.8 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 Tuesday 10 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 15 mph. It should stay dry. Overnight lows of about 4°C at 600 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.
Fair conditions for exposed scrambling. It should stay mostly dry, but a passing shower could leave the rock damp and slippery. Gusts of 25–35 mph could throw you off balance on exposed moves and ridges. The rock around the summit is mostly psammite, a hard, sandy rock that has been squeezed and heated. It grips well when dry and is fair when wet. It is generally solid and blocky. These are general notes for each rock type, taken from geological maps around the summit, so the rock on your line may differ.

Psammite banded with schist is a hard, sandy rock with flakier, mica-rich layers. It grips well on the harder bands when dry and is slippery on the mica-rich layers when wet. The flaky layers split easily, so some flakes and ledges are loose.

PeliteLochailort Pelite Formation
Schist is a flaky, mica-rich rock that splits into layers. It has only fair grip when dry and is slippery when wet, as the mica gives it a greasy sheen. It splits easily along its layers, so flakes and ledges can be loose, and it is often grassy and vegetated.

A fine day on Beinn Mhic Cedidh: dry and breezy, with clear tops for most of the day.
Wind
On the summit expect a northerly wind of around 5–15 mph first thing, rising to 15–25 mph by early afternoon, with gusts of 20–30 mph at the windiest. Lower down on the open hillside the wind will be light, under 10 mph. A wind like that will be noticeable on ridges and open tops, and you will chill quickly when you stop.
Cloud and visibility
The tops are likely to stay mostly clear of cloud, though brief patches cannot be ruled out. The air should be clear, so expect far-reaching views as long as the tops stay clear.
Rain and ground
It should stay dry.

Night beginning Wednesday 11 November 2026
Full overnight outlook
A poor night to camp on open ground. Gusts reach about 30 mph on open ground, so peg out well and use the guylines. Look for shelter from the northeast. It should stay dry. A frost at every height we checked (300-600 m), down to about 0°C. A warm 3-season or 3–4 season bag rated to about -4°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 -4°C.

Good 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.
