The day on the hill

A fine day on A' Bhuidheanach Bheag: 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 north-easterly, with gusts of 5–15 mph at the windiest. Lower down on the open hillside the wind will be light, under 5 mph.

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 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.

Sunshine context Model-grid estimate, not summit sunshine

Night beginning Tuesday 10 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 15 mph. The wind swings from northerly to northwesterly overnight, so a pitch sheltered at dusk may not be by morning. It should stay dry. 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. The air is damp at every height we checked (300-900 m), so expect heavy condensation. Leave the vents open. A frost up around 900 m, down to about -2°C. A warm 3-season or 3–4 season bag rated to about -2°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 -2°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.

Open-hillside reference. A sheltered pitch may be calmer; cols and ridges may be much windier. Tent design and the exact pitch still matter. Read about sleeping-bag comfort ratings, pitching in strong winds or using the wild-camping forecast.

Full climbing & scrambling outlook

Excellent 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 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 fine day on A' Bhuidheanach Bheag: dry, with light winds and clear tops for most of the day.

Wind

On the summit expect a north-westerly 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 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 -4 to 0°C, feeling like -10 to -6°C in the wind. The freezing level is around 600–900 m, so it will be below freezing on the tops. Take a hat, gloves, a windproof and a spare warm layer.

Gusts reach about 45 mph around 900 m and nearer 30 mph around 300 m, which makes for a noisy, testing night even in a good tent. Pitch low down and in real shelter, or leave it for another night. Expect a little rain, mostly early on, so you'll likely pitch in the rain. A frost at every height we checked (300-900 m), down to about -4°C. A 4-season bag rated to about -6°C comfort, and a warm mat, should do. Allow more if you sleep cold.

The day on the hill

A mixed day on A' Bhuidheanach Bheag, with snow on the tops.

Snow and navigation

Snow is forecast on the tops in the afternoon. The air freezing level is roughly 800 to 1000 m above sea level. Snow can fall below this, but its lower limit is uncertain. The forecast model suggests less than 1 cm of fresh snowfall at around 1000 m between 08:00 and 17:00 (local time). The amount settling is uncertain and will vary with melting and drifting. 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.

Wind

On the summit expect a north-westerly wind of 15–30 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 10 mph. Gusts 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 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 800–1100 m mid-afternoon. A few forecast models bring it lower still, to around 500–800 m. Good spells of sunshine are likely.

Rain and ground

Snow arrives mid-afternoon.

Warmth and kit

On the tops it will be around -4 to 0°C, feeling like -12 to -8°C in the wind. The freezing level is around 500–800 m, so it will be below freezing on the tops. Take a hat, gloves, a windproof and a spare warm layer. Pack waterproofs too, and keep a warm layer dry in your pack.

Daylight

A short day, with only about 8 hours of daylight. Sunset is around 4:10pm, so allow time to get off the hill before dark, and carry a head torch.

Forecast confidence

The forecast models disagree on how strong the wind will be, so it could be noticeably stronger than this. It's still three days off and could change, so check again nearer the time.

Full overnight outlook

Too windy for an exposed pitch up around 900 m. Lower down, a mixed night to camp, mainly because of the wind. Gusts reach about 45 mph around 900 m and nearer 30 mph around 300 m, enough to damage a tent on open ground. Pitch low down and in real shelter, or leave it for another night. Expect some light rain, with rain while you pitch and still falling when you pack up. 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. A cold night, down to about 1°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.

Generic exposed-rock guidance

Full climbing & scrambling outlook

Very poor conditions for exposed scrambling. The rock is likely to be wet and slippery through the day. Icy patches are likely on the rock, which makes it treacherous without winter kit. Gusts of 25–35 mph could throw you off balance on exposed moves and ridges. Cloud on the tops may make route-finding and retreat harder. 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 poor day on the tops of A' Bhuidheanach Bheag, with sleet or snow on the tops and the summit in cloud for most of the day.

Snow and navigation

Sleet or snow is possible on the tops during the morning and afternoon, with small temperature changes affecting the mix. The air freezing level is roughly 1000 to 1200 m above sea level. Snow can fall below this, but its lower limit is uncertain.

Wind

On the summit expect a south-westerly wind of 20–30 mph for most of the day, with gusts of 30–40 mph at the windiest. Lower down on the open hillside it will be more like 10–20 mph. Gusts like that are strong enough to make walking into it hard work, with buffeting on ridges and edges.

Cloud and visibility

Expect the summit to be in cloud for most of the day. The cloud base could be as low as 500–800 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. Any sunshine is more likely on lower ground than on the summit.

Rain and ground

Sleet for much of the day. Expect 2–5 mm in total, measured as melted water, so any snow would lie deeper. Some forecast models keep it drier in the afternoon.

Warmth and kit

On the tops it will be around -2 to 2°C, feeling like -10 to -6°C in the wind. The freezing level is close to summit height. Take a hat, gloves, a windproof and a spare warm layer. Pack waterproofs too, and keep a warm layer dry in your pack.

Daylight

A short day, with only about 8 hours of daylight. Sunset is around 4:05pm, so allow time to get off the hill before dark, and carry a head torch.

Forecast confidence

There is some disagreement between forecast models on wind strength. 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 4.3 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.

Cloud may obscure this summit even while the surrounding model grid indicates sunshine. The low cloud-free summit estimate is a reason to be cautious about expecting views.

Not a night to camp on the open hill. Gusts reach about 60 mph around 900 m and nearer 40 mph around 300 m, strong enough to flatten or tear a tent. Don't count on finding shelter once you're up there. Choose another night or a low, sheltered spot. Expect a wet night, around 10 mm of rain, with rain while you pitch and still falling when you pack up. 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. 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.

The day on the hill

A poor day on the tops of A' Bhuidheanach Bheag, with drizzle for much of the day and a blustery wind.

Wind

On the summit expect a south-westerly wind of 20–35 mph for most of the day, with gusts of 35–45 mph at the windiest. Lower down on the open hillside it will be more like 10–20 mph. Gusts like that are strong enough to make walking into it hard work, with buffeting on ridges and edges. If the windier forecast models are right, summit gusts could reach 65–75 mph.

Cloud and visibility

The tops are likely to drift in and out of cloud, with the best chance of a clear summit around midday. A few forecast models bring the cloud base down to around 300–600 m at times. The cloud base sits close to summit height, so the top could go in and out of cloud at short notice. 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. Visibility may drop briefly in showers. It looks hazy, so views may be limited even when the tops are clear.

Rain and ground

Drizzle for much of the day, becoming heavier later. Expect 2–5 mm in total. Some forecast models keep it drier 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 above the summits. Take a hat, gloves, a windproof and a spare warm layer. Pack waterproofs too, and keep a warm layer dry in your pack.

A short day, with only about 8 hours of daylight. Sunset is around 4:05pm, so allow time to get off the hill before dark, and carry a head torch.

A few forecast models bring the cloud base down to around 600–900 m at times. The cloud base sits close to summit height, so the top could go in and out of cloud at short notice. Patchy mist is possible in sheltered valleys early on.

Rain and ground

It should stay dry. Some forecast models bring rain, so don't count on it staying dry. It will be wet underfoot after recent rain.

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 500–800 m, so it will be below freezing on the tops. 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 4:05pm, so allow time to get off the hill before dark, and carry a head torch.

Forecast confidence

It's still six days off and could change, so check again nearer the time.

Full overnight outlook

Too windy for an exposed pitch up around 900 m. Lower down, a poor night to camp on open ground. Gusts reach about 45 mph around 900 m and nearer 30 mph around 300 m, which makes for a noisy, testing night even in a good tent. Pitch low down and in real shelter, or leave it for another night. The wind swings from westerly to easterly overnight, so a pitch sheltered at dusk may not be by morning. Dry to pitch, then some light rain by morning, so you'll likely pack up in the wet. 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. A frost at every height we checked (300-900 m), down to about -3°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. 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.

Open-hillside reference. A sheltered pitch may be calmer; cols and ridges may be much windier. Tent design and the exact pitch still matter. Read about sleeping-bag comfort ratings, pitching in strong winds or using the wild-camping forecast.

Full climbing & scrambling outlook

Very poor conditions for exposed scrambling. After recent rain the rock may still be wet in places, especially shaded holds and drainage lines. Icy patches are likely on the rock, which makes it treacherous without winter kit. 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 is 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, from geological map samples at and around the summit. The rock on your line can differ, and lichen, vegetation and seepage all change how it feels underfoot.

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.
