The day on the hill

A fine day on Schiehallion: 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 -6 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.

Daylight

A short day, with only about 9 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 northeasterly to northwesterly overnight, so a pitch sheltered at dusk may not be by morning. 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 up around 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.

Generic exposed-rock guidance

Full climbing & scrambling outlook

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 quartzite, a very hard rock made almost entirely of quartz. It grips well when dry and is notoriously slippery when wet. It splits into sharp, angular blocks, so expect loose scree and boulder fields, and edges that can cut gloves and hands. On the usual routes up you may also cross gneiss, which grips very well when dry and stays reasonably grippy 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.

Quartzite is a very hard rock made almost entirely of quartz. It grips well when dry and is notoriously slippery when wet. It splits into sharp, angular blocks, so expect loose scree and boulder fields, and edges that can cut gloves and hands. 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.

The day on the hill

A fine day on Schiehallion: dry and breezy, with clear tops for most of the day.

Wind

On the summit expect a north-westerly wind of 5–25 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 10 mph. Gusts like that will be noticeable on ridges and open tops, and you will chill quickly when you stop. It gets windier still after dark, with summit gusts of 30–40 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 -6 to -2°C, feeling like -12 to -8°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.

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

There is some disagreement between forecast models on wind strength. 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 mixed day on Schiehallion, with a bitter wind chill and a blustery wind.

Wind

On the summit expect a northerly wind of 25–35 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 5–15 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 45–55 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 -6 to -2°C, feeling like -14 to -10°C in the wind. The freezing level is around 500–800 m, so it will be below freezing on the tops. Hat, gloves and a warm insulated layer are essential, with extra warmth for stops.

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

There is some disagreement between forecast models on wind strength. It's still two days off and could change, so check again nearer the time.

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 -12 to -8°C in the wind. The freezing level is around 600–900 m, so it will be below freezing on the tops. Hat, gloves and a warm insulated layer are essential, with extra warmth for stops.

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

There is some disagreement between forecast models on wind strength. Cloud heights are particularly hard to pin down today. It's still three days off and could change, so check again nearer the time.

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. 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 up around 900 m, so expect heavy condensation. Leave the vents open. A cold night, down to about 0°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.

Full climbing & scrambling outlook

Poor conditions for exposed scrambling. The rock should be mostly dry, though drainage lines and shaded holds may still be damp. Gusts of 35–45 mph could throw you off balance on exposed moves and ridges. The rock around the summit is mostly quartzite, a very hard rock made almost entirely of quartz. It grips well when dry and is notoriously slippery when wet. It splits into sharp, angular blocks, so expect loose scree and boulder fields, and edges that can cut gloves and hands. On the usual routes up you may also cross gneiss, which grips very well when dry and stays reasonably grippy 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 poor day on the tops of Schiehallion, with sleet or snow on the tops and a blustery wind.

Snow and navigation

Sleet or snow is possible on the tops in the morning, with small temperature changes affecting the mix. The air freezing level is roughly 1100 to 1200 m above sea level. Snow can fall below this, but its lower limit is uncertain.

Wind

On the summit expect a westerly wind of 25–35 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 5–15 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 800–1100 m mid-afternoon. A few forecast models bring it lower still, to around 500–800 m. 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

A band of sleet crosses mid-morning, clearing by midday. Expect up to 2 mm in total, measured as melted water, so any snow would lie deeper.

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

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

The day on the hill

A poor day on the tops of Schiehallion, with strong, gusty winds and drizzle for much of the day.

Wind

On the summit expect a south-westerly wind of 25–40 mph for most of the day, with gusts of 45–55 mph at the windiest. Lower down on the open hillside it will be more like 5–15 mph. Gusts like that are strong enough to knock you off balance, so take care near edges and on narrow ridges. If the windier forecast models are right, summit gusts could reach 70–80 mph. It gets windier still after dark, with summit gusts of 45–55 mph, so bear that in mind if you will be out late.

Cloud and visibility

Clear spells are possible, but cloud could cover the tops for part of the day. Forecast models differ on how much summit cloud develops. The cloud base lifts through the day. A few forecast models bring the cloud base down to around 800–1100 m at times. The cloud base sits close to summit height, so the top could go in and out of cloud at short notice.

Rain and ground

Drizzle for much of the day. Expect 2–5 mm in total. Some forecast models keep it drier later on.

Warmth and kit

On the tops it will be around 0 to 4°C, feeling like -8 to -4°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.

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.

The day on the hill

Dry, with light winds on Schiehallion, with a bitter wind chill. Cloud could cover the tops and limit the views.

Wind

On the summit expect a westerly wind of 10–20 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.

Cloud and visibility

Clear spells are possible, but cloud could cover the tops for part of the day. Forecast models differ on how much summit cloud develops. A few forecast models bring the cloud base down to around 600–900 m at times. 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.

Warmth and kit

On the tops it will be around -6 to -2°C, feeling like -12 to -8°C in the wind. The freezing level is around 600–900 m, so it will be below freezing on the tops. Hat, gloves and a warm insulated layer are essential, with extra warmth for stops.

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.

Night beginning Monday 16 November 2026

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 40 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 about 3 mm of rain overnight and into the morning, so expect to pack a wet tent. 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.

Generic exposed-rock guidance

Full climbing & scrambling outlook

Poor conditions for exposed scrambling. The rock should be drying, but damp patches, shaded holds and drainage lines may still be wet. Icy patches are likely on the rock, which makes it treacherous without winter kit. Gusts of 20–30 mph will be noticeable on exposed ridges. The rock around the summit is mostly quartzite, a very hard rock made almost entirely of quartz. It grips well when dry and is notoriously slippery when wet. It splits into sharp, angular blocks, so expect loose scree and boulder fields, and edges that can cut gloves and hands. On the usual routes up you may also cross gneiss, which grips very well when dry and stays reasonably grippy 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.

Quartzite is a very hard rock made almost entirely of quartz. It grips well when dry and is notoriously slippery when wet. It splits into sharp, angular blocks, so expect loose scree and boulder fields, and edges that can cut gloves and hands. 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.

Quartzite is a very hard rock made almost entirely of quartz. It grips well when dry and is notoriously slippery when wet. It splits into sharp, angular blocks, so expect loose scree and boulder fields, and edges that can cut gloves and hands.

BGS record
Route sample Amphibolite Scottish Highland Ordovician Minor Intrusion Suite Around 1,075 m Seen on Schiehallion

Gneiss is a very old, hard, banded rock. It grips very well when dry and stays reasonably grippy when wet. It is usually very solid.

BGS record
Route sample Metalimestone and pelite Blair Atholl Dark Limestone And Dark Schist Formation Around 426 m Seen on Schiehallion

Limestone is a pale sedimentary rock. It grips well where it is rough, but polished limestone is glassy and is very slippery when wet. It is generally solid, though cracked and fissured along its edges.
