The day on the hill

A fine day on Driesh: 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 northerly, with gusts of 0–10 mph at the windiest.

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 -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 4:10pm, 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 2.5 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 damp air. Light winds on open ground, gusting no more than about 20 mph. The wind swings from northerly to northwesterly overnight, so a pitch sheltered at dusk may not be by morning. It should stay dry. The air is damp around 600 m, so expect heavy condensation. Leave the vents open. A frost up around 900 m, down to about -1°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.

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 psammite banded with schist, 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. On the usual routes up you may also cross diorite, 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 Driesh: dry and breezy, with clear tops for most of the day.

Wind

On the summit expect a north-westerly wind of around 5–15 mph first thing, rising to 20–30 mph by mid-afternoon, 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 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.

Too windy for an exposed pitch above about 600 m. Lower down, a poor night to camp on open ground. Gusts reach about 55 mph around 900 m and nearer 40 mph around 300 m, strong enough to flatten or tear a 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.

Poor conditions for exposed scrambling. The rock should be mostly dry, though drainage lines and shaded holds may still be damp. Snow is likely on the rock and ledges, so it becomes a winter route. Gusts of 25–35 mph could throw you off balance on exposed moves and ridges. The rock around the summit is mostly psammite banded with schist, 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.

The day on the hill

A poor day on the tops of Driesh, with strong, gusty winds and a bitter wind chill.

Wind

On the summit expect a northerly wind of 25–40 mph for most of the day, with gusts of 40–50 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.

The tops are likely to stay mostly clear of cloud, though brief patches cannot be ruled out.

Rain and ground

It should stay dry.

On the tops it will be around -4 to 0°C, feeling like -14 to -10°C in the wind. The freezing level is around 400–700 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.

The day on the hill

A mixed day on Driesh, with a bitter wind chill and a blustery wind.

Wind

On the summit expect a north-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 the wind will be light, under 10 mph. Gusts like that are strong enough to make walking into it hard work, with buffeting on ridges and edges.

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 -12 to -8°C in the wind. The freezing level is around 400–700 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

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

Full overnight outlook

Too windy for an exposed pitch above about 600 m. Lower down, a poor night to camp on open ground. Gusts reach about 50 mph around 900 m and nearer 35 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. Dry to pitch, then a little rain overnight, easing by morning, though the tent may still be 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. 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.

Generic exposed-rock guidance

Full climbing & scrambling outlook

Mixed conditions for exposed scrambling. The rock should be mostly dry, though drainage lines and shaded holds may still be damp. Gusts of 30–40 mph could throw you off balance on exposed moves and ridges. The rock around the summit is mostly psammite banded with schist, 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. On the usual routes up you may also cross diorite, 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 poor day on the tops of Driesh, with sleet or snow on the tops and a blustery wind.

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 1100 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 600–900 m around midday. 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.

Rain and ground

Sleet at first, 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.

Sunshine context Model-grid estimate, not summit sunshine

The surrounding model grid indicates 2.2 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.

Not a night to camp on the open hill. Gusts reach about 55 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 8 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.

The day on the hill

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

Wind

On the summit expect a south-westerly wind of 25–35 mph for most of the day, with gusts of 40–50 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 65–75 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. The cloud base lowers through the day. The cloud base could be as low as 800–1100 m by late afternoon. A few forecast models bring it lower still, to around 300–600 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.

Rain and ground

Drizzle for much of the day. 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.

The wind swings from southwesterly to northwesterly overnight, so a pitch sheltered at dusk may not be by morning. Expect a wet night, around 9 mm of rain, mostly early on, so you'll likely pitch in the rain. 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 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.

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. Gusts of 40–50 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 banded with schist, 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. On the usual routes up you may also cross diorite, 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.

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. 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

Dry, with light winds on Driesh. 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.

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 -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 4pm, 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

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 west. 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. A frost at every height we checked (300-900 m), down to about -4°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.

Generic exposed-rock guidance

Full climbing & scrambling outlook

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. Gusts of 20–30 mph will be noticeable on exposed ridges. The rock around the summit is mostly psammite banded with schist, 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.
