The day on the hill
A good day on Sail: dry and breezy, with clear tops for most of the day.
Wind
On the summit expect an easterly wind of around 10–20 mph first thing, rising to 20–30 mph by midday, with gusts of 30–40 mph at the windiest. Lower down on the open hillside it will be more like 5–15 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 drift in and out of cloud, with the best chance of a clear summit early in the morning. The cloud base sits close to summit height, so the top could go in and out of cloud at short notice. 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 2 to 6°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
Sunset is around 4:30pm, 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 4.6 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 poor night to camp on open ground. Gusts reach about 35 mph on open ground, so peg out well and use the guylines. Look for shelter from the east. It should stay dry. The air is damp at every height we checked (300-600 m), so expect heavy condensation. Leave the vents open. 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.
Extensive cloud may limit moonlight. 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.

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. Gusts of 30–40 mph could throw you off balance on exposed moves and ridges. The rock around the summit is mostly mudstone or slate, a soft, fine-grained rock that splits into thin flakes. It has only fair grip even when dry and is slippery when wet. It is often shattered, breaking into loose flakes, scree and poor holds. 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 Sail: dry, with light winds.
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 start clear, but the cloud comes down onto them around midday. The cloud base could be as low as 500–800 m mid-afternoon. Mist or fog is possible in the valleys early on, clearing by about 10am. The tops should be above it in clearer air. It looks hazy, so views may be limited even when the tops are 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 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 4:25pm, 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. It's still four days off and could change, so check again nearer the time.

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. 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 mudstone or slate, a soft, fine-grained rock that splits into thin flakes. It has only fair grip even when dry and is slippery when wet. It is often shattered, breaking into loose flakes, scree and poor holds. 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
Dry and breezy on Sail. Cloud could cover the tops and limit the views.
Wind
On the summit expect a south-easterly 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 it will be more like 5–15 mph. Gusts like that will be noticeable on ridges and open tops, and you will chill quickly when you stop.
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 could be as low as 400–700 m around midday. Mist or fog is possible in the valleys early on, clearing by about 1am.
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 -2 to 2°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.

Full overnight outlook
A mixed night to camp, mainly because of the rain. Gusts reach about 30 mph on open ground, so peg out well and use the guylines. Look for shelter from the southeast. Expect about 7 mm of rain, with rain while you pitch and still falling when you pack up. Overnight lows of about 6°C at 300 m. A 3-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 3-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.
Fair conditions for exposed scrambling. The rock should be drying, but damp patches, shaded holds and drainage lines may still be wet. Gusts of 25–35 mph could throw you off balance on exposed moves and ridges. The rock around the summit is mostly mudstone or slate, a soft, fine-grained rock that splits into thin flakes. It has only fair grip even when dry and is slippery when wet. It is often shattered, breaking into loose flakes, scree and poor holds.

This is about Sail on Tuesday 10 November 2026. It asks about intentions, not whether you actually went out. No name or account is needed.
A mixed day on Sail, with rain for much of the day and cloud coming and going on the summit.
Things to watch
Burns could rise quickly through the day and overnight. Timings are rough. Turn back if a crossing looks unsafe.
Wind
On the summit expect light winds of up to 15 mph, mainly easterly, with gusts of 15–25 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 drift in and out of cloud, with the best chance of a clear summit around midday. The cloud base could be as low as 600–900 m early in the morning. 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.
Rain and ground
Rain for much of the day, becoming heavier later. Expect 5–10 mm in total.
Warmth and kit
On the tops it will be around 4 to 8°C, feeling like 0 to 4°C in the wind. The freezing level is above the summits. Take a warm layer and a hat for the top. Pack waterproofs too, and keep a warm layer dry in your pack.
Daylight
A short day, with only about 9 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
It's still seven days off and could change, so check again nearer the time.

Night beginning Wednesday 11 November 2026
Full overnight outlook
A poor night to camp on open ground. Gusts reach about 35 mph on open ground, which makes for a noisy, testing night even in a good tent. Look for shelter from the northeast. Expect a wet night, around 10 mm of rain, mostly early on, so you'll likely pitch in the rain. A frost at every height we checked (300-600 m), down to about -1°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.
