The day on the hill

A poor day on the tops of Pen-y-ghent, with rain arriving in the early afternoon and a blustery wind.

Wind

On the summit expect a south-westerly wind rising from around 20–30 mph to 30–40 mph mid-afternoon, then easing to 15–25 mph, with gusts of 40–50 mph at the windiest. Lower down on the open hillside it will be more like 5–20 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 75–85 mph. It gets windier still later in the day, with summit gusts of 45–55 mph, so bear that in mind if you will be out late.

Cloud and visibility

Expect the summit to be in cloud for most of the day. The cloud base could be as low as 300–600 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. Visibility may drop briefly in showers.

Rain and ground

A band of rain moves in during the early afternoon and becomes heavier through the afternoon. Expect 5–10 mm in total. Some forecast models keep it drier in the afternoon.

Warmth and kit

On the tops it will be around 2 to 6°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.

Daylight

Sunset is around 6pm, so allow time to get off the hill before dark, and carry a head torch.

Forecast confidence

Things could still change through the day, so keep an eye on the sky.

Night beginning Wednesday 21 October 2026

Full overnight outlook

Too windy for an exposed pitch up around 600 m. Lower down, a poor night to camp on open ground. Gusts reach about 40 mph on open ground, 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 about 4 mm of rain, mostly early on, so you'll likely pitch in the rain. 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.

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 sandstone, a gritty sedimentary rock. It is rough and grippy when dry and can feel greasy when damp or covered in lichen. It is usually solid in terraced steps, but softer layers crumble and weathered edges can break away. On the usual routes up you may also cross limestone, which grips well where it is rough, but polished limestone is glassy and is very slippery 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 Pen-y-ghent: dry and breezy, with clear tops for most of the day.

Wind

On the summit expect a westerly wind of 10–25 mph for most of the day, with gusts of 20–30 mph at the windiest. Lower down on the open hillside it will be more like 5–15 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 clear of cloud all day. The air should be clear too, so expect far-reaching views from the tops.

Rain and ground

It should stay dry.

The day on the hill

A poor day on the tops of Pen-y-ghent, with very strong, gusty winds and burns likely to be in spate.

Things to watch

There is a small chance of a thunderstorm from the morning into the afternoon. If you hear thunder, head down off the tops and away from ridges. Storms can bring sudden strong gusts and heavy rain. Storm timing could easily shift by a few hours. Burns and rivers are likely to be in spate during the morning, so unbridged crossings could be difficult or impossible. Timings are rough. Turn back if a crossing looks unsafe.

Wind

On the summit expect a westerly wind of around 10–20 mph first thing, rising to 35–45 mph by mid-afternoon, with gusts of 45–55 mph at the windiest. The wind turns north-westerly in the early afternoon. Lower down on the open hillside it will be more like 5–20 mph. Gusts like that are strong enough to make walking very difficult and tiring, with a risk of being blown off your feet. Avoid exposed 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 mid-afternoon. The cloud base could be as low as 300–600 m mid-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. Expect 5–10 mm in total. Totals are uncertain and could be higher.

Warmth and kit

On the tops it will be around 0 to 4°C, feeling like -8 to -4°C in the wind. It turns colder through the day. 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

Sunset is around 5:55pm, so allow time to get off the hill before dark, and carry a head torch.

Forecast confidence

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

Night beginning Friday 23 October 2026

Full overnight outlook

Not a night to camp on the open hill. Gusts reach about 50 mph on open ground, enough to damage a tent on open ground. Don't count on finding shelter once you're up there. Choose another night or a low, sheltered spot. The wind swings from northwesterly to westerly overnight, so a pitch sheltered at dusk may not be by morning. Expect some light rain, mostly early on, so you'll likely pitch in the rain. A cold night, down to about 2°C around 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.

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 45–55 mph are strong enough to make walking very difficult and tiring, with a risk of being blown off your feet. Avoid exposed ridges and edges. Cloud on the tops may make route-finding and retreat harder. There is a small chance of a thunderstorm from the morning into the afternoon. If you hear thunder, get off exposed rock and ridges. The rock around the summit is mostly sandstone, a gritty sedimentary rock. It is rough and grippy when dry and can feel greasy when damp or covered in lichen. It is usually solid in terraced steps, but softer layers crumble and weathered edges can break away. On the usual routes up you may also cross limestone, which grips well where it is rough, but polished limestone is glassy and is very slippery 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.

Sandstone is a gritty sedimentary rock. It is rough and grippy when dry and can feel greasy when damp or covered in lichen. It is usually solid in terraced steps, but softer layers crumble and weathered edges can break away. These are general notes for each rock type, from geological map samples at and around the summit.

The day on the hill

A poor day on the tops of Pen-y-ghent, with very strong, gusty winds and rain for much of the day.

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 a south-westerly wind of around 20–30 mph first thing, rising to 45–55 mph by mid-afternoon, with gusts of 60–70 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 very difficult and tiring, with a risk of being blown off your feet. Avoid exposed ridges and edges. If the windier forecast models are right, summit gusts could reach 80–90 mph.

Cloud and visibility

The tops are likely to drift in and out of cloud. The cloud base could be as low as 200–500 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.

Rain and ground

Rain for much of the day, becoming heavier through the afternoon. Expect 10–20 mm in total. Totals are uncertain and could be higher. It will be wet underfoot after recent rain.

Warmth and kit

On the tops it will be around 0 to 4°C, feeling like -6 to -2°C in the wind. It turns milder through the day. 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

Sunset is around 5:50pm, 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.

The day on the hill

A poor day on the tops of Pen-y-ghent, with very strong, gusty winds and drizzle clearing by mid-afternoon.

Wind

On the summit expect a westerly wind of 40–50 mph for most of the day, with gusts of 60–70 mph at the windiest. Lower down on the open hillside it will be more like 20–30 mph. Gusts like that are strong enough to make walking very difficult and tiring, with a risk of being blown off your feet. Avoid exposed ridges and edges. If the windier forecast models are right, summit gusts could reach 70–80 mph.

Cloud and visibility

The tops should stay mostly clear of cloud. A few forecast models bring the cloud base down to around 200–500 m at times. The cloud base sits close to summit height, so the top could go in and out of cloud at short notice. Visibility may drop briefly in showers. It will look largely cloudy overhead, but that cloud should mostly stay above the tops.

Rain and ground

Drizzle at first, clearing by mid-afternoon. Expect 2–5 mm in total. Some forecast models keep it drier in the afternoon. It will be wet underfoot after recent rain.

Warmth and kit

On the tops it will be around 2 to 6°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.

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 60–70 mph are strong enough to make walking very difficult and tiring, with a risk of being blown off your feet. Avoid exposed ridges and edges. The rock around the summit is mostly sandstone, a gritty sedimentary rock. It is rough and grippy when dry and can feel greasy when damp or covered in lichen. It is usually solid in terraced steps, but softer layers crumble and weathered edges can break away. On the usual routes up you may also cross limestone, which grips well where it is rough, but polished limestone is glassy and is very slippery 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 Pen-y-ghent, with a blustery wind and drizzle arriving mid-morning.

Wind

On the summit expect a south-westerly wind of around 10–20 mph first thing, rising to 25–35 mph by mid-afternoon, 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 55–65 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 400–700 m mid-afternoon.

Rain and ground

Drizzle sets in mid-morning. Expect 2–5 mm in total. Totals are uncertain and could be higher. The ground is very wet after recent rain, so expect boggy paths.

Warmth and kit

On the tops it will be around 0 to 4°C, feeling like -4 to 0°C in the wind. It turns milder through the day. 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

Sunset is around 4:45pm, 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 five days off and could change, so check again nearer the time.

Night beginning Monday 26 October 2026

Full overnight outlook

Too windy for an exposed pitch up around 600 m. Lower down, a poor night to camp on open ground. Gusts reach about 45 mph on open ground, enough to damage a tent on open ground. Pitch low down and in real shelter, or leave it for another night. Expect a wet night, around 12 mm of rain, with rain while you pitch and still falling when you pack up. Up around 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. Overnight lows of about 9°C at 600 m. A 3-season bag rated to about 6°C comfort, and a warm mat, should do. Allow more if you sleep cold. The ground will be sodden after recent rain, so pick a firm, well-drained pitch.

The day on the hill

A poor day on the tops of Pen-y-ghent, with strong, gusty winds and rain 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 10–20 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 50–60 mph.

Darkness of the surroundings

Estimated darkness rank 921 of 980 assessed peaks (1 is darkest), based on surrounding artificial light in 2021. This is not a measurement of tonight’s sky.

2021 artificial-light baseline, not measured sky brightness or a Bortle class. Changes to lighting, blue-rich LEDs, terrain screening, atmospheric scattering and cloud-reflected light are not resolved. Similar ranks are not meaningfully distinct. Darkness is not a recommendation to climb a summit at night.

The day on the hill

A poor day on the tops of Pen-y-ghent, with a blustery wind and drizzle for much of the day.

Wind

On the summit expect a south-westerly wind of 20–35 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 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 60–70 mph.

Cloud and visibility

The tops should stay clear of cloud all day.

Rain and ground

Drizzle for much of the day. Expect 2–5 mm in total. It will be wet underfoot after recent rain.

Warmth and kit

On the tops it will be around 4 to 8°C, feeling like -2 to 2°C in the wind. The freezing level is above the summits. A windproof and an extra layer for stops will help. Pack waterproofs too, and keep a warm layer dry in your pack.

Daylight

Sunset is around 4:45pm, 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 28 October 2026

Full overnight outlook

A mixed night to camp, mainly because of the rain. Gusts reach about 25 mph on open ground, so peg out well and use the guylines. Look for shelter from the west. Expect some light rain, mostly early on, so you'll likely pitch in the rain. The air is damp at every height we checked (300-600 m), so expect heavy condensation. Leave the vents open. A cold night, down to about 2°C around 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.

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.

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

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 sandstone, a gritty sedimentary rock. It is rough and grippy when dry and can feel greasy when damp or covered in lichen. It is usually solid in terraced steps, but softer layers crumble and weathered edges can break away. On the usual routes up you may also cross limestone, which grips well where it is rough, but polished limestone is glassy and is very slippery 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.

Sandstone is a gritty sedimentary rock. It is rough and grippy when dry and can feel greasy when damp or covered in lichen. It is usually solid in terraced steps, but softer layers crumble and weathered edges can break away. 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.
