The day on the hill

Light winds on Beinn Airigh Charr. Cloud could cover the tops and limit the views.

Wind

On the summit expect light winds of up to 15 mph, mainly northerly, with gusts of 15–25 mph at the windiest. Lower down on the open hillside the wind will be light, under 5 mph.

Cloud and visibility

Clear spells are more likely early, with a greater risk of summit cloud later. Forecast models differ on how much summit cloud develops. The cloud base could be as low as 500–800 m mid-afternoon.

Rain and ground

Drizzle sets in mid-afternoon.

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 above the summits. 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

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 1.7 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.

Generic exposed-rock guidance

Full climbing & scrambling outlook

Mixed conditions for exposed scrambling. The rock is likely to be wet and slippery through the day. Cloud on the tops may make route-finding and retreat harder. The rock around the summit is mostly basalt, a dark volcanic rock. It grips well when dry and can be very slippery when wet. It is often blocky and shattered, with loose rubble on ledges. 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 Beinn Airigh Charr, though expect sleet or snow on the tops.

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 800 to 1000 m above sea level. Snow can fall below this, but its lower limit is uncertain.

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.

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 500–800 m mid-afternoon. The air should be clear, so expect far-reaching views as long as the tops stay clear.

Rain and ground

A band of sleet moves in around midday. Expect up to 2 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 -8 to -4°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 4:15pm, so allow time to get off the hill before dark, and carry a head torch.

Forecast confidence

Some of the detail could still change, so have a last look at the forecast in the morning before you set off.

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. The rock around the summit is mostly basalt, a dark volcanic rock. It grips well when dry and can be very slippery when wet. It is often blocky and shattered, with loose rubble on ledges. 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 Beinn Airigh Charr, 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 700 to 900 m above sea level. Snow can fall below this, but its lower limit is uncertain. There is a risk of blizzard conditions in the morning, when snow and strong winds coincide. Paths and footprints can quickly disappear beneath falling and blowing snow. 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 northerly 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 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

The tops are likely to stay mostly clear of cloud, though brief patches cannot be ruled out. Where snow covers the ground, the sky and hillside can merge into a featureless white view, making it difficult to judge slope or direction. Do not rely on following a visible path. Avoid exposed routes if you cannot navigate safely in these conditions, and turn back before visibility deteriorates.

Rain and ground

Sleet and snow for much of the day. Expect 2–5 mm in total, measured as melted water, so any snow would lie deeper. The timing could shift by a few hours.

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 4:10pm, 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 day on the hill

A poor day on the tops of Beinn Airigh Charr, 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 700 to 1000 m above sea level. Snow can fall below this, but its lower limit is uncertain.

Wind

On the summit expect a westerly wind of around 15–25 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.

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.

Rain and ground

A band of sleet and snow moves in mid-morning. 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 -8 to -4°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 4:10pm, so allow time to get off the hill before dark, and carry a head torch.

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 35–45 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 basalt, a dark volcanic rock. It grips well when dry and can be very slippery when wet. It is often blocky and shattered, with loose rubble on ledges. 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 Beinn Airigh Charr, with strong, gusty winds and drizzle for much of the day.

Wind

On the summit expect a south-westerly wind of 30–40 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 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 55–65 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. The cloud base could be as low as 400–700 m mid-afternoon. Visibility may drop briefly in showers.

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 -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.

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.

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 18 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 4°C at 600 m. A 3-season bag rated to about 2°C comfort, and a warm mat, should do. Allow more if you sleep cold.

The day on the hill

A mixed day on Beinn Airigh Charr, with a blustery wind and drizzle 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 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 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 70–80 mph.

Cloud and visibility

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

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 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. 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

Cloud heights are particularly hard to pin down today. It's still five days off and could change, so check again nearer the time.

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 southwest. The wind swings from southwesterly to northwesterly overnight, so a pitch sheltered at dusk may not be by morning. Expect about 7 mm of rain, with rain while you pitch and still falling when you pack up. A cold night, down to about 0°C around 300 m.

The day on the hill

A mixed day on Beinn Airigh Charr, with snow on the tops.

Snow and navigation

Snow is forecast on the tops in the afternoon. The air freezing level is roughly 500 to 600 m above sea level. Snow can fall below this, but its lower limit is uncertain. The forecast model suggests around 1 cm of fresh snowfall at around 700 m between 09:00 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 westerly wind of 10–25 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.

Cloud and visibility

The tops should stay mostly clear of cloud. 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. Visibility may drop briefly in showers.

Rain and ground

A band of snow moves in around midday. 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 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 4:05pm, 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.
