The day on the hill

A fine day on Beinn Odhar Bheag: dry, with light winds and clear tops for most of the day.

Wind

On the summit expect light winds of up to 15 mph, mainly north-easterly, with gusts of 10–20 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 -2 to 2°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.

Daylight

A short day, with only about 8 hours of daylight. Sunset is around 4:20pm, so allow time to get off the hill before dark, and carry a head torch.

Full climbing & scrambling outlook

Excellent 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. 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 fine day on Beinn Odhar Bheag: light winds and clear tops for most of the day, though expect sleet or snow on the tops.

Snow and navigation

Sleet or snow is possible on the tops in the 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 northerly wind of 10–20 mph for most of the day, with gusts of 15–25 mph at the windiest. Lower down on the open hillside the wind will be light, under 10 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

Snow arrives mid-afternoon. 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 -4 to 0°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 4:20pm, so allow time to get off the hill before dark, and carry a head torch.

Full overnight outlook

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. Look for shelter from the north. Dry to pitch, then a little rain overnight, easing by morning, though the tent may still be 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.

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. 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 good day on Beinn Odhar Bheag, though expect snow on the tops and a bitter wind chill.

Snow and navigation

Snow is forecast on the tops in the morning. The air freezing level is roughly 500 to 600 m above sea level. Snow can fall below this, but its lower limit is uncertain.

Wind

On the summit expect a northerly 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 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

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

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 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. 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

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

The day on the hill

A mixed day on Beinn Odhar Bheag, with sleet or snow on the tops.

Snow and navigation

Sleet or snow is possible on the tops in the afternoon, with small temperature changes affecting the mix. The air freezing level is roughly 900 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 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. 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 start clear, but the cloud comes down onto them in the early afternoon. The cloud base could be as low as 500–800 m mid-afternoon.

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 through the middle of the day.

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. 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

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.

A poor night to camp on open ground. Gusts reach about 40 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. Expect about 6 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. 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. 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. 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. 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

A poor day on the tops of Beinn Odhar Bheag, 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 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

Expect the summit to be in cloud for most of the day. The cloud base could be as low as 500–800 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

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

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 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

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 2.5 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.

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.

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 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 heavy rain, around 20 mm, 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 2°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.

The day on the hill

On Beinn Odhar Bheag, with rain for much of the day and a blustery wind. Cloud could cover the tops and limit the views.

Things to watch

Burns could rise quickly from the afternoon into the night. Timings are rough. Turn back if a crossing looks unsafe.

Wind

On the summit expect a south-westerly wind of 15–30 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. 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 lowers through the day. A few forecast models bring the cloud base down to around 300–600 m at times. The cloud base sits close to summit height, so the top could go in and out of cloud at short notice. 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. 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 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. 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

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

The day on the hill

Light winds on Beinn Odhar Bheag, with snow on the tops. Cloud could cover the tops and limit the views.

Snow and navigation

Snow is forecast on the tops in the afternoon. The air freezing level is roughly 600 to 800 m above sea level. Snow can fall below this, but its lower limit is uncertain.

Wind

On the summit expect a westerly wind of 5–20 mph for most of the day, with gusts of 15–25 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. The cloud base sits close to summit height, so the top could go in and out of cloud at short notice. Patchy mist is possible in sheltered valleys early on.

Rain and ground

A band of snow moves in during the early afternoon. Expect up to 2 mm in total, measured as melted water, so any snow would lie deeper. The ground is very wet after recent rain, so expect boggy paths.

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. 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

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

Full overnight outlook

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 40 mph around 900 m and nearer 25 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 southwesterly to southeasterly 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. 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. 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. The ground will be sodden after recent rain, so pick a firm, well-drained pitch.

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. 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. 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.

Recommended kit for this dayWeather-aware packing prompts, plus your core hillwalking kitView kit

For a day hillwalk, not a complete route-specific checklist. Carry navigation and backup you can use, warm and waterproof layers, suitable footwear, food and water, a headtorch, emergency shelter, first aid and a way to call for help. Snow, ice, technical terrain and overnight trips need additional equipment and skills.
