The day on the hill

Dry, with light winds on Ben Rinnes. Cloud could cover the tops and limit the views.

Wind

On the summit expect light winds of up to 15 mph, mainly north-westerly, with gusts of 10–20 mph at the windiest.

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.

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.

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

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 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. Expect a little 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. The air is damp at every height we checked (300-900 m), so expect heavy condensation. Leave the vents open. A frost up around 900 m, down to about -2°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.

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 -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.

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

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 granite, a coarse, crystalline rock. It has excellent friction when dry and clean and is fair when wet, but greasy where there is lichen or moss. It is generally solid, but weathers into rounded slabs and blocks, and loose granite grit on slabs can roll underfoot like ball bearings. These are general notes for each rock type, taken from geological maps around the summit, so the rock on your line may differ.

Granite is a coarse, crystalline rock. It has excellent friction when dry and clean and is fair when wet, but greasy where there is lichen or moss. It is generally solid, but weathers into rounded slabs and blocks, and loose granite grit on slabs can roll underfoot like ball bearings. 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 good day on Ben Rinnes, though expect snow on the tops.

Snow and navigation

Snow is forecast on the tops in the afternoon. The air freezing level is roughly 800 to 900 m above sea level. Snow can fall below this, but its lower limit is uncertain. The forecast model suggests less than 1 cm of fresh snowfall at around 800 m between 08:00 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 north-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 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. Some forecast models keep it drier in the afternoon.

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 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

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 granite, a coarse, crystalline rock. It has excellent friction when dry and clean and is fair when wet, but greasy where there is lichen or moss. It is generally solid, but weathers into rounded slabs and blocks, and loose granite grit on slabs can roll underfoot like ball bearings.

The day on the hill

A poor day on the tops of Ben Rinnes, with snow on the tops and a bitter wind chill.

Snow and navigation

Snow is forecast on the tops during the morning and afternoon. The air freezing level is roughly 600 to 900 m above sea level. Snow can fall below this, but its lower limit is uncertain. The forecast model suggests less than 1 cm of fresh snowfall at around 800 m between 08:00 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 north-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

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

Rain and ground

Snow at first, clearing by mid-morning. Some forecast models keep it drier in the afternoon.

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. 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 4:05pm, 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 two days off and could change, so check again nearer the time.

The day on the hill

A mixed day on Ben Rinnes, with a blustery wind.

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. It gets windier still after dark, with summit gusts of 40–50 mph, so bear that in mind if you will be out late.

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 500–800 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

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.

Generic exposed-rock guidance

Full climbing & scrambling outlook

Very 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 35–45 mph could throw you off balance on exposed moves and ridges. The rock around the summit is mostly granite, a coarse, crystalline rock. It has excellent friction when dry and clean and is fair when wet, but greasy where there is lichen or moss. It is generally solid, but weathers into rounded slabs and blocks, and loose granite grit on slabs can roll underfoot like ball bearings. These are general notes for each rock type, taken from geological maps around the summit, so the rock on your line may differ.

Granite is a coarse, crystalline rock. It has excellent friction when dry and clean and is fair when wet, but greasy where there is lichen or moss. It is generally solid, but weathers into rounded slabs and blocks, and loose granite grit on slabs can roll underfoot like ball bearings. 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 Ben Rinnes, with strong, gusty winds.

Wind

On the summit expect a 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 5–15 mph. Gusts like that are strong enough to knock you off balance, so take care near edges and on narrow ridges.

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 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.

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

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.

The day on the hill

A mixed day on Ben Rinnes, with very strong, gusty winds.

Wind

On the summit expect a westerly wind of around 35–45 mph first thing, easing to 25–35 mph by mid-afternoon, with gusts of 50–60 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 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 85–95 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 sets in during the early 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.

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.

The day on the hill

Dry and breezy on Ben Rinnes. Cloud could cover the tops and limit the views.

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

Clear spells are possible, but cloud could cover the tops for part of the day. Forecast models differ on how much summit cloud develops. Patchy mist is possible in sheltered valleys early on.

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 -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.

Poor conditions for exposed scrambling. The rock should be drying, but damp patches, shaded holds and drainage lines may still be wet. 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 granite, a coarse, crystalline rock. It has excellent friction when dry and clean and is fair when wet, but greasy where there is lichen or moss. It is generally solid, but weathers into rounded slabs and blocks, and loose granite grit on slabs can roll underfoot like ball bearings.
