A fine day on Ben Aden: 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 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 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 9 hours of daylight. Sunset is around 4:30pm, so allow time to get off the hill before dark, and carry a head torch.
Sunshine context Model-grid estimate, not summit sunshine
The surrounding model grid indicates 5.5 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.

Full overnight outlook
A mixed night to camp, mainly because of the cold. Light winds on open ground, gusting no more than about 20 mph. It should stay dry. Overnight lows of about 3°C at 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.
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 schist, a flaky, mica-rich rock that splits into layers. It has only fair grip when dry and is slippery when wet, as the mica gives it a greasy sheen. It splits easily along its layers, so flakes and ledges can be loose, and it is often grassy and vegetated. 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 Ben Aden: dry, with light winds and clear tops for most of the day.
Wind
On the summit expect a south-easterly wind of 5–25 mph for most of the day, with gusts of 20–30 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 drift in and out of cloud, with the best chance of a clear summit early in the morning. 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. 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
A short day, with only about 9 hours of 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. Some of the detail could still change, so have a last look at the forecast in the morning before you set off.

The day on the hill
A good day on Ben Aden: light winds.
Wind
On the summit expect light winds of up to 15 mph, mainly westerly, with gusts of 10–20 mph at the windiest.
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. Mist or fog is possible in the valleys through the morning. It looks hazy, so views may be limited even when the tops are clear.
Rain and ground
Drizzle sets in around midday.
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. 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
Cloud heights are particularly hard to pin down today. It's still five days off and could change, so check again nearer the time.
Sunshine context Model-grid estimate, not summit sunshine
The surrounding model grid indicates 3.9 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 Monday 9 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. The wind swings from westerly to northerly overnight, so a pitch sheltered at dusk may not be by morning. It should stay dry. 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 0°C. 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.
Poor 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 schist, a flaky, mica-rich rock that splits into layers. It has only fair grip when dry and is slippery when wet, as the mica gives it a greasy sheen. It splits easily along its layers, so flakes and ledges can be loose, and it is often grassy and vegetated. These are general notes for each rock type, taken from geological maps around the summit, so the rock on your line may differ.

Schist is a flaky, mica-rich rock that splits into layers. It has only fair grip when dry and is slippery when wet, as the mica gives it a greasy sheen. It splits easily along its layers, so flakes and ledges can be loose, and it is often grassy and vegetated.

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.

The day on the hill
A fine day on Ben Aden: dry, with light winds.
Wind
On the summit expect light winds of up to 10 mph, mainly south-easterly, with gusts of 5–15 mph at the windiest.
Cloud and visibility
The tops should stay mostly clear of cloud. A few forecast models bring the cloud base down to around 700–1000 m at times. The cloud base sits close to summit height, so the top could go in and out of cloud at short notice. Good spells of sunshine are likely. 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 -4 to 0°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 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
It's still seven days off and could change, so check again nearer the time.
