Stùcd an Lochain weather forecast.

Cloud-free timing: Around 0% early, improving to around 20% later.

A grey, cloudy day on Stùcd an Lochain: summit wind broadly 20-35 mph, with gusts 35-45 mph during the morning (strong winds). Much calmer lower down - generally 5-15 mph in the valley, rising towards the tops. Cloud base around 500-800 m in the morning, lifting to 800-1100 m around midday. The top is likely to drift in and out of cloud, with the best chance of a view during the afternoon. Cloud is likely to hang lowest on southeastern slopes; the northwestern side should see somewhat higher bases and better breaks. Little or no rain expected.

Cloud-free timing: Best around midday at about 50%; around 0% early and 0% later.

A grey, cloudy day on Stùcd an Lochain: summit wind broadly 20-30 mph, with gusts 30-40 mph during the evening (strong winds). Much calmer lower down - generally 5-15 mph in the valley, rising towards the tops. Cloud base around 500–800 m in the morning, then around 900–1200 m around midday and 700–1000 m by late afternoon. Expect clag for much of the day, though a brief clearance is possible from midday into the afternoon. Cloud is likely to hang lowest on eastern slopes; the western side should see somewhat higher bases and better breaks. Little or no rain expected. Confidence moderate (forecast models agree on the walking impact of the wind) - the summit peak could reasonably be 22-29 mph, so treat the headline as mid-range. Cloud base is the least certain part of this - the models are only moderately agreed, so it could sit a couple of hundred metres either way.

Forecast confidence: Thunderstorm timing is inherently uncertain and may shift by several hours.

Cloud-free timing: Around 0% early, improving to around 20% later.

A grey, cloudy day on Stùcd an Lochain: summit wind broadly 10-25 mph, with gusts 25-35 mph early in the morning (fresh and blowy). A meaningful thunderstorm risk is indicated from the morning into the afternoon. Avoid committing to exposed ridges if storms begin to build. Much calmer lower down - generally 0-10 mph in the valley, rising towards the tops. Cloud base around 700–1000 m in the morning, then around 800–1100 m around midday and 600–900 m by late afternoon. Expect clag for much of the day, though a brief clearance is possible during the evening. Cloud is likely to hang lowest on northern slopes; the southern side should see somewhat higher bases and better breaks. Some rain is likely, with up to around 2 mm indicated; timing and local totals remain uncertain. Confidence moderate (Summit wind could be roughly 12-25 mph, which changes how difficult exposed walking may feel) - the summit peak could reasonably be 12-25 mph, so treat the headline as mid-range.

Forecast confidence: A low thunderstorm risk remains difficult to time precisely.

A grey, cloudy day on Stùcd an Lochain: summit wind broadly 10-20 mph, with gusts 15-25 mph early in the morning (fresh and blowy). Thunderstorms are possible from the morning into the evening. Keep an escape route from exposed ridges and descend if thunder develops. Cloud base around 400-700 m in the morning, lifting to 600-900 m around midday. Expect the top to stay in cloud for most or all of daylight, with no dependable break. Some rain is likely, with around 2-5 mm indicated; timing and local totals remain uncertain.

Forecast confidence: Thunderstorm timing is inherently uncertain and may shift by several hours.

Cloud-free timing: Around 0% early, improving to around 60% later.

A grey, cloudy day on Stùcd an Lochain: summit wind broadly 10-25 mph, with gusts 20-30 mph around midday (fresh and blowy). A meaningful thunderstorm risk is indicated from the morning into the evening. Avoid committing to exposed ridges if storms begin to build. Cloud base around 700–1000 m through the morning, lifting to 1300–1600 m by late afternoon. The top is likely to drift in and out of cloud, with the best chance of a view from late afternoon into the evening. Cloud is likely to hang lowest on southern slopes; the northern side should see somewhat higher bases and better breaks. Some rain is likely, with around 2-5 mm indicated; timing and local totals remain uncertain.

Forecast confidence: Thunderstorm timing is inherently uncertain and may shift by several hours.

A rough, clagged-in day on Stùcd an Lochain: summit wind broadly 15-50 mph, with gusts 55-65 mph during the evening (storm-force winds). Thunderstorms are a significant hazard from early morning into the evening. Exposed summits and ridges are a poor choice while storms are nearby. There could be a spate risk based on forecast rainfall. Burns and unbridged crossings may rise quickly. Most likely from around 00:00 until around 23:00. Much calmer lower down - generally 5-15 mph in the valley, rising towards the tops. Cloud base around 700–1000 m in the morning, then around 800–1100 m around midday and 300–600 m by late afternoon. Expect the top to stay in cloud for most or all of daylight, with no dependable break. Cloud is likely to hang lowest on western slopes; the eastern side should see somewhat higher bases and better breaks. Some rain is likely, with around 5-10 mm indicated; timing and local totals remain uncertain. Cold on top: air temperature broadly 6 to 10°C, feeling around -2 to 2°C in the wind - wrap up. Low confidence (Summit wind could be roughly 24-55 mph, which changes how difficult exposed walking may feel) - the summit peak could be anywhere from 24 to 55 mph; check again nearer the time.

Forecast confidence: Summit wind could be roughly 35-77 mph, which changes how difficult exposed walking may feel.

Cloud-free timing: Around 0% early, improving to around 60% later.

A rough, clagged-in day on Stùcd an Lochain: summit wind broadly 30-50 mph, with gusts 60-70 mph early in the morning (storm-force winds). The ground is likely to be wet after recent rain. Much calmer lower down - generally 5-15 mph in the valley, rising towards the tops. Cloud base around 800–1100 m in the morning, then around 600–900 m around midday and 1000–1300 m by late afternoon. The top is likely to drift in and out of cloud, with the best chance of a view during the evening. Cloud is likely to hang lowest on northwestern slopes; the southeastern side should see somewhat higher bases and better breaks. Some rain is likely, with around 2-5 mm indicated; timing and local totals remain uncertain. Cold on top: air temperature broadly 2 to 6°C, feeling around -6 to -2°C in the wind - wrap up. Low confidence (Summit wind could be roughly 35-77 mph, which changes how difficult exposed walking may feel) - the summit peak could be anywhere from 35 to 77 mph; check again nearer the time.
