Càrn an Tuirc weather forecast.

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

Cloud-free timing: Around 0% early, improving to around 40% later.

A grey, cloudy day on Càrn an Tuirc: summit wind broadly 10-25 mph, with gusts 20-30 mph during the morning (fresh and blowy). Cloud base around 500–800 m in the morning, then around 1000–1300 m around midday and 700–1000 m by late afternoon. 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.

A grey, cloudy day on Càrn an Tuirc: 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 400–700 m in the morning, then around 800–1100 m around midday and 400–700 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 northern slopes; the southern 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. 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.

Cloud-free timing: Around 0% early, improving to around 100% later.

A mixed day on Càrn an Tuirc: summit wind broadly 5-15 mph, with gusts 10-20 mph during the afternoon (a moderate breeze). Thunderstorms are possible from around midday 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 900–1200 m around midday and 1800–2100 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. Little or no rain expected.

A grey, cloudy day on Càrn an Tuirc: summit wind broadly 10-25 mph, with gusts 20-30 mph during the afternoon (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 400–700 m in the morning, lifting to 600–900 m around midday and 700–1000 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 southwestern slopes; the northeastern 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. Confidence moderate (Summit wind could be roughly 11-26 mph, which changes how difficult exposed walking may feel) - the summit peak could reasonably be 11-26 mph, so treat the headline as mid-range.

Cloud-free timing: Around 0% early, improving to around 40% later.

A mixed day on Càrn an Tuirc: summit wind broadly 5-35 mph, with gusts 35-45 mph during the evening (gale-force winds). A meaningful thunderstorm risk is indicated from the morning into the evening. 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 300–600 m in the morning, then around 1700–2000 m around midday and 700–1000 m by late afternoon. The top is likely to drift in and out of cloud, with the best chance of a view from the morning into the afternoon. Some rain is likely, with around 2-5 mm indicated; timing and local totals remain uncertain. Low confidence (Summit wind could be roughly 18-48 mph, which changes how difficult exposed walking may feel) - the summit peak could be anywhere from 18 to 48 mph; check again nearer the time. 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: Summit wind could be roughly 32-50 mph, which changes how difficult exposed walking may feel.

A rough, clagged-in day on Càrn an Tuirc: summit wind broadly 35-45 mph, with gusts 50-60 mph early in the morning (storm-force winds). Much calmer lower down - generally 10-20 mph in the valley, rising towards the tops. Cloud base mostly around 700–1000 m through daylight. Expect the top to stay in cloud for most or all of daylight, with no dependable break. 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. Confidence moderate (Summit wind could be roughly 32-50 mph, which changes how difficult exposed walking may feel) - the summit peak could reasonably be 32-50 mph, so treat the headline as mid-range.
