Sgùrr Mòr weather forecast.

Cloud-free timing: Cloudy early, clearing later.

A mixed day on Sgùrr Mòr: summit wind broadly 10-25 mph, with gusts 25-35 mph during the afternoon (fresh and blowy). Thunder watch from late afternoon into the evening: a small but credible risk is present. Watch for growing clouds and leave exposed tops if thunder develops. Cloud base around 1000–1300 m in the morning, then around 0–300 m around midday and 1000–1300 m by late afternoon. Summit cloud should lift later, bringing a better chance of clear views. Little or no rain expected.

A grey, cloudy day on Sgùrr Mòr: summit wind broadly 10-25 mph, with gusts 25-35 mph early in the morning (fresh and blowy). Much calmer lower down - generally 0-10 mph in the valley, rising towards the tops. Cloud base mostly around 400–700 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 northeastern slopes; the southwestern 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 (forecast models agree on the walking impact of the wind) - the summit peak could reasonably be 15-28 mph, so treat the headline as mid-range.

Forecast confidence: Rain is possible, but forecast models differ by about 12 hours on when it arrives.

A grey, cloudy day on Sgùrr Mòr: summit wind broadly 5-20 mph, with gusts 15-25 mph during the afternoon (a moderate breeze). Cloud base mostly around 400–700 m through daylight. Expect the top to stay in cloud for most or all of daylight, with no dependable break. Some rain is likely, with up to around 2 mm indicated; timing and local totals remain uncertain. 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.

A rough, clagged-in day on Sgùrr Mòr: summit wind broadly 5-20 mph, with gusts 15-25 mph during the afternoon (fresh and blowy). A meaningful thunderstorm risk is indicated from around midday 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 600–900 m through the morning, lowering to 400–700 m by late afternoon. Expect the top to stay in cloud for most or all of daylight, with no dependable break. A persistently wet day is possible, with around 10-20 mm indicated; local totals could vary considerably.

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 Sgùrr Mòr: summit wind broadly 5-20 mph, with gusts 20-30 mph early in the morning (fresh and blowy). A meaningful thunderstorm risk is indicated from early 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, lifting to 500-800 m around midday. Expect clag for much of the day, though a brief clearance is possible during the evening. Some rain is likely, with around 2-5 mm indicated; timing and local totals remain uncertain. Confidence moderate (Summit wind could be roughly 8-27 mph, which changes how difficult exposed walking may feel) - the summit peak could reasonably be 8-27 mph, so treat the headline as mid-range.

Forecast confidence: Rain is possible, but forecast models differ by about 14 hours on when it arrives.

A rough, clagged-in day on Sgùrr Mòr: summit wind broadly 20-35 mph, with gusts 35-45 mph during the morning (gale-force winds). 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 17:00. Much calmer lower down - generally 5-15 mph in the valley, rising towards the tops. Cloud base around 400–700 m in the morning, lifting to 700–1000 m around midday and 900–1200 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. A persistently wet day is possible, with around 5-10 mm indicated; local totals could vary considerably. Cold on top: air temperature broadly 2 to 6°C, feeling around -4 to 0°C in the wind - wrap up. Confidence moderate (Summit wind could be roughly 20-36 mph, which changes how difficult exposed walking may feel) - the summit peak could reasonably be 20-36 mph, so treat the headline as mid-range.
