Sgùrr Mhurlagain weather forecast.

Cloud-free timing: Around 67% early, improving to around 100% later.

A mixed day on Sgùrr Mhurlagain: summit wind broadly 10-30 mph, with gusts 30-40 mph early in the morning (strong winds). Much calmer lower down - generally 0-10 mph in the valley, rising towards the tops. Any cloud sits well above the tops (base 1000-2000 m) - clear summits. Little or no rain expected.

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 Sgùrr Mhurlagain: summit wind broadly 10-30 mph, with gusts 30-40 mph early in the morning (strong winds). A meaningful thunderstorm risk is indicated during 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 400–700 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 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 (Summit wind could be roughly 20-34 mph, which changes how difficult exposed walking may feel) - the summit peak could reasonably be 20-34 mph, so treat the headline as mid-range.

Forecast confidence: Rain is possible, but forecast models differ by about 8 hours on when it arrives.

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

A mixed day on Sgùrr Mhurlagain: summit wind broadly 0-15 mph, with gusts 5-15 mph early in the morning (a moderate breeze). Cloud base around 400–700 m in the morning, lifting to 600–900 m around midday and 900–1200 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. 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 Mhurlagain: summit wind broadly 10-20 mph, with gusts 20-30 mph around midday (fresh and blowy). Thunderstorms are a significant hazard from the morning into the evening. Exposed summits and ridges are a poor choice while storms are nearby. 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 400–700 m around midday and 600–900 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 southern slopes; the northern 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.

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

A rough, clagged-in day on Sgùrr Mhurlagain: summit wind broadly 10-40 mph, with gusts 40-50 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 500–800 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 southwestern slopes; the northeastern 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. Low confidence (Summit wind could be roughly 20-58 mph, which changes how difficult exposed walking may feel) - the summit peak could be anywhere from 20 to 58 mph; check again nearer the time.

Forecast confidence: Summit wind could be roughly 18-36 mph, which changes how difficult exposed walking may feel.

Cloud-free timing: Around 0% early, improving to around 80% later.

A grey, cloudy day on Sgùrr Mhurlagain: summit wind broadly 15-35 mph, with gusts 35-45 mph during the afternoon (gale-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 400–700 m in the morning, lifting to 700–1000 m around midday and 800–1100 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 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. Cold on top: air temperature broadly 4 to 8°C, feeling around 0 to 4°C in the wind - wrap up. Confidence moderate (Summit wind could be roughly 18-36 mph, which changes how difficult exposed walking may feel) - the summit peak could reasonably be 18-36 mph, so treat the headline as mid-range.
