Sgùrr nan Eugallt weather forecast.

A mixed day on Sgùrr nan Eugallt: summit wind broadly 10-30 mph, with gusts 30-40 mph early in the morning (strong winds). Much calmer lower down - generally 5-15 mph in the valley, rising towards the tops. Any cloud sits well above the tops (base 1200-1500 m) - clear summits. Little or no rain expected.

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

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

A grey, cloudy day on Sgùrr nan Eugallt: summit wind broadly 10-25 mph, with gusts 25-35 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. Much calmer lower down - generally 0-10 mph in the valley, rising towards the tops. Cloud base around 400–700 m through the morning, lifting to 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 (forecast models agree on the walking impact of the wind) - the summit peak could reasonably be 16-27 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 40% later.

A grey, cloudy day on Sgùrr nan Eugallt: 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 800–1100 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. 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 grey, cloudy day on Sgùrr nan Eugallt: summit wind broadly 10-25 mph, with gusts 20-30 mph during the evening (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. Much calmer lower down - generally 0-10 mph in the valley, rising towards the tops. Cloud base around 600–900 m in the morning, then around 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. Some rain is likely, with around 5-10 mm indicated; timing and local totals remain uncertain. Confidence moderate (Summit wind could be roughly 14-26 mph, which changes how difficult exposed walking may feel) - the summit peak could reasonably be 14-26 mph, so treat the headline as mid-range.

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

A rough, clagged-in day on Sgùrr nan Eugallt: summit wind broadly 10-40 mph, with gusts 45-55 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. 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 03:00 the following day. Much calmer lower down - generally 0-10 mph in the valley, rising towards the tops. Cloud base around 600–900 m in the morning, lowering to 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 10-20 mm indicated; local totals could vary considerably. Low confidence (Summit wind could be roughly 20-47 mph, which changes how difficult exposed walking may feel) - the summit peak could be anywhere from 20 to 47 mph; check again nearer the time.

Forecast confidence: Summit wind could be roughly 17-43 mph, which changes how difficult exposed walking may feel.

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

A grey, cloudy day on Sgùrr nan Eugallt: summit wind broadly 20-35 mph, with gusts 35-45 mph during the afternoon (strong winds). The ground is likely to be wet after recent rain. 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 through the morning, lifting to 1100–1400 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 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 17-43 mph, which changes how difficult exposed walking may feel) - the summit peak could reasonably be 17-43 mph, so treat the headline as mid-range.
