Sàileag weather forecast.

Cloud-free timing: Cloudy early, clearing later.

A mixed day on Sàileag: summit wind broadly 20-30 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. Little or no rain expected. Confidence moderate (forecast models agree on the walking impact of the wind) - the summit peak could reasonably be 25-28 mph, so treat the headline as mid-range.

A wild day on Sàileag: summit wind broadly 10-25 mph, with gusts 20-30 mph early in the morning (fresh and blowy). Thunder watch from around midday into the evening: a small but credible risk is present. Watch for growing clouds and leave exposed tops if thunder develops. There could be a spate risk based on forecast rainfall. Burns and unbridged crossings may rise quickly. Most likely from around 19:00 until around 00:00 the following day. Any cloud sits well above the tops (base 1200-1500 m) - clear summits. A persistently wet day is possible, with around 5-10 mm indicated; local totals could vary considerably.

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

A grey, cloudy day on Sàileag: summit wind broadly 10-30 mph, with gusts 30-40 mph early in the morning (strong winds). Thunderstorms are possible from around midday into the evening. Keep an escape route from exposed ridges and descend if thunder develops. Much calmer lower down - generally 5-15 mph in the valley, rising towards the tops. Cloud base around 700–1000 m in the morning, lowering to 600–900 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 northeastern slopes; the southwestern 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 20-33 mph, which changes how difficult exposed walking may feel) - the summit peak could reasonably be 20-33 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 Sàileag: summit wind broadly 0-15 mph, with gusts 5-15 mph during the evening (a moderate breeze). 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 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 Sàileag: 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. 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 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 grey, cloudy day on Sàileag: summit wind broadly 5-30 mph, with gusts 35-45 mph during the evening (strong 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 700–1000 m in the morning, lowering to 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 southwestern slopes; the northeastern 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. Low confidence (Summit wind could be roughly 16-47 mph, which changes how difficult exposed walking may feel) - the summit peak could be anywhere from 16 to 47 mph; check again nearer the time.

Forecast confidence: Summit wind could be roughly 17-36 mph, which changes how difficult exposed walking may feel.

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

A grey, cloudy day on Sàileag: summit wind broadly 15-35 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 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. 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 5-10 mm indicated; timing and local totals remain uncertain. Cold on top: air temperature broadly 4 to 8°C, feeling around -2 to 2°C in the wind - wrap up. Confidence moderate (Summit wind could be roughly 17-36 mph, which changes how difficult exposed walking may feel) - the summit peak could reasonably be 17-36 mph, so treat the headline as mid-range.
