Seat Sandal weather forecast.

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

Cloud-free timing: Cloudy early, clearing later.

A mixed day on Seat Sandal: summit wind broadly 15-35 mph, with gusts 35-45 mph early in the morning (gale-force winds). Thunderstorms are a significant hazard from around midday into the evening. Exposed summits and ridges are a poor choice while storms are nearby. Much calmer lower down - generally 5-15 mph in the valley, rising towards the tops. Any cloud sits well above the tops (base 1400-2000 m) - clear summits. Cloud is likely to hang lowest on southeastern slopes; the northwestern 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.

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

Cloud-free timing: Best around midday at about 50%; lowest later at about 20%.

A wild day on Seat Sandal: summit wind broadly 10-35 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 500–800 m in the morning, then around 700–1000 m around midday and 400–700 m by late afternoon. The top is likely to drift in and out of cloud, with the best chance of a view during the morning. A persistently wet day is possible, with around 5-10 mm indicated; local totals could vary considerably. Confidence moderate (Summit wind could be roughly 22-35 mph, which changes how difficult exposed walking may feel) - the summit peak could reasonably be 22-35 mph, so treat the headline as mid-range.

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

A grey, cloudy day on Seat Sandal: summit wind broadly 10-30 mph, with gusts 25-35 mph during the evening (strong winds). 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 5-15 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. Some rain is likely, with around 2-5 mm indicated; timing and local totals remain uncertain. Confidence moderate (Summit wind could be roughly 15-30 mph, which changes how difficult exposed walking may feel) - the summit peak could reasonably be 15-30 mph, so treat the headline as mid-range.

A rough, clagged-in day on Seat Sandal: summit wind broadly 5-20 mph, with gusts 15-25 mph early in the morning (a moderate breeze). 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 14:00 until around 03:00 the following day. Cloud base around 100–400 m in the morning, then around 600–900 m around midday and 400–700 m by late afternoon. Expect clag for much of the day, though a brief clearance is possible around midday.

A rough, clagged-in day on Seat Sandal: 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 early morning into the evening. Avoid committing to exposed ridges if storms begin to build. 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 03:00 the following day. 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 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. Confidence moderate (Summit wind could be roughly 16-31 mph, which changes how difficult exposed walking may feel) - the summit peak could reasonably be 16-31 mph, so treat the headline as mid-range.

A wild day on Seat Sandal: summit wind broadly 20-40 mph, with gusts 45-55 mph during the evening (gale-force winds). A meaningful thunderstorm risk is indicated from early morning into the evening.
