Sgùrr na Banachdich weather forecast.

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

A mixed day on Sgùrr na Banachdich: summit wind broadly 5-30 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 1100-3100 m) - clear summits. Little or no rain expected.

Forecast confidence: Summit wind could be roughly 20-37 mph, which changes how difficult exposed walking may feel.

A grey, cloudy day on Sgùrr na Banachdich: summit wind broadly 10-30 mph, with gusts 30-40 mph during the evening (strong winds). Much calmer lower down - generally 5-15 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. Little or no rain expected. Confidence moderate (Summit wind could be roughly 20-37 mph, which changes how difficult exposed walking may feel) - the summit peak could reasonably be 20-37 mph, so treat the headline as mid-range. 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: Rain is possible, but forecast models differ by about 18 hours on when it arrives.

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 10-20 mm indicated; local totals could vary considerably. Confidence moderate (Summit wind could be roughly 14-31 mph, which changes how difficult exposed walking may feel) - the summit peak could reasonably be 14-31 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 na Banachdich: summit wind broadly 5-35 mph, with gusts 35-45 mph during the evening (strong winds). Thunderstorms are a significant hazard from early morning into the evening. Exposed summits and ridges are a poor choice while storms are nearby. 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 02:00 until around 03:00 the following day. Much calmer lower down - generally 0-10 mph in the valley, rising towards the tops. Cloud base mostly around 300–600 m through daylight. 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. Confidence moderate (Summit wind could be roughly 16-39 mph, which changes how difficult exposed walking may feel) - the summit peak could reasonably be 16-39 mph, so treat the headline as mid-range.

Forecast confidence: Summit wind could be roughly 37-68 mph, which changes how difficult exposed walking may feel.

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

A rough, clagged-in day on Sgùrr na Banachdich: summit wind broadly 30-55 mph, with gusts 65-75 mph early in the morning (storm-force 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 10-20 mph in the valley, rising towards the tops. Cloud base around 400–700 m through the morning, lifting to 700–1000 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 northern slopes; the southern 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. Cold on top: air temperature broadly 2 to 6°C, feeling around -2 to 2°C in the wind - wrap up. Low confidence (Summit wind could be roughly 37-68 mph, which changes how difficult exposed walking may feel) - the summit peak could be anywhere from 37 to 68 mph; check again nearer the time.
