Gairich weather forecast.

Cloud-free timing: Cloudy early, clearing later.

A mixed day on Gairich: summit wind broadly 10-30 mph, with gusts 30-40 mph during the afternoon (strong winds). Much calmer lower down - generally 5-15 mph in the valley, rising towards the tops. Cloud base around 500-800 m in the morning, lifting to 1500-1800 m around midday. Summit cloud should lift later, bringing a better chance of clear views. Little or no rain expected. Confidence moderate (forecast models agree on the walking impact of the wind) - the summit peak could reasonably be 21-26 mph, so treat the headline as mid-range.

Cloud-free timing: Cloudy early, clearing later.

A mixed day on Gairich: summit wind broadly 20-30 mph, with gusts 35-45 mph during the morning (strong winds). Much calmer lower down - generally 5-15 mph in the valley, rising towards the tops. Cloud base around 800-1100 m in the morning, lifting to 1100-1400 m around midday. Summit cloud should lift later, bringing a better chance of clear views. Little or no rain expected. Confidence moderate (forecast models agree on the walking impact of the wind) - the summit peak could reasonably be 23-29 mph, so treat the headline as mid-range.

Cloud-free timing: Cloudy early, clearing later.

A fine day on Gairich: summit wind broadly 5-25 mph, with gusts 20-30 mph early in the morning (fresh and blowy). Much calmer lower down - generally 0-10 mph in the valley, rising towards the tops. Any cloud sits well above the tops (base 900-1400 m) - clear summits. Little or no rain expected.

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

A grey, cloudy day on Gairich: summit wind broadly 5-20 mph, with gusts 20-30 mph during the evening (fresh and blowy). Cloud base around 400–700 m in the morning, then around 900–1200 m around midday and 600–900 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.

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

Cloud-free timing: Best around midday at about 50%; around 0% early and 0% later.

A grey, cloudy day on Gairich: summit wind broadly 0-15 mph, with gusts 5-15 mph early in the morning (a moderate breeze). Thunderstorms are possible from late afternoon into the evening. Keep an escape route from exposed ridges and descend if thunder develops. Cloud base around 600–900 m in the morning, then around 1300–1600 m around midday and 800–1100 m by late afternoon. Expect clag for much of the day, though a brief clearance is possible from midday into the afternoon. 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.

A grey, cloudy day on Gairich: summit wind broadly 5-15 mph, with gusts 10-20 mph during the afternoon (a moderate breeze). A meaningful thunderstorm risk is indicated from early morning into the evening. Avoid committing to exposed ridges if storms begin to build. Cloud base around 400–700 m in the morning, then around 800–1100 m around midday and 700–1000 m by late afternoon. Expect the top to stay in cloud for most or all of daylight, with no dependable break. Some rain is likely, with around 5-10 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: Summit wind could be roughly 21-62 mph, which changes how difficult exposed walking may feel.

Cloud-free timing: Best around midday at about 75%; around 0% early and 0% later.

A rough, clagged-in day on Gairich: summit wind broadly 15-40 mph, with gusts 45-55 mph during the evening (gale-force winds). Much calmer lower down - generally 0-10 mph in the valley, rising towards the tops. Cloud base around 400–700 m in the morning, then around 1800–2100 m around midday and 600–900 m by late afternoon. The top is likely to drift in and out of cloud, with the best chance of a view from midday into the afternoon. Cloud is likely to hang lowest on western slopes; the eastern 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 6 to 10°C, feeling around 0 to 4°C in the wind - wrap up. Low confidence (Summit wind could be roughly 21-62 mph, which changes how difficult exposed walking may feel) - the summit peak could be anywhere from 21 to 62 mph; check again nearer the time.
