Creag Mac Ranaich weather forecast.

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

A grey, cloudy day on Creag Mac Ranaich: summit wind broadly 15-35 mph, with gusts 35-45 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 600–900 m through daylight. 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 eastern slopes; the western side should see somewhat higher bases and better breaks. Little or no rain expected. Confidence moderate (forecast models agree on the walking impact of the wind) - the summit peak could reasonably be 24-32 mph, so treat the headline as mid-range.

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

A mixed day on Creag Mac Ranaich: summit wind broadly 20-35 mph, with gusts 35-45 mph during the evening (gale-force winds). Much calmer lower down - generally 10-20 mph in the valley, rising towards the tops. Cloud base around 600–900 m in the morning, lifting to 500–800 m around midday and 1200–1500 m by late afternoon. The top is likely to drift in and out of cloud, with the best chance of a view from around midday into the evening. Cloud is likely to hang lowest on eastern slopes; the western side should see somewhat higher bases and better breaks. Little or no rain expected.

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

A mixed day on Creag Mac Ranaich: summit wind broadly 10-30 mph, with gusts 25-35 mph early in the morning (strong winds). Much calmer lower down - generally 5-15 mph in the valley, rising towards the tops. Cloud base around 600–900 m in the morning, lifting to 700–1000 m around midday and 1200–1500 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. Confidence moderate (forecast models agree on the walking impact of the wind) - the summit peak could reasonably be 15-30 mph, so treat the headline as mid-range.

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

Cloud-free timing: Cloudy early, clearing later.

A mixed day on Creag Mac Ranaich: summit wind broadly 5-20 mph, with gusts 15-25 mph during the evening (a moderate breeze). A meaningful thunderstorm risk is indicated from late afternoon into the evening. Avoid committing to exposed ridges if storms begin to build. Cloud base around 400-700 m in the morning, lifting to 1300-1600 m around midday. Summit cloud should lift later, bringing a better chance of clear views. Little or no rain expected.

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

Cloud-free timing: Cloudy early, clearing later.

A fine day on Creag Mac Ranaich: summit wind broadly 0-15 mph, with gusts 10-20 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, lifting to 1300-1600 m around midday. Summit cloud should lift later, bringing a better chance of clear views. 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.

Some rain is likely, with around 2-5 mm indicated; timing and local totals remain uncertain.

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

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

A mixed day on Creag Mac Ranaich: summit wind broadly 10-35 mph, with gusts 35-45 mph during the evening (gale-force winds). A meaningful thunderstorm risk is indicated from early morning into the evening. Avoid committing to exposed ridges if storms begin to build. Much calmer lower down - generally 5-15 mph in the valley, rising towards the tops. Cloud base around 400–700 m in the morning, lifting to 600–900 m around midday and 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. Some rain is likely, with around 5-10 mm indicated; timing and local totals remain uncertain. Low confidence (Summit wind could be roughly 17-53 mph, which changes how difficult exposed walking may feel) - the summit peak could be anywhere from 17 to 53 mph; check again nearer the time.
