Cnoc Coinnich weather forecast.

Cloud-free timing: Cloudy early, clearing later.

A mixed day on Cnoc Coinnich: summit wind broadly 20-35 mph, with gusts 35-45 mph early in the morning (gale-force winds). Thunderstorms are possible from late afternoon 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 500–800 m in the morning, then around 1000–1300 m around midday and 700–1000 m by late afternoon. Summit cloud should lift later, bringing a better chance of clear views. 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.

Forecast confidence: Summit wind could be roughly 13-29 mph, which changes how difficult exposed walking may feel.

Cloud-free timing: Around 0% early, improving to around 60% later.

A mixed day on Cnoc Coinnich: summit wind broadly 10-25 mph, with gusts 25-35 mph early in the morning (fresh and blowy). 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 900–1200 m around midday and 1400–1700 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. Little or no rain expected. Confidence moderate (Summit wind could be roughly 13-29 mph, which changes how difficult exposed walking may feel) - the summit peak could reasonably be 13-29 mph, so treat the headline as mid-range.

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

Cloud-free timing: Cloudy early, clearing later.

A mixed day on Cnoc Coinnich: summit wind broadly 10-25 mph, with gusts 25-35 mph during the evening (fresh and blowy). Thunderstorms are possible from the morning 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 900–1200 m around midday and 1300–1600 m by late afternoon. Summit cloud should lift later, bringing a better chance of clear views. Cloud is likely to hang lowest on northwestern slopes; the southeastern side should see somewhat higher bases and better breaks. Little or no rain expected. Bright spells with UV up to 5 - sunscreen on exposed skin. Confidence moderate (Summit wind could be roughly 15-26 mph, which changes how difficult exposed walking may feel) - the summit peak could reasonably be 15-26 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: A low thunderstorm risk remains difficult to time precisely.

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

A mixed day on Cnoc Coinnich: summit wind broadly 0-15 mph, with gusts 10-20 mph during the evening (a moderate breeze). Thunderstorms are possible from late afternoon into the evening.
