Meall a' Bhuachaille weather forecast.

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

Cloud-free timing: Around 100% early, falling to around 60% later.

A mixed day on Meall a' Bhuachaille: summit wind broadly 10-30 mph, with gusts 30-40 mph during the afternoon (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 700-1500 m) - clear summits. Little or no rain expected.

A grey, cloudy day on Meall a' Bhuachaille: summit wind broadly 5-20 mph, with gusts 15-25 mph during the afternoon (fresh and blowy). 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. Cloud is likely to hang lowest on northern slopes; the southern side should see somewhat higher bases and better breaks. Some rain is likely, with around 5-10 mm indicated; timing and local totals remain uncertain.

Forecast confidence: Rain is possible, but forecast models differ by about 10 hours on when it arrives.

Cloud-free timing: Cloudy early, clearing later.

A mixed day on Meall a' Bhuachaille: summit wind broadly 5-15 mph, with gusts 10-20 mph early in the morning (a moderate breeze). Cloud base around 400–700 m in the morning, lifting to 1100–1400 m around midday and 1300–1600 m by late afternoon. Summit cloud should lift later, bringing a better chance of clear views. Little or no rain expected.

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

Cloud-free timing: Cloudy early, clearing later.

A mixed day on Meall a' Bhuachaille: summit wind broadly 5-20 mph, with gusts 15-25 mph during the evening (a moderate breeze). Thunderstorms are a significant hazard from the morning into the evening. Exposed summits and ridges are a poor choice while storms are nearby. Cloud base around 400–700 m in the morning, lifting to 800–1100 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 southern slopes; the northern 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. 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.

A mixed day on Meall a' Bhuachaille: summit wind broadly 5-30 mph, with gusts 30-40 mph during the evening (strong 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. Any cloud sits well above the tops (base 800-1300 m) - clear summits. Some rain is likely, with around 5-10 mm indicated; timing and local totals remain uncertain. Low confidence (Summit wind could be roughly 14-39 mph, which changes how difficult exposed walking may feel) - the summit peak could be anywhere from 14 to 39 mph; check again nearer the time. 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 29-47 mph, which changes how difficult exposed walking may feel.

Cloud-free timing: Clear early, clouding up later.

A rough, clagged-in day on Meall a' Bhuachaille: summit wind broadly 30-45 mph, with gusts 50-60 mph during the morning (gale-force winds). Much calmer lower down - generally 10-20 mph in the valley, rising towards the tops. Cloud base around 1300–1600 m in the morning, lowering to 400–700 m around midday and 500–800 m by late afternoon. The summit should be clear early, with cloud building around midday. Cloud is likely to hang lowest on northwestern slopes; the southeastern 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. Cold on top: air temperature broadly 4 to 8°C, feeling around -4 to 0°C in the wind - wrap up. Confidence moderate (Summit wind could be roughly 29-47 mph, which changes how difficult exposed walking may feel) - the summit peak could reasonably be 29-47 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.
