Meall Horn weather forecast.

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

Cloud-free timing: Cloudy early, clearing later.

A mixed day on Meall Horn: summit wind broadly 15-30 mph, with gusts 30-40 mph during the morning (strong winds). Thunder watch from late afternoon into the evening: a small but credible risk is present. Watch for growing clouds and leave exposed tops if thunder develops. Much calmer lower down - generally 5-15 mph in the valley, rising towards the tops. Cloud base around 300–600 m in the morning, then around 900–1200 m around midday and 700–1000 m by late afternoon. Summit cloud should lift later, bringing a better chance of clear views. Little or no rain expected.

Forecast confidence: Rain is possible, but forecast models differ by about 6 hours on when it arrives.

A grey, cloudy day on Meall Horn: summit wind broadly 15-30 mph, with gusts 35-45 mph early in the morning (strong winds). Much calmer lower down - generally 5-15 mph in the valley, rising towards the tops. Cloud base mostly around 100–400 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 northeastern slopes; the southwestern 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. Confidence moderate (Summit wind could be roughly 18-35 mph, which changes how difficult exposed walking may feel) - the summit peak could reasonably be 18-35 mph, so treat the headline as mid-range.

Forecast confidence: Rain is possible, but forecast models differ by about 19 hours on when it arrives.

A grey, cloudy day on Meall Horn: summit wind broadly 10-20 mph, with gusts 15-25 mph during the evening (fresh and blowy). Cloud base around 100-400 m in the morning, lifting to 400-700 m around midday. Expect the top to stay in cloud for most or all of daylight, with no dependable break. Some rain is likely, with up to around 2 mm indicated; timing and local totals remain uncertain.

Forecast confidence: Rain is possible, but forecast models differ by about 14 hours on when it arrives.

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

A grey, cloudy day on Meall Horn: summit wind broadly 5-15 mph, with gusts 10-20 mph during the evening (a moderate breeze).

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

A grey, cloudy day on Meall Horn: summit wind broadly 10-25 mph, with gusts 20-30 mph during the morning (fresh and blowy). A meaningful thunderstorm risk is indicated from early morning into the evening. Avoid committing to exposed ridges if storms begin to build. There could be a spate risk based on forecast rainfall. Burns and unbridged crossings may rise quickly. Most likely from around 08:00 until around 03:00 the following day. Cloud base around 100–400 m in the morning, then around 300–600 m around midday and 100–400 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. Confidence moderate (Summit wind could be roughly 10-29 mph, which changes how difficult exposed walking may feel) - the summit peak could reasonably be 10-29 mph, so treat the headline as mid-range.

Forecast confidence: Summit wind could be roughly 23-43 mph, which changes how difficult exposed walking may feel.

A rough, clagged-in day on Meall Horn: summit wind broadly 25-35 mph, with gusts 40-50 mph during the morning (gale-force winds). The ground is likely to be wet after recent rain. Severe spate risk based on forecast rainfall. Burns and unbridged crossings may become unsafe or impassable. Most likely from around 00:00 until around 20:00. 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 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. 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. Confidence moderate (Summit wind could be roughly 23-43 mph, which changes how difficult exposed walking may feel) - the summit peak could reasonably be 23-43 mph, so treat the headline as mid-range.
