Tolmount weather forecast.

Cloud-free timing: Around 0% early, improving to around 20% later.

A grey, cloudy day on Tolmount: summit wind broadly 10-25 mph, with gusts 25-35 mph around midday (fresh and blowy). Cloud base around 500-800 m in the morning, lifting to 800-1100 m around midday. The top is likely to drift in and out of cloud, with the best chance of a view during the afternoon. Cloud is likely to hang lowest on southeastern slopes; the northwestern side should see somewhat higher bases and better breaks. Little or no rain expected.

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

A mixed day on Tolmount: summit wind broadly 15-30 mph, with gusts 30-40 mph during the evening (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, then around 1300–1600 m around midday and 1100–1400 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 (forecast models agree on the walking impact of the wind) - the summit peak could reasonably be 22-27 mph, so treat the headline as mid-range.

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

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

A grey, cloudy day on Tolmount: summit wind broadly 5-20 mph, with gusts 15-25 mph early in the morning (a moderate breeze). Thunderstorms are possible from the morning into the evening. Keep an escape route from exposed ridges and descend if thunder develops. Cloud base around 500–800 m in the morning, lifting to 700–1000 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. Little or no rain expected.

Forecast confidence: Summit wind could be roughly 18-37 mph, which changes how difficult exposed walking may feel.

A grey, cloudy day on Tolmount: summit wind broadly 15-30 mph, with gusts 30-40 mph during the evening (strong winds). 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. 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. Little or no rain expected. Confidence moderate (Summit wind could be roughly 18-37 mph, which changes how difficult exposed walking may feel) - the summit peak could reasonably be 18-37 mph, so treat the headline as mid-range.

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

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

A grey, cloudy day on Tolmount: summit wind broadly 5-25 mph, with gusts 25-35 mph early in the morning (strong 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 0-10 mph in the valley, rising towards the tops. Cloud base around 600–900 m in the morning, then around 1300–1600 m around midday and 800–1100 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. Some rain is likely, with up to around 2 mm indicated; timing and local totals remain uncertain. Confidence moderate (Summit wind could be roughly 15-34 mph, which changes how difficult exposed walking may feel) - the summit peak could reasonably be 15-34 mph, so treat the headline as mid-range.

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

A rough, clagged-in day on Tolmount: summit wind broadly 0-15 mph, with gusts 5-15 mph during the evening (a moderate breeze). A meaningful thunderstorm risk is indicated from the 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 00:00 until around 23:00. Cloud base around 400–700 m in the morning, then around 800–1100 m around midday and 500–800 m by late afternoon. Expect the top to stay in cloud for most or all of daylight, with no dependable break. A persistently wet day is possible, with around 10-20 mm indicated; local totals could vary considerably. 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: Forecast models disagree on whether meaningful rain reaches the hills during 10:00-16:00.

Cloud-free timing: Around 0% early, improving to around 20% later.

A grey, cloudy day on Tolmount: summit wind broadly 5-30 mph, with gusts 30-40 mph during the evening (strong winds). The ground is likely to be wet after recent rain. Much calmer lower down - generally 0-10 mph in the valley, rising towards the tops. Cloud base around 400–700 m in the morning, lifting to 800–1100 m around midday and 900–1200 m by late afternoon. Expect clag for much of the day, though a brief clearance is possible during the afternoon. Some rain is likely, with around 5-10 mm indicated; timing and local totals remain uncertain. Confidence moderate (Summit wind could be roughly 16-38 mph, which changes how difficult exposed walking may feel) - the summit peak could reasonably be 16-38 mph, so treat the headline as mid-range.
