Chapelfell Top weather forecast.

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

Cloud-free timing: Cloudy early, clearing later.

A fine day on Chapelfell Top: summit wind broadly 10-20 mph, with gusts 20-30 mph during the morning (fresh and blowy). A meaningful thunderstorm risk is indicated from around midday into the evening. Avoid committing to exposed ridges if storms begin to build. Any cloud sits well above the tops (base 900-1600 m) - clear summits. Little or no rain expected.

A grey, cloudy day on Chapelfell Top: summit wind broadly 5-20 mph, with gusts 20-30 mph during the evening (fresh and blowy). A meaningful thunderstorm risk is indicated from the morning into the evening. Avoid committing to exposed ridges if storms begin to build. Cloud base mostly around 500–800 m through daylight. 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.

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

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

A rough, clagged-in day on Chapelfell Top: summit wind broadly 10-30 mph, with gusts 25-35 mph during the evening (strong winds). A meaningful thunderstorm risk is indicated from around midday 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. Much calmer lower down - generally 0-10 mph in the valley, rising towards the tops. Cloud base mostly around 500–800 m through daylight. Expect clag for much of the day, though a brief clearance is possible during the evening. 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 10-20 mm indicated; local totals could vary considerably. Confidence moderate (forecast models agree on the walking impact of the wind) - the summit peak could reasonably be 16-28 mph, so treat the headline as mid-range.

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

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

A mixed day on Chapelfell Top: summit wind broadly 5-25 mph, with gusts 25-35 mph early in the morning (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 900–1200 m around midday and 1300–1600 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 14-26 mph, which changes how difficult exposed walking may feel) - the summit peak could reasonably be 14-26 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 Chapelfell Top: summit wind broadly 10-30 mph, with gusts 30-40 mph early in the morning (strong winds). A meaningful thunderstorm risk is indicated from the morning into the evening. Avoid committing to exposed ridges if storms begin to build. The ground is likely to be wet after recent rain. Much calmer lower down - generally 5-15 mph in the valley, rising towards the tops. Any cloud sits well above the tops (base 900-1200 m) - clear summits. Some rain is likely, with up to around 2 mm indicated; timing and local totals remain uncertain. Confidence moderate (Summit wind could be roughly 21-34 mph, which changes how difficult exposed walking may feel) - the summit peak could reasonably be 21-34 mph, so treat the headline as mid-range.

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

Cloud-free timing: Cloudier around midday at about 25%; around 100% early and 100% later.

A mixed day on Chapelfell Top: summit wind broadly 15-35 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. The ground is likely to be wet after recent rain. Much calmer lower down - generally 5-15 mph in the valley, rising towards the tops. Cloud is likely to hang lowest on western slopes; the eastern 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 15-41 mph, which changes how difficult exposed walking may feel) - the summit peak could reasonably be 15-41 mph, so treat the headline as mid-range.
