Knock Fell weather forecast.

Forecast confidence: Rain is possible, but forecast models differ by about 4 hours on when it arrives.

Cloud-free timing: Best around midday at about 100%; around 33% early and 40% later.

A mixed day on Knock Fell: summit wind broadly 20-35 mph, with gusts 35-45 mph during the morning (gale-force winds). Cloud base around 700–1000 m in the morning, then around 900–1200 m around midday and 500–800 m by late afternoon. The top is likely to drift in and out of cloud, with the best chance of a view from the morning into the afternoon. Some rain is likely, with up to around 2 mm indicated; timing and local totals remain uncertain.

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

A grey, cloudy day on Knock Fell: summit wind broadly 15-30 mph, with gusts 30-40 mph during the evening (strong 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 saturated after recent rain. Expect boggy paths and rapid runoff if more rain arrives. Much calmer lower down - generally 5-15 mph in the valley, rising towards the tops. Cloud base mostly around 400–700 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 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 (forecast models agree on the walking impact of the wind) - the summit peak could reasonably be 17-28 mph, so treat the headline as mid-range.

A grey, cloudy day on Knock Fell: summit wind broadly 10-20 mph, with gusts 15-25 mph early in the morning (fresh and blowy). The ground is likely to be wet after recent rain. Cloud base mostly around 400–700 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 southwestern slopes; the northeastern 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.

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

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

A grey, cloudy day on Knock Fell: summit wind broadly 10-25 mph, with gusts 20-30 mph around midday (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. The ground is likely to be wet after recent rain. Cloud base around 400–700 m in the morning, lifting to 600–900 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 late afternoon into the evening. Cloud is likely to hang lowest on southwestern slopes; the northeastern 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.

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

A wild day on Knock Fell: summit wind broadly 35-50 mph, with gusts 60-70 mph during the afternoon (storm-force winds). Thunderstorms are possible from the morning into the afternoon. Keep an escape route from exposed ridges and descend if thunder develops. Much calmer lower down - generally 20-30 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. The top is likely to drift in and out of cloud, with the best chance of a view from around midday into the evening. 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 5-10 mm indicated; timing and local totals remain uncertain. Cold on top: air temperature broadly 6 to 10°C, feeling around 0 to 4°C in the wind - wrap up. Confidence moderate (Summit wind could be roughly 34-52 mph, which changes how difficult exposed walking may feel) - the summit peak could reasonably be 34-52 mph, so treat the headline as mid-range.

Forecast confidence: Rain is possible, but forecast models differ by about 12 hours on when it arrives.

A rough, clagged-in day on Knock Fell: summit wind broadly 30-45 mph, with gusts 50-60 mph around midday (storm-force winds).
