Hallin Fell weather forecast.

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

A mixed day on Hallin Fell: summit wind broadly 5-20 mph, with gusts 15-25 mph around midday (a moderate breeze). Thunderstorms are possible from around midday into the evening. Keep an escape route from exposed ridges and descend if thunder develops. Any cloud sits well above the tops (base 500-800 m) - clear summits. 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 fine day on Hallin Fell: 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. The ground is likely to be wet after recent rain. Any cloud sits well above the tops (base 400-700 m) - clear summits. Cloud is likely to hang lowest on western slopes; the eastern side should see somewhat higher bases and better breaks. Little or no rain expected.

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

A fine day on Hallin Fell: summit wind broadly 5-15 mph, with gusts 10-20 mph during the afternoon (a moderate breeze). Thunderstorms are possible from early morning into the afternoon. Keep an escape route from exposed ridges and descend if thunder develops. Any cloud sits well above the tops (base 400-700 m) - clear summits. Cloud is likely to hang lowest on southwestern slopes; the northeastern side should see somewhat higher bases and better breaks. Little or no rain expected.

Avoid committing to exposed ridges if storms begin to build. Any cloud sits well above the tops (base 400-800 m) - clear summits.

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

A mixed day on Hallin Fell: summit wind broadly 20-35 mph, with gusts 35-45 mph during the afternoon (gale-force winds). Thunderstorms are possible from early morning into the afternoon. Keep an escape route from exposed ridges and descend if thunder develops. Any cloud sits well above the tops (base 900-2900 m) - clear summits. 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 23-37 mph, which changes how difficult exposed walking may feel) - the summit peak could reasonably be 23-37 mph, so treat the headline as mid-range.

Forecast confidence: Rain is possible, but forecast models differ by about 13 hours on when it arrives.

A mixed day on Hallin Fell: summit wind broadly 15-30 mph, with gusts 30-40 mph around midday (strong winds). Any cloud sits well above the tops (base 600-1500 m) - clear summits. 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 19-27 mph, so treat the headline as mid-range.
