Armboth Fell weather forecast.

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

A fine day on Armboth Fell: summit wind broadly 5-20 mph, with gusts 15-25 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 700-1500 m) - clear summits. Cloud is likely to hang lowest on eastern slopes; the western side should see somewhat higher bases and better breaks. Little or no rain expected.

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

Cloud-free timing: Around 100% early, falling to around 80% later.

A wild day on Armboth Fell: summit wind broadly 5-20 mph, with gusts 15-25 mph early in the morning (a moderate breeze). 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 400-700 m) - clear summits. A persistently wet day is possible, with around 5-10 mm indicated; local totals could vary considerably.

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

A rough, clagged-in day on Armboth Fell: summit wind broadly 5-25 mph, with gusts 20-30 mph during the evening (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. 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 20:00. Cloud base around 300–600 m in the morning, lifting to 400–700 m around midday and 600–900 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. A persistently wet day is possible, with around 5-10 mm indicated; local totals could vary considerably. Confidence moderate (Summit wind could be roughly 12-25 mph, which changes how difficult exposed walking may feel) - the summit peak could reasonably be 12-25 mph, so treat the headline as mid-range.

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

Cloud-free timing: Best around midday at about 100%; around 0% early and 0% later.

A mixed day on Armboth Fell: summit wind broadly 0-15 mph, with gusts 10-20 mph during the morning (a moderate breeze). The ground is likely to be wet after recent rain. Cloud base around 400–700 m in the morning, then around 600–900 m around midday and 400–700 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 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 33% early, improving to around 60% later.

A mixed day on Armboth Fell: summit wind broadly 10-20 mph, with gusts 15-25 mph during the afternoon (fresh and blowy). Thunderstorms are a significant hazard from early morning into the evening. Exposed summits and ridges are a poor choice while storms are nearby. 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 900–1200 m by late afternoon. The top is likely to drift in and out of cloud; views may come and go. 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: Cloudy early, clearing later.

A mixed day on Armboth Fell: summit wind broadly 15-30 mph, with gusts 30-40 mph during the afternoon (strong winds). Thunderstorms are a significant hazard from early morning into the evening. Exposed summits and ridges are a poor choice while storms are nearby. 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. Summit cloud should lift later, bringing a better chance of clear views. 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. Low confidence (Summit wind could be roughly 14-36 mph, which changes how difficult exposed walking may feel) - the summit peak could be anywhere from 14 to 36 mph; check again nearer the time.
