Grey Crag weather forecast.

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

Cloud-free timing: Around 100% early, falling to around 60% later.

A mixed day on Grey Crag: summit wind broadly 15-35 mph, with gusts 35-45 mph during the morning (strong winds). Thunderstorms are possible from around midday into the evening. Keep an escape route from exposed ridges and descend if thunder develops. Much calmer lower down - generally 5-15 mph in the valley, rising towards the tops. Any cloud sits well above the tops (base 700-1000 m) - clear summits. 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 20% later.

A grey, cloudy day on Grey Crag: summit wind broadly 15-25 mph, with gusts 25-35 mph around midday (strong winds). A meaningful thunderstorm risk is indicated from early morning into the afternoon. 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 base mostly around 400–700 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 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 16-28 mph, so treat the headline as mid-range.

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

A grey, cloudy day on Grey Crag: summit wind broadly 5-20 mph, with gusts 15-25 mph around midday (a moderate breeze). Thunderstorms are possible from early morning into the afternoon. Keep an escape route from exposed ridges and descend if thunder develops. 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: Cloudy early, clearing later.

A mixed day on Grey Crag: summit wind broadly 10-25 mph, with gusts 20-30 mph around midday (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. There could be a spate risk based on forecast rainfall. Burns and unbridged crossings may rise quickly. Most likely from around 05:00 until around 03:00 the following day. Cloud base around 300–600 m in the morning, lifting to 600–900 m around midday and 900–1200 m by late afternoon. Summit cloud should lift later, bringing a better chance of clear views. 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.

Cloud-free timing: Cloudy early, clearing later.

A wild day on Grey Crag: summit wind broadly 30-45 mph, with gusts 50-60 mph during the afternoon (storm-force winds). Thunderstorms are possible from the morning into the evening. Keep an escape route from exposed ridges and descend if thunder develops. Much calmer lower down - generally 15-25 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 1300–1600 m by late afternoon. 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 5-10 mm indicated; timing and local totals remain uncertain. Confidence moderate (Summit wind could be roughly 30-49 mph, which changes how difficult exposed walking may feel) - the summit peak could reasonably be 30-49 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.

Cloud-free timing: Around 100% early, falling to around 0% later.

A wild day on Grey Crag: summit wind broadly 25-40 mph, with gusts 45-55 mph around midday (gale-force winds). The ground is likely to be wet after recent rain. Much calmer lower down - generally 10-20 mph in the valley, rising towards the tops. Cloud base around 0–300 m in the morning, then around 700–1000 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 early morning into around midday. 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 up to around 2 mm indicated; timing and local totals remain uncertain. Cold on top: air temperature broadly 4 to 8°C, feeling around 0 to 4°C in the wind - wrap up. Confidence moderate (Summit wind could be roughly 28-41 mph, which changes how difficult exposed walking may feel) - the summit peak could reasonably be 28-41 mph, so treat the headline as mid-range.
