Gray 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 Gray Crag: summit wind broadly 20-35 mph, with gusts 40-50 mph during the morning (gale-force 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.

A grey, cloudy day on Gray Crag: summit wind broadly 15-30 mph, with gusts 30-40 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 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 (Summit wind could be roughly 18-31 mph, which changes how difficult exposed walking may feel) - the summit peak could reasonably be 18-31 mph, so treat the headline as mid-range.

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

A grey, cloudy day on Gray Crag: summit wind broadly 10-20 mph, with gusts 20-30 mph early in the morning (fresh and blowy). 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: Around 0% early, improving to around 60% later.

A grey, cloudy day on Gray Crag: summit wind broadly 15-25 mph, with gusts 25-35 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. The top is likely to drift in and out of cloud, with the best chance of a view during the afternoon. 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. Confidence moderate (forecast models agree on the walking impact of the wind) - the summit peak could reasonably be 17-26 mph, so treat the headline as mid-range.

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

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

A wild day on Gray Crag: 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 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. 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. Low confidence (Summit wind could be roughly 34-56 mph, which changes how difficult exposed walking may feel) - the summit peak could be anywhere from 34 to 56 mph; check again nearer the time.

Forecast confidence: Summit wind could be roughly 32-46 mph, which changes how difficult exposed walking may feel.

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

A wild day on Gray Crag: summit wind broadly 30-45 mph, with gusts 50-60 mph around midday (storm-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 -2 to 2°C in the wind - wrap up. Confidence moderate (Summit wind could be roughly 32-46 mph, which changes how difficult exposed walking may feel) - the summit peak could reasonably be 32-46 mph, so treat the headline as mid-range.
