Grike weather forecast.

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

A mixed day on Grike: summit wind broadly 15-30 mph, with gusts 30-40 mph early in the morning (strong winds). Thunderstorms are a significant hazard from the morning into the evening. Exposed summits and ridges are a poor choice while storms are nearby. Much calmer lower down - generally 5-15 mph in the valley, rising towards the tops. Any cloud sits well above the tops (base 1900-3100 m) - clear summits. 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 20-31 mph, so treat the headline as mid-range.

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

Cloud-free timing: Around 67% early, improving to around 100% later.

A mixed day on Grike: summit wind broadly 15-30 mph, with gusts 30-40 mph early in the morning (strong winds). Thunderstorms are a significant hazard from around midday into the evening. Exposed summits and ridges are a poor choice while storms are nearby. Much calmer lower down - generally 5-15 mph in the valley, rising towards the tops. Any cloud sits well above the tops (base 700-1500 m) - clear summits. 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 21-25 mph, so treat the headline as mid-range.

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

A grey, cloudy day on Grike: 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 around midday. Avoid committing to exposed ridges if storms begin to build. 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 20-28 mph, so treat the headline as mid-range.

Forecast confidence: Rain is possible, but forecast models differ by about 9 hours on when it arrives.

A grey, cloudy day on Grike: summit wind broadly 5-20 mph, with gusts 15-25 mph during the afternoon (fresh and blowy). 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 Grike: 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. Cloud base around 400–700 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 southern slopes; the northern 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 16-27 mph, so treat the headline as mid-range.

Forecast confidence: Forecast models disagree on whether meaningful rain reaches the hills during 10:00-16:00.

Cloud-free timing: Cloudy early, clearing later.

A wild day on Grike: summit wind broadly 35-50 mph, with gusts 55-65 mph during the afternoon (storm-force winds). 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 23:00. 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. A persistently wet day is possible, with around 10-20 mm indicated; local totals could vary considerably. Confidence moderate (Summit wind could be roughly 34-51 mph, which changes how difficult exposed walking may feel) - the summit peak could reasonably be 34-51 mph, so treat the headline as mid-range.

Forecast confidence: Summit wind could be roughly 34-50 mph, which changes how difficult exposed walking may feel.

A wild day on Grike: 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. There could be a spate risk based on forecast rainfall. Burns and unbridged crossings may rise quickly. Most likely from around 08:00 until around 03:00 the following day. Much calmer lower down - generally 10-20 mph in the valley, rising towards the tops. Any cloud sits well above the tops (base 500-800 m) - clear summits. Cloud is likely to hang lowest on western slopes; the eastern side should see somewhat higher bases and better breaks. A persistently wet day is possible, with around 10-20 mm indicated; local totals could vary considerably. Confidence moderate (Summit wind could be roughly 34-50 mph, which changes how difficult exposed walking may feel) - the summit peak could reasonably be 34-50 mph, so treat the headline as mid-range.
