Cribyn weather forecast.

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

A mixed day on Cribyn: summit wind broadly 5-20 mph, with gusts 20-30 mph early in the morning (fresh and blowy). Thunder watch from the morning into the evening: a small but credible risk is present. Watch for growing clouds and leave exposed tops if thunder develops. Cloud base around 500–800 m in the morning, lifting to 700–1000 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 late afternoon into the evening. Cloud is likely to hang lowest on southeastern slopes; the northwestern side should see somewhat higher bases and better breaks. Little or no rain expected. Cloud base is the least certain part of this - the models are only moderately agreed, so it could sit a couple of hundred metres either way.

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

Cloud-free timing: Around 0% early, improving to around 40% later.

A grey, cloudy day on Cribyn: summit wind broadly 10-25 mph, with gusts 25-35 mph during the afternoon (fresh and blowy). Thunderstorms are forecast from early morning into the evening. Avoid exposed summits and ridges during the risk period. Much calmer lower down - generally 0-10 mph in the valley, rising towards the tops. Cloud base around 400–700 m through the morning, lifting to 700–1000 m by late afternoon. Expect clag for much of the day, though a brief clearance is possible during the evening. 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 5-10 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 Cribyn: summit wind broadly 10-30 mph, with gusts 30-40 mph during the evening (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. Much calmer lower down - generally 5-15 mph in the valley, rising towards the tops. Cloud base around 400–700 m through the morning, lifting to 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 up to around 2 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 22-29 mph, so treat the headline as mid-range.

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

A rough, clagged-in day on Cribyn: summit wind broadly 20-40 mph, with gusts 40-50 mph during the afternoon (gale-force winds). A meaningful thunderstorm risk is indicated from the morning into the afternoon. Avoid committing to exposed ridges if storms begin to build. Much calmer lower down - generally 10-20 mph in the valley, rising towards the tops. Cloud base around 400–700 m through the morning, lifting to 700–1000 m by late afternoon. 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. Low confidence (Summit wind could be roughly 23-48 mph, which changes how difficult exposed walking may feel) - the summit peak could be anywhere from 23 to 48 mph; check again nearer the time.

Cloud-free timing: Around 0% early, improving to around 40% later.

A wild day on Cribyn: summit wind broadly 20-40 mph, with gusts 40-50 mph during the evening (gale-force winds). A meaningful thunderstorm risk is indicated from the morning into the evening. 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 around 400–700 m in the morning, then around 1400–1700 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 the morning into 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 30-38 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: Cloudy early, clearing later.

A wild day on Cribyn: summit wind broadly 30-45 mph, with gusts 55-65 mph early in the morning (storm-force winds). Much calmer lower down - generally 15-25 mph in the valley, rising towards the tops. Any cloud sits well above the tops (base 900-1500 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. Cold on top: air temperature broadly 6 to 10°C, feeling around 0 to 4°C in the wind - wrap up. Confidence moderate (forecast models agree on the walking impact of the wind) - the summit peak could reasonably be 36-48 mph, so treat the headline as mid-range. Cloud base is the least certain part of this - the models are only moderately agreed, so it could sit a couple of hundred metres either way.

Forecast confidence: Rain is possible, but forecast models differ by about 12 hours on when it arrives.

Cloud-free timing: Cloudy early, clearing later.
