Streap weather forecast.

Cloud-free timing: Cloudy early, clearing later.

A fine day on Streap: summit wind broadly 10-25 mph, with gusts 25-35 mph during the afternoon (fresh and blowy). Much calmer lower down - generally 0-10 mph in the valley, rising towards the tops. Any cloud sits well above the tops (base 1000-1500 m) - clear summits. Little or no rain expected.

Cloud-free timing: Cloudy early, clearing later.

A mixed day on Streap: summit wind broadly 20-30 mph, with gusts 30-40 mph during the evening (strong winds). Much calmer lower down - generally 5-15 mph in the valley, rising towards the tops. Little or no rain expected. Confidence moderate (forecast models agree on the walking impact of the wind) - the summit peak could reasonably be 21-27 mph, so treat the headline as mid-range.

Forecast confidence: Rain is possible, but forecast models differ by about 17 hours on when it arrives.

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

A mixed day on Streap: summit wind broadly 5-30 mph, with gusts 35-45 mph early in the morning (strong winds). Thunder watch from late afternoon into the evening: a small but credible risk is present. Watch for growing clouds and leave exposed tops if thunder develops. Much calmer lower down - generally 0-10 mph in the valley, rising towards the tops. Any cloud sits well above the tops (base 1000-1500 m) - clear summits. Little or no rain expected. Confidence moderate (Summit wind could be roughly 17-32 mph, which changes how difficult exposed walking may feel) - the summit peak could reasonably be 17-32 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 40% later.

A grey, cloudy day on Streap: summit wind broadly 5-25 mph, with gusts 20-30 mph during the evening (fresh and blowy). Thunderstorms are possible from around midday into the evening. Keep an escape route from exposed ridges and descend if thunder develops. Cloud base around 400-700 m in the morning, lifting to 600-900 m around midday. The top is likely to drift in and out of cloud, with the best chance of a view during the afternoon. Little or no rain expected.

Forecast confidence: Rain is possible, but forecast models differ by about 14 hours on when it arrives.

A grey, cloudy day on Streap: summit wind broadly 0-15 mph, with gusts 10-20 mph early in the morning (a moderate breeze). Cloud base around 400–700 m in the morning, lifting to 900–1200 m around midday and 800–1100 m by late afternoon. Expect the top to stay in cloud for most or all of daylight, with no dependable break. Some rain is likely, with up to around 2 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 40% later.

A grey, cloudy day on Streap: summit wind broadly 5-15 mph, with gusts 10-20 mph during the afternoon (a moderate breeze). A meaningful thunderstorm risk is indicated from early morning into the evening. Avoid committing to exposed ridges if storms begin to build. Cloud base around 400-700 m in the morning, lifting to 800-1100 m around midday. Expect clag for much of the day, though a brief clearance is possible during the evening. Some rain is likely, with around 2-5 mm indicated; timing and local totals remain uncertain. 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: Summit wind could be roughly 19-58 mph, which changes how difficult exposed walking may feel.

Cloud-free timing: Around 0% early, improving to around 20% later.

A rough, clagged-in day on Streap: summit wind broadly 15-40 mph, with gusts 40-50 mph during the evening (gale-force winds). 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 900–1200 m around midday and 600–900 m by late afternoon. Expect clag for much of the day, though a brief clearance is possible during the afternoon. 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. Cold on top: air temperature broadly 6 to 10°C, feeling around 0 to 4°C in the wind - wrap up. Low confidence (Summit wind could be roughly 19-58 mph, which changes how difficult exposed walking may feel) - the summit peak could be anywhere from 19 to 58 mph; check again nearer the time.
