The Roaches weather forecast.

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

A mixed day on The Roaches: summit wind broadly 10-25 mph, with gusts 25-35 mph early in the morning (strong winds). Thunderstorms are forecast from the morning into the evening. Avoid exposed summits and ridges during the risk period. Much calmer lower down - generally 5-15 mph in the valley, rising towards the tops. Any cloud sits well above the tops (base 500-3100 m) - clear summits. 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 67% early, falling to around 0% later.

A rough, clagged-in day on The Roaches: 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. Cloud base mostly around 500–800 m through daylight. The top is likely to drift in and out of cloud, with the best chance of a view during the morning. A persistently wet day is possible, with around 10-20 mm indicated; local totals could vary considerably. 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: Thunderstorm timing is inherently uncertain and may shift by several hours.

A grey, cloudy day on The Roaches: summit wind broadly 15-30 mph, with gusts 30-40 mph during the afternoon (strong winds). A meaningful thunderstorm risk is indicated from the morning into the evening. Avoid committing to exposed ridges if storms begin to build. 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 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 21-27 mph, so treat the headline as mid-range. Treat the cloud base with caution - the models disagree on humidity, so it could be well above or below the figure given.

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

A grey, cloudy day on The Roaches: summit wind broadly 10-25 mph, with gusts 20-30 mph during the morning (fresh and blowy). A meaningful thunderstorm risk is indicated from late afternoon into the evening. Avoid committing to exposed ridges if storms begin to build. 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 southern slopes; the northern 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.

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

Cloud-free timing: Cloudy early, clearing later.

A mixed day on The Roaches: summit wind broadly 10-25 mph, with gusts 20-30 mph early in the morning (fresh and blowy). Thunderstorms are a significant hazard from the morning into the evening. Exposed summits and ridges are a poor choice while storms are nearby. 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 02:00 the following day. 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 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 100% later.

A mixed day on The Roaches: summit wind broadly 20-35 mph, with gusts 40-50 mph during the afternoon (gale-force winds). A meaningful thunderstorm risk is indicated from early morning into the evening. 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 300–600 m in the morning, lifting to 400–700 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 from late afternoon 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 2-5 mm indicated; timing and local totals remain uncertain. Confidence moderate (Summit wind could be roughly 25-40 mph, which changes how difficult exposed walking may feel) - the summit peak could reasonably be 25-40 mph, so treat the headline as mid-range.
