Moel Druman weather forecast.

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 Moel Druman: 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. Cloud is likely to hang lowest on southeastern slopes; the northwestern 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.

A rough, clagged-in day on Moel Druman: summit wind broadly 10-25 mph, with gusts 25-35 mph during the morning (strong winds). A meaningful thunderstorm risk is indicated from late afternoon into the evening. Avoid committing to exposed ridges if storms begin to build. High spate risk based on forecast rainfall. Burns and unbridged crossings may become difficult or impassable. Most likely from around 07:00 until around 23:00. 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. A persistently wet day is possible, with around 20-40 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 18-26 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 0% early, improving to around 40% later.

A grey, cloudy day on Moel Druman: summit wind broadly 10-25 mph, with gusts 25-35 mph during the evening (strong winds). Thunderstorms are a significant hazard from early morning into the afternoon. Exposed summits and ridges are a poor choice while storms are nearby. 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 clag for much of the day, though a brief clearance is possible 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.

Forecast confidence: Rain is possible, but forecast models differ by about 5 hours on when it arrives.

A grey, cloudy day on Moel Druman: summit wind broadly 15-30 mph, with gusts 25-35 mph during the evening (strong winds). 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 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 (Summit wind could be roughly 17-34 mph, which changes how difficult exposed walking may feel) - the summit peak could reasonably be 17-34 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 0% early, improving to around 40% later.

A mixed day on Moel Druman: summit wind broadly 20-35 mph, with gusts 40-50 mph during the evening (gale-force winds). Thunderstorms are a significant hazard from the 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 00:00 until around 03:00 the following day. 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. The top is likely to drift in and out of cloud, with the best chance of a view from midday 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 5-10 mm indicated; timing and local totals remain uncertain. Confidence moderate (Summit wind could be roughly 19-37 mph, which changes how difficult exposed walking may feel) - the summit peak could reasonably be 19-37 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 Moel Druman: summit wind broadly 30-45 mph, with gusts 50-60 mph early in the morning (storm-force winds). The ground is likely to be wet after recent rain. Much calmer lower down - generally 15-25 mph in the valley, rising towards the tops. Any cloud sits well above the tops (base 600-1600 m) - clear summits. 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 33-49 mph, which changes how difficult exposed walking may feel) - the summit peak could reasonably be 33-49 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 14 hours on when it arrives.

Cloud-free timing: Cloudy early, clearing later.

A mixed day on Moel Druman: summit wind broadly 15-30 mph, with gusts 30-40 mph during the afternoon (strong winds). Any cloud sits well above the tops (base 900-1800 m) - clear summits. 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. Confidence moderate (forecast models agree on the walking impact of the wind) - the summit peak could reasonably be 20-29 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.
