Coombe Hill 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 wild day on Coombe Hill: summit wind broadly 5-15 mph, with gusts 15-25 mph early in the morning (a moderate breeze). Thunderstorms are forecast from early morning into the evening. Avoid exposed summits and ridges during the risk period. There could be a spate risk based on forecast rainfall. Burns and unbridged crossings may rise quickly. Most likely from around 06:00 until around 16:00. Any cloud sits well above the tops (base 500-1100 m) - clear summits. A persistently wet day is possible, with around 5-10 mm indicated; local totals could vary considerably.

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

A mixed day on Coombe Hill: summit wind broadly 15-25 mph, with gusts 25-35 mph around midday (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. The ground is likely to be saturated after recent rain. Expect boggy paths and rapid runoff if more rain arrives. Any cloud sits well above the tops (base 600-900 m) - clear summits. 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.

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

A mixed day on Coombe Hill: summit wind broadly 10-20 mph, with gusts 20-30 mph around midday (fresh and blowy). Thunderstorms are a significant hazard from around midday 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. Any cloud sits well above the tops (base 400-700 m) - clear summits. 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.

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

A fine day on Coombe Hill: summit wind broadly 10-20 mph, with gusts 15-25 mph during the afternoon (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. The ground is likely to be wet after recent rain. Any cloud sits well above the tops (base 500-1000 m) - clear summits. Cloud is likely to hang lowest on southwestern slopes; the northeastern side should see somewhat higher bases and better breaks. Little or no rain expected. Bright spells with UV up to 5 - sunscreen on exposed skin.

Forecast confidence: The broad weather pattern is useful, although some detail may change.

A mixed day on Coombe Hill: summit wind broadly 20-30 mph, with gusts 35-45 mph around midday (strong winds). Any cloud sits well above the tops (base 700-1900 m) - clear summits. Little or no rain expected. Confidence moderate (forecast models agree on the walking impact of the wind) - the summit peak could reasonably be 22-32 mph, so treat the headline as mid-range.

Forecast confidence: A low thunderstorm risk remains difficult to time precisely.

A mixed day on Coombe Hill: summit wind broadly 15-25 mph, with gusts 25-35 mph around midday (fresh and blowy). Thunderstorms are possible from early morning into the afternoon. Keep an escape route from exposed ridges and descend if thunder develops. 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. 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 16-25 mph, so treat the headline as mid-range.
