Haddington Hill weather forecast.

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

A mixed day on Haddington Hill: summit wind broadly 5-15 mph, with gusts 10-20 mph during the evening (a moderate breeze). Thunderstorms are forecast from early morning into the evening. Avoid exposed summits and ridges during the risk period. Any cloud sits well above the tops (base 500-2000 m) - clear summits. Some rain is likely, with around 2-5 mm indicated; timing and local totals remain uncertain.

A fine day on Haddington Hill: summit wind broadly 10-25 mph, with gusts 20-30 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. Any cloud sits well above the tops (base 500-1400 m) - clear summits. 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 67% early, improving to around 100% later.

A mixed day on Haddington Hill: summit wind broadly 15-25 mph, with gusts 25-35 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. Any cloud sits well above the tops (base 400-1000 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. Confidence moderate (forecast models agree on the walking impact of the wind) - the summit peak could reasonably be 20-25 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.

A mixed day on Haddington Hill: summit wind broadly 10-25 mph, with gusts 25-35 mph during the afternoon (fresh and blowy). A meaningful thunderstorm risk is indicated from around midday into the evening. Avoid committing to exposed ridges if storms begin to build. Any cloud sits well above the tops (base 400-900 m) - clear summits. 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 2-5 mm indicated; timing and local totals remain uncertain. Bright spells with UV up to 6 - sunscreen on exposed skin. Confidence moderate (forecast models agree on the walking impact of the wind) - the summit peak could reasonably be 16-27 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.

A fine day on Haddington Hill: summit wind broadly 10-20 mph, with gusts 20-30 mph during the evening (fresh and blowy). A meaningful thunderstorm risk is indicated from the morning into the evening. Avoid committing to exposed ridges if storms begin to build. Any cloud sits well above the tops (base 700-1500 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.

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

A mixed day on Haddington Hill: summit wind broadly 15-25 mph, with gusts 25-35 mph during the afternoon (fresh and blowy). Thunderstorms are possible from early morning into the evening. Keep an escape route from exposed ridges and descend if thunder develops. 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. Some rain is likely, with around 2-5 mm indicated; timing and local totals remain uncertain.
