400 m summit forecast for wind, cloud, rain and temperature. Updated from the Thursday 6 August 2026 model run.
Conditions can change quickly with height. Use the day-by-day summit detail below, then check again close to departure.
A mixed day on Rough Tor: summit wind broadly 5-20 mph, with gusts 15-25 mph during the morning (a moderate breeze). Any cloud sits well above the tops (base 1000-1400 m) - clear summits. Some rain is likely, with up to around 2 mm indicated; timing and local totals remain uncertain.
A fine day on Rough Tor: summit wind broadly 0-15 mph, with gusts 10-20 mph during the evening (a moderate breeze). Any cloud sits well above the tops (base 1200-1600 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.
A fine day on Rough Tor: summit wind broadly 5-15 mph, with gusts 10-20 mph during the morning (a moderate breeze). Any cloud sits well above the tops (base 1300-1900 m) - clear summits. Little or no rain expected. Bright spells with UV up to 6 - sunscreen on exposed skin. Low confidence (ensemble members are widely spread) - the summit peak could be anywhere from 7 to 17 mph; check again nearer the time. Treat the cloud base with caution - the models disagree on humidity, so it could be well above or below the figure given.
A fine day on Rough Tor: summit wind broadly 5-20 mph, with gusts 15-25 mph during the afternoon (a moderate breeze). Any cloud sits well above the tops (base 400-700 m) - clear summits. Little or no rain expected. Bright spells with UV up to 6 - sunscreen on exposed skin. Low confidence (ensemble members are widely spread) - the summit peak could be anywhere from 10 to 21 mph; check again nearer the time. Treat the cloud base with caution - the models disagree on humidity, so it could be well above or below the figure given.
A fine day on Rough Tor: summit wind broadly 5-15 mph, with gusts 10-20 mph during the afternoon (a moderate breeze). Any cloud sits well above the tops (base 600-1400 m) - clear summits. Little or no rain expected. Bright spells with UV up to 6 - sunscreen on exposed skin. Low confidence (ensemble members are widely spread) - the summit peak could be anywhere from 5 to 17 mph; check again nearer the time. Treat the cloud base with caution - the models disagree on humidity, so it could be well above or below the figure given.
A fine day on Rough Tor: summit wind broadly 5-20 mph, with gusts 15-25 mph around midday (a moderate breeze). Summits should stay clear of cloud - good visibility on top. Little or no rain expected. Bright spells with UV up to 6 - sunscreen on exposed skin. Low confidence (ensemble members are widely spread) - the summit peak could be anywhere from 9 to 21 mph; check again nearer the time.
A fine day on Rough Tor: summit wind broadly 5-15 mph, with gusts 10-20 mph during the evening (a moderate breeze). Any cloud sits well above the tops (base 500-1000 m) - clear summits. Little or no rain expected. Bright spells with UV up to 5 - sunscreen on exposed skin. Confidence moderate (ensemble members show a moderate spread) - the summit peak could reasonably be 7-13 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.
