A mixed day on Gragareth: summit wind broadly 15-35 mph, with gusts 35-45 mph early in the morning (strong winds). Much calmer lower down - generally 5-15 mph in the valley, rising towards the tops. Cloud base 500-1100 m - the top is likely to drift in and out of cloud, with the best chance of a view from around midday into the evening. Cloud will be lowest on the W slopes, down to about 700-1000 m; the E side should be clearer, lifting to around 900-1200 m. Little or no rain expected.

A mixed day on Gragareth: summit wind broadly 15-30 mph, with gusts 30-40 mph during the afternoon (strong winds). Any cloud sits well above the tops (base 800-3200 m) - clear summits. Little or no rain expected. Bright spells with UV up to 6 - sunscreen on exposed skin. Confidence moderate (ensemble members show a moderate spread) - the summit peak could reasonably be 19-27 mph, so treat the headline as mid-range.

A mixed day on Gragareth: summit wind broadly 5-15 mph, with gusts 10-20 mph early in the morning (a moderate breeze). Cloud base 500-1600 m - the top is likely to drift in and out of cloud, with the best chance of a view from the morning into the evening. The cloud base is very changeable today - it could sit much higher or lower than that at times, so read the sky. 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. Low confidence (ensemble members are widely spread) - the summit peak could be anywhere from 6 to 17 mph; check again nearer the time.

A fine day on Gragareth: summit wind broadly 15-25 mph, with gusts 25-35 mph during the evening (fresh and blowy). 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 12 to 32 mph; check again nearer the time. 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.
