Cloud-free timing: Around 0% early, improving to around 80% later.
A mixed day on Benvane: summit wind broadly 15-30 mph, with gusts 30-40 mph during the evening (strong winds). Much calmer lower down - generally 5-15 mph in the valley, rising towards the tops. Cloud base around 500-800 m in the morning, lifting to 1000-1300 m around midday. 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 is likely to hang lowest on eastern slopes; the western side should see somewhat higher bases and better breaks. Little or no rain expected. Confidence moderate (forecast models agree on the walking impact of the wind) - the summit peak could reasonably be 23-28 mph, so treat the headline as mid-range.
