Cloud-free timing: Cloudy early, clearing later.
A wild day on Bowfell: summit wind broadly 15-40 mph, with gusts 40-50 mph during the evening (gale-force winds). Much calmer lower down - generally 10-20 mph in the valley, rising towards the tops. Little or no rain expected. Confidence moderate (forecast models agree on the walking impact of the wind) - the summit peak could reasonably be 31-36 mph, so treat the headline as mid-range.
