Cloud-free timing: Cloudy early, clearing later.
A mixed day on Garbh Bheinn: summit wind broadly 20-35 mph, with gusts 35-45 mph early in the morning (gale-force winds). Much calmer lower down - generally 5-15 mph in the valley, rising towards the tops. Cloud base around 800–1100 m in the morning, lifting to 1000–1300 m around midday and 3000–3300 m by late afternoon. Summit cloud should lift later, bringing a better chance of clear views. Little or no rain expected.
