A mixed day on Rhobell Fawr: summit wind broadly 5-20 mph, with gusts 15-25 mph early in the morning (a moderate breeze). Some rain is likely, with up to around 2 mm indicated; timing and local totals remain uncertain. 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 Rhobell Fawr: summit wind broadly 10-25 mph, with gusts 20-30 mph during the morning (fresh and blowy). Much calmer lower down - generally 0-10 mph in the valley, rising towards the tops. Any cloud sits well above the tops (base 1300-1600 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 17-23 mph, so treat the headline as mid-range. Treat the cloud base with caution - the models disagree on humidity, so it could be well above or below the figure given.
