Foel-fras weather forecast.

A grey, cloudy day on Foel-fras: summit wind broadly 15-30 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 600-900 m - expect clag for much of the day, though a brief clearance is possible from late afternoon into the evening. Cloud will be lowest on the W slopes, down to about 500-800 m; the E side should be clearer, lifting to around 700-1000 m. Little or no rain expected. Cold on top: air temperature broadly 4 to 8°C, feeling around -2 to 2°C in the wind - wrap up.

A mixed day on Foel-fras: summit wind broadly 10-20 mph, with gusts 20-30 mph during the afternoon (fresh and blowy). Cloud base 600-1400 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. The cloud base is very changeable today - it could sit much higher or lower than that at times, so read the sky. Little or no rain expected.

A mixed day on Foel-fras: 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. Any cloud sits well above the tops (base 1500-3200 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 18-33 mph, so treat the headline as mid-range. 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 mixed day on Foel-fras: summit wind broadly 10-30 mph, with gusts 30-40 mph early in the morning (strong winds). Much calmer lower down - generally 0-10 mph in the valley, rising towards the tops. Any cloud sits well above the tops (base 1600-3100 m) - clear summits. 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 19 to 40 mph; check again nearer the time. Treat the cloud base with caution - the models disagree on humidity, so it could be well above or below the figure given.

Cloud base 500-1400 m - the top is likely to drift in and out of cloud, with the best chance of a view from late afternoon 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. Little or no rain expected. Low confidence (ensemble members are widely spread) - the summit peak could be anywhere from 6 to 17 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.

A fine day on Foel-fras: summit wind broadly 10-25 mph, with gusts 25-35 mph during the evening (fresh and blowy). Any cloud sits well above the tops (base 1100-2100 m) - clear summits.
