Gulvain weather forecast.

Cloud-free timing: Around 0% early, improving to around 83% later.

A mixed day on Gulvain: summit wind broadly 10-25 mph, with gusts 25-35 mph early in the morning (strong winds). The ground is likely to be saturated after recent rain. Expect boggy paths and rapid runoff if more rain arrives. Much calmer lower down - generally 0-10 mph in the valley, rising towards the tops. Cloud base around 500-800 m in the morning, 1500-1800 m around midday and 1100-1400 m by late afternoon. The top is likely to drift in and out of cloud, with the best chance of a view from around midday into the evening. Little or no rain expected. Cold on top: air temperature broadly 2 to 6°C, feeling around -2 to 2°C in the wind - wrap up.

A rough, clagged-in day on Gulvain: summit wind broadly 35-50 mph, with gusts 60-70 mph around midday (storm-force winds). The ground is likely to be saturated after recent rain. Expect boggy paths and rapid runoff if more rain arrives. There could be a spate risk based on forecast rainfall. Burns and unbridged crossings may rise quickly. Most likely from around 02:00 until around 22:00. Much calmer lower down - generally 10-20 mph in the valley, rising towards the tops. Cloud base mostly around 500-800 m through daylight. Expect the top to stay in cloud for most or all of daylight, with no dependable break. Cloud is likely to hang lowest on southwestern slopes; the northeastern side should see somewhat higher bases and better breaks. Some rain is likely, with around 5-10 mm indicated; timing and local totals remain uncertain. Cold on top: air temperature broadly 4 to 8°C, feeling around -2 to 2°C in the wind - wrap up. Low confidence (ensemble members are widely spread) - the summit peak could be anywhere from 30 to 58 mph; check again nearer the time.

A rough, clagged-in day on Gulvain: summit wind broadly 40-55 mph, with gusts 65-75 mph during the morning (storm-force winds). Much calmer lower down - generally 10-20 mph in the valley, rising towards the tops. Cloud base mostly around 500-800 m through daylight. Expect the top to stay in cloud for most or all of daylight, with no dependable break. Cloud is likely to hang lowest on southwestern slopes; the northeastern side should see somewhat higher bases and better breaks. Some rain is likely, with around 5-10 mm indicated; timing and local totals remain uncertain. Cold on top: air temperature broadly 6 to 10°C, feeling around 0 to 4°C in the wind - wrap up. Low confidence (ensemble members are widely spread) - the summit peak could be anywhere from 26 to 65 mph; check again nearer the time.

Cloud-free timing: Around 0% early, improving to around 50% later.

A rough, clagged-in day on Gulvain: summit wind broadly 20-40 mph, with gusts 45-55 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 500-800 m in the morning, lifting to 900-1200 m around midday and 800-1100 m by late afternoon. Expect clag for much of the day, though a brief clearance is possible during the evening. Cloud is likely to hang lowest on western slopes; the eastern side should see somewhat higher bases and better breaks. Some rain is likely, with around 2-5 mm indicated; timing and local totals remain uncertain. Cold on top: air temperature broadly 4 to 8°C, feeling around -2 to 2°C in the wind - wrap up. Low confidence (ensemble members are widely spread) - the summit peak could be anywhere from 22 to 48 mph; check again nearer the time.

A fine day on Gulvain: summit wind broadly 0-15 mph, with gusts 10-20 mph early in the morning (a moderate breeze). The ground is likely to be wet after recent rain. Any cloud sits well above the tops (base 1000-1600 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 6 to 21 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.

Cloud-free timing: Around 25% early, improving to around 50% later.

A mixed day on Gulvain: summit wind broadly 10-30 mph, with gusts 30-40 mph during the evening (strong winds). Much calmer lower down - generally 0-10 mph in the valley, rising towards the tops. Cloud base around 600-900 m in the morning, 2000-2300 m around midday and 1000-1300 m by late afternoon. The top is likely to drift in and out of cloud, with the best chance of a view from the morning into the evening. Little or no rain expected. Low confidence (ensemble members are widely spread) - the summit peak could be anywhere from 15 to 32 mph; check again nearer the time.

Cloud-free timing: Around 50% early, falling to around 0% later.

A rough, clagged-in day on Gulvain: summit wind broadly 25-40 mph, with gusts 45-55 mph early in the morning (gale-force winds).

Expect clag for much of the day, though a brief clearance is possible early in the morning. Cloud is likely to hang lowest on southern slopes; the northern side should see somewhat higher bases and better breaks. Some rain is likely, with around 5-10 mm indicated; timing and local totals remain uncertain. Low confidence (ensemble members are widely spread) - the summit peak could be anywhere from 21 to 66 mph; check again nearer the time.
