Glamaig weather forecast.

Cloud-free timing: Around 75% early, falling to around 33% later.

A mixed day on Glamaig: summit wind broadly 10-30 mph, with gusts 30-40 mph during the evening (strong 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 01:00 until around 03:00 the following day. Much calmer lower down - generally 5-15 mph in the valley, rising towards the tops. Cloud base around 1400-1700 m in the morning, lowering to 1000-1300 m around midday and 500-800 m by late afternoon. The top is likely to drift in and out of cloud; views may come and go. 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 rough, clagged-in day on Glamaig: summit wind broadly 40-50 mph, with gusts 60-70 mph during the morning (storm-force winds). The ground is likely to be saturated after recent rain. Expect boggy paths and rapid runoff if more rain arrives. High spate risk based on forecast rainfall. Burns and unbridged crossings may become difficult or impassable. Most likely from around 00:00 until around 23:00. Much calmer lower down - generally 15-25 mph in the valley, rising towards the tops. Cloud base mostly around 300-600 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. A persistently wet day is possible, with around 5-10 mm indicated; local totals could vary considerably. Confidence moderate (ensemble members show a moderate spread) - the summit peak could reasonably be 42-57 mph, so treat the headline as mid-range.

A rough, clagged-in day on Glamaig: summit wind broadly 40-55 mph, with gusts 65-75 mph during the morning (storm-force winds). The ground is likely to be wet after recent rain. Severe spate risk based on forecast rainfall. Burns and unbridged crossings may become unsafe or impassable. Most likely from around 04:00 until around 06:00 the following day. Much calmer lower down - generally 15-25 mph in the valley, rising towards the tops. Cloud base mostly around 300-600 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. A persistently wet day is possible, with more than 40 mm indicated; local totals could vary considerably. Confidence moderate (ensemble members show a moderate spread) - the summit peak could reasonably be 43-58 mph, so treat the headline as mid-range.

Cloud-free timing: Around 25% early, improving to around 67% later.

A grey, cloudy day on Glamaig: summit wind broadly 15-30 mph, with gusts 30-40 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 5-15 mph in the valley, rising towards the tops. Cloud base mostly around 700-1000 m through daylight. The top is likely to drift in and out of cloud, with the best chance of a view 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 up to around 2 mm indicated; timing and local totals remain uncertain. Cold on top: air temperature broadly 4 to 8°C, feeling around 0 to 4°C in the wind - wrap up. Confidence moderate (ensemble members show a moderate spread) - the summit peak could reasonably be 19-31 mph, so treat the headline as mid-range.

Cloud-free timing: Around 50% early, improving to around 100% later.

A fine day on Glamaig: summit wind broadly 0-15 mph, with gusts 10-20 mph early in the morning (a moderate breeze). The ground is likely to be saturated after recent rain. Expect boggy paths and rapid runoff if more rain arrives. Any cloud sits well above the tops (base 800-1300 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 16 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 50% early, improving to around 100% later.

A mixed day on Glamaig: summit wind broadly 15-35 mph, with gusts 40-50 mph during the evening (gale-force winds). The ground is likely to be wet after recent rain. Much calmer lower down - generally 0-10 mph in the valley, rising towards the tops. Any cloud sits well above the tops (base 1100-2100 m) - clear summits. Little or no rain expected. Low confidence (ensemble members are widely spread) - the summit peak could be anywhere from 17 to 50 mph; check again nearer the time.

Cloud-free timing: Around 100% early, falling to around 0% later.

A rough, clagged-in day on Glamaig: summit wind broadly 35-45 mph, with gusts 55-65 mph during the evening (storm-force winds). There could be a spate risk based on forecast rainfall.
