Mount Keen weather forecast.

Forecast confidence: Thunderstorm timing is inherently uncertain and may shift by several hours.

Cloud-free timing: Around 0% early, improving to around 20% later.

A grey, cloudy day on Mount Keen: summit wind broadly 10-25 mph, with gusts 25-35 mph during the afternoon (fresh and blowy). Cloud base around 500–800 m in the morning, then around 1000–1300 m around midday and 500–800 m by late afternoon. The top is likely to drift in and out of cloud, with the best chance of a view from midday into the afternoon. Cloud is likely to hang lowest on southeastern slopes; the northwestern side should see somewhat higher bases and better breaks. Little or no rain expected.

Forecast confidence: Rain is possible, but forecast models differ by about 5 hours on when it arrives.

A rough, clagged-in day on Mount Keen: summit wind broadly 10-25 mph, with gusts 20-30 mph during the morning (fresh and blowy). There could be a spate risk based on forecast rainfall. Burns and unbridged crossings may rise quickly. Most likely from around 00:00 until around 02:00 the following day. Much calmer lower down - generally 0-10 mph in the valley, rising towards the tops. Cloud base mostly around 600–900 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 northern slopes; the southern side should see somewhat higher bases and better breaks. A persistently wet day is possible, with around 10-20 mm indicated; local totals could vary considerably.

Forecast confidence: Thunderstorm timing is inherently uncertain and may shift by several hours.

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

A mixed day on Mount Keen: summit wind broadly 5-15 mph, with gusts 10-20 mph early in the morning (a moderate breeze). A meaningful thunderstorm risk is indicated from around midday into the evening. Avoid committing to exposed ridges if storms begin to build. The ground is likely to be wet after recent rain. Cloud base around 600–900 m in the morning, lifting to 800–1100 m around midday and 2900–3200 m by late afternoon. The top is likely to drift in and out of cloud, with the best chance of a view from late afternoon into the evening. Some rain is likely, with up to around 2 mm indicated; timing and local totals remain uncertain.

Forecast confidence: Thunderstorm timing is inherently uncertain and may shift by several hours.

Cloud-free timing: Around 67% early, falling to around 0% later.

A grey, cloudy day on Mount Keen: summit wind broadly 10-25 mph, with gusts 20-30 mph during the afternoon (fresh and blowy). Thunderstorms are a significant hazard from the morning into the evening. Exposed summits and ridges are a poor choice while storms are nearby. Much calmer lower down - generally 0-10 mph in the valley, rising towards the tops. Cloud base around 400–700 m in the morning, lifting to 600–900 m around midday and 800–1100 m by late afternoon. Expect clag for much of the day, though a brief clearance is possible early in the morning. Some rain is likely, with around 2-5 mm indicated; timing and local totals remain uncertain. Confidence moderate (Summit wind could be roughly 11-28 mph, which changes how difficult exposed walking may feel) - the summit peak could reasonably be 11-28 mph, so treat the headline as mid-range.

Forecast confidence: Thunderstorm timing is inherently uncertain and may shift by several hours.

Cloud-free timing: Cloudy early, clearing later.

A mixed day on Mount Keen: summit wind broadly 5-35 mph, with gusts 35-45 mph during the evening (strong winds). A meaningful thunderstorm risk is indicated from the morning into the evening. Avoid committing to exposed ridges if storms begin to build. Much calmer lower down - generally 0-5 mph in the valley, rising towards the tops. Cloud base around 600–900 m in the morning, then around 1200–1500 m around midday and 1000–1300 m by late afternoon. Summit cloud should lift later, bringing a better chance of clear views. Some rain is likely, with around 2-5 mm indicated; timing and local totals remain uncertain. Low confidence (Summit wind could be roughly 14-41 mph, which changes how difficult exposed walking may feel) - the summit peak could be anywhere from 14 to 41 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.

Forecast confidence: Rain is possible, but forecast models differ by about 12 hours on when it arrives.

Cloud-free timing: Clear early, clouding up later.

A rough, clagged-in day on Mount Keen: summit wind broadly 30-50 mph, with gusts 55-65 mph early in the morning (storm-force winds). Much calmer lower down - generally 5-15 mph in the valley, rising towards the tops. Cloud base around 1800–2100 m in the morning, lowering to 400–700 m around midday and 500–800 m by late afternoon. The summit should be clear early, with cloud building around midday. Cloud is likely to hang lowest on northwestern slopes; the southeastern 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 -4 to 0°C in the wind - wrap up. Low confidence (Summit wind could be roughly 32-57 mph, which changes how difficult exposed walking may feel) - the summit peak could be anywhere from 32 to 57 mph; check again nearer the time.
