Ben Rinnes weather forecast.

Forecast confidence: A low thunderstorm risk remains difficult to time precisely.

Cloud-free timing: Around 67% early, falling to around 40% later.

A mixed day on Ben Rinnes: summit wind broadly 15-35 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 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 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 6 hours on when it arrives.

A grey, cloudy day on Ben Rinnes: summit wind broadly 10-20 mph, with gusts 20-30 mph during the evening (fresh and blowy). 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 northern slopes; the southern 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.

Forecast confidence: A low thunderstorm risk remains difficult to time precisely.

Cloud-free timing: Around 0% early, improving to around 40% later.

A mixed day on Ben Rinnes: summit wind broadly 5-25 mph, with gusts 25-35 mph early in the morning (fresh and blowy). Thunderstorms are possible from around midday into the evening. Keep an escape route from exposed ridges and descend if thunder develops. Much calmer lower down - generally 0-10 mph in the valley, rising towards the tops. Cloud base around 400–700 m in the morning, then around 800–1100 m around midday and 600–900 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. Some rain is likely, with up to around 2 mm indicated; timing and local totals remain uncertain. Confidence moderate (Summit wind could be roughly 13-28 mph, which changes how difficult exposed walking may feel) - the summit peak could reasonably be 13-28 mph, so treat the headline as mid-range.

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

Cloud-free timing: Around 0% early, improving to around 80% later.

A mixed day on Ben Rinnes: summit wind broadly 5-20 mph, with gusts 15-25 mph around midday (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. Cloud base around 300–600 m in the morning, lifting to 600–900 m around midday and 1300–1600 m by late afternoon. The top is likely to drift in and out of cloud, with the best chance of a view during the afternoon. Some rain is likely, with around 5-10 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.

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

Cloud-free timing: Best around midday at about 100%; around 0% early and 0% later.

Forecast confidence: Rain is possible, but forecast models differ by about 14 hours on when it arrives.

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

A rough, clagged-in day on Ben Rinnes: summit wind broadly 30-40 mph, with gusts 45-55 mph around midday (gale-force winds). 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 23:00. Much calmer lower down - generally 10-20 mph in the valley, rising towards the tops. Cloud base around 1300–1600 m in the morning, lowering to 400–700 m around midday and 500–800 m by late afternoon. Expect clag for much of the day, though a brief clearance is possible early in the morning. Cloud is likely to hang lowest on northwestern slopes; the southeastern 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. Cold on top: air temperature broadly 4 to 8°C, feeling around -2 to 2°C in the wind - wrap up. Confidence moderate (Summit wind could be roughly 28-46 mph, which changes how difficult exposed walking may feel) - the summit peak could reasonably be 28-46 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.
