Càrn an Fhreiceadain weather forecast.

A fine day on Càrn an Fhreiceadain: summit wind broadly 5-20 mph, with gusts 20-30 mph during the afternoon (fresh and blowy). Any cloud sits well above the tops (base 1300-1600 m) - clear summits. Little or no rain expected.

A grey, cloudy day on Càrn an Fhreiceadain: summit wind broadly 5-20 mph, with gusts 15-25 mph during the afternoon (fresh and blowy). Cloud base mostly around 400–700 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.

Cloud-free timing: Cloudy early, clearing later.

A mixed day on Càrn an Fhreiceadain: summit wind broadly 5-15 mph, with gusts 10-20 mph during the afternoon (a moderate breeze). Cloud base around 400–700 m in the morning, lifting to 800–1100 m around midday and 1300–1600 m by late afternoon. Summit cloud should lift later, bringing a better chance of clear views. Little or no rain expected.

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

Cloud-free timing: Cloudy early, clearing later.

A mixed day on Càrn an Fhreiceadain: summit wind broadly 5-20 mph, with gusts 15-25 mph during the evening (a moderate breeze). A meaningful thunderstorm risk is indicated from the morning into the evening. Avoid committing to exposed ridges if storms begin to build. Cloud base around 400–700 m in the morning, lifting to 800–1100 m around midday and 1300–1600 m by late afternoon. Summit cloud should lift later, bringing a better chance of clear views. 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. 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: Around 0% early, improving to around 20% later.

A mixed day on Càrn an Fhreiceadain: summit wind broadly 5-30 mph, with gusts 30-40 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. Cloud base around 300–600 m in the morning, then around 1200–1500 m around midday and 300–600 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 afternoon. Some rain is likely, with around 2-5 mm indicated; timing and local totals remain uncertain. Low confidence (Summit wind could be roughly 15-39 mph, which changes how difficult exposed walking may feel) - the summit peak could be anywhere from 15 to 39 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 14 hours on when it arrives.

A rough, clagged-in day on Càrn an Fhreiceadain: summit wind broadly 20-30 mph, with gusts 30-40 mph early in the morning (strong winds). 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 23:00. Much calmer lower down - generally 10-20 mph in the valley, rising towards the tops. Cloud base mostly around 400–700 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 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 2 to 6°C, feeling around -4 to 0°C in the wind - wrap up. Confidence moderate (Summit wind could be roughly 18-32 mph, which changes how difficult exposed walking may feel) - the summit peak could reasonably be 18-32 mph, so treat the headline as mid-range.
