Nine Standards Rigg weather forecast.

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

Cloud-free timing: Cloudy early, clearing later.

A fine day on Nine Standards Rigg: summit wind broadly 15-25 mph, with gusts 25-35 mph during the evening (fresh and blowy). Thunder watch from the morning into the evening: a small but credible risk is present. Watch for growing clouds and leave exposed tops if thunder develops. Any cloud sits well above the tops (base 900-1500 m) - clear summits. Cloud is likely to hang lowest on eastern slopes; the western side should see somewhat higher bases and better breaks. Little or no rain expected.

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

Cloud-free timing: Best around midday at about 25%; around 0% early and 0% later.

A rough, clagged-in day on Nine Standards Rigg: summit wind broadly 10-25 mph, with gusts 25-35 mph during the evening (strong winds). Thunderstorms are possible from the morning into the afternoon. Keep an escape route from exposed ridges and descend if thunder develops. There could be a spate risk based on forecast rainfall. Burns and unbridged crossings may rise quickly. Most likely from around 13:00 until around 03:00 the following day. Cloud base mostly around 500–800 m through daylight. Expect clag for much of the day, though a brief clearance is possible during the morning. Cloud is likely to hang lowest on eastern slopes; the western 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.

A grey, cloudy day on Nine Standards Rigg: summit wind broadly 5-25 mph, with gusts 20-30 mph during the evening (fresh and blowy). A meaningful thunderstorm risk is indicated from early morning into the evening. Avoid committing to exposed ridges if storms begin to build. The ground is likely to be wet after recent rain. 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. 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. Some rain is likely, with around 5-10 mm indicated; timing and local totals remain uncertain.

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

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

A rough, clagged-in day on Nine Standards Rigg: summit wind broadly 5-25 mph, with gusts 20-30 mph early in the morning (fresh and blowy). The ground is likely to be wet after recent rain. There could be a spate risk based on forecast rainfall. Burns and unbridged crossings may rise quickly. Most likely from around 14:00 until around 03:00 the following day. Cloud base around 400–700 m in the morning, then around 600–900 m around midday and 400–700 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. 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: Cloudy early, clearing later.

A mixed day on Nine Standards Rigg: summit wind broadly 10-25 mph, with gusts 25-35 mph early in the morning (fresh and blowy). A meaningful thunderstorm risk is indicated from the morning 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 400–700 m in the morning, then around 900–1200 m around midday and 700–1000 m by late afternoon. Summit cloud should lift later, bringing a better chance of clear views. 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 up to around 2 mm indicated; timing and local totals remain uncertain. Confidence moderate (forecast models agree on the walking impact of the wind) - the summit peak could reasonably be 17-28 mph, so treat the headline as mid-range.

A mixed day on Nine Standards Rigg: summit wind broadly 15-30 mph, with gusts 30-40 mph during the evening (strong winds). A meaningful thunderstorm risk is indicated from early morning 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 400–700 m in the morning, lifting to 600–900 m around midday and 700–1000 m by late afternoon. Summit cloud should lift later, bringing a better chance of clear views. 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 5-10 mm indicated; timing and local totals remain uncertain. Confidence moderate (Summit wind could be roughly 17-39 mph, which changes how difficult exposed walking may feel) - the summit peak could reasonably be 17-39 mph, so treat the headline as mid-range.
