Typical mountain and low-level wind, temperature, rainfall and sunshine for September.
40-year mountain climate
Typical high-ground conditions in September.
Historically, September has been one of the more promising parts of the year for high-ground days. Of 1,200 representative high-ground days, 36% were settled for rain and wind, 41% were mixed, and 23% were poor or severe for rain and wind.
Dry days accounted for 39% of the sample. Across the whole year, the settled-day share is 33%, with around 231 wet days, so a region's strongest month should not be mistaken for its usual climate. As a separate check, the Met Office 1991–2020 average at Loch Glascarnoch is 92 hours of bright sunshine during September. Cloud and views are deliberately kept out of the settled-day score because they vary sharply between individual summits; check the live forecast nearer the trip. These figures describe representative high ground around 1,055 metres, so coastal and low-level conditions can be milder.
