Typical mountain and low-level wind, temperature, rainfall and sunshine for December.
40-year mountain climate
Typical high-ground conditions in December.
Historically, December has been a variable month with a useful share of better high-ground days. Of 1,240 representative high-ground days, 39% were settled for rain and wind, 31% were mixed, and 30% were poor or severe for rain and wind.
Dry days accounted for 43% of the sample. Across the whole year, the settled-day share is 39%, with around 213 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 Arrochymore is 27 hours of bright sunshine during December. 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 1,011 metres, so coastal and low-level conditions can be milder.
