On the Coast, rainfall, sometimes relentless heavy rain, dominates in winter because of consistent barrages of cyclonic low-pressure systems from the North Pacific, but on occasion ( and not every winter ) heavy snowfalls and below freezing temperatures arrive when modified arctic air reaches coastal areas, typically for short periods.

On the opposite extreme, summers in the Southern Interior valleys are hot ; for example in Osoyoos the July Maximum averages, hot weather sometimes moves towards the Coast or to the far north of the province.

Temperatures exceed in the lower elevations of interior valleys during mid-summer, with the record high of being held in Lytton on July 16, 1941.
