The Canadian Rockies experience a highland climate, characterised by warm summer days with long hours of sunshine, and cold, crisp winters when snow covers the ground from November to March. The coldest months are December and January when temperatures can plummet to well below freezing, exacerbated by the wind chill factor. Hikers in the summer months should note that May and June are the wettest time of year, and that even in summer weather conditions can be changeable and unpredictable.
