About Ottawa WeatherThe climate and weather in Ottawa goes from one extreme to the other, with extremely warm and humid summers and cold, snowy winters. During the winter it snows a lot, and snow is not uncommon both in spring and autumn. Temperatures well below freezing are experienced in winter, and the bitter Ottawa weather is punctuated by the extremely cold wind chill. The best part of the cold Ottawa weather in the winter is the largest outdoor skating rink, the Rideau Canal is able to be open for months at a time!
Summer brings sunshine and pleasant days, with high humidity on many occasions, although highs seldom exceed 100°F (38°C), they can when you combine the humidity that comes from Ottawa being in a valley. Rain can be expected any time of year in Ottawa, but late summer, early fall tends to be the wettest seasons. A feature of Ottawa Weather is the possibility of late autumn heat waves, enjoyed as 'Indian summers', which frequently occur.
