Ottawa's Climate

Ottawa, Canada's capital, sits well inland in Ontario on the banks of the Ottawa River and has a humid continental climate with sharply contrasting seasons. Winters (December–March) are very cold and snowy, typically -15 to -5°C, with cold snaps below -25°C and a frozen canal that turns into a skateway. Summers (June–August) are warm and humid, usually 25–30°C and sometimes above 32°C with thunderstorms. Spring and autumn are brief transitions: fall (September–October) is crisp with brilliant foliage, while spring brings a muddy thaw.
