Climate

London has a humid continental climate. Because of its location in the continent and proximity to the Great Lakes, London experiences very contrasting seasons. The summers are usually warm to hot and humid, while the winters are normally quite cold but with frequent thaws. London has the most thunderstorms of any area in Canada due to the lake breeze convergence. For its southerly location within Canada, it does receive quite a lot of snow, averaging slightly over 200 cm per year. The majority of this is lake effect snow originating from Lake Huron, some 60 km to the northwest which occurs when strong, cold winds blow from that direction.
