Ontario Climate & Weather
Ontario's climate is continental, meaning the province experiences hot, humid summers and very cold winters with heavy snowfall. Spring and autumn tend to be milder. Due to the Great Lakes, the province experiences far less variation in its temperatures year round, and more precipitation than would be expected for such a central region.
Cities located farther away from the lakes in the south of the province are much hotter, and temperatures can reach around 80°F (27°C), with possible heat waves. In winter, areas north of the Great Lakes tend to be much colder, with more severe winters caused by arctic air currents. Temperatures can range between 36°F (0°C) and 14°F (-10°C).
