Toronto Climate and Weather

Lake Ontario takes some of the edge off Toronto's humid continental climate. Summer (June to August) tends to be hot and very humid, while winter (December to February) is severe with heavy snowfall. The average maximum temperature in January is 28°F (-2°C), while the average maximum temperature in July is 80°F (27°C). Rainfall tends to occur throughout the year, but summer, though the sunniest season, is also usually the wettest. Autumn is perhaps the best time to travel to Toronto, as temperatures are less extreme than in summer or winter, with mild days and cool nights.
