Weather in Toronto

While the Canadian climate might conjure images of polar bears and frozen tundras, Toronto’s weather is quite mild compared to other major Canadian cities, particularly in winter. Lake Ontario, the central geographic element, generates these comfortable climes, moderating both summer heat and winter cold.

You will generally experience hot, humid summers and cold, snowy winters, but these seasons are more bearable compared to cities like Montreal and Calgary. Toronto’s winters are significantly milder than Montreal’s, where temperatures can plummet well below freezing.

In summer, temperatures can reach an average high of 79°F (26°C), while in winter, they can get as cold as 16°F (-9°C). Rainfall levels are pretty high throughout the year, with about 33 inches (838 mm) of precipitation annually. Many people consider autumn the best time of year in Toronto due to the vibrant fall foliage, with mild days and cool nights perfect for exploring the city’s parks and outdoor festivals.
