Weather & Seasons

Toronto weather and its climate is modified by its location on the shores of Lake Ontario. The water in the lake ensures Toronto is warmer in winter and cooler in summer than it would otherwise be. Blessed with four distinct seasons, the weather in Toronto differs considerably throughout the year.

Toronto Weather & Things To Do

Toronto is a northern city, therefore summers are hot, and the winters very cold and long. However, whether it’s sunny and warm, or cold there’s plenty to see and do. If anything, the weather in Toronto only compliments the activities available. Skiing, snowboarding and skating are popular things to do in winter for locals and visitors. Summer is all about hitting the beach, sunbathing, cycling, tennis and exploring the city on foot. No matter the season, you’ll have fun in Toronto.


Summer officially starts in late June, however, Torontonians generally only consider July and August as the real summer months. The city can get pretty hot during the season with temperatures sometimes reaching above 30C during the day. The Great Lakes location is the source of Toronto’s summer humidity, which many people find uncomfortable. Like most cities, central areas can get very hot and smoggy. Exploring beyond the high rise buildings and into more open green spaces can bring some relief from the summer heat. When the sun has got his hat on, Torontonians are known for cracking open a beer on their terraces and watching the world go by.


September through until December is Autumn (also called Fall) in Toronto. Toronto weather during Autumn can be a little mixed as the warm summer evenings make way to cooler autumnal days. Leaves on the trees turn from vibrant green to every shade of yellow, orange, red and brown. A picturesque sight to witness anywhere in the city. Rain is not uncommon at this time of year, nor are temperatures that hover around 10C.


Winter weather in Toronto can be extremely harsh. From December until March it is very cold and snow fall is common. Temperatures in the city rarely peak above 0C and sometimes even go as low as -25C. With the snow, however, brings plenty of winter sports opportunities, such as skiing, snowboarding and skating. Christmas in Toronto is magical.


During the months March to June the climate can be warm during the day but cool at night. Average highs reach 14C and there is often a large amount of rain. Spring is considered the wettest season in the city so an umbrella and rain jacket are an essential accessory for most. March and April are generally much cooler than May and June.
