Summer in Toronto 2025
Hot and humid season is still tourists' favourite
Best time: June, July, August
Toronto’s climate is generally sunny, and most of the sun naturally falls on summer. The hot weather starts in late June. July hits the highest marks on thermometers, and this weather continues into early September.
Seasonal drawbacks might be intense humidity coming from Lake Ontario, and uncomfortable heat. Another inconvenience is rain, which is most frequent in July, not only the hottest but also the rainiest month. Besides, Toronto’s summer is known for seasonal smogs.
Despite all that, summer remains tourists’ favourite season when one can enjoy the city itself, as well as delight in beach holiday and explore Toronto’s islands.
