Weather Trivia
Why is Toronto so humid in late summer?
Toronto’s position on Lake Ontario amplifies humidity. The lake acts as a moisture reservoir, and southwest winds funnel warm, moist air into the city. This combination makes humidex values climb, even when actual air temperatures are moderate. Late August often brings these “last blasts” of muggy summer before autumn’s cooler, drier air begins to dominate.
