Toronto residents can breathe a little easier this Thursday morning as skies begin to clear after an overcast start. However, local smoke remains a concern, reducing air quality across parts of the GTA. The heat and humidity are returning—and building—toward a hot weekend ahead. Let’s explore what’s on the horizon for southern Ontario’s largest city.

Weather Trivia

Did you know?
Toronto’s urban layout creates a “heat island effect,” where the city can be up to 5°C warmer than surrounding rural areas, especially during prolonged heat spells. Concrete, asphalt, and tall buildings trap heat and slow overnight cooling—something we’ll experience this weekend.
