Toronto’s climate

Ontario, Canada · 43.65°N, 79.38°W · America/Toronto

Toronto has a humid continental climate with four clear seasons. Winters are cold and snowy, with January highs around -1°C and lows near -9°C, while summers are warm and humid, with July highs about 27°C and lows near 17°C. Lake Ontario moderates the extremes, keeping the city slightly milder than inland areas in winter.

Heatwaves above 32°C and cold outbreaks below -20°C both occur from time to time, and humidity and wind chill make them feel harsher.

Switch between daily, weekly, monthly and yearly views to compare a single date, a rolling week or month, or a full year. Dates are resolved in Toronto's own timezone (America/Toronto), not yours.
