Historical weather data, all-time temperature records, and monthly climate averages for Toronto, ON, Canada. Explore typical weather conditions by week for trip planning, and see how today compares to the historical record.
April 4th in Toronto is a coin-flip kind of day—there's a 67% chance of precipitation and a 1-in-4 shot it comes down as snow. Expect something in the mid-40s, though history has swung wildly: a balmy 66° back in 1981 and a brutal 8° low in 1964.
Toronto's weather has real teeth on both ends. The city has baked at 97° (June 2025) and frozen at -18° (January 1981), a 115-degree spread that demands a serious wardrobe. A November storm in 1962 dumped 2.31" of rain in a single day, while January 2022 buried the city under 9.7" of snow.
July is Toronto's sweet spot, with highs peaking around 77-78° in mid-month before gradually easing into a pleasant September at 69°. Winter is the real test—January and February hover in the upper 20s and low 30s, making mid-January the coldest stretch of the year. If you're trying to dodge rain, avoid mid-to-late June, which is the wettest week on average.
