How we pick the best months

  • Best: an average temperature of 1528°C and low rainfall for Toronto: under 150 mm, and no more than 83 mm, a quarter above Toronto's median month (never set below 60 mm).
  • If no month qualifies, we show the three driest months that average 10–30°C instead.
  • Wet: 150 mm of rain or more. Rainy: more than 83 mm. Hot: 29°C or more on average. Cool: under 15°C. Cold: under 5°C.

Averages cover day and night, so afternoons are warmer than the figure shown. Weather is only one reason to pick a month: school holidays, festivals and prices matter too.

Where these numbers come from

Monthly averages for January 2001 – December 2020 from the NASA POWER project, for the area around Pearson (YYZ) at 43.68, -79.63. The model covers a grid about 50 km across, so a coastal or hilly spot can run a degree or two different. Retrieved 12 September 2026.
