WEATHER & GEOGRAPHY
WEATHER
Ontario enjoys four different seasons every year. Because the province is so big, average temperatures can vary considerably from north to south.
We have warm summers during July and August and comfortable weather in spring (May and June) and the fall (September and October). Winters can be very cold, especially in Northern Ontario. If you are used to a tropical or hot climate, be prepared to dress warmly during the winter.
Some average temperatures:
| Location | January | July |
|---|---|---|
| Toronto | -4.2C | 22.2C |
| Sudbury | -13.6C | 19.0C |
| Windsor/Essex | -4.5C | 22.7C |
