July is the warmest month across most of Canada, with average highs ranging from the low 20s °C on the coasts to the mid-20s or low 30s °C inland. Expect long daylight hours, occasional thunderstorms, and peak summer humidity, especially in southern Ontario and Quebec.
What does July weather look like across Canada?
In July, the country splits between a comfortable Pacific maritime climate and a hotter, more humid continental interior. Vancouver sees average highs around 22 °C with little rain, while Calgary and Edmonton climb to the mid-20s °C with afternoon thunderstorms. Southern Ontario, including Toronto, often reaches 27–30 °C with high humidity, making it one of the muggiest regions. For a detailed look at your city, see our Toronto weather or Calgary weather pages. The Canada weather hub provides full provincial and territorial breakdowns.
How should you prepare for July heat and storms?
Humidity and UV index are key considerations in July. The sun is strong from late morning to mid-afternoon, especially in the Prairies and southern Ontario. Thunderstorms develop quickly inland, often in the late afternoon or evening, bringing brief heavy rain, lightning, and gusty winds. Checking a july weather hourly forecast can help you plan outdoor activities. For heat warnings and severe thunderstorm watches, refer to our weather warning page.
