What is the hottest month in Canada?

Most people think of the Canadian cold and snow when they envisage Canada. However, Canada has four seasons and the summertime can come as a shock when compared to the warm weather in most places. July is normally thought to be the hottest month of the year in Canada as it presents sunshine, long days within the country and an increase in temperature.

July: Canada’s Warmest Month

In the majority of Canada, high temperatures are at their annual maximum in July. It is so different when it comes to the temperatures; they vary much with where you are:

Southern Ontario and Quebec
Daily temperatures are those of 25°C-30°C (77°F-86°F) in Toronto, Ottawa, Montreal, etc. and every so often, there are heat waves when the temperature goes above 35C (95°F). It’s not only hot, but also quite humid, especially in cities.
Prairie Provinces

Alberta, Saskatchewan and Manitoba are characterized by the warm dry summers. Summer temperatures are typically between 23°C to 28°C (73°F to 82°F) in July. Nevertheless, heat can reach temperatures over 30 degrees C (86 degrees F) even in cities such as Winnipeg. Heat can sometimes exceed 35°C (95°F) during intense heat waves

British Columbia

Areas near the sea such as Vancouver experience less summer heat which tends to range between 20°C and 25°C (68°F to 77°F). Nonetheless, hotter climates such as the Okanagan Valley, with vineyards and orchards, can experience highs above 35°C (95°F)

Atlantic Canada
The eastern provinces enjoy comfortable summer temperatures in July, often between 20°C and 26°C (68°F to 79°F), moderated by ocean breezes.
Northern Regions
Daytime temperatures can range between 15°C and 25°C in much of the Yukon and Northwest Territories, while parts of Nunavut often remain cooler, typically around 10°C to 15°C. During the summer the North is particularly attractive because of long daylight hours, known as the “Midnight Sun.”

Why July is the Peak

July’s warmth results from several factors:

High solar intensity- The sun is at its highest point in the sky, and its rays are strongest during this time of year
Long days of daylight- A lot of Canadian cities have 15-17 hours of daylight, which means the warming lasts longer with each progressing time.
Cumulative heat - The land and water have already accumulated the weeks of solar energy by the month of July leading to mean temperatures.

In summary, if you’re wondering which month is the hottest in Canada, it’s definitely July. It is a great season to hike in the Rocky mountains, kayak through pristine lakes, join a summer festival, or just go out into the sun and sit on a patio. If you want to visit the city or the wild, July is the month that would have you see the sunniest and warmest side of Canada.
