What’s the weather like in Calgary in August?

Calgary is a beautiful city in southern Canada, sitting in the province of Alberta not far from the Rocky Mountains. It has a climate which brings warm but damp summers to the city, and temperatures are at their peak in August, so this is the best month to visit if you want the warmest weather. As well as 11 hours of sunshine each day in August, rain showers and chilly evenings are also common, so you’ll need to pack for all weathers if you’re visiting Calgary at this time.


The average temperature in Calgary is 17ºC in August, reaching highs of 24ºC in the peak of the afternoon. The average low drops to a cool 9ºC at night, so you’ll need some warmer layers for evenings out. Calgary expects around 50mm of rain over the course of nine days in August, although you can still look forward to 11 hours of sunshine each day at this time.
