Alberta sure can swelter during the summer months, and the hottest temperatures ever recorded in the province will make you sweat just looking at them.

Our friends at Environment and Climate Change Canada (ECCC) dug into the archives and rounded up the hottest temperatures Alberta has ever recorded.

When you break down the hottest days by month, July is the big winner with seven of the top 10 occurring in that month, followed by two in August.
