Believe it or not, it actually gets very hot in Canada in the summer. It surprised me too when I first came here. I thought the temperature would be in the twenties degrees Celsius, at most!
Summers in Ottawa are typically hot, humid, hazy and stuffy. Some people love it (I do!), some people hate it and can’t wait for cooler temperatures. It’s true that they can sometimes be hard to deal with. Houses are built for the winter and tend to trap the heat. Most people use air-con but I’m not a huge fan, I find it makes the air really dry.
In winter, people measure the cold using the “windchill” factor. During the summer, we go by the “humidex”, an index to describe how hot the weather feels to the average person. Canadian meteorologists love to invent new words!
