Calgary - Recent May Temperatures, Rain & Snow





The numbers here describe what the May weather in Calgary, Alberta Canada was like for every year since 2010. A series of tables gives May data by year for temperature, precipitation and snowfall.

They begin with average maximum and minimum temperatures in degrees Fahrenheit and Celsius. That's followed by how many hot or cold days occurred each May. Then there's information on how much rain and snow actually landed this month during recent years, as well as how often Calgary had wet or snowy weather.

The climate data come from weather measurements made at Calgary International Airport.
