 The hottest temperatures recorded in Alberta vary from more than 40C in southeast Alberta to less than 32C in the mountains. The highest extreme maximum temperatures occur in southeast Alberta. The area north of the Battle River and the northeast corner of Alberta have higher extreme maximum temperatures than the surrounding areas. Lower elevations and drier soils contribute to higher temperatures. Plants suffer from heat stress when temperatures exceed 30C for a period of time.

This map is based on temperatures recorded between 1901 and 2000. It does not represent the entire period of record for all stations because some of the station records started prior to 1901; warmer temperatures may have occurred prior to 1901.
