Oppressive and Extreme Heat

Heat, especially when combined with various risk factors, can be demanding on the human body, can lead to significant discomfort and, in the most extreme cases, may also be life-threatening. In summer, heat waves need to be carefully monitored (3 consecutive days when the maximum temperature is equal to or higher than 30°C, without taking the humidex—short for humidity index—into account), as they can get worse. Such weather conditions are called oppressive heat or extreme heat. Extreme heat is one of the greatest causes of death among vulnerable people in Québec.​

High heat episodes, which are not uncommon during the summer months, may cause discomfort even when the heat is not oppressive or extreme. Normal precautions are therefore recommended throughout the season.

We ask residents to remain cautious and follow the instructions to protect yourself from the effects of the heat, especially for those who are more vulnerable.
