Environment Canada has issued a heat warning for the Greater Montreal area, with hot and humid weather expected to arrive this week. Humidex values are forecast to reach the low to mid forties, posing a risk of heat-related illnesses.
Heat Warning Details
The warning, issued on June 29, 2026, covers Montreal and surrounding regions. Daytime temperatures are expected to soar into the mid-30s Celsius, combined with high humidity making it feel much hotter. Overnight lows will offer little relief, staying in the low 20s Celsius.
According to Environment Canada, such conditions can lead to heat stroke, heat exhaustion, and other health issues, particularly for young children, older adults, and those with chronic conditions.
Precautions and Advice
Officials urge residents to stay hydrated, avoid strenuous outdoor activities during peak heat, and check on vulnerable neighbors. Cooling centers will be opened across the city. A young girl was photographed playing in a fountain in Lachine to beat the heat, illustrating how residents are coping.
Broader Weather Context
This heat event comes amid a summer of extreme weather across Canada. Earlier in June, Edmonton recorded its wettest month on record, and a tornado watch was issued for western Manitoba. Meanwhile, Europe is experiencing record-breaking heat, with France reporting around 1,000 excess deaths linked to extreme temperatures.
Environment Canada advises staying informed through official channels and taking necessary precautions during the heat warning period.
