The first full week of July is expected to bring plenty of heat with it.
According to Environment Canada, a warm and humid air mass over Southern Quebec will persist over the next few days where temperatures are expected to exceed the 30-degree mark during the day and at least 20 degrees at night.
“Combined values of the temperature and the humidity will give humidex values near 40,” states the alert.
The dangerous heat is expected to last until Friday, as per the weather agency, who warns that heat warnings pose an elevated risk of heat stroke or heat exhaustion.

Environment Canada says the heat wave will begin on Tuesday and ‘feels like’ highs are expected to reach 42ºC on Friday midday, the first of back-to-back 40ºC and higher days.
The heat warning, issued in the early hours of Monday morning, is in effect for the following areas:
- Châteauguay – La Prairie area
- Laval area
- Longueuil – Varennes area
- Montréal Island area
The weather agency warns that citizens should watch for heat illness-related symptoms including dizziness, fainting, nausea, vomiting, rapid breathing and heartbeat, extreme thirst, and decreased urination frequency.
Environment Canada says the risks are greater for young children, pregnant women, older adults, people with chronic illnesses, and people working or exercising outdoors.
“Check on older family, friends and neighbours,” reads the alert. “Make sure they are cool and drinking water and never leave people or pets inside a parked vehicle.”
Citizens are reminded to drink water continually throughout the day, even when you’re not thirsty, and to wear breathable clothes.
Environment Canada is asking people to stay up to date with weather alerts, patterns, and updates.
