Montreal is starting the week with a wall of heat, and it’s only going to get hotter before it breaks. The city remains under a severe heat warning, with weather experts at Environment Canada calling for dangerously high temperatures through Tuesday.
Today’s forecast is already pushing summer to the limit. Folks on the island can expect sunny skies, a high of 34°C and humidex values around 40°C. Overnight, it will only cool to about 22°C, meaning little relief before Tuesday’s peak heat hits.
Tomorrow will be the worst of it, with highs again near 34°C but feeling closer to 41°C once humidity is factored in. Even the overnight low is expected to hover around 25°C, keeping the city in a prolonged heat spell.
The good news is that Wednesday should finally bring much-needed relief. A system of showers and cloudy periods will drop the high to 26°C and the low to 19°C, making it the first time in days the temperature dips below 20°C. The rain should also help ease the heavy humidity that’s been hanging over the city since the weekend.
Heat warning tips
In the meantime, though, Environment Canada is reminding Montrealers to take precautions during the extreme heat:
- Drink water often, even before you feel thirsty
- Check on vulnerable people like seniors and those living alone
- Plan outdoor activities for cooler times of the day
- Wear lightweight, light-coloured clothing and a wide-brimmed hat
- Never leave children or pets in parked cars
