Records in danger of falling as Quebec gripped by extreme heat

Tuesday, July 7th 2020, 11:50 am - A long, very dry stretch is being capped off by some of the hottest temperatures the Montreal area has seen in years.

Heat warnings are in effect in and around the Montreal area, and even areas somewhat north of there are expected to be uncomfortably hot in the coming days.

"Beginning Tuesday, temperatures will exceed the 30-degree mark during the day and will not fall below 20 degrees at night," Environment Canada warns. "The combined temperature and humidity values will give humidex values of 40."

It's the same hot and humid air mass that's been afflicting neighbouring southern Ontario for the past few days, and like in Ontario, the odds are better than even of a broken record or two in Quebec.

Presently, forecasters expect the first 12 days of July are likely to be the warmest July stretch on record for not only the Montreal area, but Ottawa as well, meaning Gatineau is also likely to be included in that record.


More than that, forecasters are watching the temperature readings this week at Pierre Elliott Trudeau Airport. If Montreal reaches its forecast daytime high of 36°C on Friday, it will officially be the warmest July day ever recorded for that station, edging out the 35.6°C that was recorded there on July 21st, 2011.

And though the province has seen some highly localized downpours in the occasional thunderstorm in recent days, that wouldn't be nearly enough to reverse the effects of what's been a very long period of arid conditions.

In fact, as of Monday, Montreal has experienced its driest-ever May 1st to July 6th period, with only 81 mm. To put that in perspective, that's about what the city gets for the entire month of May alone.


With this kind of persistent extreme heat, people in the province should make sure to look after themselves and others. Environment Canada asks that people keep in mind:

  • 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. Make sure they are cool and drinking water
  • Never leave people or pets inside a parked vehicle.
  • Watch for the symptoms of heat illness: dizziness/fainting; nausea/vomiting; rapid breathing and heartbeat; extreme thirst; decreased urination with unusually dark urine.
  • Outdoor workers should take regularly scheduled breaks in a cool place.
