It's not just a heat wave, it's a record-breaker. And it's not going away - Montreal Gazette

Even though meteorologists initially had said the heat wave would be over by this weekend, they now don't expect a return to normal temperatures before next Friday as the warm and humid air mass lingers on.

With record-breaking highs in Montreal on Saturday and Sunday, this week’s sweltering weather could make this August the hottest on record.

“It’s a good candidate for being the hottest month of August,” said Simon Legault, a meteorologist with Environment Canada.

So far this month, the average temperature has been 23.4. That beats the record average for August of 22.9 in 2018, followed by an average of 22.7 degrees in August 2016.

Though meteorologists initially had said the heat wave would be over by this weekend, they now don’t expect a return to normal temperatures before Friday as the warm and humid air mass lingers on, Legault said.

“As the days passed, we saw that the heat was going to last longer,” he said.

“It’s an abnormal heat wave in terms of its duration,” he added.

Environment Canada again issued a heat warning on Sunday, as the temperature hit 31.5 degrees, with a humidex of 40. The UV index was 8 or very high.

The previous record for Aug. 22 was 30.6, set in 1955. The average high is 24.1 and the average low is 13.6.

Quebec Premier François Legault issued a tweet on Sunday asking Quebecers to reach out to people living alone and make sure everyone was staying hydrated and safe.

“We need to protect our elders and those without air conditioners who are more vulnerable,” the premier said.

On Saturday, the thermometer soared to 33.3 degrees at Trudeau airport, with a humidex of 41. That beat the record of 32.8 set in 1955. The average high for Aug. 21 is 24.2 degrees and the average low is 13.8.

With temperatures stuck in the 20s overnight, there’s no relief from the sultry weather. The forecast shows highs around 30 and lows around 20 until Thursday night. Daytime humidex values will remain above 35 for much of next week.

“Next weekend, we’ll go back to days that are less hot,” Legault said.

    Fitness: Here’s what happens when you exercise during a heat wave

Young children, pregnant women, older adults, people with chronic illnesses and people working or exercising outdoors are particularly at risk from the heat.

People are urged to drink plenty of water, even before they feel thirsty, and stay in a cool place.

Check on older family, friends and neighbours to make sure they are cool and drinking water.

Never leave people or pets inside a parked vehicle.
