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 expected on 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.

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, 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 warming on Sunday, with temperatures expected to top out at a record-beating 33 degrees, with a humidex of 42. The UV index will be 8 or very high.

The previous record for Aug. 22 was 30.6, set in 1955.

The average high for Aug. 22 is 24.1 and the average low is 13.6.

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 temperature is expected to drop to 22 overnight from Sunday to Monday.

On Saturday night at 11, It was still 25.7 degrees with a humidex of 34. As of 8 a.m. Sunday, the temperature was 25, with a humidex of 34.

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.
