Toronto is in the middle of a three day heat event that doesn’t quite meet the criteria for a heat wave, which Environment Canada says is three straight days of temperatures 32 Celsius or higher.
Wednesday, the temperature hit 30.5 degrees to usher out the month of May, narrowly missing the record of 31.1 degrees set on May 31, 1944.
Record breaking heat is expected on Thursday June 1st. The forecast high is 31. The previous record is 28.3 degrees set on June 1st, 1948.
Toronto will also likely break a high temperature record on Friday June 2nd. If the temperature reaches the forecast high of 31 degrees, it will break the previous record of 29.4 Celsius set on June 2nd, 1943.
According to an Environment Canada heat warning, “hot and humid air can also bring deteriorating air quality and can result in the Air Quality Health Index approaching the high risk category.”
“The risks are greater for young children, pregnant women, older adults, people with chronic illnesses and people working or exercising outdoors,” says the weather agency’s warning.
People are advised to drink plenty of water and remain in cooler places if possible.
Temperatures are forecast to be a bit more comfortable over the weekend, with seasonal highs in the low 20s.
