It feels like the 40s in Toronto once again. Here is when the extreme heat could end

Meteorologist Bill Coulter shares today’s sunny outlook and what to expect in the coming days across the region.

Toronto is now in the third day of a heat wave that has brought record-breaking temperatures to much of southern Ontario.

The temperature is expected to dip slightly today but the city will still see a daytime high of 33 C that will feel closer to 40 with the humidity.

Stay tuned here for LIVE updates throughout the day:

12:30 p.m. - Some pool hours extended

The City of Toronto says that it will keep eight public swimming pools open until 11:45 p.m. on Tuesday as the heat wave continues.

10 a.m. – When will the extreme heat end?

CP24 Metrologist Bill Coulter says that “fresher air” has already moved its way into some locations in northwestern Ontario and could head for Toronto once the current westerly winds shift somewhat later on Tuesday afternoon.

He says that while temperatures won’t “fall of a cliff” there will be a notable cooldown overnight with the temperature expected to dip to a low of 20 C.

“It is 17 C in Sault St. Marie and it is 31 C in Toronto. As long as the winds don’t come from the northwest, we are tapping into the heat and we are smothered by it in fact,” Coulter said. “Once we hit the late afternoon and we see in the wake of a few thunderstorms those winds start to shift you will see the cooler air start to descend.”

8:15 a.m. - Environment Canada confirms record

Environment Canada has confirmed that Monday was officially the hottest day Toronto has seen in nearly a decade as the city braces for the third consecutive day of scorching temperatures.

The mercury hit 36 C at Pearson International Airport on Monday, making it the hottest June 23 on record and the hottest temperature recorded in the city since July 13, 2016.

While Tuesday’s daytime high of 33 C is slightly cooler than Monday’s record-breaking heat, residents in the city will still face muggy conditions that are expected to make it feel in the low 40s.

Experts have cautioned people to stay indoors whenever possible and stay hydrated.

6:30 a.m. - Pools are open again

After some unexpected closures over the weekend, the city now says 15 outdoor pools are open for residents to cool off, including several with extended hours during the heat wave.

Monday’s heat led to power outages and even some school closures in Toronto. In a letter to parents, the TDSB said it was taking a number of steps to mitigate the hot weather in unairconditioned classrooms, including implementing fans and rotating students to air-conditioned common spaces within schools.

Some reprieve from the sweltering conditions is expected to come on Wednesday, which will see a high of 28 C, feeling like 33 when factoring in humidity.

Rain and daytime highs of 22 C and 24 C are in the forecast for Thursday and Friday respectively, according to Environment Canada.

“You’ll likely need the umbrellas for Thursday,” CP24 Meteorologist Bill Coulter said this week.

“Wet weather accompanies the return to more seasonable temperatures.”
