Heat, humidity cranks up for last half of Labour Day weekend, sticks around for back-to-school

Don’t close the book on summer just yet.

While many of us think of Labour Day weekend as the unofficial end to the summer season in the region, Mother Nature is going to throw the door wide open in terms of heat and humidity.

Monica Vaswani, an emergency preparedness meteorologist at Environment Canada, says daytime temperatures in the Barrie area are going to be reminiscent of mid-summer.

“As we head into the first week of September, especially Sunday onwards, we will be looking at daytime high temperatures anywhere from 29 to 31 degrees and humidex values possibly into the high 30s, if not the 40s.”

Overnight won’t provide much relief, as it will be muggy, and overnight lows between 18 and 20.

For folks who don’t like the heat and humidity, August was a good friend.

Vaswani says there was not a day last month where the temperature reached 30 degrees in Barrie.

“August has actually been on the cooler side,” she explains. “Normally, daytime highs on average for the month of August are about 25.1 degrees for Barrie, and so far, our overall daytime high has only been 22.8.”

Looking back to the earlier part of summer, Vaswani says southern Ontario did not see as many heat events as would normally be the case.

She expects the first and maybe even the second week of September will be above seasonal.

The normal daytime high in Barrie for this time of year is 22 and the overnight low is 11.
