The calendar may say September, but today could be the hottest day of the year in Toronto with scorching temperatures and high humidity threatening to break records in southern Ontario.
Toronto temperatures reached 34 C today, with humidity making it feel more like 43. The City of Toronto issued a heat alert early Tuesday morning, and public cooling centres opened for the day.
The same weather is being felt in much of southern and southwestern Ontario, with temperatures hitting 34 C in Windsor, Kitchener-Waterloo and London by Tuesday afternoon.
A humidex advisory is in effect for Toronto and much of southwestern Ontario.
"I’m already starting to feel the humidity," said CBC News reporter Linda Ward at 6:30 a.m. ET on Tuesday. "Outdoor pools in the city are already closed so people are advised to drink plenty of water and get into an air-conditioned environment."
The Toronto temperature record for Sept. 10 is 34.8 C, set back in 2002. Windsor temperatures would have to hit 35 C today to set a record.
The record for the hottest September day in Toronto is not in jeopardy today. That was set back in 1953 when temperatures hit 37 C.
Things will cool down on Wednesday, where the forecast high in Toronto is 31 C with showers and thunderstorms in the forecast. Temperatures in other southern Ontario cities will see a similar dip on Wednesday.
