Toronto is on track to set a record for the hottest July ever, according to Environment Canada.
An extreme heat alert issued for Toronto on Friday is still in effect, and Environment Canada has issued a special weather statement warning of another extended period of hot temperatures across southern Ontario.
A smog advisory issued for the city and much of the GTA was lifted on Saturday night.
This weekend, temperatures will be in the 30s, but it could feel as high as 40 C with the humidex.
“As the ride of high pressure holds, we’ll have that blazing hot sunshine through the weekend, and the UV index will be high,” said 680News meteorologist Harold Hosein.
John Klisch, from Toronto EMS, has advice for people spending time outside.
“Drink lots of fluids,” Klisch said. “It’s the simplest thing you can do. Our body’s way of getting rid of the heat is to sweat, so stay hydrated. Protect yourself from the sun if you’re vulnerable.”
He said sometimes it’s hard to tell someone is being adversely affected by the heat.
“It may be something like a mild headache, maybe a little bit of lethargy or tiredness, and it might start to progress to nausea or cramps,” Klisch said.
Anyone showing signs of overheating should get out of the sun and drink fluids.
