Dangerously high temperatures are expected once again today (July 20) in Mississauga, Brampton and Caledon as most of southern Ontario remains under a heat warning issued by Environment Canada.
It’s the second-straight day the national weather agency has issued a heat warning for the Peel area as temperatures are expected to remain around the 31C mark with the humidex making it feel like the high 30s or low 40s.
Environment Canada issued the latest warning this morning (July 20) at about 5:20 a.m., noting that “hot and humid conditions are expected today.”
Again, an overnight low near 20C tonight isn’t expected to bring much relief, weather officials note, adding slightly cooler temperatures are expected on Thursday.
However, some areas of southern Ontario could see high temperatures linger into the weekend.
The weather agency added that hot and humid air “can also bring deteriorating air quality and can result in the Air Quality Health Index approaching the high-risk category.”

Officials warn people to watch for the effects of heat illness: swelling, rash, cramps, fainting, heat exhaustion, heat stroke and the worsening of some health conditions.
“Seek a cool place such as a tree-shaded area, swimming pool, shower or bath, or air conditioned spot like a public building,” Environment Canada officials suggest. “Keep your house cool. Block the sun by closing curtains or blinds.”
Additionally, they say, never leave people or pets inside a parked vehicle in these weather conditions.
Heat illness symptoms include dizziness/fainting, nausea/vomiting, rapid breathing and heartbeat, extreme thirst and decreased urination with unusually dark urine.
