A long period of hot and humid weather kicked off Monday in southern Ontario, with daytime highs ranging from 30 to 36 C expected in various locations.
Environment Canada has issued yellow-level heat warnings for Windsor-Essex, Chatham-Kent, Sarnia-Lambton, and London, stating these will last through Friday and possibly extend into the weekend.
“Humidex values of 37 to 42 are expected today. Heat and humidity will ramp up further starting Tuesday with maximum temperatures between 31 to 36 degrees C and humidex values reaching 40 to 45. Minimum temperatures of 21 to 25 degrees C won’t provide much relief from the heat,” the federal weather agency noted.
Under Environment Canada’s color-coded warning system, yellow represents the lowest level, followed by orange, then red – which is the most severe warning.
The agency advised people to take steps to safeguard themselves and others, emphasizing that extreme heat can impact everyone’s health.
“Determine if you or those around you are at higher risk for heat illness. Check on older adults, those living alone, and other vulnerable individuals in person or via phone several times a day,” it stated.
Some locals and visitors who chatted with CBC Windsor mentioned they would be avoiding outdoor activities this week – including Canada Day events – opting instead for cooler indoor environments.
Berna Blondin shared that she works in Oakville but usually takes a week off to vacation in Windsor.
“You have to walk early in the morning [to beat the heat],” she advised.
“Later on if it reaches 39, 40, or even 42 … then stay indoors. Enjoy the AC.”
Her recommendation for those who must be outside or attending Canada Day celebrations is – “bring more water; don’t expose [yourself] to direct sunlight.”

Similar to Blondin’s approach, Linda Wasserlein plans ahead as well.
“I’m going to wake up really early and get my walking done as soon as I can. That’ll definitely be my plan this week,” she said.
“Normally we leave around 8:30 [or] 9 o’clock, but not this week. We’re heading out at about 7:30 [or] by latest at 8 o’clock.”
Joe Wells and Nicole Wells are visiting from Detroit and were out for their morning run.
“It’s been a bit warm,” Nicole remarked.
