A heat wave begins today (June 28) in southern Ontario including the Kawarthas — just in time for the real beginning of summer for kids, with today being the final day of classes for elementary school students and of exams for high school students.

Environment Canada has already issued a special weather statement to advise of an “extreme heat event” beginning on Saturday (June 30) and continuing through the Canada Day long weekend.

And today, Peterborough Public Health issued its first heat warning for the season.

Daytime highs this weekend are expected to reach the low to mid thirties with humidex values into the mid forties. Overnight low temperatures will only fall to the low twenties, providing little or no relief from the heat.

Beginning Saturday and continuing through the Canada Day long weekend, daytime highs are expected to reach the low to mid thirties with humidex values into the mid forties.

Overnight low temperatures will only fall to the low twenties, providing little or no relief from the heat.

It will start to heat up today and by Friday, when sunny skies return, temperatures will tip over 30°C. The heat will continue to climb on Saturday and Sunday.

The long-range forecast predicts the heat wave will continue for most if not all of next week, with temperatures remaining in the low thirties every day.
