Eastern Canada is bracing for its first heat wave of Summer 2025, with temperatures expected to reach the mid-30s and humidity making it feel even hotter, signaling a “torrid summer” ahead, according to Environment Canada’s David Phillips. This heat, driven by a “Bermuda High,” will lead to oppressive conditions, particularly with a wet spring compounding the humidity, and is likely to repeat throughout the summer, necessitating precautions against heat-related illnesses.
