Windchill Could Feel Like -25°C in the GTA This Weekend

Get ready to bundle up, as an arctic blast is set to sweep across southern Ontario, plunging temperatures to frigid lows this weekend. Wind chill values are expected to make it feel as cold as -25°C in the Greater Toronto Area (GTA) and beyond, marking a sharp contrast from the milder weather earlier this week.

According to Environment and Climate Change Canada (ECCC), temperatures reached a mild 6°C on Tuesday at Toronto Pearson Airport. However, a cold front moving in will bring drastically colder conditions starting Wednesday, with snow and highs of 3°C. By Thursday and Friday, daytime highs will hover around the freezing mark, while nighttime temperatures could drop to -10°C in Mississauga, Brampton, Durham Region, Burlington, and Oakville.

“Very cold wind chill values are expected this weekend to kick start the holiday season,” ECCC shared on X (formerly Twitter). “Much of southern Ontario could feel like -20°C on Saturday morning and -25°C on Sunday morning. Remember to cover up and dress warmly if you will be out and about!”

Saturday morning will see temperatures dip to -11°C, but the wind chill will make it feel closer to -18°C. The afternoon may bring some relief at -8°C, though the evening could plunge to -15°C, feeling like a bone-chilling -26°C.

Sunday offers no reprieve, with daytime highs of -7°C and wind chill values between -22°C and -25°C. Residents are advised to limit outdoor exposure, dress in layers, and cover exposed skin to avoid frostbite.
