Spring Showers Meet a Cold Snap in Toronto’s Forecast

Toronto, ON – Monday, March 31, 2025 – If you stepped out this morning and wondered whether Mother Nature hit shuffle on the seasons, you’re not alone. At 6:00 AM, conditions at Toronto Pearson International Airport reported light rain and a humid 11°C, with an air so thick it’s practically hugging you.

The barometric pressure sits at 99.8 kPa and is falling, a telltale sign of changing weather.

Winds from the south-southwest are currently blowing at 13 km/h, and visibility remains clear at 24 km – enjoy the view while you can.

Today’s Forecast – Mild Morning, Icy Afternoon

Toronto is starting the day off damp with a 60% chance of showers tapering off early this afternoon. Fog patches, the sleepy remnants of overnight humidity, will lift as the day gets moving. The real shift comes with the wind – southwest breezes at 20 km/h gusting to 40 will whip around to become northwest by late morning, accelerating to 30 km/h with gusts reaching 50.

That wind will carry cooler air, pulling temperatures down to just +3°C by the afternoon. Better grab that raincoat and a windbreaker—you’ll need both.

While the UV index is a low 2 today, don’t forget the sunscreen if you’re out and about between cloud breaks. But more importantly, brace for the breeze – it’s a hat-losing kind of day.

Tonight and the Days Ahead – Cold Nights and a Brief Break in the Clouds

Tonight, skies remain overcast and the northwest winds will persist at 20 km/h, gusting up to 40. Temperatures will dip to a chilly -3°C, with a wind chill making it feel closer to -7. That cozy jacket? Definitely not time to pack it away yet.

Tuesday sees a welcome clearing in the morning, but it’ll still be brisk with a high of +4°C and a biting north wind gusting up to 40 km/h. Morning wind chills will feel as cold as -9, so layer up if you’re heading out early. The UV index rises to a moderate 5—sunshine at last, even if it’s not quite warm.

Tuesday night clouds over once again, with temperatures dropping back to -3°C. Then Wednesday brings a return of rain, with a daytime high of +5°C and nighttime showers keeping the air moist and the ground muddy. Low temperature Wednesday night is expected around 6°C.

Wardrobe Suggestion

Today calls for layers—start light but have that insulated outerwear ready for later. A raincoat with a hood is essential this morning, and gloves might not go amiss by evening. Don’t be fooled by the double-digit warmth at sunrise—it won’t last.
