Sunny Skies Today, But Don’t Ditch the Jacket Just Yet
Toronto, ON – Friday, March 21, 2025 – March in Toronto continues its classic will-it-or-won’t-it dance with spring, offering up a sunny start to the weekend, tempered by brisk winds and cooler morning temps. As of 6:00 AM EDT at Toronto Pearson International Airport, the temperature sits at a chilly -2.6°C, with a west wind blowing at 14 km/h and a wind chill of -7. Humidity stands at 73%, and the barometric pressure is at 101.4 kPa and rising — a good sign for today’s sunshine holding strong.
Today’s forecast promises plenty of sunshine with winds shifting to the southwest and picking up speed — 30 km/h with gusts reaching up to 50 km/h later this morning. The high will climb to a very respectable 9°C, though the morning hours will feel like -8°C with the wind chill. A moderate UV index of 4 means you might want to toss some sunscreen on your nose if you’re spending time outdoors.
Tonight, things take a turn toward the unpredictable. Clear skies will begin to cloud over after midnight, and there’s a 40% chance of showers overnight. The wind doesn’t plan to settle down either, staying strong from the southwest at 30 km/h, still gusting to 50. The low overnight will remain above freezing at +5°C, so no need to bring in the garden gnomes just yet.
Weekend Forecast – Flurries, Rain, and Sun Swapping Shifts
Saturday, March 22nd starts with a grab bag of precipitation. A few morning rain showers or flurries will make a quick appearance, then retreat, leaving behind mostly cloudy skies with a lingering 30% chance of flurries. The wind will swing around from the northwest, gusting up to 50 km/h again. Expect temperatures to tumble as the day progresses, falling to zero in the afternoon. The UV index dips slightly to 3, still moderate.
Saturday night brings clearing skies and a significant drop in temperature — the mercury slides to -8°C, so winter isn’t quite out the door yet.
By Sunday, March 23rd, Toronto sees a return to sunshine, though temperatures will remain modest with a high of +1°C. But don’t get too cozy — periods of snow or rain are expected to sneak in after dark, with a low near +1°C.

What to Wear – Layers, Lids, and Maybe a Windbreaker Ballet
Today is one of those “dress for two seasons” kind of days. Mornings call for a warm coat, scarf, and gloves to tackle that wind chill. But by midday, when the sun warms things up to 9°C, you’ll want to shed a layer or two — just don’t get too ambitious with shorts just yet. A sturdy windbreaker is your best friend through this gusty stretch, and you might want to keep an umbrella on standby Saturday night into Sunday.
