Icy Start Gives Way to a Thaw in the 6ix
Toronto, ON – Sunday, March 30, 2025 – It’s a slick start to your Sunday as freezing rain gripped Toronto overnight, leaving a thin crust of ice on cars, sidewalks, and unsuspecting spring dreams. A Freezing Rain Warning remains in effect early this morning, but relief is on the way as temperatures nudge above the freezing mark.
Freezing Rain Tapering Off, Rain to Follow
At 6:15 AM, the mercury at Toronto Pearson International Airport was sitting just above freezing at 0.2°C, with mist hanging in the air and humidity at a saturated 100%. The barometric pressure is 101.5 kPa and falling, a clear sign the system is on the move. Winds are from the east-southeast at 8 km/h, but they’re expected to pick up through the day.
This morning, the freezing rain will transition to rain mixed with drizzle, making for a soggy start but at least sparing us any more icy build-up. Ice accretion of 3 to 5 mm may have already slicked up sidewalks, so be careful if you’re heading out early. East winds will increase to 20 km/h, gusting up to 40, pushing the daytime high up to +5°C. With a UV index of 1, it’s a low-risk day for sunburn but a high-risk one for slipping on sidewalks.
Tonight, the rain sticks around with a chance of thunderstorms creeping in late this evening and after midnight. Winds shift to the southwest at 30 km/h, gusting to 50, as temperatures hold steady at a mild +5°C overnight.
Spring Tease Monday, But Bundle Back Up After
Monday brings a temperature rollercoaster. The morning will stay damp with a 60 percent chance of showers, but the temperature will shoot up to a high of 15°C before tumbling back down to +3°C in the afternoon as winds swing to the northwest at 30 km/h, gusting to 50. Keep the raincoat handy, and maybe a scarf for later. Monday night will feature cloudy periods with a low of -4°C, a reminder that spring is still playing hard to get.
Tuesday finally offers a sunny reprieve, albeit a cool one, with a high of +3°C and a low of -3°C at night.
Wardrobe Woes & Wise Choices
Today calls for waterproof footwear with good grip—think traction over fashion. Layer up with something warm but flexible, as the temperature swings between icy and mild. An umbrella may seem optimistic but will serve you well later today when the drizzle turns to showers.
Historical Weather Snapshot
On this day in Toronto’s weather history, the record high was 21.4°C, a balmy blast from the past back in 1998. The coldest March 30th on record hit -14.4°C in 1923. Compared to those extremes, today’s weather is somewhere in the middle—mediocre, but manageable.
Toronto Weather Trivia
Did you know that Toronto averages just over 10 days of freezing rain per year? While today is nothing out of the ordinary for March, it’s a good reminder that spring in Ontario is more “boot season” than “flip-flop friendly”—at least for now.
