From Sun to Snow in a Snap – Toronto’s Weather Keeps You Guessing
Toronto weather brings clear skies and cold today, with snow and rain arriving tonight. A milder Monday ahead with a chance of showers and flurries
Toronto, ON – Sunday, March 23, 2025 – Torontonians are waking up to a crisp, clear morning that feels every bit like winter’s last hurrah – but don’t get too cozy in your scarves. Spring has a few tricks up its sleeve this week, from sunshine to showers to a sudden dose of snow. It’s a classic case of March not quite making up its mind.
Today’s Weather – Clear Skies and a Light Chill
As of 5:00 AM EDT, it’s a brisk -7.2°C at Toronto Pearson International Airport, with a wind chill making it feel closer to -12. Winds are gently breezing in from the west-northwest at 9 km/h, and the barometric pressure is steady and rising at 102.3 kPa – a classic sign of clearing skies. Humidity sits at a moderate 68%, helping the chill feel just a little more pronounced.
Expect today to start off with plenty of sunshine, gradually giving way to cloud cover as the day progresses. Winds will pick up slightly to about 15 km/h, and the daytime high will nudge its way up to a modest +1°C. Don’t let that sunshine fool you early on – the wind chill this morning will make it feel like -10°C. The UV index is sitting at 4, which is moderate, so if you’re stepping out for a Sunday stroll, a bit of sunscreen wouldn’t hurt.
Tonight – Snow Becomes Rain as Temps Rise
The calm won’t last long – by evening, clouds will roll in and light snow will begin, transitioning into rain overnight as warmer air arrives. Expect 2 to 4 cm of snow before the changeover, driven in by southeast winds blowing at 30 km/h and gusting up to 50. Temperatures will rise from -1°C to a surprising +3°C by Monday morning – quite a leap in a single night!
Looking Ahead – A Slippery Mix for Monday and Tuesday
Monday will be mainly cloudy, with a 40% chance of showers. Winds will shift direction from southeast to southwest during the day, picking up to 30 km/h and gusting to 50. Highs will reach a milder 7°C, and the UV index drops just slightly to 3.
Monday night sees a return to colder air with a 40% chance of flurries or rain showers and a low of -3°C.
By Tuesday, the clouds stick around with a 30% chance of flurries or rain showers and a high of +2°C. The evening cools back down to -4°C with some lingering flurries under cloudy periods.
What to Wear – Layers Are Your Best Friend
If you’re heading out today, go for warm layers and a wind-resistant jacket – it may look sunny, but it feels like the Arctic. A hat and gloves are still essential in the early morning. As we head into tonight and Monday, keep the umbrella and waterproof footwear handy – wet slush is definitely on the way.
Historical Weather Fun Fact
On this date in Toronto weather history, the warmest March 23rd on record was a springlike 22.3°C back in 2012 – a true outlier! The coldest was a bone-chilling -20.0°C in 1874. Today’s weather sits snugly in the middle – a reminder that March doesn’t always play by the rules.
