Cloudy Skies Over Pearson as Spring Tries to Warm Up
Toronto, ON – The city wakes up this Saturday to a cool and damp morning, with temperatures sitting at 2.8°C and a heavy dose of humidity (97%) in the air, thanks to a mostly cloudy sky and light north winds at 10 km/h. Observations from Toronto Pearson International Airport at 6:00 AM EDT show stable but unsettled conditions, with a pressure reading of 102.1 kPa and falling — a signal that change is coming, as always, in layers.
Saturday: Damp Start, Cloudy Finish
There’s a 40% chance of drizzle lingering through the early hours, so if you’re out walking the dog or grabbing coffee, it’s wise to bring a hood or small umbrella — not quite a downpour, but certainly enough to frizz your hair.
Despite the murky start, the high will climb to 11°C under generally cloudy skies. Winds stay light throughout the day, and visibility is excellent at 24 km, should you be venturing beyond the city for a spring drive.
The UV index will hit 3, which is considered moderate — not beach weather by any stretch, but if you’re catching some rays during breaks in the cloud, a little sunscreen won’t hurt.
Tonight and Sunday: Fog Rolls In, Sun Returns
Tonight brings a slight shift as skies become partly cloudy late in the evening. Fog patches are expected to develop after midnight, especially in outlying areas and around the lakefront. The low will settle around +1°C, making it a cool but calm evening across the GTA.
Sunday, April 13, shapes up to be a beauty — once the fog clears. Expect a mix of sun and cloud in the early morning, followed by mainly sunny skies. The high will reach a comfortable 13°C, and the UV index rises to 5, a reminder that spring sun is stronger than you think.
By Sunday night, skies cloud up again and temperatures remain mild, with a low of 6°C.
Monday and Beyond: Warming Up Before a Sudden Chill
Monday, April 14, keeps up the pleasant trend, with a mix of sun and cloud, a high of 16°C, and a 40% chance of showers in the afternoon. Spring will feel almost convincing!
But don’t stash the winterwear just yet. On Tuesday, April 15, a cool front brings cloudy skies and a 40% chance of rain showers or flurries. The high will only reach 7°C, and Tuesday night dips to -1°C, with a 30% chance of flurries. Yes, in April. Welcome to Southern Ontario.
Weather History for April 12 in Toronto
Historically, Toronto has hit a record high of 25.0°C on April 12 — now that’s a spring scorcher! The record low, though, reminds us where we came from: -7.2°C. Today’s 3°C start lands us comfortably in the middle of that very Toronto-style weather tug-of-war.
What to Wear in the 6ix?
For today: light coat, waterproof shoes, and something warm enough for the damp morning air. Sunday’s sunshine will let you swap the coat for a hoodie, and by Monday, sunglasses and an umbrella might be your best combo. But on Tuesday — maybe keep the gloves handy.
TDot Trivia: Fog on the Frontlines
Did you know? Toronto’s waterfront fog is often caused by cold lake air mixing with urban warmth — creating what pilots call “inversion fog.” Translation: your CN Tower view may be missing a few floors today!
