A Mild Midweek Forecast in the Big Smoke
TORONTO – April 23, 2025 – While Leafs Nation is still buzzing after a big win, the weather in Toronto is offering a quieter, gentler vibe to balance out the post-game high. As of 6:00 AM at Toronto Pearson International Airport, the temperature is a cool 5.9°C under partly cloudy skies. The wind is barely ruffling the flags, drifting in from the southeast at just 4 km/h. Humidity is sitting at a comfortable 71%, and the barometric pressure is at 102.3 kPa and rising—always a sign that fair weather is holding steady, at least for now.
The visibility is crystal clear at 24 kilometres, perfect for spotting celebratory parades—or, more realistically, dodging a few raindrops tonight. This afternoon brings a pleasant high of 16°C, though if you’re closer to the lakeshore, expect a cooler 10°C thanks to those waterborne breezes. The UV index is at 6, so while you may not be hitting the beach, a little sunscreen wouldn’t hurt if you’re basking in the post-playoff glow outdoors.
Tonight: Showers and Thunderstorm Risk Sneak In
As night falls, the clouds are planning a bit of a party themselves. Expect partly cloudy skies with a 30 percent chance of showers developing overnight and the added drama of a potential thunderstorm. The low will hover around a mild 9°C—so you won’t need the parka, but maybe keep the umbrella within arm’s reach.
Looking Ahead: Rollercoaster Temps and Spotty Showers
Thursday offers a blend of sun and cloud, much like today, with the same 30 percent chance of morning showers and the lingering risk of a thunderstorm. The high will spike to a very spring-like 20°C, making it a great day to trade in the hoodie for something a little lighter. Skies clear up at night with a low of 10°C.
Friday keeps us on our toes again with more sun-cloud mix and yet another 30 percent chance of showers, high of 17°C. By night, expect more definitive showers and a low of 8°C.
Saturday turns decidedly drearier, with a 70 percent chance of showers and a daytime high of 14°C. That system weakens slightly by Saturday night, offering cloudy periods with a 30 percent chance of lingering showers and a low around 4°C. Sunday looks like a return to the sun-cloud combo and another 30 percent chance of showers, with a decent high of 17°C and a mild night to follow.
What to Wear in the Six This Week
Today’s look? Think layers. A light jacket or hoodie will do for the cooler start, but by afternoon, you’ll want something that breathes. With showers looming tonight and into Thursday morning, make sure your outfit includes waterproof footwear—or at least a splash of good luck.
