Weather in Toronto: Cloud Charisma with a Side of Thunder

Toronto, Ontario – April 24, 2025 – The city wakes up under mostly cloudy skies this morning, already teasing us with warmer temperatures that hint at a dramatic shift. As of 6:00 AM at Toronto Pearson International Airport, it’s a modest 9°C, with a light northern breeze whispering through at just 2 km/h. Pressure stands at 102.3 kPa and is slowly falling, hinting that changes are indeed in the air. Humidity is a comfortable 57%, not quite muggy, not quite dry—Toronto is walking the weather tightrope.

Afternoon Antics: Will It Rain or Will It Shine?

Sun-lovers, take a deep breath—Toronto is offering a bit of both today. Expect clear skies early this morning, giving way to a mix of sun and clouds. But don’t get too cozy: there’s a 30 percent chance of showers by this afternoon, with a side of potential thunderstorms just to keep things spicy. Temperatures will climb to a generous 23°C, although lakeside folks will only reach 18°C thanks to our ever-chilly friend Lake Ontario. The humidex will make it feel like 26°C, so you might just break a sweat on your lunch break walk. The UV index is a “high” 6—sunscreen and stylish shades are your go-to accessories.

Evening Outlook: Thunderclaps and Gusty Guests

Tonight, the weather flirts with drama. Skies remain partly cloudy, and there’s still a 30 percent chance of showers early in the evening and again before dawn. Thunderstorms may crash the party early on, so if you’re heading out, pack an umbrella and maybe a backup outfit. Winds will shift eastward and pick up speed, reaching 20 km/h and gusting to 40 km/h before morning. The overnight low will settle around 10°C—a bit cool, but certainly not coat-worthy.

Looking Ahead: From Murky to Marvelous

Friday, April 25: The grey theme continues with mainly cloudy skies and a 40 percent chance of showers. Thunderstorms might drop by again in the afternoon. Winds will stay strong from the east at 20 km/h, gusting to 40. Expect a daytime high of 14°C, with a UV index again at a high 6. By nightfall, showers are forecast and the mercury dips to 8°C.

Saturday, April 26: A quieter vibe returns with cloudy skies and just a 30 percent chance of showers. The high will be a mild 13°C. But by Saturday night, the skies clear up and temperatures fall to a crisp +3°C—hello, stargazing weather!

Sunday, April 27: Sunshine finally takes the lead with clear skies and a high of 17°C. The night will remain clear with a gentle low of +5°C—perfect for an evening patio session.

Wardrobe Wizardry

Today calls for a bit of everything—think layering. A light, breathable jacket over a tee should do the trick. Keep a small umbrella stashed in your bag and swap the sneakers for waterproof shoes just in case. And don’t forget those sunglasses—yes, even when it’s cloudy!

Historic Weather Note

On this date, Toronto’s historical high reached a sizzling 29.1°C, set back in 1990. The chilliest it’s ever been on April 24? A frosty -4.4°C in 1965. So, today’s forecast is a comfy compromise!
