Winnipeg Weather Forecast – A Perfect Prairie Stretch of Sun, Calm Winds, and Classic Spring Charm
Clear Skies and Calm Breezes to Start the Day
Winnipeg, MB – Thursday, May 22, 2025: The early bird gets a dose of prairie perfection this morning as the city wakes up under clear skies and a calm, crisp atmosphere. At 4:00 AM, the temperature at Winnipeg Richardson International Airport is 7.1°C, with humidity at 55% and a light east wind at 4 km/h. The air is fresh and dry, thanks to a dew point of -1.4°C, and the barometric pressure sits at a stable 102.1 kPa and rising, which bodes well for the sunny stretch ahead.
Sunshine Galore and a Gentle Northeast Breeze
Today is shaping up to be a sun-splashed stunner. Expect full-on sunshine with a high reaching 20°C, the kind of warmth that teases summer while still feeling perfectly spring. Winds will pick up slightly, becoming northeast at 20 km/h early this afternoon, but it’ll remain comfortable with a high UV index of 7, so break out the SPF if you’re heading outdoors — and let’s be honest, why wouldn’t you?
A Chilly But Clear Night with Frost Risk
Tonight, skies stay clear, with that northeast wind becoming light late this evening. The overnight low dips to +3°C, and there’s a risk of frost, especially in outlying areas. So, prairie gardeners, don’t let the sun fool you — cover your seedlings or bring in the planters just to be safe.
Warm, Sunny Days Stretch Into the Weekend
Friday continues the fair-weather theme with mainly sunny skies and a high of 20°C. It’ll be another gorgeous day under a UV index of 7, and clear skies return Friday night, with a low of +5°C, making for perfect evening walks or backyard stargazing.
Saturday brings more sunshine and a high of 21°C, and though Saturday night cools off to +2°C, it’s still in the frost-safe zone. The sunny streak continues into Sunday, where we top out at a delightful 23°C. The overnight low of 7°C Sunday night means you can leave the extra blanket in the closet.
What to Wear?
We’re talking sunglasses, sunscreen, and layers! Mornings are still on the chilly side, so keep a light jacket or hoodie handy, but you’ll want to shed it by mid-day. With UV levels ramping up, protect your skin and lips even if it doesn’t feel hot. A hat and water bottle wouldn’t hurt either.
Historic Temperatures for May 22
Winnipeg’s history book for May 22 includes a record high of 33.3°C, so if it feels like spring is holding back a little, it’s still got plenty of potential. The record low for this day is -3.9°C, which makes tonight’s +3°C feel downright generous.
Winnipeg Weather Trivia
Did you know Winnipeg averages over 2,300 hours of sunshine per year? That makes it one of Canada’s sunniest major cities. No wonder locals are such pros at barbecuing, biking, and backyard relaxing — and this weekend will offer the perfect weather for all three!
