Warm Weather Rolls In With Sunshine, Haze, and Temperatures Touching 30°C
A Mild and Hazy Morning Start
Winnipeg, MB – Wednesday, May 28, 2025: The city is waking up to a warm spring morning with temperatures already sitting at 11.8°C by 4:00 AM, as recorded at Winnipeg Richardson International Airport. Skies are mostly cloudy, though visibility is strong at 24 km and the morning haze adds a golden tint to the landscape. The humidity is at 65%, with a dew point of 5.5°C, and a light southwest wind at 5 km/h gently stirs the early morning air. Pressure is at 102.2 kPa and rising, signalling stable conditions despite the slightly smoky skies.
Highs Near 30°C with Haze and Sunshine on the Menu
Today’s forecast calls for a mix of sun and cloud, with hazy conditions persisting throughout the day — likely due to smoke from distant wildfires. That haze may soften the sun’s intensity visually, but don’t be fooled: the UV index is a strong 7, considered high, so sun protection is still essential if you’re spending any time outdoors.
The high will reach a balmy 27°C, marking one of the hottest days so far this season. It’s a taste of summer in the air — one that’s here to stay for a few more days.
Warm and Clear Tonight
Tonight, skies will turn clear, though the haze will remain. Expect a low of 14°C, which is warm for a spring night in Winnipeg — ideal for late patio dinners or a sunset bike ride.
Heat Builds Toward Thursday and Friday
Thursday brings full sunshine and hazy skies, with temperatures rising to a hot 30°C. Winds will pick up slightly, becoming westerly at 20 km/h, offering a bit of relief from the heat. The UV index climbs to 8, which is very high, so keep the sunscreen and hydration flowing. Thursday night stays clear and warm with a low of 17°C.
Friday looks much the same: sunny and hot with a high of 30°C and a clear night at 15°C.
A Slight Dip Saturday – But Still Sunny
By Saturday, temperatures dip slightly — if you can call 26°C a dip — with more sunshine and another clear night forecasted. The long stretch of fair weather is perfect for outdoor plans, gardening, or just catching up on your vitamin D after a long Prairie winter.
What to Wear?
With mornings now mild and afternoons blazing, it’s shorts-and-sunglasses season in full force. Pack light layers if you’re heading out early, but be ready for mid-summer heat by noon. With haze in the air, those sensitive to poor air quality might want to take it easy during peak heat hours.
Historic Temperatures for May 28
On this day in Winnipeg’s weather history, the record high reached 32.8°C, and the record low dipped to -1.7°C. Today’s 27°C high doesn’t quite hit record territory, but it’s comfortably on the hot side of normal — and we’re inching ever closer to official beach weather.
