Winnipeg Weather Outlook – Monday, June 30, 2025
From Morning Mists to Afternoon Thunder? Keep an Eye on the Sky
Winnipeg is starting the final day of June with a sky full of mystery and a touch of mischief. At 6:00 AM, it’s 16.2°C under mostly cloudy skies, with humidity near saturation at 99%, giving that sticky-socks kind of feel. Winds from the west-northwest at 15 km/h are likely just the prelude to a breezier afternoon. The barometric pressure is 100.9 kPa and rising, so at least someone’s looking up.
This morning brings a few lingering showers to the region, but by midday we’ll see a mix of sun and cloud. Don’t put that umbrella too far though — there’s a 30% chance of additional showers, and the risk of a thunderstorm is on the cards this afternoon. Oh, and it’s going to get hazy — the kind that makes downtown buildings vanish into a summer shimmer.
By the numbers: a daytime high of 27°C, with a humidex of 31, and a UV index of 7, so both sunscreen and a wide-brimmed hat are good ideas.
Tonight – Calm After the Clatter?
The skies should settle somewhat this evening. Any lingering showers and the possibility of an early thunderstorm should clear out, taking the haze with them. Expect partly cloudy skies, a low of 16°C, and the northwest breeze at 30 km/h gusting to 50 should calm down as the evening progresses.
Canada Day Forecast – Tuesday, July 1, 2025
Mother Nature appears ready to wave a sunny flag for Canada’s big day! Clear skies and a warm high of 29°C will headline the day, with a humidex of 31 making it feel like a classic summer celebration. Winds will swing back from the northwest at 20 km/h, gusting to 40 near noon — perfect for keeping that maple leaf flag flying proudly.
There’s a slight catch after sunset — cloudy periods and a 60% chance of showers, so if you’re out for fireworks, pack a poncho just in case. Overnight low: 16°C.
Looking Ahead: Midweek Magic
Wednesday, July 2 promises another sun-filled stretch, with a high of 28°C and clear skies continuing overnight, dropping to a cool 12°C — practically perfect prairie weather.
What to Wear?
Think layers today — a light rain jacket in the morning, breathable clothing for the humid afternoon, and a hoodie or light sweater if you’re stargazing tonight. And always, don’t forget your sunscreen.
Manitoba Weather Trivia: Haze Before the Thunder
Did you know? Winnipeg’s summer haze can be caused by a combination of humidity, heat, and — occasionally — wildfire smoke drifting from distant regions. It often precedes atmospheric instability and thunderstorms. So if the air feels thick and visibility fades, the weather could be about to throw some sparks!
