Sault Ste. Marie Weather Forecast – April 7, 2025
Winter’s back for one last dramatic entrance, and this time it’s taking centre stage in Sault Ste. Marie. A Winter Weather Travel Advisory is in effect this morning for Sault Ste. Marie and St. Joseph Island, as a potent system delivers bursts of snow and some very unpleasant driving conditions. If you thought spring was finally here to stay—today’s weather is here to remind you who’s still in charge.
As of 7:00 AM EDT at the Sault Ste. Marie Airport, the temperature is -2.5°C with light snow falling and only 2 km visibility. Wind is gusting out of the north-northeast at 26 km/h, peaking at 36 km/h, making it feel more like -9°C. Humidity is high at 89%, and barometric pressure is falling at 100.9 kPa—classic signs of an active system still moving through.
Morning Snow and Blowing Drifts—Drive Safe Out There!
Snowfall is expected to continue through the morning, with peak snowfall rates of 2 to 4 cm per hour, and total accumulation between 10 and 15 cm. Gusty winds—up to 60 km/h by early afternoon—are causing areas of local blowing snow, reducing visibility and making travel tricky. If you’re out on the roads this morning, take it slow and give yourself lots of space.
By late morning, snow will taper off from west to east, leaving behind cloudy skies with a 30 percent chance of lingering flurries. The high today is -3°C, but wind chills will hover near -14°C, thanks to northwest winds gusting to 60 km/h. The UV index will climb to a moderate 4—if you do catch a glimpse of the sun through the snow, your sunglasses might still come in handy.
Tonight Clears, But the Cold Tightens Its Grip
As the snow exits the scene, skies will clear tonight, but cold air rushes in behind the system. Expect northwest winds to persist at 30 km/h gusting to 50 before finally easing near midnight. The low will drop to -14°C, and with wind chills near -22 overnight, it’s another night for those thermal pajamas and maybe even an extra blanket.
Spring Sunshine Slowly Fights Back
Tuesday, April 8, will be sunny, though still blustery with northwest winds kicking up again to 30 km/h by late morning. The high will reach -2°C, but morning wind chills near -20°C are no joke—there’s even a continued risk of frostbite. Clear skies continue Tuesday night with a low of -11°C.
By Wednesday, the sun remains and temperatures take a small but promising leap forward, reaching +3°C. Thursday keeps the sunny streak alive with a high of 6°C. Nights remain chilly, dipping below freezing, but spring is trying to break through.
What to Wear
Today is all about bundling up. Winter coats, scarves, gloves, and windproof gear are non-negotiables. If you’re walking or commuting, be sure to wear sturdy boots and keep your face covered—it’s not just cold, it’s wind-whipping cold.
April 7th in Sault Ste. Marie’s Weather History
The record high for this day was a pleasant 17.8°C—hard to imagine while shovelling a foot of snow. On the flip side, the record low for April 7 dipped to a chilly -21.1°C. Today sits comfortably in between, but the snowfall is what’s stealing the spotlight.
Weather Trivia: Lake Superior’s Snow Machine
Did you know Lake Superior is the largest freshwater lake by surface area in the world? It also turns Sault Ste. Marie into a snow trap every spring. When cold air moves in from the north and hits that lake moisture, it often fuels intense snow squalls—just like we’re seeing today.
