Cold Winds Blow, But Milder Days are Lurking in the Forecast
Wind-Chilled Morning in The Soo, With Sunshine Leading the Charge Toward a Spring Awakening
Sault Ste. Marie, ON – Tuesday, April 8, 2025 – It’s a frosty start in Sault Ste. Marie this morning, with temperatures sitting at -11.8°C as of 6:00 AM EDT, under mainly clear skies. While the sun is already making its presence known, it hasn’t done much to warm things up—especially with a northwesterly breeze at 8 km/h pushing the wind chill down to -17°C. Barometric pressure is on the rise at 102.0 kPa, and humidity is at a moderate 66%, setting the stage for a crisp but stable weather day ahead.
The sunshine sticks around for most of the day, but don’t let it fool you—it’s going to be blustery. Winds are expected to pick up from the northwest, reaching 30 km/h and gusting up to 50 km/h this morning. The high will only manage -2°C, and that wind will keep it feeling closer to -8°C this afternoon, after a bitter wind chill low of -18°C earlier today. The UV index will hit 4, a moderate level, so if you’re outside enjoying the brightness, don’t skip the sunscreen—yes, even in April!
Tonight, conditions remain clear initially but will become partly cloudy overnight. Winds ease to 20 km/h before going calm later in the evening. Temperatures will drop to -15°C, and with that lingering breeze, the wind chill will hover near -20°C—so yes, it’s still flannel pajama and hot cocoa season in The Soo.
On Wednesday, April 9, a mix of sun and cloud is in the forecast, with lighter winds up to 15 km/h and a much-improved high of +3°C. Morning wind chills will still sting at around -17°C, but the afternoon should feel more comfortable, especially with that continued moderate UV index of 4. Wednesday night brings cloudy periods and a low of -5°C.
Thursday’s forecast continues the warming trend with a high of +5°C under partly sunny skies, and clear skies returning overnight with lows steady at -5°C. Friday brings full sunshine again, with another +5°C high and a low of -4°C—slowly but surely, spring is working its way in. By Saturday, it finally feels like we’re on the upswing, with sunny skies and a high of 8°C. Nighttime lows remain chilly at -2°C, but compared to this morning’s bone-chilling breeze, it’s practically balmy.
What to Wear:
This morning is all about full winter gear—insulated coat, gloves, toque, and wind-resistant everything. Those gusts will bite! As the week progresses, you can ease into lighter jackets and layers, but keep your scarf handy until at least Thursday. Sunglasses are a must under that spring sunshine.
On This Day in Weather History:
Sault Ste. Marie’s historical high for April 8 is a respectable 16.2°C, while the record low plunges to a frigid -21.5°C. So while today’s start is cold, it’s still far from the coldest April has to offer.
Weather Trivia Time!
Did you know? Sault Ste. Marie is one of the snowiest cities in Canada thanks to lake-effect snow from Lake Superior—but it also benefits from the lake moderating spring temperatures. That’s why even in early April, a few sunny days can make things feel significantly more springlike in a flash.
