A Chill Morning, a Snowy Evening – Classic Spring in The Soo

Sault Ste. Marie starts sunny and cold with snow arriving this afternoon and tonight. Up to 10 cm expected with gusty winds and chilly wind chills

Sault Ste. Marie, ON – Sunday, March 23, 2025 – This morning in The Soo starts off like the perfect winter postcard: crisp air, partly cloudy skies, and a wind chill that’ll nip your nose faster than a seagull snatching fries. But don’t get too attached to the peaceful start—March has plans, and those plans involve a healthy helping of snow and wind. Spring may be officially here, but winter’s not done playing yet.

Sunday Forecast – From Bright Skies to Flakes in the Air

At 5:00 AM EDT, conditions at Sault Ste. Marie Airport are partly cloudy with a temperature of -14.1°C. With an easterly breeze at 6 km/h, the wind chill sits at a brisk -18. Humidity is high at 92%, and barometric pressure is on the rise at 102.3 kPa—an early indicator of a system moving in.

Today’s forecast starts on a sunny note, but that won’t last long. Cloud cover will increase through the morning with a 40% chance of light snow developing late this afternoon. The wind will pick up noticeably, shifting to the southeast at 30 km/h and gusting up to 50, which will certainly put a brisk spin on things. Temperatures will climb to a high of -1°C, but with wind chills as low as -25°C early and around -8°C by afternoon, don’t ditch your parka just yet. UV index will reach a moderate 4, so sunglasses and a dab of sunscreen aren’t a bad idea.

Tonight – Snow Rolls In with Gusty East Winds

Tonight is all about snow—between 5 to 10 cm expected to fall across the region. Winds remain strong from the east at 30 km/h, keeping things gusty and cold. Temperatures will dip to -4°C overnight, with wind chills making it feel closer to -11°C. It’s a classic snow-globe evening in the Soo—just with more shoveling involved.

Monday and Tuesday – Snow, Flurries, and a Brief Calm

Monday continues the snowy theme, with another 2 to 4 cm expected. Winds will shift from northeast at 20 km/h in the morning to a breezy northwest 30 km/h by the afternoon. The daytime high hits 0°C, but that morning wind chill will make it feel closer to -10°C. The UV index drops to a low 1—no sunglasses required for this one.

Monday night stays cloudy with a 60% chance of flurries and a low of -7°C.

Tuesday brings more cloud cover and a 30% chance of flurries. The high will again sit at 0°C, and the night cools off to -12°C under partly cloudy skies. If you’re looking for signs of spring, this forecast is… not it.

What to Wear – Function Over Fashion (But You Can Still Slay)

Bundle up this morning with heavy winter layers and wind-resistant gear—you’ll need it to face the wind chill and gusts. A warm hat, gloves, and insulated boots are essential today and tonight, especially with snow and blowing winds. If you’re headed out Monday, waterproof outerwear is key, because this snow isn’t going to be the light, fluffy kind. It’s the “stick-to-everything” variety.

Historical Weather Nods – Soo’s Spring Surprises

On this day in Sault Ste. Marie’s weather history, the warmest March 23rd reached a mild 13.3°C back in 2012. The chilliest? A numbing -26.7°C in 1974. So while today may not feel balmy, it’s far from the coldest we’ve seen. Chalk it up to typical Northern Ontario spring roulette!
