A Cool Cruise Through April in the Soo – With a Few Surprise Flurries
Sault Ste. Marie is waking up under mostly cloudy skies this Saturday morning, and while it may be spring on the calendar, Old Man Winter is still loitering around the Great Lakes. At 7:00 AM at the Sault Ste. Marie Airport, the temperature was a chilly 1.0°C, with light northeast winds at just 5 km/h. The humidity sits at a slightly damp 79%, and barometric pressure is at 101.8 kPa but falling—so don’t be fooled by the calm start; the weather has some curveballs up its sleeve.
Saturday Forecast – From Cloudy to Windy with a Chance of Mischief
The Soo’s skies will remain mainly cloudy today, with a 40% chance of rain showers or flurries sneaking in late this afternoon. Winds will be picking up speed as the day progresses, shifting from gentle to gusty. By early afternoon, expect northwest winds at 30 km/h, gusting up to 50 km/h—definitely a “hold onto your hat” kind of afternoon. The temperature will peak at a modest 4°C, with a UV index of 5, which is considered moderate—so even with the cloud cover, a bit of sunscreen wouldn’t hurt if you’re out and about.
Tonight, skies clear slightly with partly cloudy conditions and a continued 40% chance of flurries early in the evening. Those brisk northwest winds stick around at 30 km/h gusting to 50, making the low of -7°C feel more like -13°C with the wind chill. Might be time to bring out the wool socks again.
Sunday & Monday – Sunshine Teases and Snowflakes Persist
Sunday starts with increasing cloudiness, and by late morning, there’s another 40% chance of flurries. Winds from the northwest at 20 km/h will gust to 40 in the afternoon. High temperatures only reach 2°C, and the morning wind chill will once again bite at -13°C—definitely not patio weather. The UV index remains moderate at 5, so the sun may make a few brief cameos between the flurries.
Sunday night brings cloudy periods and a 30% chance of—you guessed it—more flurries. Temperatures drop to a low of -6°C. Monday keeps the weather on its frosty path, with a mix of sun and cloud and a 40% chance of flurries continuing through the day. The high will hover around zero, with nighttime lows falling further to a crisp -11°C.
What to Wear in the Soo This Weekend
Layers, layers, and yes—more layers. You’ll need a solid spring jacket that isn’t afraid of snow, along with gloves and a hat, especially during those windy moments. If you’re out Sunday morning, don’t underestimate that -13 wind chill—bundle up accordingly. And with flurries lurking throughout the weekend, waterproof footwear is a smart move.
This Day in Sault Ste. Marie Weather History
April 5th has seen its fair share of drama in the Soo. The warmest recorded temperature on this date was a surprisingly balmy 19.4°C in 1991—a far cry from today’s high of 4°C. The coldest, meanwhile, dropped to a bone-chilling -21.7°C back in 1972. So while today feels chilly, history reminds us it could be way worse.
