From a Milder Sunday to a Snowy Tuesday – The Weather Keeps You Guessing!
Forecast for Sunday, April 13, 2025
Sault Ste. Marie is off to a mostly cloudy start this Sunday morning, with a temperature of 2.5°C as recorded at 7:00 AM EDT at the Sault Ste. Marie Airport. Winds are light out of the east at 9 km/h, and with humidity sitting at 61%, it feels fresh but not damp. The visibility is an impressive 32 kilometres—so no excuses for not seeing what’s coming. The barometric pressure is 101.6 kPa and falling, which usually signals incoming change—and in this case, a wet one.
Today’s weather is mostly cloudy with temperatures climbing to a mild high of 14°C. By late afternoon, expect winds to increase from the east to around 20 km/h. The UV index is a moderate 5, so if you’re getting out for some fresh air before the rain arrives, toss on some SPF and enjoy this rare April warmth while it lasts.
Tonight: Rain Moves In on a Gusty Southeast Wind
Tonight, skies remain cloudy, and there’s a 60% chance of showers developing late this evening and continuing overnight. Winds will strengthen from the southeast at 30 km/h, and the overnight low will hold steady around +3°C—chilly, but not frosty. You might want to park your umbrella near the door.
Monday, April 14: Mild Start, Wet Middle, Wild Finish
Monday will begin with rain, likely tapering off by noon, followed by mostly cloudy skies with a lingering 60% chance of scattered showers. The high will rise to a pleasant 12°C, and the UV index remains moderate at 4. Wind conditions, however, are taking a dramatic turn: morning breezes from the southeast at 20 km/h will go quiet briefly, then roar back in the afternoon from the northwest at 40 km/h gusting to 60. That’s enough to send hats flying and make trash cans dance.
As the day wraps up, skies remain cloudy into Monday night with a 70% chance of snow or drizzle. Yes, snow. Welcome to April in the Soo. It’ll remain windy through the night, with temperatures dipping to +1°C.
Tuesday & Wednesday: Back to the Snow Belt
Tuesday, April 15, brings periods of snow and continued windy conditions. The daytime high will reach only +3°C, and flurries may continue into the night with a low of -4°C. Definitely a boots-and-jacket kind of day.
Wednesday finally brings a break in the clouds with full sunshine and a high of +4°C—brisk, but bright. The night looks clear and cold, dipping down to -6°C. At this rate, spring is still pending approval.

Layer like you’re dressing for four seasons in one week—because you are. Light jackets for today and Monday, full waterproof gear for the rain, and winter wear (including toques and gloves) by Tuesday. Sunglasses will come in handy by midweek, as will a sturdy pair of boots.
