From Sunshine to Showers: The Soo’s Weekend Forecast Keeps You Guessing

Morning Chill, Afternoon Thaw — Then the Clouds and Rain Move In

Sault Ste. Marie, ON — April 11, 2025 – It’s a frosty but beautiful start to the day in Sault Ste. Marie, where as of 6:00 AM EDT, the temperature sits at -3.2°C with a noticeable wind chill of -7°C. Skies are mainly clear, and it’s shaping up to be a good-looking Friday. That said, don’t be fooled — spring’s got a few surprises lined up for the weekend.

Humidity is at a high 97%, making that cold morning air feel even crisper. Winds from the northwest at 11 km/h are keeping the chill in your cheeks, and visibility is excellent at 24 km, making it a bright and clear start over the St. Marys River.

Barometric pressure is currently at 102.4 kPa and falling, signaling a change in weather patterns that will start to take shape as we head into the weekend. For today though, mainly sunny skies will dominate once the sun rises higher, and we’re aiming for a high near 11°C. It’s a great day to get outside — just bring a jacket for the early morning hours.

Tonight will remain mainly clear, with clouds expected to build overnight. The temperature will dip to around -1°C, so while it’s a more comfortable spring night, that crisp edge is still hanging around.

The weekend brings increasing cloudiness on Saturday, with a growing chance of rain as the day goes on. Showers could arrive by Saturday afternoon or evening, and Sunday looks even wetter, with a higher likelihood of rain or even a few flurries mixing in overnight as cooler air returns.

Unfortunately, a full weekend forecast wasn’t available in this update, but based on surrounding systems in Northern Ontario, you can expect the Soo to see milder days around 8–10°C, followed by unsettled weather Saturday night into Monday, likely including some rain or wet snow — yes, spring can be dramatic like that.

Wardrobe-wise? Start with a warm jacket for the morning, and by the afternoon you can get away with a lighter layer. And keep the umbrella within reach — it’s going to come in handy before long.

On this day in history, Sault Ste. Marie has hit a record high of 20.3°C, while the record low sits at -14.5°C, proving that April in the Soo has always been a bit of a wildcard.

Trivia time: Did you know Sault Ste. Marie often experiences unique microclimates thanks to its location between Lake Superior and Lake Huron? This natural corridor channels moisture and wind, often making local forecasts just a touch more unpredictable than the rest of the province. Classic Soo.
