SAULT STE. MARIE – May 2, 2025 – Sault Ste. Marie greets Friday with a cool, cloud-covered sky and just enough dampness in the air to make you second-guess skipping the jacket. As of 6:00 AM at the Sault Ste. Marie Airport, it’s 4.8°C with 95% humidity—just enough to make the air feel a little thicker than you’d like. A light northwest breeze is nudging along at 3 km/h for now, but stronger winds are waiting in the wings. Visibility is crystal clear at 32 km, and the barometric pressure is at 100.5 kPa and rising, hinting at improving conditions ahead.
Today’s forecast stays on the cooler and greyer side of spring. Expect a cloudy day with a 40 percent chance of showers—light jacket weather with a side of uncertainty. Winds will pick up from the northwest by this afternoon, reaching 20 km/h and bringing a touch of bite to the air. The temperature will top out at just 7°C, so if you’re heading out, be prepared for a day that feels more like early April than May. The UV index will reach a moderate 4—low enough to go without sunscreen for most, but not low enough to totally ignore.
Historically, the Sault has seen some interesting temperature swings on May 2. The record high was a balmy 26.1°C set back in 2001, while the record low plummeted to -6.7°C in 1975. Compared to those extremes, today’s forecast sits somewhere in the middle—a little dreary, but not dramatic.
Tonight brings a bit of a chill. The skies will remain mostly cloudy until after midnight, when things begin to clear up. Winds from the northwest at 20 km/h will calm down and become light later this evening. Temperatures will drop below freezing to a low of -1°C, so you’ll want that heavier coat if you’re planning to be out late.
Saturday offers a refreshing turnaround. The day begins with a mix of sun and cloud, clearing by late morning, and warming up to a much more comfortable high of 13°C. The UV index rises to 6, so a little sunscreen might be in order if you’re outdoors for long. The skies stay clear Saturday night with a mild low of 4°C.
Sunday brings a full dose of sunshine and an even warmer high of 17°C—a perfect spring day for anything outdoors. Sunday night remains clear with temperatures dipping to a pleasant 5°C.
By Monday, the pattern continues with a mix of sun and cloud and a high of 16°C. Some cloudy periods move in overnight, with a low of 6°C. All signs are pointing to a solid stretch of spring weather—finally.
Today’s attire should lean on the warmer side: think waterproof jacket, warm layers, and gloves wouldn’t be overkill for the evening. You might dodge the rain, but the chill will definitely stick around long enough to be noticed.
Here’s a fun Sault Ste. Marie weather tidbit: the city’s location between Lake Superior and Lake Huron gives it some serious weather mood swings. The surrounding Great Lakes often play tug-of-war with air masses, making cloudy days and rapid shifts in wind patterns a regular feature here—something you can count on, even if you can’t always count on the sun.
