Wind, Wet, and a Wee Bit of Sun for the Sault
SAULT STE. MARIE – WEATHER REPORT – May 23, 2025 – Pack your ponchos and brace for brisk breezes, Sault Ste. Marie! A series of soggy days lie ahead, courtesy of persistent showers and some good old-fashioned northwestern wind. While the city wakes up under light rain this Friday morning, the weekend promises a mixed bag—clouds, clearer spells, and the occasional peek at the sun.
As of 6:00 AM at Sault Ste. Marie Airport, the temperature is a cool 5.5°C, matching the dew point, meaning humidity is maxed out at 100%. Visibility sits at 16 km, so while your glasses might fog up, at least the horizon is still in sight. Winds are pushing in from the west-northwest at 15 km/h, but they’re expected to strengthen throughout the day. The barometric pressure is 101.3 kPa and falling, suggesting today’s showers aren’t in a hurry to leave.

What to Wear – Wind-Proof and Weather-Wise
It’s a trench coat and toque kind of weekend in the Soo. With gusty winds and chilly temps, layers are essential. A windbreaker or heavier jacket will serve you well today, especially if you’re walking near the waterfront. Waterproof footwear is a smart choice for Friday’s rain, while Saturday and Sunday invite a lighter jacket and maybe even sunglasses—just in case the sun gets bold.
Historic Highs and Lows – Soo Weather Time Capsule
On this date in Sault Ste. Marie’s weather history, the record high was 28.9°C, set in 1980—quite the contrast to today’s brisk conditions! Meanwhile, the chilliest May 23 on record dropped to a frosty -1.5°C back in 1963. So while we’re definitely on the cool side of spring today, we’ve dodged the historical extremes.
Weather Trivia – Lake Superior’s Influence
Did you know Lake Superior acts like a giant air conditioner for Sault Ste. Marie? The lake’s cold surface slows spring warming, making May often cooler and wetter than other parts of Ontario. It also fuels those famous Soo winds—so the next time your hat flies off downtown, you can thank the Big Lake!
