From Sunny Skies to Soggy Days: A Classic Soo Spring Swing
SAULT STE. MARIE – WEATHER REPORT – Sault Ste. Marie is enjoying a pleasant start to Tuesday with mild temperatures and mostly sunny skies.

Soo Style Tips for the Changing Skies
Today is ideal for short sleeves, light jackets, and soaking up the outdoors, but pack that umbrella and raincoat for the rest of the week. Foggy mornings midweek will make for tricky commutes, so take extra caution. And with UV levels still high despite the clouds, don’t get tricked into thinking the sun’s not working hard behind those clouds.

Soo Weather Trivia
Did you know? Sault Ste. Marie’s position between Lake Superior and Lake Huron often creates its own microclimate—fog and drizzle can hang around longer than expected, especially when warm, moist air rides over those cool spring waters. Locals call it “Soo Soup” when the city feels trapped under a blanket of fog and drizzle—something we may see later this week!
