Foggy Start, Cloudy Heart: Sault Ste. Marie’s Forecast Mixes It Up

Sault Ste. Marie, Ontario – April 24, 2025 – The Soo greets the day in stealth mode, cloaked in fog with a gentle breeze and a damp chill in the air. As of 6:00 AM at Sault Ste. Marie Airport, the temperature stands at 4.3°C with 100% humidity—yes, it’s a full-on fog spa out there. Winds are barely a whisper from the north at 2 km/h, and pressure is rising steadily at 102.1 kPa, hinting at improving conditions. Visibility is decent at 19 km, but don’t be fooled—those fog patches are hanging on for now.

Thursday Forecast: Fog Lifts, but Clouds Linger

Fog patches are expected to clear up by late this morning, giving way to a mix of sun and cloud. The wind will pick up out of the northwest around noon, reaching 20 km/h and helping to sweep the haze away. Temperatures will top out at 9°C—modest, but not miserable. With a UV index of 6 (that’s in the “don’t-forget-your-sunscreen” zone), any sunny breaks could still pack a little bite.

Thursday Night: Drizzle and Fog Return for a Nightcap

Tonight, skies turn mainly cloudy with a 40 percent chance of showers or light drizzle slipping in overnight. Fog patches will redevelop this evening, bringing visibility down again. Winds ease to calm later tonight, and the low settles at a cool +3°C. Not quite cold enough to see your breath, but definitely scarf-worthy.

Friday Forecast: A Full Rain Jacket Kind of Day

Friday brings the return of soggy skies with periods of rain expected through the day. Up to 15 mm could fall, so it’s a “bring out the rubber boots” kind of forecast. Morning fog will lift, but grey clouds will stick around. Winds shift to the north at 20 km/h by the afternoon, keeping things cool with a high of 9°C. The UV index drops to a low 1, so you can leave the sunglasses at home.

Friday night stays cloudy with a 30 percent chance of lingering showers. Temperatures will drop to a chilly +2°C.

The Weekend Forecast: From Grey to Glorious

Saturday, April 26: The sun returns in full force with clear skies and a high of 11°C. The perfect antidote to a damp week.

Saturday Night: Crisp and clear with the temperature dipping to zero. Break out the blankets for the fire pit!

Sunday, April 27: Another dose of sunshine with a high of 14°C. Spring might finally mean business. The evening sees just a few cloudy periods and a mild low of +4°C.

What to Wear in The Soo

Today’s damp and chilly start calls for layers. A water-resistant jacket will serve you well through tonight, especially with drizzle in the cards. Keep gloves handy for the morning commute, and wear shoes that won’t mind a surprise puddle. Sunglasses? Maybe. Umbrella? Definitely stash one for later.

Historical Highs and Lows
