A Damp Start to Friday in the Soo
SAULT STE. MARIE – WEATHER – Good morning from the Soo, where spring is serving up a classic combo of cool air and moisture. As of 6:00 AM at the Sault Ste. Marie Airport, we’re sitting at 3.0°C with air so thick you could stir it — humidity is at a soggy 100%. Winds are barely whispering from the east at 4 km/h, and visibility stretches out to a clear 24 km despite the fog patches lingering early this morning. The barometric pressure is holding at 102.3 kPa, but with a falling trend, it’s a sign the sky is cooking up something.
Periods of rain will settle in early today, with 5 to 10 mm of precipitation expected to fall gently (or persistently) from above. Fog patches should lift by late morning, clearing the way for an overcast but manageable afternoon. Today’s high climbs to a modest 9°C — not balmy, but enough to melt the last stubborn snowbanks. The UV index is low at 1, so no sunscreen stress today.
Tonight: Raindrops Keep Falling, Winds Begin to Whip
Tonight stays damp with continued periods of rain dropping another 5 to 10 mm into the mix. As we move into the later evening hours, winds will shift to the northwest and pick up to 20 km/h. Temperatures will ease down to a low of +2°C — mild enough to keep things wet but not icy. A good night for something warm on the stove and a sturdy roof over your head.
Saturday: Rain Fades, Sun Breaks Through
Saturday starts wet with rain lingering through the morning, but then the clouds will loosen their grip. By midday, expect a mix of sun and cloud to break through, offering a refreshing reset to the skies. The wind will be a bit punchy out of the northwest at 20 km/h, gusting up to 40, so brace for a breezy afternoon. The high will reach 10°C, and the UV index climbs to a moderate 5 — a reminder that, yes, sunshine does still exist in April.
Skies will clear beautifully Saturday night, and things get a little crisp with an overnight low of zero. It’s a good evening to test out that transitional jacket and maybe crank the thermostat one last time.
Looking Ahead: A Warming Trend with a Side of Showers
Sunday turns cloudy again with a slightly warmer high of 12°C. It’s the kind of day that whispers of spring without shouting about it. Sunday night stays on the mild side too, with cloudy skies and a low of +3°C.
Monday, though, brings the heat (relatively speaking). A mix of sun and cloud pushes the high to 18°C — practically patio weather! There’s a 40 percent chance of showers during the day, and by nightfall, that chance increases to 70 percent with a low of 10°C. A great excuse to plan something outdoors while keeping your umbrella on speed dial.
What to Wear in the Soo Today
Rain gear is your best friend. Grab that waterproof jacket and some decent boots — and don’t forget something cozy underneath. With temps hanging in the single digits and full saturation in the air, it’s the kind of day that begs for layers.
Today in Weather History
On April 25th, Sault Ste. Marie once reached a warm 25.0°C in 1990, reminding us that heatwaves can happen this time of year. The chilliest this day ever got? -8.5°C in 1972. If nothing else, Sudbury and the Soo sure know how to keep April unpredictable.
Weather Trivia: The Foggy City
Did you know that Sault Ste. Marie often sees some of the densest fog in Ontario thanks to the collision of moist lake air and cool spring mornings? It’s not your imagination — fog season is real here.
