Today’s Forecast for Sault Ste. Marie
Good morning Sault Ste. Marie! As of 7:00 AM EDT, it’s a downright balmy start to your Tuesday with a temperature of 12.3°C at the airport. It’s mostly cloudy, giving the sky that soft, filtered look that makes everything feel a bit dreamy.
This is quite the contrast to Thunder Bay at the other end of Lake Superior where it is -6°C this morning with a brisk north wind.
With a dew point matching the air temperature at 12.3°C, humidity is at a maxed-out 100% — it’s practically a springtime sauna out there! Winds are gentle from the southeast at 6 km/h, and visibility is clear up to 16 kilometres. The barometric pressure sits at 100.0 kPa but is falling, hinting that some weather changes could be on the horizon.
Today’s high holds steady around 12°C under mostly cloudy skies. It’s warm but with that heavy, muggy feel that could have you peeling off layers even without direct sunshine. There’s a softness in the air that suggests rain could pop up later, even though no immediate showers are yet in the forecast from Environment Canada’s morning update.
Tonight and Tomorrow: Clouds Continue to Linger
Tonight, expect the cloudy skies to hang around. The mild springtime air continues, though specific nighttime temperatures haven’t been updated for Sault Ste. Marie just yet this morning — but based on trends, it should stay comfortably above freezing.
Wednesday, April 30th, is expected to mirror today’s warmth but bring more organized rain chances across much of Northern Ontario, so don’t leave home without an umbrella. Winds are likely to pick up slightly as a low-pressure system moves through.
Historic Highs and Lows for April 29
On this date, Sault Ste. Marie has experienced a historic high of 27.8°C back in 1952 — now that’s a real taste of early summer! The record low for April 29th sits at a crisp -6.1°C, recorded in 1967. Compared to either extreme, today’s 12°C feels like a comfortable middle ground.
What to Wear?
Today is all about flexibility! Light, breathable clothing is your best choice — think t-shirts or thin long sleeves — but maybe toss a light jacket in your bag in case the breeze picks up or a shower surprises you. Waterproof footwear might not be a bad idea either with the humidity hinting at unsettled conditions.
