The morning begins in Sault Ste. Marie with a crisp 7.1°C and skies that are mostly cloudy, setting the tone for a day where the sun might play a game of peek-a-boo. At 7:00 a.m. from the Sault Ste. Marie Airport, conditions were mostly dry, though not without the chance of moisture—there’s a 30 percent likelihood of showers late this morning and into the afternoon. The barometric pressure is sitting at 101.5 kPa and on a downward trend, suggesting the atmosphere isn’t done with its Tuesday theatrics.
Humidity is sitting at a comfortable 81%, enough to keep the air feeling fresh but not swampy. A gentle wind from the west-northwest is moving at 11 km/h, enough to rustle some leaves but unlikely to send your hat sailing into Lake Superior. Visibility is excellent at 32 km—clear enough to spot the next weather system sneaking in from the horizon.
Today’s high will climb to 15°C under mainly cloudy skies. While not a washout by any means, you may want to keep a small umbrella or rain jacket handy, especially if you’re planning a lunchtime stroll. The UV index reaches 5—moderate—so some sun protection isn’t a bad idea if those clouds part for a while.
Tonight, expect partly cloudy skies with another 30 percent chance of showers popping up before morning. Winds will pick up a bit, shifting to the northwest at 20 km/h late this evening, and the temperature will drop to a low of 5°C.
Wednesday starts off with clouds and a 30 percent chance of lingering showers in the early hours. However, skies will begin to clear in the afternoon as the northwest wind holds steady at 20 km/h. Temperatures will be a tad cooler with a high of 12°C, and the UV index ticks up to 7, considered high—so sunglasses and sunscreen may suddenly become relevant again.
Wednesday night takes a surprisingly chilly turn, with clear skies and the mercury falling to -2°C. A friendly reminder to tuck in those garden plants or toss a sheet over them unless you want a frosty surprise in the morning.
From there, the Soo shifts into a classic spring stride. Thursday is full-on sunshine with a high of 15°C, cooling to -1°C overnight. Friday continues the sunny streak with a high of 16°C and a milder night low of 6°C—perfect weather for patio plans and dog walks.
Dressing for the day? Think layers. Start with something warm and build up to something breathable by mid-afternoon. Keep a light jacket and maybe a foldable umbrella in your bag, just in case the sky decides to surprise you.
On this date in Sault Ste. Marie weather history, the warmest May 6 ever recorded was a delightful 28.3°C in 1955, while the coldest dropped to a teeth-chattering -5.1°C in 1967. So today’s middle-ground temperatures are downright pleasant by comparison.
