Cloudy Start, Rainy Middle, and Snowy Surprise
SUDBURY – WEATHER – Greater Sudbury greets Friday with a chilly 3.1°C and a sky full of cloud cover that seems to be pondering whether to cry — and it just might. Humidity is nearly maxed out at a damp 97%, so your hair may have already called it a day. The wind is drifting in from the northeast at 20 km/h, adding a brisk bite to the morning. Visibility is a crystal-clear 32 km, which is great news for commuters navigating the early fog patches — which are expected to lift by mid-morning.
The barometric pressure sits at 102.5 kPa, though it’s beginning to fall — a subtle cue from the atmosphere that change is on the way. That change begins today with a 40 percent chance of showers this morning, giving way to more committed periods of rain near noon. We can expect around 5 mm of precipitation, and while the high will only reach 8°C, it’s enough to keep the snow away — at least for now. Winds will calm down as the morning progresses, offering a brief window of relative calm before things stir up again later. The UV index sits at a moderate 4, so a bit of sunscreen wouldn’t hurt if the clouds crack a smile.
Tonight: A Slushy Spring Mix in Store
As we slide into the evening hours, rain will continue — and here’s the kicker — it’s going to start mixing with wet snow overnight. Yes, we’re on that classic Northern Ontario spring seesaw. Expect 10 to 15 mm of rainfall overall, and keep an eye out for slushy patches if you’re out late. Winds will pick up again, shifting to the north at 20 km/h and gusting to 40, while the mercury dips to a low of just +1°C. A night for the kettle and cozy socks, no doubt.
Saturday Brings a Wild Weather Combo
Saturday keeps things interesting with more periods of rain or wet snow lingering into the afternoon. Once those end, we’ll get a mix of sun and cloud, a fitting metaphor for Sudbury’s indecisive spring. Expect another 5 mm of precipitation. The wind ramps up again from the north, gusting up to 50 km/h — so if you’re stepping out, make sure your hat’s got a chin strap. The high will reach 7°C, and the UV index holds at a moderate 3.
As the day winds down, the weather settles — finally. Skies clear Saturday night and temperatures level off around +1°C, just enough to keep the roads from icing up.
Sunday & Monday: A Taste of the Season We’ve Been Waiting For
Good news on the horizon: Sunday looks gorgeous. Sunshine will flood the region with a high of 16°C — a dramatic shift that may have you eyeing the barbecue. Sunday night stays calm with just a few cloudy periods and a low of +5°C.
Monday continues the trend with a mix of sun and cloud and a 30 percent chance of showers. The high will climb to 14°C. Monday night turns wetter, though, with a 70 percent chance of rain and a low of 9°C — so keep your umbrella close.
What to Wear in Sudbury Today
Layers are key. Start with a warm base, add a waterproof jacket, and don’t forget something wind-resistant — those gusts have plans. Footwear should be ready for puddles, and if you’re heading out tonight, bring something warmer — and maybe a shovel, just in case.
Today in Sudbury’s Weather History
On this date, Sudbury’s warmest April 25th saw a high of 25.0°C in 1990, while the record low bottomed out at a frigid -10.0°C back in 1972. Spring, it seems, has always had a split personality here.
Weather Trivia: Snow in April? Of Course!
It might feel unfair, but Sudbury averages around 10 cm of snow in April — so tonight’s snowy cameo isn’t as strange as it seems. Just one of the joys of living where winter likes to linger.
