Winter Weather Advisory in Effect – Snowfall, Blustery Breezes, and Chilly Wind Chills
Current Conditions as of 5:43 AM – Monday, March 24, 2025
Greater Sudbury is waking up to a classic Northern Ontario spring curveball — a winter weather travel advisory remains in effect, and it’s snowing steadily this morning. At the Greater Sudbury Airport, the temperature is sitting at -6.7°C, with light snow falling and visibility reduced to just 1.6 km. The wind is coming in from the east-northeast at 21 km/h, producing a wind chill that makes it feel more like -14°C. Humidity is at 89%, and the barometric pressure reads 100.1 kPa — falling steadily, hinting that we’re not quite out of the woods yet.
Snowfall today is expected to total between 10 and 15 cm, with areas closer to Georgian Bay likely seeing the higher end of that range. Winds from the east at 20 km/h (gusting to 40) will lighten up mid-morning, only to shift north and gust back up to 40 km/h again later this afternoon. The high will nudge just above freezing at +1°C, but the chill in the air — especially this morning — will have you feeling like it’s still the dead of winter. UV index? A barely-there 1.
Tonight’s Forecast: Snow Sticks Around, Winds Stay Brisk
Don’t put the shovel away just yet. Periods of snow will continue tonight as northwesterly winds persist at 20 km/h, with gusts up to 40 km/h. The low drops to a cold -6°C, and wind chills will hover around -12 overnight. Not quite the spring slumber we were hoping for.
Tuesday and Beyond: A Light Flurry of Hope
Tuesday brings more snow — though thankfully on the lighter side. Periods of light snow are expected, with gentle winds up to 15 km/h. The high reaches only -2°C, with a brisk wind chill of -12 in the morning and -4 by the afternoon. The evening will bring cloudy periods and a 30% chance of lingering flurries, with a low of -11°C.
Wednesday teases improvement with a mix of sun and cloud and a daytime high of +1°C, before clearing out under starlit skies and a low of -5°C. By Thursday, we see a 60% chance of rain showers or flurries — a true spring identity crisis — with a daytime high of +3°C. The night cools back down to -11°C.
Historic March 24 Weather in Sudbury
Sudbury’s weather history doesn’t shy away from extremes. The warmest March 24 on record saw thermometers soar to a surprising 17.0°C in 1945, while the coldest day was a biting -27.8°C back in 1974. So, while today’s -6.7°C feels frosty, we’ve certainly seen worse—and better.
What to Wear: Think Winter Warrior
Today’s outfit should include your warmest winter coat, snow boots, gloves, and a toque that won’t fly off in gusty winds. Visibility is limited and snow is stacking up fast, so keep those cozy layers close and your windshield scraper closer.
Sudbury Weather Trivia
Here’s a frosty fact: Sudbury averages over 250 cm of snowfall each year, making it one of the snowiest urban centres in Ontario. If you’ve ever wondered why your arms are sore from shovelling, now you know — you live in the heavyweight division of Canadian snow zones.
