A Damp and Chilly Start to Saturday in Sudbury
Greater Sudbury is easing into Saturday under a grey, moisture-laden sky, sitting at 6°C as of 7:00 AM. Conditions are cloudy, and there’s a 60 percent chance of morning showers with lingering fog patches expected to clear as the day goes on. The air is saturated with 100% humidity, and the dew point is holding equal to the temperature at 5.5°C—meaning it feels exactly as damp as it is. Winds are currently coming from the north at 9 km/h, but by this afternoon, they’ll pivot northwest and pick up to 20 km/h.
The barometric pressure is sitting at 100.4 kPa and trending downward, signaling that today’s overcast skies and showers are part of a broader unsettled pattern. Visibility remains decent at 16 km, but with everything feeling cool and clammy, it’s not exactly a patio brunch kind of morning.
Despite the gloomy setup, don’t expect a major warm-up. The daytime high is forecast to reach just 6°C, and with a UV index of 2 (low), sun protection can stay on the shelf. A light, waterproof jacket is a solid choice, and you’ll want to keep the layers handy, especially if you’re heading out early or later this evening.
Frosty Surprise on the Way Tonight
Tonight, Sudbury shifts from damp to downright cold. Cloud cover will begin to break near midnight, making way for some partial clearing. But with that clearing comes a steep drop in temperature. Expect an overnight low of -6°C, paired with northwest winds gusting to 40 km/h before easing to light by the early morning. With those brisk winds, it’ll feel closer to -9°C—so if you’ve already retired the winter gear for the season, now’s the time to reconsider.
Sunday Brings Sunshine But Keeps Its Cool
After a frosty start, Sunday will be a welcome break in the clouds. Sunny skies and calmer conditions will dominate the day. Winds will stay light, peaking around 15 km/h. But don’t be fooled by the sunshine: a morning wind chill of -8°C will remind you that we’re not in full spring mode just yet. By afternoon, temperatures will climb to a more comfortable high of 10°C. With a UV index rising to 6 (high), sunscreen and sunglasses make a comeback.
Sunday night sees increasing cloudiness again and a low right around the freezing mark at 0°C. At least we’re done with subzero—briefly.
A Soggy Start to the Week, But Some Hope Ahead
Looking ahead, Monday brings a return to wet weather with periods of rain during the day and evening. Temperatures will remain mild, with a daytime high of 6°C and an overnight low of 1°C.
Tuesday offers a brief pause from the rain, though the clouds won’t be going anywhere. The high will be just 5°C, and that night, skies finally start to clear, leaving a low of +1°C. It’s a slow climb, but spring does seem to be making baby steps in Northern Ontario.
What to Wear
If you’re heading out today, waterproof layers and a hat are a must. This evening and into early Sunday, you’ll want full winter gear again, including a hat and gloves to brave that -9°C wind chill. Sunday afternoon brings a slight relief, but don’t pack away the coat just yet. Come Monday, the rain gear will get another workout—boots and a sturdy umbrella are highly recommended.
Sudbury’s Weather History: From Balmy to Bitter
April 19 in Sudbury has had a bit of a split personality over the years. The warmest on record was a pleasant 23.9°C in 1960, offering a perfect glimpse of early summer. But the coldest this date has ever delivered was a teeth-chattering -12.2°C in 1992—a reminder that the North always keeps a few surprises in its back pocket. Today’s chilly, damp forecast sits comfortably in the middle, though the overnight dip is certainly leaning toward Sudbury’s frostier heritage.
