Blustery Start for the Nickel City, With Sunshine and a Gradual Warm-Up on the Horizon
Winter’s Last Gust? Windy and Cold in Sudbury, But a Turn Toward Milder Days Ahead
Greater Sudbury, ON – Tuesday, April 8, 2025 – The wind is howling and snow is drifting this morning in Sudbury, where winter is putting up a stubborn last stand. As of 6:00 AM EDT, the temperature at the Greater Sudbury Airport is sitting at a frigid -15.5°C, but it feels even worse thanks to strong northern winds at 23 km/h gusting up to 41 km/h. That breeze is pushing the wind chill to a biting -25°C—cold enough to put the brakes on any springtime enthusiasm. Humidity is at 69%, and the barometric pressure is rising at 101.4 kPa, signaling that the current flurry activity may soon ease up.
Early this morning there’s a 30% chance of lingering flurries, but skies will shift to a mix of sun and cloud through the day. Despite the sunshine, the high will only reach -4°C, and with continued gusty winds from the north at 20 km/h (up to 40 km/h), it will still feel closer to -10°C this afternoon. The UV index rises to a moderate 4, so there’s enough sun bouncing off those snowbanks to justify some SPF protection.
Tonight, things clear up, offering a peaceful evening sky—though the temperatures remain anything but warm. Northwest winds around 20 km/h will become light, and the low will plunge to -18°C. Expect wind chills near -10°C this evening, dropping to a frosty -20°C overnight.
Wednesday, April 9, brings sunnier vibes, with clear skies early and a few clouds moving in by midday. Winds will shift west at 20 km/h late in the morning, and the temperature will finally pop above freezing with a high of +1°C. Morning wind chills, however, will once again be downright painful at -22°C, so bundle up if you’re heading out early. The night will feature cloudy periods and a low of -5°C.
Thursday continues the warming trend with a mix of sun and cloud and a pleasant high of +5°C. Overnight temperatures dip only to -4°C. Friday rounds out the workweek with a similar mix of sun and cloud and a high of 6°C, with lows just below freezing at -3°C. The long, slow exhale from winter continues—finally.
What to Wear:
Layer up like you’re heading on an Arctic expedition this morning. Windproof outerwear, insulated boots, thermal gloves, and a hat that covers your ears are all non-negotiable. As the week progresses, you can trade in the heavy-duty parka for something a bit lighter, but you’ll still want to keep a warm coat within reach—especially for those sharp early mornings.
On This Day in Weather History:
Sudbury’s historical high for April 8 is a springy 15.4°C, while the record low reminds us how deep the cold can bite at -25.8°C. Today’s conditions put us somewhere between “classic Canadian chill” and “we’ll get through this.”
Weather Trivia Time!
Did you know? Sudbury has over 330 lakes within city limits—the most of any municipality in Canada. These lakes help moderate temperatures (eventually), but in the winter and early spring, they can also contribute to localized weather patterns like flurries and drifting snow. Just one more reason Sudbury weather always keeps you guessing!
