Rainy Morning Gives Way to Drier Skies and Weekend Recovery
Light Rain Starts the Day, but Dry Patches Ahead
Greater Sudbury begins Thursday with a gentle soaking. As of 7:00 AM, it’s a mild 14.3°C at Sudbury Airport with light rain, 90% humidity, and a damp dew point of 12.6°C — basically, it’s a hair-frizzing kind of morning. Winds are out of the northeast at 9 km/h, and visibility is decent at 19 km, though you may want to use your windshield wipers on the drive in.
The barometric pressure is 102.2 kPa and rising, suggesting that today’s soggy start may give way to some atmospheric balance. Rainfall is expected to continue through the morning with 5 to 10 mm likely before easing around noon. The rest of the afternoon brings a mix of sun and cloud, along with a 30% chance of lingering showers, so keep the umbrella close by just in case. Temperatures will reach a high of 20°C, and the UV index will spike to 10, very high — meaning the moment the sun does show up, it’ll be intense.
Tonight & Friday: Rain Rebounds Hard
Thursday evening stays partly cloudy, with a continued 30% chance of showers early in the night. But don’t get too comfy — periods of rain are expected to begin after midnight, delivering another 5 to 10 mm of moisture. The overnight low will dip to a cool 11°C, making it ideal for cozying up indoors with a warm drink and a good forecast (like this one!).
Friday is expected to be a washout, with steady rain and amounts between 20 and 30 mm throughout the day. Winds will pick up from the east at 20 km/h, gusting to 40 in the morning before easing in the afternoon. The daytime high will only reach 17°C, and with a UV index of 2, you won’t need the sunglasses, but you will need the raincoat.
Friday night stays cloudy with a 30% chance of showers and a mild low of 14°C.
Saturday: Drying Out and Brightening Up
By Saturday, the clouds hang around, but the rain should be gone. Expect cloudy skies and a high of 20°C — a much more manageable day, especially for weekend plans. The skies clear overnight, dipping to a low of 13°C, making for a quiet, calm night under the stars.
What to Wear: Waterproof Now, Lighter Later
Today is a classic “layers and umbrella” kind of day — waterproof outerwear and shoes are essential this morning, but by afternoon, you may find yourself peeling back to a light jacket or hoodie as skies brighten. Sunglasses and sunscreen will come in handy too, especially with that surprise UV surge. Friday? Full-on rain gear from head to toe. Saturday’s look: comfortable, casual, and cloud-compatible.
Historic Weather & Local Lore
On this date, Sudbury’s record high was 32.2°C, set back in 1975, and the record low dipped to 5.6°C in 1962. Today’s high of 20°C lands safely in between — no heat waves, no chills, just a soggy start and mild afternoon.
Did you know? Sudbury sits on a 1.8 billion-year-old meteorite impact crater, and its weather can feel just as dramatic. With more than 1100 mm of precipitation annually, this city knows its rain — but also knows how to bounce back into sunshine quickly.
