A Chilly Start with a Warm (and Wet) Twist to Come
Greater Sudbury, ON – It’s a crisp but cheerful Easter Sunday in the Nickel City. As of 7:00 AM EDT, the Greater Sudbury Airport is reporting a temperature of -2.0°C under mainly sunny skies. The morning chill is accentuated by a light north wind at 6 km/h, creating a wind chill near -4°C. Humidity is at a moderate 71%, visibility is an impressive 32 km, and the barometric pressure is sitting high at 103.1 kPa and rising—a calm before a little springtime storm activity arrives.
Today’s Forecast: Soak Up the Sunshine While You Can
Today is a beauty, with abundant sunshine expected and just a gentle breeze up to 15 km/h. The high will climb to 9°C—mild and manageable for this time of year. This is your best chance to enjoy the outdoors, because changes are on the way soon. The UV index is a 6, which is considered high, so don’t be fooled by the cool air—sunscreen is still a must if you’re outdoors hunting for eggs or working in the garden.
Tonight: Clear Early, Then the Clouds—and Rain—Roll In
Skies will stay clear through the evening and into the early overnight hours, but cloud cover will increase closer to morning, bringing a 40% chance of rain before sunrise. Winds will shift to the southeast and increase to 20 km/h overnight, and temperatures will hold just around the freezing mark at 0°C. It’ll feel milder than it has been, but an umbrella on standby won’t hurt.
Monday: April Showers… and Wind Gusts
Easter Monday ushers in a solid dose of classic spring rain, with periods of rain expected throughout the day and total amounts ranging from 10 to 15 mm. Winds will ramp up from the southeast at 30 km/h, gusting to 50—enough to flip a recycling bin or send your umbrella inside-out if you’re not careful. The high will only reach 6°C, and the UV index drops to 2 (low), not that you’ll see much sun anyway.
The rain continues into Monday night, with temperatures rising slightly to a low of +3°C. Expect a damp, gusty, and grey evening across the region.
Midweek Outlook: Gradual Improvements
Tuesday remains on the cloudy side with a high of 8°C, while Tuesday night sees clearing skies and a low of +1°C.
Wednesday brings a mix of sun and cloud and a high of 10°C—progress! And by Thursday, it really starts to feel like spring, with a high of 14°C under partly sunny skies. Thursday night will be cloudy, with a mild low of 4°C.
Historic Weather Snapshot
On this date, Sudbury’s warmest April 20 on record reached a balmy 22.4°C in 1983. The coldest was a brisk -11.7°C in 1972. So today’s high of 9°C may not be record-breaking, but it’s well within the bounds of Sudbury’s moody spring history.
Wardrobe Wisdom
Morning: A winter coat, gloves, and scarf won’t go unappreciated early on.
Afternoon: Light layers and a windbreaker will keep you comfortable.
Evening: Toss on a waterproof shell—just in case those overnight showers arrive early.
Weather Trivia: Sudbury’s Sudden Showers
Did you know? Sudbury’s topography and proximity to several lakes make it prone to sudden, localized spring showers—even when radar looks relatively quiet. It’s not uncommon for one neighbourhood to be soaked while the next street over stays dry. When locals say, “Wait five minutes,” they’re not exaggerating!
