A Bright Sunday in the Nickel City Before Slippery Skies Return for the Workweek
Forecast for Sunday, April 13, 2025
Sudbury residents woke up this morning to mostly cloudy skies, but don’t let the grey fool you—there’s sunshine on the way! As of 7:00 AM EDT, the temperature at Greater Sudbury Airport sits at a cool 0.5°C with a south-southeast breeze at 11 km/h adding a light chill to the air. Humidity is relatively low at 59%, and visibility is excellent at 32 km. The barometric pressure is at 101.9 kPa and dropping slowly, signalling a change ahead.
Today’s forecast calls for a mix of sun and cloud with clearing skies expected by midday. We’re heading toward a mild high of 12°C—perfect for a spring stroll (or at least convincing yourself that winter is finally over). The UV index sits at a moderate 5, so if you’re soaking in some rays this afternoon, it wouldn’t hurt to slap on a bit of sunscreen.
Tonight: Cloud Cover Creeps Back with Risk of Ice
The clear skies won’t last long. Cloudiness increases tonight, and there’s a 30% chance of rain showers overnight—just enough to make things interesting. With the temperature holding steady at +1°C and the dew point low, there’s also a risk of freezing rain, especially in the early overnight hours. It’s one of those “don’t forget to salt the steps” kind of nights.
Monday, April 14: From Chilly Showers to Afternoon Rain
Monday’s forecast keeps things cool and cloudy. There’s a 30% chance of rain showers in the morning, with steadier showers expected to begin around noon. Freezing rain could make an early appearance again, so the morning commute may be slick. Winds will become southerly at 20 km/h by late morning, and the daytime high will only climb to around 7°C. The UV index will settle at a moderate 3, which is fitting for a mostly grey day.
Monday night stays cloudy, with a 70% chance of drizzle or snow—yes, the return of that white stuff again. The low will hover around 0°C, just enough to make things slushy and unpredictable.
Tuesday & Wednesday: Back to the Snow Zone
Tuesday, April 15, delivers periods of snow or rain and breezy conditions. The high will reach a chilly +1°C. By Tuesday night, snow takes over completely, and temperatures drop to -6°C—so grab your snowbrush again, just in case you were thinking of retiring it for the season.
Wednesday brings a mix of sun and cloud with a 40% chance of flurries. The high will reach a modest +3°C, and skies will clear by nightfall. Temperatures drop to -7°C overnight, reminding us that spring is still being a little shy this year.
What to Wear in Sudbury This Week
Think layers—and keep waterproof options handy. Today’s mild conditions call for light jackets, but tonight and into the workweek, you’ll need your warmer outerwear again. Gloves aren’t a bad idea for Tuesday and Wednesday mornings, and if you’re walking on untreated sidewalks during the freezing rain risk, winter boots might still be your best friends.
