Today’s Forecast for Greater Sudbury

Good morning Sudbury! At 7:00 AM EDT, it’s a mild 11.3°C at the Greater Sudbury Airport under mostly cloudy skies. The air feels fresh with a dew point of 6.0°C and a comfortable humidity level at 70%. Winds are already picking up out of the south-southwest at 24 km/h, gusting to 33 km/h, and visibility is excellent at 32 kilometres — for now! Pressure sits at 100.3 kPa and is falling, a clear sign that a weather system is moving in.

Today’s forecast calls for showers, with the added drama of a possible thunderstorm, just to keep things lively. Winds will intensify, shifting southwest at 30 km/h with gusts up to 60 km/h, and by this afternoon they’ll swing around to the north at the same gusty speeds. Despite the stormy setup, temperatures will soar to a delightful 17°C — perfect if you don’t mind dodging a few raindrops. The UV index will hit 5, moderate, so even brief sunny breaks deserve a bit of sunscreen.

Tonight and Tomorrow: A Cold Snap After the Storm

Tonight, the action slows but doesn’t fully calm. Skies will stay cloudy with a 40% chance of rain showers or flurries this evening (yes, you read that right — flurries). Winds from the north at 30 km/h, gusting to 60 km/h, will ease after midnight, but temperatures will take a nosedive to a frosty -5°C. The overnight wind chill will bite down to around -11°C, so don’t be fooled by today’s balmy tease — winter’s still lurking in the wings.

Wednesday, April 30th, starts cloudy but clears by late morning. Winds will stay light at up to 15 km/h. After a biting morning wind chill of -9°C, the day will recover nicely to a high of 8°C, with the UV index climbing to a strong 7 — high enough to call for sunscreen again.

Wednesday night will be crisp but clear with a low of +1°C.

Heading into May: Showers Return

Thursday, May 1st, will see clouds creeping back in with a high of 12°C. Thursday night brings a 40% chance of showers and a mild low around 6°C. Friday, May 2nd, looks a little wetter, with a 60% chance of showers during the day and a high of 9°C. Friday night could end on a dramatic note with a 60% chance of rain showers or even flurries and a chilly low of -1°C.

Historic Highs and Lows for April 29

For those keeping score, Sudbury’s record high for April 29th is a sizzling 26.5°C set back in 1952 — a true early summer treat! On the colder end, the mercury once plunged to a brisk -8.0°C back in 1959. Today’s high of 17°C is sitting comfortably in between — a little drama, but not too wild!

What to Wear?

Start the day in layers you can peel off! A rain jacket is a must, and waterproof shoes will save your feet from soggy surprises. An umbrella could help, but with those gusty winds, it might be more useful as a temporary parachute. Tonight, it’s full-on winter gear again with a heavy jacket, hat, and gloves for anyone heading out.

Sudbury Weather Trivia
