SUDBURY, ON – WEATHER REPORT – Sudbury’s Thursday is getting off to a slick and slippery start with light freezing drizzle and temperatures hovering just below zero. Observations from Greater Sudbury Airport at 6:00 AM show the temperature at -0.5°C, with a wind chill of -3 thanks to a gentle southeast breeze at 8 km/h. Visibility is limited at just 1.6 km due to the drizzle, and the air is nearly saturated with a humidity reading of 99%.
The barometric pressure stands at 100.0 kPa and is on the decline, signaling the approach of more unsettled weather as the day unfolds. If you’ve got morning errands or a commute, take it slow—surfaces may be slick with that freezing drizzle still lingering.
Afternoon Winds Whip Up as Temperatures Dip
Today’s forecast keeps things grey, with a 40 percent chance of drizzle or light rain and a continuing risk of freezing drizzle early on. As the morning progresses, winds will shift to the southwest and pick up dramatically—expect steady winds of 40 km/h, gusting up to a blustery 70. Hang onto your hats (and maybe small pets), because this wind is no joke!
And just to make things a little more curious, temperatures are expected to fall as the day goes on, landing at the freezing mark by the afternoon. So while it’s not a deep freeze, that combo of gusty wind and light moisture might feel more like late February than early April. UV index will rise to 3, a moderate level—so there might be a few sneaky rays poking through later in the day.
Cloudy and Cool Tonight with a Chance of Flurries
Tonight, expect mostly cloudy skies with a 30 percent chance of rain showers or flurries in the evening. Winds from the west will gust to 40 km/h before calming down late in the evening. The overnight low will dip to -6°C, with a wind chill of -8, so you’ll want to keep that warm jacket close by.
Friday begins cloudy but will clear up early in the afternoon, bringing a bit of sun back to town and a high of +8°C. Morning wind chill will feel like -8, so layers are still your best friend. Friday night stays mild with a low around zero under partly cloudy skies.
Saturday returns to grey skies and a 30 percent chance of showers, with a daytime high of +3°C. Sunday keeps that unsettled spring theme going, offering a mix of sun and cloud with a 30 percent chance of flurries or rain showers and a high of +3°C. Sunday night sees a return to colder air with flurries possible and a low of -9°C.
Dress Code: Rain-Ready, Windproof Layers
It’s a perfect day for weather versatility. Start with a warm base layer, add a windproof outer shell, and definitely don’t forget the umbrella—though you might need to wrestle with it in those gusts. Footwear with good grip is a smart call, especially early this morning when surfaces might be icy.
Historic Weather Note for Sudbury
April 3rd has been a mixed bag for Sudbury in the past. The record high for today is a pleasant 18.3°C, set in 1981, but the record low? A teeth-chattering -23.3°C, way back in 1975. Today’s -0.5°C feels like a cautious compromise—right in that awkward middle ground between parka and patio.
