From Zero to Sunshine – Northeastern Ontario Embraces the Spring Thaw
SUDBURY – WEATHER – Don’t be fooled by the thermometer—it may only be 0.4°C this morning at Greater Sudbury Airport, but better days are literally hours away. It’s a chilly start that feels more like April’s stubborn leftovers than a proper May morning. The skies are grey, the wind is a gentle 9 km/h from the north-northeast, and the air is thick with moisture, registering a humidity of 92%. The barometric pressure is sitting at 101.7 kPa and on the rise, which bodes well for a clearing trend just around the corner. Visibility is excellent at 32 kilometres, so at least you can see spring even if you can’t quite feel it yet.
Afternoon Sunshine and a Weekend Warm-Up
Sudbury can look forward to a steady and satisfying improvement as the day wears on. The clouds will start packing their bags this afternoon, making way for sunshine and a high of 12°C. The UV index will climb to 6, which is considered high—so if you’re heading out for a stroll or prepping the garden, slap on a bit of sunscreen even if you still need a jacket.
Tonight brings clear skies and slightly brisk conditions, with the temperature dipping to a low of 2°C. Winds will shift and pick up from the north at 20 km/h overnight, adding a crisp edge to the otherwise peaceful evening.
Sunday is shaping up to be picture-perfect, with clear skies and full sun on tap. Northern winds at 20 km/h in the early morning will become light by midday, and temperatures will climb to a mild and lovely 15°C. The UV index will be 7, also in the high range—sunglasses and SPF are your spring best friends. Sunday night stays clear with a low of 4°C, a great setup for overnight star-gazing or early season camping.
Monday brings back the clouds, with a 30 percent chance of showers and a high of 15°C. That slight chance of rain continues Monday night, with cloudy skies and a low of 10°C to round out the start of the work week.
Wardrobe Wisdom and a Dash of Weather Trivia
This morning, think layers with a warm jacket and maybe a toque if you’re heading out early. By the afternoon, you’ll likely be peeling some of that off under sunny skies. Sunday’s sunshine will call for lighter clothing, but don’t ditch the windbreaker just yet.
Today in Sudbury weather history: The warmest May 3rd on record hit 27.8°C in 2001, while the chilliest came in 1986 when the city shivered down to -4.2°C. So while it may feel like a blast from April’s past this morning, we’re well within Sudbury’s spring weather norms.
