SUDBURY – May 2, 2025 – Sudbury’s Friday forecast is kicking off on the soggy side, with light drizzle and 100% humidity doing their best to make the morning feel like someone forgot to turn off the sky. As of 6:25 AM at Greater Sudbury Airport, it’s a damp 4.2°C, and with the dew point sitting at an identical 4.2°C, the air is fully saturated—Mother Nature’s version of a damp handshake. Winds are coming in gently from the north at 9 km/h, and visibility is reduced to just 2 km under the misty, drizzle-filled sky. The barometric pressure is at 100.1 kPa and falling, suggesting the grey skies aren’t in any hurry to leave.
Expect rain, often mixed with drizzle, to linger throughout the day as the temperature climbs to a high of just 8°C. Winds will shift this afternoon to come from the northwest at 20 km/h, adding a brisk edge to the damp conditions. The UV index sits at a moderate 3—not exactly sunbathing weather, unless you’re a mushroom.
For a bit of historical perspective, Sudbury has experienced its share of weather extremes on May 2. The record high was a summery 25.2°C set in 2001, while the record low dropped to a chilly -6.1°C way back in 1975. Today lands firmly in the “meh” category—a far cry from sizzling, but thankfully not freezing either.
Tonight brings more cloud cover and a 60 percent chance of showers or drizzle early in the evening. Winds from the north at 20 km/h will lighten late this evening, with temperatures dipping to a low of 0°C. It’ll be a chilly night, so if you’re heading out, layer up—and maybe reconsider that patio dinner plan.
Saturday starts cloudy but shows promise. The clouds will begin to clear later in the afternoon as temperatures rise to a more pleasant 13°C. The UV index holds steady at 3. A noticeable shift in mood arrives Saturday night, which will be clear and calm with a low of 5°C—perfect sleeping weather if you’ve had enough of the drizzle.
Sunday is looking like a genuine spring gem. Expect full-on sunshine and a high of 19°C, ideal for anything from backyard gardening to a lakeside picnic. Sunday night remains clear with a low of 4°C—no complaints there.
By Monday, a few more clouds creep in, bringing a 30 percent chance of showers. Still, the day should see a high of 16°C with mixed skies. Clouds increase overnight, with a mild low of 9°C.
Today’s wardrobe should lean heavily into waterproof gear. Think rain jacket with a hood, sturdy shoes that don’t mind puddles, and maybe an extra layer for when those northwest winds pick up later. An umbrella might help—though in Sudbury, the sideways drizzle sometimes has other plans.
Here’s your Sudbury weather trivia for the day: Did you know Sudbury’s unique landscape of lakes and rock actually amplifies local weather effects? All those exposed granite surfaces heat and cool faster than forested land, which can enhance fog, wind gusts, and yes—those persistent drizzle days. It’s local geology working double duty as a weather machine!
