Crisp Skies and Crunchy Snow: A Wintry Weekend in the North
Weather Update for Sioux Lookout – Saturday, March 29, 2025
It’s a chilly start to the day in Sioux Lookout, where spring is running fashionably late. At 5:00 AM CDT, the temperature sits at -8.6°C under mostly cloudy skies. A light east-northeast breeze at 9 km/h is enough to bring the wind chill down to -13°C, while humidity is at 63%, and barometric pressure is at 102.2 kPa and rising. Visibility is excellent at 24 km, though we’ve got some light snow and a touch of freezing drizzle early on to keep things interesting.
Today’s Forecast: From Flurries to Sunshine
Early risers may notice a few flurries or freezing drizzle, but the skies will gradually clear to a mix of sun and cloud by midday. Winds will pick up slightly from the east at 20 km/h, then ease by late morning. Despite some sunshine, the high temperature will only reach zero, and wind chills will dip to -18°C this morning, before improving slightly to more manageable levels by afternoon. The UV index is 4, so yes—you can get a sunburn even at -5°C. Sunscreen isn’t just for beaches!
Tonight: Clear Skies and Deep Freeze
Bundle up if you’re heading out tonight—temperatures will fall to -12°C, and with winds up to 15 km/h, it’ll feel closer to -17°C. Clear skies will make for beautiful stargazing, but not without mittens and a thick parka.
Sunday: Sunny Start, Cloudy Finish
Sunday starts off bright and sunny but takes a turn toward increasing cloudiness by the afternoon. Winds shift from east to north at 20 km/h, and the high tops out at -2°C. Morning wind chills will flirt with -20°C, improving to around -7°C in the afternoon. That’s still thick mitten territory, folks.
Sunday night gets crystal clear again, but the temperature tumbles to -19°C. Monday follows with more sunshine and a high of -3°C, and Tuesday brings a slight warming trend with a high near zero and some clouds rolling in with a 30% chance of flurries overnight.
Historic Weather Fun Fact
Sioux Lookout is no stranger to cold March mornings. On this date in past years, the mercury has plunged well below -25°C, so today’s chilly -9°C is practically tropical by local standards.
What to Wear in Sioux Lookout Today
Don’t be fooled by the sun—this is still parka weather. Layer up with thermal underlayers, windproof jackets, and accessories that cover your ears and nose. Gloves, boots with grip, and sunglasses are all must-haves. If you’re venturing out tonight, add a neck warmer to the mix—your face will thank you.
