From a Gloomy Start to a Glorious Spring Weekend in Northwestern Ontario
SIOUX LOOKOUT – PICKLE LAKE – WEATHER – It may be a modest 2.5°C this morning at Sioux Lookout Airport, but don’t let the clouds and that damp, heavy air fool you—spring has big plans for the weekend. Conditions are mostly cloudy with 93% humidity, a dew point of 1.5°C, and a gentle breeze from the south at 9 km/h. The barometric pressure is at 101.4 kPa and falling, hinting at a bit of unstable air, which aligns with the early-morning sprinkle potential. Visibility is a solid 24 km, so you’ll see that sunshine well before you feel it.
Showers Fade, Skies Clear, and Temperatures Soar
This morning kicks off with a 40 percent chance of showers and a reminder of winter’s bite—thanks to a wind chill that makes it feel like -6°C early on. But this chill won’t stick around. By late morning, winds will shift south at 20 km/h, gusting to 50, before turning west at 20 km/h with gusts up to 40 by this afternoon. The clouds will clear as the day progresses, and temperatures will climb rapidly, reaching a spring-lifting high of 17°C. The UV index will rise to a high 6, so be sure to shield that freshly-thawed face.
Tonight brings clear skies and a comfortable low of +3°C. Winds from the northwest at 20 km/h will gust up to 40 before easing off, leaving the region with a calm and refreshing night.
Sunday is shaping up to be a stunner across both Sioux Lookout and Pickle Lake. Expect full sun and a daytime high of 21°C. The UV index jumps to a high 7—so yes, sunscreen is now officially part of your weekend wardrobe. Sunday night remains clear with a low of 7°C.
Monday carries the sunny streak forward with another beautiful day and a high of 22°C. That’s true t-shirt weather for Northwestern Ontario. Monday night will stay clear with a low of 8°C—great for evening walks, fire pits, or just soaking up the peaceful night air.
Dress Code and a Dose of Weather Trivia
Start the day bundled up with a windbreaker and layers—especially if you’re stepping out before that wind chill disappears. But be ready to strip down to lighter gear by lunch, and bring those shades! Sunday and Monday will feel like nature’s reward for getting through that long, stubborn winter.
Today’s historical weather fun fact: On May 3rd, Sioux Lookout once hit a record high of 26.3°C back in 2001, and a record low of -5.6°C in 1967. So while 17°C might not be a record-breaker, it’s definitely a crowd-pleaser.
