Winds will increase, becoming southwest at 20 km/h with gusts up to 50, and then shifting northwest by afternoon with continued gusts. The high will reach 20°C, and the UV index is 6 (high).

Weather Trivia

Did you know?
Wildfire smoke can travel thousands of kilometres and still impact air quality and health — even in areas far removed from active fires. During large fire events in 2021, smoke from Western Canada reached as far as Europe. While today’s smoke in Sioux Lookout is more localized, its health effects are just as real.
