Wardrobe Recommendations
Start the morning with a light jacket, hoodie, or sweater, especially if you are heading out early while temperatures are still near 6°C. By afternoon, lighter clothing should be comfortable as the temperature climbs into the mid-20s.
Because the UV index is high, bring sunglasses, sunscreen, and a hat for midday and afternoon plans. Drivers should be cautious early this morning where fog patches linger, especially near low-lying areas and waterways.
Weather Trivia
Sioux Lookout’s location near lakes, forest, and low-lying terrain makes it a good place for early-morning fog formation. When temperatures cool overnight and the air reaches saturation, fog can develop quickly, especially under calm winds like those observed this morning.
