Tuesday Brings Damp Mornings, Fog Patches, and a Peek of Sunshine in Thunder Bay
Thunder Bay – Weather – The weather advisory that called for drenching rains kind of fizzled into drizzles of rain for much of the city.
This morning, post rainfall advisory, Thunder Bay wakes up to a damp and misty Tuesday morning, but don’t let the drizzle fool you — the day is slowly set to brighten. As of 7:49 AM EDT, it’s a cool 12.4°C with light drizzle falling over the city, and the air is so saturated that the humidity sits at 100%.
Visibility is reduced to 3 km, making it a foggy, misty start at Thunder Bay Airport. The wind is a gentle 4 km/h from the west-southwest, and the barometric pressure is 101.3 kPa and falling, suggesting a gradual weather shift is in motion.
Today’s Forecast – From Gloom to Boom (Well, at Least Some Sun)
If you’ve woken up thinking you’re in a coastal fishing village, you’re not alone — the drizzle, fog, and still air are painting a moody picture. But there’s good news: while there’s a 40% chance of lingering showers this morning, things will start to dry out and brighten as we move through the day.
Fog patches will dissipate by late morning, giving way to mainly cloudy skies with temperatures climbing to a comfortable high of 20°C.
Tonight, we’ll see partly cloudy skies, but fog patches will redevelop, so drivers — have those headlights on and your coffee brewed if you’re up early Wednesday. The overnight low will dip to 10°C.

Weather Trivia: Fog Capital of the West?
Thunder Bay’s geography — nestled between Lake Superior and the Canadian Shield — makes it a prime fog hotspot during transitional seasons. Cool lake breezes mixing with warm autumn air often lead to those thick morning mists. It’s beautiful… if you don’t have to catch a flight or drive Highway 11 before sunrise!
