Wardrobe Recommendations
This is still “cover every inch” weather, especially in the morning:
-
Thermal base layer + warm mid-layer + windproof parka
-
Mitts, insulated boots, and thick socks (avoid tight boots that cut circulation)
-
Face protection (neck gaiter or balaclava) is key with wind chills near -30
-
If commuting or travelling: keep spare gloves/hat, a phone charger, and a warm blanket in the vehicle.
Weather Trivia
Even when the thermometer improves, wind is the game-changer. A 20–40 km/h breeze strips away the thin layer of warmth around your skin, which is why -22°C can feel like -32—and why covering exposed skin matters as much as the coat you wear.
Summary
Thunder Bay weather forecast for Tuesday, January 27, 2026: mainly clear and very cold near -22°C with wind chill -32. Mainly sunny today, flurries possible overnight, and continued below-normal temperatures through Thursday.
