THUNDER BAY – Spring is still taking its time in Thunder Bay. The weekend was supposed to be far warmer with earlier forecasts calling for a +12c on Sunday. However it looks like someone crazy glued Old Man Winter into his lounge chair.
While Environment Canada shows no alerts in effect Saturday morning, the city remains locked in a chilly pattern with a late-morning temperature of -8.4°C, a wind chill of -14, and periods of light snow expected to begin near noon.

Wardrobe Recommendations
Saturday is still a winter-clothing day. A warm coat, gloves, and a hat are a good idea, especially through the morning with wind chills in the minus teens. Waterproof footwear also makes sense with light snow expected to move in by midday and more snow in the forecast for Monday and Tuesday.
Weather Trivia
Thunder Bay’s listed normals for this point in late March are 5°C for the daytime high and -7°C for the overnight low. Saturday’s forecast high of 0°C sits noticeably below seasonal, which helps explain why spring still feels stuck in low gear. Environment Canada also lists sunrise at 7:44 AM EDT and sunset at 8:21 PM EDT, so the days are getting longer even if the warmth is not quite here yet.
Summary
Thunder Bay weather for March 28, 2026: no alerts in effect, but spring remains slow to arrive as the city stays cold at -8°C this morning with light snow expected by noon.
