From Wind Chill to Sunshine – Thunder Bay Warms Up (Slowly but Surely)
THUNDER BAY – WEATHER – If you’re stepping out this morning and wondering why it feels like winter’s ghost is still lurking—don’t worry, it’s on its way out. As of 6:29 AM at Thunder Bay Airport, the temperature is a chilly 2.4°C, with a dew point of 1.2°C and a humidity of 92% making the air feel a bit heavier than it looks. Winds are light from the south at 5 km/h, and with that breeze, there’s still a lingering wind chill of -6°C just to keep you humble.
Barometric pressure is at 101.7 kPa and falling, signaling some change in the skies ahead. Visibility is crystal clear at 32 km—so you’ll definitely see the sunshine when it shows up.

Spring Weather Starts to Take Hold, One Degree at a Time
Today’s skies will begin mostly sunny but cloud cover will increase through the morning. Don’t panic though—it’s not the gloomy, rainy kind. Winds will pick up from the southwest, reaching 20 km/h and gusting to 40 by late morning. This will help bump the mercury up to a solid high of 16°C by afternoon. With a moderate UV index of 5, you’ll want to throw on a bit of sunscreen if you’re out soaking up the rays.
Tonight, expect skies to clear near midnight after a partly cloudy evening. Temperatures will drop to a cool low of +1°C, so a jacket by the campfire is still a must.
Sunday brings another round of sunshine, although a bit cooler than today with a high of 11°C. The UV index rises to 7 (high), so despite the cooler air, the sun means business. Sunday night clears out with a low of -1°C—yes, a frost warning in disguise, so cover those early-bloomers!
Monday continues the sunny streak with a slightly warmer high of 14°C. Clouds creep in by night, with a low of +2°C and no precipitation in sight.
Tuesday cranks things up a notch with a mix of sun and cloud and a surprisingly warm high of 21°C. Overnight, it stays cloudy with a low of 2°C—a great sign that spring has officially unpacked its bags.
Wardrobe Tips & Thunder Bay Weather Throwback
You’ll want gloves this morning, but by lunchtime, you’ll be safe in a light jacket or even a hoodie. Sunday’s chillier vibe will keep long sleeves in play, but Monday and especially Tuesday? Break out the t-shirts and plan that lunch break walk.
Fun fact: Thunder Bay’s warmest May 3rd on record hit 26.7°C in 1998, while the coldest was a frosty -5.6°C in 1974. Today’s 16°C won’t break records, but it certainly breaks the streak of soggy spring weather we’ve been trudging through.
