Crisp Morning Air, Sunny Afternoon Skies, and a Perfect Evening for Baseball
Early Spring Chill, but Warmth on Deck
Thunder Bay, ON – Wednesday, May 28, 2025: It’s a fresh spring morning in Thunder Bay, where Opening Night for the Border Cats baseball season promises not only hotdogs and home runs — but near-perfect weather, too. As of 6:00 AM, the temperature is a crisp 4.3°C at Thunder Bay Airport under mainly clear skies. The air is still, with a gentle west-northwest breeze at 5 km/h, and humidity is at 100%, thanks to a matching dew point. Visibility is solid at 16 km, and barometric pressure sits at 102.5 kPa and steady, pointing to a beautiful, stable weather day ahead.
Afternoon Warmth and Sunshine: Double Play Conditions
Today’s forecast calls for a mix of sun and cloud, with a high of 23°C inland, and slightly cooler conditions near Lake Superior, topping out around 17°C. That lake breeze may cool the outfield a little, but in the stands or the sun, it’ll feel just right. The UV index hits 7, so don’t forget sunscreen if you’re planning to cheer from the bleachers.
The ballpark atmosphere should be ideal by first pitch — warm, dry, and bathed in golden evening light.
Clear Skies for Opening Night Festivities
Tonight, skies remain clear, and temperatures will settle around 7°C — cool, but comfortable with a sweater or light jacket. Whether you’re staying through the ninth inning or just catching the fireworks, it’s going to be a beautiful spring night under the stars.
Thursday to the Weekend: A Weather Grand Slam
Thursday brings another day of sunshine, becoming partly cloudy by afternoon with a high of 27°C — downright summer-like. Thursday night stays clear with a low of 11°C.
Friday cools slightly with a high of 20°C, then Saturday bounces back with sunny skies and a high of 21°C. Both nights will be clear and comfortable, with lows of +4°C and +5°C respectively — excellent for evening strolls, backyard fires, or yes, more baseball.
What to Wear?
Mornings still call for a fleece or windbreaker, but afternoons will be T-shirt weather. If you’re heading to the Border Cats game, dress in layers and bring a cap or shades for the early innings and something warmer for the late-game chill.
Historic Temperatures for May 28
Thunder Bay’s record high for this date is 29.0°C, and the record low is -2.4°C. With a forecast high of 23°C inland and 17°C near the lake, we’re hitting the sweet spot between comfort and celebration.
