Gorgeous Tuesday With Classic Summer Vibes
Good morning, Thunder Bay! You’re waking up to one of the best summer mornings on the weather menu — partly cloudy skies, a comfortable 13.9°C, and the scent of sunscreen already in the air. Humidity sits at 82%, giving the breeze a gentle, slightly damp feel, while the dew point at 10.8°C confirms that this is the perfect weather for that early coffee on the deck.
The barometric pressure is at a calm and promising 102.2 kPa and rising, signaling continued stable weather, at least for the day. Winds from the west are taking it easy this morning at just 8 km/h, and visibility is an excellent 32 km — perfect if you’re planning a lakeside escape or heading up to the Sleeping Giant.
By this afternoon, the skies will be bright and sunny with a high of 24°C, feeling like 25°C with the humidex — a warm, manageable kind of heat. But with a UV index of 9, categorized as very high, don’t skimp on the sunscreen and shades. That northern sun packs a punch this time of year!
Tonight and Midweek: A Shift Toward the Cloudy Side
Tonight will be clear and calm, with the temperature dipping to a fresh and comfy 9°C — perfect sleeping weather with the windows open and just a hint of the lake breeze.
Wednesday brings another sunny start, with clouds rolling in by early afternoon. Temperatures rise a little more to a high of 25°C, humidex 26, and again a UV index of 9, so your SPF is still working overtime. Wednesday night turns cloudier, with a 30% chance of showers and a mild low of 13°C.
Thursday and Friday continue the trend toward cloudier conditions. Thursday’s high will reach 22°C, and Friday will be slightly cooler at 21°C, with both nights hovering around 13°C and 11°C respectively. No heavy rainfall is expected just yet, but the clouds are hanging around like that one guest who lingers after dinner — not unwelcome, just a little clingy.
What to Wear: Dress for Sun — but Don’t Forget a Light Layer
Today’s all about breathable fabrics, short sleeves, and sun protection. Bring a hat, sunglasses, and lots of water if you’re planning outdoor activities. Evening attire can be dialed back to a light sweater or windbreaker — just enough to enjoy the patio without a chill.
Thunder Bay Weather Trivia & Historic Notes
On this day, Thunder Bay has seen extremes on both ends of the thermometer. The record high for June 24th was 32.8°C, set in 1988, while the chilliest was 4.4°C, going all the way back to 1967. Today’s high of 24°C lands us right in the “just right” zone — warm enough for summer activities without breaking a sweat.
Did you know? Thanks to its position on the northwestern shores of Lake Superior, Thunder Bay experiences the moderating effect of the lake — keeping summers pleasantly warm and rarely oppressively hot. That also means when storms do roll in, they can bring dramatic skies and stunning sunsets.
