Today’s Weather Overview
Current Conditions
At 6:00 AM EDT, Thunder Bay Airport was reporting fog and a temperature of 12.1°C. The dew point was also 12.1°C, with humidity at 100 percent, meaning the air is fully saturated. Winds were from the east-northeast at 15 km/h, visibility was sharply reduced to 0.4 km, and the barometric pressure was 100.8 kPa and falling.
Today will remain cloudy, with fog patches dissipating this morning. The high will only reach 15°C, making it a cooler day for mid-June. The UV index is 6, or high, so sun protection is still recommended if the clouds thin during the day.
Tonight brings showers, ending before morning, followed by cloudy conditions. There is also a risk of a thunderstorm, along with more fog patches. The overnight low will be 11°C.

Wardrobe Recommendations
For Wednesday morning, visibility is the bigger concern than temperature. Drivers should use low-beam headlights, slow down, and leave extra space on the road. For walking or commuting, a light jacket and water-resistant footwear are good choices, especially with damp fog and showers expected later.
Thursday will feel much warmer, so lighter clothing will be comfortable by afternoon. However, with a very high UV index, sunglasses, sunscreen, and a hat are strongly recommended.
Weather Trivia
Thunder Bay gets a long June day today, with Environment Canada listing sunrise at 5:56 AM EDT and sunset at 9:57 PM EDT. That gives the city just over 16 hours of daylight, even if the morning begins under thick Lake Superior fog.
