Weather Trivia for Thunder Bay
Thunder Bay’s location along the northern shore of Lake Superior plays a major role in its weather patterns. During fall, the lake has a moderating effect, often keeping daytime temperatures milder, but the cold water can lead to chilly mornings and gusty winds as the air masses shift. Historically, the city sees its first frost by mid-October, with snow typically starting in November. However, this period of sunny days and moderate temperatures is a reminder of Thunder Bay’s unpredictable fall weather, which can quickly shift from pleasant to wintry.
October in Thunder Bay can also bring significant temperature swings, with the largest recorded drop between day and night reaching over 20°C. The region’s history of early snowfalls, especially in late October, means that while temperatures are currently mild, the first snow is never far off.
