Weather Trivia

Lake effect snow is a common phenomenon around the Great Lakes, where cold winter air moves over the warmer waters of the lakes, picking up moisture and depositing it as snow on the leeward shores. Geraldton/Greenstone’s proximity to Lake Superior makes it susceptible to this unique weather pattern, contributing to the area’s winter snowfall totals.
