Lake Superior weather is cool throughout the year. Temperatures rarely exceed 80 degrees Fahrenheit when sunny. Dense fog is common in the spring, and thunderstorms and rain occur throughout the season. Weather and rough seas may delay departures to and from the island.

Bring plenty of warm clothing, even in August. A jacket is a must for the ferry trip to the island, and for boating around the island.
