Climate in Isle Royale National Park
At a latitude of 48�North, and with the moderating influence of cold Lake Superior, Isle Royale rarely gets hot by human standards. During the summer months you'll reach shorts-and-t-shirt weather in the afternoon, especially hiking up on the ridges, but you'll also experience some rather chilly nights, sometimes even below 50�F (10�C) in the "heat" of August. In May and October, temperatures can easily dip below freezing by night and stay below 60�F (15�C) all day. Rainfall fluctuates from month to month, but July and August have the least overcast days (making them the busiest weeks of the summer). Regardless, a stay of several days any time of the summer without at least some rain is uncommon; either bring rain gear or plan on spending time stuck in your tent or a shelter. The good news for people with hayfever is that they'll find few common pollen allergens in the air. (During its resort days, the island was a popular haven for allergy sufferers.) In the winter, conditions are inhospitable and the island is closed to all but wildlife researchers. Even the park headquarters relocate to Houghton for the winter.
