Weather & conditions

Isle Royale National Park is a remote island wilderness in the middle of Lake Superior. Weather influences traveling to and from the island, as well as your trip once you arrive. For the most up-to-date weather information, call (906) 482-0984 or email isro_parkinfo@nps.gov prior to your trip.

What this latitude gives you

From 48.0° north, anything above declination +42.0° is circumpolar here: it never sets, so it is available on every clear night of the year. Anything below declination -42.0° never clears the horizon at all.

Full astronomical darkness survives the summer here, but the window is narrow around the solstice. From late August the nights lengthen quickly.

We do not hold a measured Bortle class for this site, so treat the sky as unknown until you have taken a reading of your own.
