Forecast pending.
Which night hours are most promising?
Hourly scoring uses NWS cloud-cover data, astronomical darkness, the approximate moon position, and the leading active shower radiant. Tap an hour for an explanation.
Can I enter and observe legally?
Arrange island transportation and verify wildlife-area rules; this coordinate is an area reference.
Island sanctuary; ferry or air access and specific wildlife-area rules apply.
Official park or designation source ↗
A site’s certification is not an entrance permit. Check opening hours, seasonal closures, campground access and road plowing before travel.
What makes this place special?
International Dark Sky Sanctuary on an island in northern Lake Michigan.
A sky forecast does not establish ferry, flight, trail, lodging or sanctuary access.
What might I see?
Year-round there can be sporadic meteors and bright celestial objects. Major meteor showers, the Milky Way and the northern lights require the right season and environmental conditions. None is guaranteed by dark-sky designation.

Map pins represent park areas, not official entrances, parking areas, safe viewing sites or travel routes. Green = International Dark Sky Places; blue = other designated preserves; purple = certified community; gold = selected site or approximate device position.
CARTO Voyager uses the public Vercel basemap key, with an OpenStreetMap fallback. Always check the actual park operator for safe and lawful entry.
