Season calendar
Apostle Islands Archipelago by month
Best months, permit windows and published seasonal conditions in one view. Every band comes from this destination’s verified agency sources — months with nothing published say so.
September
Best season- Autumn · September – October
- Gale season: fast-building high-wind events and cold rain. Beautiful, but serious.
Permits
A wilderness camping permit is required for every overnight stay in the national lakeshore, reserved in advance through Recreation.gov. Day paddling the mainland caves needs no permit, but every island night does.
