About Grand Marais Bay Beach

A sandy town beach inside protected Grand Marais Bay.

How to read this page

The Beach Day Score compares day-trip potential, not whether entering the water is appropriate. It is N/A unless the required weather values and both water temperature and wave height are present, with the NOAA observation no more than six hours old. Daily ranking also requires explicit low NWS swim risk and no matched official alert. Open the named sources, judge the station distance, and reassess the posted flag and shoreline conditions when you arrive.
