Michigan summers and beach days go hand-in-hand but not every seeming oasis is a safe place to dip your toes.

Before packing a cooler, towels, sand toys and an umbrella and heading to your local beach, check this list of 14 beaches that, as of Thursday afternoon, July 22, are closed or under contamination advisories for high bacteria levels.

The notifications are made as part of the Michigan Department of Environment, Great Lakes and Energy’s Beach Guard system. Each beach’s status is subject to change as new test results come in.
