Decoding Michigan’s Beach Flags: Knowing Could Save Your Life

Michigan's beaches are about to get crowded, and according to the Michigan Department of Natural Resources (DNR), there are two things every beachgoer should understand before charging into the Great Lakes like they're a backyard kiddie pool.

Michigan Beach Flag Warnings Explained

Upon pulling up to a beach in Michigan, you may notice a flag flying near the entrance. That's not meant to draw attention to the beach, but rather to give you a heads-up on what kind of water conditions you're getting ready to plunge into.

• Green Flag: Low hazard. Swimming conditions are generally safe.
• Yellow Flag: Medium hazard. Stronger waves or currents may be present. Use caution.
• Red Flag: High hazard. Dangerous swimming conditions exist.
• Double Red Flag: Water access is closed. Swimming is illegal, except for certain surfers who enter at their own risk.

The DNR says visitors should always check the flags before entering the water because, as with Michigan weather, conditions on the Great Lakes can change quickly.

Why Michigan Wants You Inside Buoyed Swim Areas

White buoys marking a swimming area are seen floating in the water.

Those ropes and floating buoys aren't there to ruin your cannonball plans. Buoyed swimming areas help keep swimmers away from dangerous currents, especially near piers, breakwalls, and river outlets. DNR crews regularly inspect and adjust these areas as water conditions change.

The Great Lakes Demand Respect

Keep in mind that not every state park in Michigan has buoyed swimming areas, but when one is available, it is the safest place to swim. Here are a few more reminders to keep you and your family safe on Great Lakes beaches:

• Never swim alone.
• Keep children within arm's reach.
• Use Coast Guard-approved life jackets.
• Stay away from piers during rough water.
• Don't underestimate cold water, even on hot days.

The Great Lakes contain more than 20% of the world's fresh surface water. They're beautiful, powerful, and occasionally very good at reminding us who's really in charge.
