If you’ve been to a number of beaches in a number of states, you’ve noticed that there are differing flag warning systems in place. It can seem pretty confusing! The State of Florida has one uniform beach flag warning system for the entire Sunshine State, encompassing both the Atlantic and Gulf coasts. Chicago, Illinois has its own system of colors for beach warning flags covering their 33 beaches on the shores of Lake Michigan. Galveston Island, Texas has yet another set of flag colors for its 32 miles of beaches on the Gulf of Mexico.

It’s a good policy to check out the beach flag warning system online before you head for the beach. But, if the beach you are visiting is protected by a lifeguard patrol, you should be able to find the color key to their beach flag system displayed at or near the lifeguard tower(s) and possibly near the beach’s access points.
We found this past weekend that Galveston beaches display their colors prominently along the famous Seawall. The Galveston Island Beach Patrol also flies their own banner on each tower, indicating that a lifeguard is on duty.
