The Flag Warning System is used to advise beach patrons of the current water conditions and any applicable environmental warnings. The flag colors described below are part of a national system employed to help beach-goers understand the current conditions in the always dynamic environment of open water.
On Galveston Island, informational signs and warning flags are posted each day along Seawall Blvd. at 61st St., 53rd St., 37th St., 29th St., and 10th St. During the summer months, each guarded Lifeguard Tower flies the appropriate flags for the day. All Park Board operated parks, such as East Beach, Stewart Beach and the West End Pocket Parks, also display the warning flags when the parks are open.
Galveston Island Beach Patrol employs a notification system that displays the day’s warning flags, along with any specific advisories for the day, on our Homepage. Interested parties may also sign up to receive the notifications via email and/or text message daily.
