Flag Color	Meaning
Green	Indicates that conditions are calm. Swim with care.
Yellow	Indicates caution should be used when entering any body of water. This flag is flown for normal conditions to remind swimmers to stay alert.

Purple	Indicates a potential problem with jellyfish, Portuguese man-o-war, stingrays or other marine life that could be a hazard for swimmers. Purple flags will be used in combination with other flags.
Orange	Indicates there is an environmental warning for air and/or water quality. Orange pennant flags will be used in combination with other flags. Check Texas Beach Watch for more details.

Seaweed

Every year, the Texas coastline and the Gulf of Mexico are affected by sargassum landings. Sargassum is a type of brown seaweed that originates in the Sargasso Sea, a region of the North Atlantic Ocean, and travels the Atlantic by currents. The Gulf of Mexico and the Caribbean Sea often see the results of sargassum blooms when the seaweed makes landing on the beaches in these areas. Warm water and extra nutrients cause larger blooms of sargassum, creating large free-floating mats.

Sargassum Management Guidelines

Did You Know?

County regulations only permit the removal of sargassum when it accumulates to at least 8 feet wide and 6 inches high perpendicular to the shoreline. This policy helps protect the marine ecosystem and supports natural dune formation.

Two of the main players that change water’s color from its clear state to a darker alternative are sediment and organic material. Organic materials, such as phytoplankton, often turn water various shades of green. Sediment often turns the water a darker color, ranging from murky black to coffee brown or lighter shades of brown or yellow.

Real-Time Beach Watch Advisories

The Galveston County Health District, in conjunction with the Texas General Land Office (GLO), monitors recreational coastal waters for elevated levels of the bacterial indicator enterococcus. A beach water advisory is issued for the beach adjacent to the testing site when water quality standards for the bacteria are exceeded. The Galveston County Beach Watch program samples 52 monitoring stations along Galveston Island, the Bolivar Peninsula and one site on the Texas City Dike.
