A purple beach flag warns that potentially dangerous marine life, such as jellyfish, stingrays, or Portuguese man-of-war, has been spotted in the water.
It does not necessarily mean you must leave the beach, but swimmers should be cautious and follow lifeguards’ instructions.
Purple flags may appear with green, yellow, or red flags, which indicate the overall level of water and surf hazards.
Understanding the warning system helps beachgoers stay alert, make safer choices, and enjoy the beach responsibly.
