That purple flag isn’t decoration—it’s a warning that marine pests like jellyfish, stingrays, or other stinging creatures may be in the water. It doesn’t always mean you must stay out, but it does mean caution: check with lifeguards, know what’s been spotted, and take simple precautions like shuffling your feet and watching children closely. Respecting the purple flag helps keep a great beach day from turning into an emergency.
