A purple flag flying at the shoreline is increasingly being used by lifeguards as a warning that potentially hazardous marine life has been spotted in the area.
Unlike full beach closures, the signal does not mean the water is off-limits. Instead, it indicates that conditions may be less predictable than usual, with the possible presence of jellyfish, stingrays, or other stinging or irritating sea creatures.
Lifeguards say the flag is intended to prompt greater awareness rather than alarm. Swimmers are encouraged to take extra precautions, stay close to supervised areas, and pay attention to local guidance about where marine activity has been observed.
Beach safety officials note that simple measures—such as avoiding dragging feet in shallow water, wearing protective swimwear, supervising children closely, and carrying basic first aid supplies—can significantly reduce the risk of injury.
The system is designed to support continued beach use while improving safety. In that sense, the purple flag serves as a reminder that ocean conditions can change quickly, and that caution is part of enjoying the water responsibly.
