That purple flag flying near the shoreline is not decoration. It carries an important message that can affect how you enjoy the ocean. Unlike green, yellow, or red flags that signal wave and current conditions, purple warns of something different beneath the surface.
A purple flag indicates that potentially harmful marine life has been spotted in the area. This can include jellyfish, stingrays, or other creatures that may sting if touched or disturbed. It’s meant to inform, not alarm.

Seeing a purple flag does not automatically mean the water is closed. Swimming is often still allowed, but extra caution is strongly advised. Awareness is the key purpose of this warning.

Before entering the water, it’s a good idea to talk with the lifeguards on duty. They track ocean conditions throughout the day and can explain what marine life has been seen and where activity is most concentrated.

Simple precautions can greatly reduce risk. When walking into shallow water, shuffling your feet helps alert stingrays so they can swim away. This small habit can prevent painful injuries.

Wearing protective swimwear, such as rash guards, can reduce skin exposure if jellyfish are present. Keeping an eye on children is especially important, as they may not recognize ocean hazards.

Having basic first-aid supplies nearby can also be helpful for treating minor stings quickly. Knowing how to respond calmly makes unexpected encounters less stressful.

Most importantly, respect the flag’s message. The purple flag exists to promote safe enjoyment of the beach. With awareness, guidance, and a few adjustments, the ocean remains a place of confidence—not fear.
