A purple flag at the beach is not decoration, but a warning that something unusual is present in the water that swimmers should be aware of before going in.

Unlike red or yellow flags that focus on waves and currents, the purple flag specifically signals the possible presence of dangerous or irritating marine life near the shoreline. It may include jellyfish, stingrays, or other sea creatures that can cause painful stings if accidentally touched while swimming or walking in shallow water.
Swimming is often still allowed when a purple flag is flying, but lifeguards recommend extra caution and awareness of where you step and swim.

But what most beachgoers don’t realize is how quickly these marine conditions can change within hours. And a single step in the wrong place can turn a normal beach day into an unexpected emergency.

Lifeguards monitor the water continuously and update warnings throughout the day, especially when marine life activity increases or moves closer to swimming zones. Simple precautions like shuffling your feet in shallow water and avoiding sudden contact with the seabed can significantly reduce the risk of stingray injuries or jellyfish stings.
Staying alert, following lifeguard instructions, and respecting warning flags ensures that beach visits remain safe, enjoyable, and free from preventable accidents.
