Most people recognize green, yellow, and red beach flags, but the purple flag is less familiar. It warns that potentially dangerous marine life has been spotted in the water or nearby. A purple flag does not always mean the beach is closed or swimming is forbidden. Instead, it is a reminder to stay alert, follow lifeguard instructions, and be careful while enjoying the water.

Jellyfish are among the most common reasons for a purple flag. Their stings can cause pain, redness, and irritation, so never touch one, even if it is lying on the beach. Portuguese man-of-war can also deliver painful stings, and their tentacles may remain dangerous after washing ashore. Stingrays are another concern because they can hide beneath shallow sand. They usually avoid people but may defend themselves if stepped on. In areas where they are common, use the **“stingray shuffle”** by sliding your feet instead of taking normal steps.

Sea lice, which are actually tiny marine larvae, can also cause itching and rashes after contact with the skin. If a purple flag is flying, pay attention to lifeguards and posted warnings. Stay alert while swimming or wading, avoid touching unfamiliar marine animals, and keep children under close supervision. If you are stung or injured, seek help from a lifeguard or medical professional.

A purple flag is not meant to ruin your beach day. It simply warns that marine life may be present and that extra caution is needed. **“Marine life is a natural part of healthy coastal ecosystems,”** so sightings can be completely normal.

By respecting warnings, giving wildlife plenty of space, and staying aware of your surroundings, you can enjoy the ocean while reducing unnecessary risks. The purple flag is there to keep beachgoers informed and safe.
