Important: These are predictions, not official beach flag decisions. Always check the flags currently flying at the beach and follow instructions from lifeguards and local authorities before entering the water.

30A Jellyfish & Purple Flag Conditions

Recent jellyfish sightings and stings have been reported along parts of 30A and nearby Emerald Coast beaches. Jellyfish conditions can change quickly and may vary considerably from one beach to another.

A purple flag indicates dangerous marine life. Jellyfish are one possible reason for a purple flag, but a purple flag does not necessarily mean that jellyfish are present.

Our jellyfish page includes recent community reports and an interactive map covering 30A, Miramar Beach, Destin, Fort Walton Beach, Navarre and nearby Emerald Coast beaches.
