Last Updated on June 30, 2025 by Megan

When visiting Cancun, understanding Cancun beach safety flags is crucial for a safe and enjoyable beach experience. These colored flags are important indicators of ocean conditions, helping to ensure swimmer safety. Here’s an explanation of the different Cancun beach safety flags you may see and what each one means:
Green Flag – Safe Conditions
Meaning: A green flag on the beach indicates that ocean conditions are generally safe for swimming. The water is calm, with minimal currents or hazards. However, it’s still important to exercise caution, especially for inexperienced swimmers or children.
Yellow Flag – Caution Advised
Meaning: The yellow flag signals caution. Swimming is allowed, but conditions are not completely calm. Moderate currents or waves may be present. Swimmers should be cautious, and weaker swimmers or children should stay close to shore or be supervised.

Red Flag – Dangerous Conditions
Meaning: A red flag represents hazardous water conditions. Strong currents, high waves, or other dangerous conditions make swimming risky. Only strong swimmers should enter the water, and even then, with extreme caution.
Double Red Flags – Water Closed
Meaning: Double red flags mean that the ocean is closed to the public due to extremely dangerous conditions such as severe rip currents, high surf, or severe weather. Swimming is strictly prohibited, and entering the water can be life-threatening.
Purple Flag – Marine Life Warning
Meaning: The purple flag warns of potentially dangerous marine life, such as jellyfish, stingrays, or other creatures that could pose a threat. Swimming is allowed, but caution is advised, and it’s important to be aware of your surroundings.
Black Flag – Extremely Hazardous Conditions
Meaning: Although not commonly seen, a black flag may indicate extremely hazardous conditions due to poor visibility, high winds, or rough surf. Water activities should be avoided when this flag is displayed.
