The flags on the beach are color-coded and used to communicate different messages and warnings to beach-goers. Here is what each flag color usually indicates:

1. Red Flag – A red flag on the beach indicates that the water is closed to swimmers due to dangerous conditions, such as strong currents, high surf, or lightning.

2. Yellow Flag – A yellow flag indicates that swimmers should exercise caution when entering the water, as there may be moderate surf and/or currents.

3. Green Flag – A green flag indicates that the water is calm and safe for swimming, although this doesn’t necessarily mean that there aren’t any risks involved.

4. Purple Flag – A purple flag indicates that there may be dangerous marine life, such as jellyfish or sharks, in the water. It’s important for beach-goers to always pay attention to the flag warnings and follow the instructions of lifeguards or other beach officials.

Additionally, it’s always recommended to swim in areas where there are lifeguards on duty, and to never swim alone
