"May the wings of the butterfly kiss the sun And find your shoulder to light on, To bring you luck, happiness and riches Today, tomorrow and beyond."~Irish Blessing
Beach Flags are essential to having a good as well as safe time. A green flag means low hazard. It is the best conditions to go swimming, or build sandcastles right next to the water. A yellow flag is moderate surf and/or currents.
A single red flag has strong waves and a high surf and/or currents. A double rag flag means that the beach is closed to the public. Don't swim alone when these flags are up.
A purple flag means dangerous marine life such as sharks, jellyfish, and many others.
Also, in case of a jellyfish sting, avoid putting fresh water on the injured area; pour vinegar and use a credit card to scrape the tentacle fragment from the skin.
