The coasts of the Caribbean are indeed paradisiacal and picture perfect; however, they are no stranger to winds or unwelcome weather conditions. As preventive measures, the beaches will inform swimmers about the conditions of the water using the flags mechanism.
We have the meaning of the warning flags you may encounter.
Red Flag: Danger warning level, dangerous conditions prevalent, swim with extreme cautions. In some destinations, the red color also means swimming is prohibited.
Yellow Flag: Cautionary warning, swim but do so with caution.
Green Flag: Conditions are safe for swimming.
Blue Flag: It’s a certification, present where the beach has met excellent health standards.
Privilege Tip: Swimming against the current can tire you quickly. If you’re ever going to catch a rip tide, try to swim parallel to the coast to less aggressive currents.
