As we enter the hottest days of the year - rolling on through Labor Day weekend and beyond - our beaches become cool havens from the searing sun. But the water, as refreshing as it is, must always be treated with respect and caution.
To that end, many beaches have adopted a warning system that informs beachgoers of current water conditions. Solid color flags are posted to indicate water, surf and dangerous marine life. It is important - in some cases, life-saving - to pay attention to those flags. The goal is to make swimming a pleasant, safe activity - and keep you alive.
A green flag means the water and current are calm and swimming conditions are ideal. Jump right in, the water doesn't get any better than this! But still, lifeguards warn, use caution and always swim with care.
A yellow flag (some beaches use orange) indicates a moderate surf and current. Conditions for swimming are still good, but it is necessary to use extreme care. Be vigilant, always treat the ocean with respect and realize conditions change rapidly.
A red flag is flown when conditions are determined to be out of the ordinary, such as presence of strong wind, strong current or large surf. Adult swimmers should stay in the water no more than waist deep and non-swimmers and children should be kept along the surf line. And do not get bold and believe you can handle difficult conditions. Even strong swimmers have gotten in trouble and had to be rescued or have drowned.
A double red flag means the water is officially closed. It is against the law to go into the water when a double red flag is posted. If you do, you are subject to arrest and fine.
A purple flag indicates dangerous marine life. This includes sharks, Portuguese Man of War, stingrays and jellyfish. Unless you want to get stung or worse, stay out of the water.
Warning flags are an effective method to understand water conditions and keep safe. Lifeguards monitor the water and change flags when necessary. They also recommend using common sense when you enter the water. Do not swim alone or when intoxicated, they warn, and try to swim near lifeguard stations so that if you do get in trouble, professional help will be seconds away.
