Even though the summer is still in full swing, many people continue to visit the beaches in our neighborhood. Furthermore, when Labor Day weekend approaches, many people may want to cool off in the pool before enjoying the occasion by leaping into the water. While cooling off in the water is obviously beneficial, we must exercise prudence when doing so.
This is why it’s critical to listen to lifeguards and understand what the different colored beach flags are indicating. Everyone recognizes the red, yellow, and green beach flags. While the ocean is never fully safe, a green flag indicates calm conditions and recommends that you proceed with caution. A yellow flag denotes a medium level of hazard caused by moderate rip currents and/or surf.
The red flag, which indicates the highest level of risk due to heavy surf and/or violent rip currents, appears next. Finally, the double red sign signifies that the water is off-limits to the public. You may have noticed that the United States Lifesaving Association now recommends a different flag color for beach flag signs. Purple is the flag’s color, and it is rarely displayed.
The purple flag is intended to alert beachgoers of harmful marine animals. I know what you’re thinking: “If a purple flag is up, it must mean that a shark was spotted in the area.” The answer is no! According to the USLA, a purple flag really warns of dangerous jellyfish species such as the Man-o-War, which can sting brutally, rather than sharks. It also warns people about a high stingray concentration.
Although stingrays are often afraid of humans, if they feel threatened or are stomped on, they can injure them with their sharp tail. If a shark is seen, lifeguards will raise red or double red flags, indicating that it is unsafe to enter the water. Additionally, beaches may post signs indicating that a shark was spotted in the sand.
However, the presence of purple flags in the air does not mean that swimming is prohibited. Before entering, chat with a lifeguard to learn what to look out for. You should also be mindful of your surroundings and only swim in locations where lifeguards are on duty.
