Frequently asked questions
What is Vibrio and how can I avoid it?
Vibrio is a type of bacteria that lives in warm seawater. To avoid it, do not swim with open wounds, and avoid eating raw or undercooked shellfish. If you get a cut while in the water, wash it immediately with soap and clean water.
How is the water quality tested at the beach?
Water quality is typically tested for enterococci (a type of fecal indicator bacteria) and sometimes E. coli. Samples are collected and analyzed in a lab. The results help determine if the water is safe for swimming.
What does an ‘advisory’ for water quality mean?
An advisory means that recent tests have shown high levels of bacteria in the water, which can increase your risk of illness. It is recommended to avoid swimming or wading until the advisory is lifted.
Is it safe to swim after it rains?
It is generally recommended to avoid swimming for at least 24-48 hours after heavy rainfall. Rain can wash pollutants and bacteria from the land into the water, temporarily increasing health risks.
What do the different colored lifeguard flags mean?
Green flag: Low hazard, calm conditions. Yellow flag: Medium hazard, moderate surf/currents. Red flag: High hazard, strong surf/currents. Double red flag: Water is closed to the public. Purple flag: Dangerous marine life spotted.
What should I do if I see a jellyfish?
If you see a jellyfish, it’s best to avoid it. Even beached jellyfish can sting. If you are stung, rinse the area with vinegar if available, and carefully remove any tentacles with a towel or tweezers. Seek medical attention if you have a severe reaction.
Are sharks a common threat at Florida beaches?
Shark attacks are very rare. To reduce your risk, avoid swimming at dawn or dusk, don’t swim alone, and avoid wearing shiny jewelry. Most sharks are not interested in humans.
Can I get sick from swallowing beach water?
Yes, swallowing water contaminated with bacteria can cause gastrointestinal illness (stomach cramps, diarrhea, vomiting). Try to avoid swallowing water while swimming.
How can I protect marine life while at the beach?
You can help protect marine life by properly disposing of your trash, not feeding wildlife, and keeping a safe distance from animals like sea turtles and nesting birds. Also, use reef-safe sunscreen to protect coral reefs.
