Before entering the water, it’s important to note what color flag is flying near the shore. The flags are there to alert us to the condition of the water. They inform us regarding whether it’s safe to swim, including warnings of marine pests. The United States Lifesaving Association and the International Lifesaving Federation developed a flag warning system to inform swimmers of water hazards. Below is the definition of each so you will know the meaning on your next beach trip.
Yellow Flag Meaning: Medium hazard
Moderate surf and/or currents are present. Weak swimmers are discouraged from entering the water. Greater care and caution should be carried out.
Red Flag Meaning: High hazard
Rough conditions such as strong surf and/or currents are present. Swimmers are discouraged from entering the water. Those entering the water should take extreme care.
Double Red Flag Meaning: Water is closed to public use
Dangerous conditions make it unsafe to be in the water.
Purple Flag Meaning: Marine pests present
Jellyfish, stingrays, sea snakes or other marine life are present in the water, and can cause injuries.
Red Over Yellow Flag Meaning: Recommended swimming area with lifeguard supervision
The area is protected by lifeguards.
Keep in mind that even with a medium hazard, everyone should use caution and common sense when entering the water. Practicing beach and water safety will allow you to return home with wonderful memories as you look forward to your next visit.
