Know the Flags: An Emerald Coast Guide to Beach Warnings and Rip Currents
EMERALD COAST – A calm-looking Gulf can still contain a fast-moving rip current. Before entering the water, check the flags posted by local beach patrol and the day’s surf forecast. The two systems work together: the National Weather Service issues a rip-current outlook, while local officials post flags for conditions observed at the beach.
What the flags mean
- Green: Low hazard. Conditions may be calmer, but ordinary caution is still required and rip currents can still occur.
- Yellow: Medium hazard. Moderate surf or currents are present; weak swimmers should stay out of the water.
- Single red: High hazard. Strong surf or currents make conditions dangerous.
- Double red: Water closed to the public. Entering the Gulf can lead to a citation or arrest.
- Purple: Dangerous marine life. This flag can fly with another color and does not describe surf conditions by itself.
No flag does not mean no danger. Not every access point is staffed, and conditions can change between flag updates. The National Weather Service’s local rip-current guidance recommends checking the forecast, looking for posted warnings, asking a lifeguard, and swimming near guarded areas whenever possible.
How a rip current works
A rip current is a concentrated flow of water moving away from shore. It does not pull a swimmer under, but it can carry someone away from the beach quickly. Channels of darker or choppier water, fewer breaking waves, or foam moving seaward can be clues, but rip currents are not always easy to see.
Sunny weather is not proof of safe swimming. Swell from a distant storm can create hazardous currents long after the storm itself has moved away.
If you are caught in one
- Stay as calm as possible and conserve energy. A rip current carries you away from shore; it does not drag you beneath the water.
- Do not exhaust yourself fighting directly against the current.
- If you can, swim parallel to the shoreline until you are out of the current, then angle back toward the beach.
- If you cannot escape, float or tread water and signal for help by waving and calling out.
If someone else is in trouble
Alert a lifeguard or call 911. Throw the person a flotation device and tell them to swim parallel to shore. Entering the water without rescue training can turn one victim into two; many would-be rescuers drown while trying to help.
A five-second beach check
- Check the local surf and rip-current forecast.
- Read the flags at the access point.
- Locate the nearest lifeguard and emergency marker.
- Keep children within arm’s reach near the water.
- When in doubt, stay out.
