Beach warning flags on Anna Maria Island give you the quickest read on Gulf conditions before you get in the water. The flag at the nearest lifeguard tower reflects the surf and current at that moment, and conditions can shift between morning and afternoon. This guide explains what each color means, where the flags are posted, and what to do on days when swimming is not a good idea.
Beach Warning Flag Colors
| Flag Color | Meaning | What You Should Do |
|---|---|---|
| Green | Low hazard | Safe to swim, stay alert |
| Yellow | Medium hazard | Swim cautiously |
| Red | High hazard | Strong currents, avoid swimming |
| Double Red | Water closed | Do not enter water |
| Purple | Marine pests | Watch for jellyfish, stingrays |
Florida uses a uniform flag system, so each color means the same thing at every guarded public beach in the state. Flags fly at the lifeguard towers, usually next to a sign that explains each color.
Where to Find the Flags
Flags are posted at all 11 staffed lifeguard towers on the island. Tower 1 sits at Manatee Public Beach in Holmes Beach. The other ten are spread across Coquina Beach and Cortez Beach in Bradenton Beach. Lifeguard hours change by season, so check Manatee County’s beach conditions page for the current day before you head out.
The north end of the island, including Bean Point and Bayfront Park Beach, has no lifeguards and no flags. If you swim there, watch the waves, the current, and the weather for a few minutes before you go in.
Warning Flags Origin
Surf and water conditions can change quickly on Florida’s Gulf Coast, which is why the state uses a standardized beach warning flag system to keep visitors informed and safe. These color-coded flags were officially adopted across all public beaches to eliminate confusion and provide clear, consistent safety signals no matter where you are along the coastline.
Practical Beach Safety Tips
Understanding beach warning flags is the first step but knowing how to respond to changing conditions is just as important.
Rip Currents
Rip currents are one of the most common hazards along the Gulf Coast and they can form on days when the water looks fairly calm. If one pulls you out, stay calm and do not fight it. Swim parallel to the shore until you are out of the current, then angle back to the beach.
Free Life Vests on the North End
Manatee County’s Beach Like a Local program offers free, borrow-and-return U.S. Coast Guard approved life vests in sizes from infant to adult. You will find them at Bayfront Park and along Gulf Boulevard between Magnolia Avenue and Palm Avenue. Return the vest to the stand when you finish.
Never Ignore a Double Red Flag
A double red flag means the water is closed to the public. Conditions are too dangerous for swimming, and this is not a suggestion.
Swim Near a Lifeguard
A staffed tower is the safest place to swim, especially under a yellow or red flag. Lifeguards watch the water all day and respond quickly when conditions change. My Lifeguard Stations on Anna Maria Island: My Insider Guide covers exact locations, hours, and the best beaches to choose.
Watch for Marine Life
When the purple flag is up, jellyfish or stingrays may be in the water. Shuffle your feet as you wade in so you do not startle a stingray and keep an eye out for anything moving near you.
When in Doubt, Stay Out
If you are unsure about the conditions, stay on the sand. The island has plenty to offer on a high-hazard day. And if the weather keeps you off the water altogether, check out my Rainy Day Activities on Anna Maria Island: My Insider Guide for plenty of ideas to keep you busy until it is safe to go in the water.
Alternative Activities
When red or double red flags are flying on Anna Maria Island, it simply means it is time to enjoy the island in a different way.
By Bike or on Foot
Breezy days are good for exploring beyond the beach. Rent a bike and ride the quiet streets and coastal paths with my Biking on Anna Maria Island: My Insider Guide. Then walk Bridge Street for shops, waterfront restaurants, and views, using my Bridge Street on Anna Maria Island: My Insider Guide.
Drinks, Games, and Music
A rough water day is a good excuse to settle into the island’s social side. Find a waterfront happy hour, try the beach bar games, or plan an evening around live music.
Relax and Recharge
Book a couples massage, take a walk with birdwatching tips, or try something unexpected like mahjong on the island.
