Florida uses a uniform flag warning system: green, yellow, red, double red and purple. On Amelia Island the most common state is no flag at all, because most of the thirteen miles of beach is unguarded — which is not the same as safe.
Fernandina Beach's busiest and most amenity-heavy oceanfront park, at the east end of Atlantic Avenue. Large free parking lot, restrooms, playground, volleyball, and food and mini-golf across the street — the default choice for a family beach day on Amelia Island.
Nassau County's largest south-end beach park, off Fletcher Avenue near Sadler Road's southern reach. Big free lot, restrooms, outdoor showers, picnic pavilions and a long boardwalk over the dunes — the south end's answer to Main Beach, usually with more room.
Details unconfirmed
A Nassau County beach park at American Beach on the island's south end, with a free lot, restrooms, picnic pavilions and a dune walkover. The practical parking and facilities for anyone visiting American Beach and the NaNa dune.
A compact City of Fernandina Beach oceanfront park at the east end of Sadler Road, with a free lot, restrooms, a dune boardwalk and a small playground. The closest full-facility beach to the middle of the island and the usual overflow from Main Beach.
The stretch of Amelia Island shoreline north of Main Beach toward the Fort Clinch jetties, reached from the northern Fletcher Avenue accesses. Wide, quiet sand with a working-port view, no facilities, and the island's strongest currents near the jetties.
Roughly two dozen small public beach accesses spaced along South and North Fletcher Avenue in Fernandina Beach, most with a dune walkover and a handful of roadside spaces and nothing else. The way onto the sand if you are staying oceanside.
Details unconfirmed
A small Nassau County beach access off Scott Road on the island's oceanside, with a modest free lot and a dune walkover but no restrooms or showers. One of the accesses used for permitted beach driving.
Details unconfirmed
Two hundred undeveloped acres at the island's southern tip on Nassau Sound: beach, dune, marsh and maritime forest, with no buildings and no lifeguards. The only Florida state park offering guided horseback riding on the beach.
Two beaches inside Fort Clinch State Park at Amelia Island's northern tip: Atlantic surf on the east side and calmer water by the jetties on the north, plus a fishing pier looking across Cumberland Sound to Georgia. Inside the park entry fee.

Florida beaches use a uniform colour system. Where a flag is flying it is the authority — not a forecast, not a buoy reading, and not this page.
| Flag | What it means |
|---|---|
| Green | Low hazard. Calm conditions — still exercise caution. |
| Yellow | Medium hazard. Moderate surf or currents. |
| Red | High hazard. High surf or strong currents. |
| Double red | Water closed to the public. |
| Purple | Dangerous marine life reported. Flown alongside a condition flag, not instead of one. |
Purple does not mean sharks. It covers jellyfish, man o' war and similar — the things that make swimming unpleasant or painful rather than the things people imagine.
This is the part that matters on this island. Most of the thirteen miles of beach has no flag and no lifeguard, at any time of year.
Main Beach Park is the only access we have confirmed carries seasonal lifeguards. The numbered Fletcher Avenue accesses — how most visitors actually get onto the sand — have neither. Where our beach records say a field is unconfirmed, it is unconfirmed; we do not fill it in.
No flag is not a green flag. It means nobody is assessing the water. Judge it yourself, and default to caution.
Three bodies run this one beach, which is why answers seem to contradict each other:
If you need a definitive answer on flags or rescue cover for a specific access, the responsible body above is the source. We have not confirmed every access against every one of them, and we say so rather than guessing.
Rip currents. A 6 to 7.4 ft tidal range pushes a lot of water out through gaps in the sandbar system, and a falling tide with surf running is the classic setup. If you are caught, swim parallel to the beach rather than against the pull. The mechanism and what to do are on our rip currents page, and it is the more important of these two pages.
The tide. A 6–7 ft range on a very flat beach means the sandbars you wade at dead low are surrounded by moving water on the flood — and it comes in behind you, not at you. Today's tides.
Heat. July averages 90.7°F with humidity to match, and there is no shade on the beach. More water than you think.
Sun. Nothing on this coast blocks it.
Lightning. Afternoon thunderstorms are near-daily from June to September. Off the water and off the sand when you hear it.
Sea turtles. Nesting season runs 1 May to 31 October: fill in holes, take gear off the beach overnight, lights off the sand. The rules are enforced. See sea turtles.
Beach driving. Permitted at designated ramps in Nassau County and a low-tide activity. Rules and permits are the county's — see driving on the beach.
Our beach conditions page carries the flag as a manually maintained field with a timestamp, because there is no official machine-readable feed for it and we will not pretend otherwise. For the day's actual flag, look at the pole.
