Every one of Amelia Island's thirteen miles of Atlantic beach is potential sea turtle nesting habitat, and for about half the year it is in active use.
The season
Nesting on this coast runs from roughly May through October, with nesting concentrated in the earlier months and hatching in the later ones. Exact dates are set by the state and vary slightly by region — the Florida Fish and Wildlife Conservation Commission publishes the authoritative window and we have not confirmed the current one, so check FWC directly.
Loggerheads are the most common nesting species on Florida's Atlantic coast. Greens and leatherbacks also nest here in smaller numbers.
What a nest looks like
Usually, a marked area: staked and taped, with a sign, surveyed by permitted volunteers who walk the beach at dawn through the season.
Unmarked, a fresh nest reads as a wide disturbed patch of sand above the high-water line with crawl tracks running up from the water and back — like the tracks of a small tractor tyre.
If you find an unmarked nest or a crawl, do not touch anything. Report it. Nassau County and FWC have reporting routes; the beach patrol or the state park staff will know.
The rules, and why each one exists
Fill in every hole you dig. A hole is a trap. A nesting female that falls into one may not get out, and a hatchling certainly will not. This applies to the small ones a child dug as much as the pit someone dug for a fire.
Take everything off the sand at the end of the day. Chairs, umbrellas, tents, coolers, toys. Furniture left overnight is an obstacle course between a nest and the water, and hatchlings do not go around things well.
Stay off marked nests, and keep back from the dune line generally.
Keep dogs leashed and away from the dune. A loose dog on a nesting beach is a wildlife offence, not a minor infraction. There is no off-leash beach on Amelia Island in any case.
Shield lights. This is the one visitors in oceanfront rentals get wrong. Hatchlings orient toward the brightest horizon, which should be the moonlit ocean. A lit balcony, an open blind, or a torch on the beach sends them inland, where they die. Close blinds after dark, turn off what you can, and if you must use a light on the beach use a red or amber one.
No flash photography of turtles or hatchlings, and no flying drones over the beach during the season.
If you see a nesting turtle
Stay well back, stay quiet, stay behind her, and use no light. A disturbed female will abandon a nesting attempt and return to the water. Do not touch her, do not get in front of her, and do not let anyone else.
If you see hatchlings
Let them go. Do not pick them up, do not carry them to the water, and do not "help" — the crawl to the sea is part of how they orient and build strength. Keep people and dogs away, remove obstacles from their path if you can do so without touching them, and turn off any light.
Where to learn more
The Omni Amelia Island Resort nature centre runs ecology programming on the south end, and volunteer turtle patrol groups operate along the island's beaches. FWC's sea turtle pages are the authoritative source for season dates, species and reporting routes.
Also protected here, in winter
North Atlantic right whales calve off this stretch of coast in winter, which is why the offshore waters are federally protected in season. You will not see one from the beach reliably, and the November Right Whale Festival exists to mark it. Vessel approach rules are strict and federally enforced.
