2,421 nests on 13 Lowcountry beaches, and the hatchlings are running
The state’s monitoring database has 2,421 sea turtle nests on the coast this season, from Kiawah Island at 496 down to Sullivan’s Island at 17, and the early nests are hatching.
South Carolina’s nest monitoring database counts 2,421 sea turtle nests on the thirteen monitored beaches between Daufuskie Island and Sullivan’s Island this season. Kiawah Island is carrying 496 of them. Sullivan’s Island has 17. The nests laid in May are coming up now.
A nest empties in a rush, which is why the people who watch them call it a boil. Sea Turtle Patrol HHI caught one on Hilton Head in the morning, which is the less usual version, because nests normally go after dark when the sand has cooled.
Kiawah is carrying more nests than anywhere else on the coast, and the season there runs from nesting females in early summer to hatchlings now.
Here is every monitored beach, from the live database. Nobody else puts them in one place.

Each of those rows starts as one female coming ashore at night and digging above the dune line. Volunteers find the crawl the next morning, mark the nest and count what is in it.
About sixty days later the nest goes. Once it does, SCDNR requires three days before anyone digs it out, so that the stragglers get out on their own. Only then does permitted patrol staff run the final inventory.
Those inventories are done in the open and people watch them.
An inventory turns up hatchlings that never made it out of the chamber. This one had a lot of them still to come.
The one thing that matters if you are on the beach at night is light. Hatchlings find the water by heading for the brightest part of the horizon, which under a natural sky is the ocean reflecting blue and green. A porch light, a flashlight or a camera flash beats the ocean and the hatchlings go inland instead. The Department of Natural Resources calls it disorientation, and it kills them: they burn the energy they need for the swim offshore and end up on open sand where predators find them.
The rule the patrols ask for is red light only, never white. SCDNR asks beachfront households to keep exterior lights off from dusk to dawn between May and October, and to close blinds where interior light reaches the sand. Hatching runs to the end of October, so the database totals above will be higher by the time the season closes.
