Ask five people on Hilton Head who's in charge of the sea turtles and you'll get five slightly different answers, all pointing at the same beach sweep, the same flagging tape, the same folks in matching shirts working the sand at dawn. Most residents lump it into one operation. It isn't. Sea Turtle Patrol HHI holds the state permit and is the only group legally allowed to touch a nest or a hatchling. Turtle Trackers HHI is a separate, much larger volunteer organization that flattens sandcastles, fills in holes, hands out red-light flashlight filters, and reports the porch lights that are still burning past curfew. If you find something on the beach this week, which one you call actually matters.
That distinction is worth knowing right now because hatching season on Hilton Head runs through October, which means the patrols, the nest inventories, and the lights-out rule are all still active on the same 14 miles of beach residents walk every morning.
The Group With the Permit, and the Group With the Flashlights
Sea Turtle Patrol HHI operates under a South Carolina Department of Natural Resources permit held by Amber Kuehn, who has spent 26 years on nesting beaches from Hilton Head to Fort Lauderdale to Maui. Her team walks the beach starting around 5 a.m. every day from May 1 through the end of hatching season, looking for the tracks a nesting loggerhead leaves behind. When they find a nest, they mark it with a pole and flagging tape, take a DNA sample, and log its GPS position. About half of the season's nests get relocated to higher ground, away from the reach of a king tide, because a nest that floods rarely produces a healthy hatch. This is also the only team permitted to physically handle a nest or a struggling hatchling. If a well-meaning beachgoer digs one up to help it along, that's a problem, not an assist.
Turtle Trackers HHI does something different and just as necessary. The group started in 2016 with a small handful of volunteers in Sea Pines and has since grown to six chapters across the island with more than 350 volunteers. Their work is the nightly "beach sweep," sometimes called putting the beach to bed: clearing forgotten chairs, flattening sandcastles, filling in holes, and checking that nothing on the sand could trip up a turtle heading for the water. They're also the ones staffing the learning stations, running Turtle Talks, and handing out the red cellophane flashlight filters that let you see your own feet at night without disorienting a hatchling.
So the practical version of this is simple. If you see a turtle nesting, a hatch in progress, or an animal that looks distressed, that's a Sea Turtle Patrol situation. If you want to volunteer for a beach sweep, report a stray beach chair, or flag a house that's ignoring the lighting rules, that's Turtle Trackers territory.
This Season Rebounded Hard From Last Year's Slump
The island's own sea turtle season page put the 2025 total at 237 nests, a noticeably light year. Kuehn has attributed dips like that to unusual winter weather that can suppress the food supply female loggerheads need to build up enough body condition to nest, which sometimes pushes a turtle's return interval out by an extra year. Whatever the cause, 2026 came back strong. Reporting from WSAV in early September had the confirmed nest count at 414 for the season, within reach of the all-time record of 463 set back in 2019, with a handful of nests still incubating and the outcome not yet settled.
Emergence success, meaning the share of nests that actually produce hatchlings that make it out of the sand, was running at 74 percent as of that same report, just two points off the best rate the patrol has recorded. Kuehn noted that a stretch of heavy rain earlier in the season was the main variable working against a higher number, since saturated sand can drown eggs or collapse a nest chamber before it ever gets the chance to hatch.
None of this is settled until the last nest finishes, which is exactly why the next few weeks still matter if you're walking the beach at sunrise and wondering what those staked-off patches of sand are for.
The Ordinance That's Still in Effect on Your Own Porch
Beachfront and near-beach homeowners on Hilton Head are required to turn off exterior lights visible from the beach between 10 p.m. and 6 a.m., a rule that stays in effect through the end of October. Blinds and drapes facing the water are supposed to stay closed during those hours too. The reasoning is straightforward: hatchlings navigate by moving toward the brightest light on the horizon, which is supposed to be the moon reflecting off the ocean. A bright porch light or an uncovered window can pull them the wrong way entirely, sending them toward a road instead of the surf.
Violations get reported to the Town of Hilton Head Island's Code Enforcement Officers at 843-341-4643, and Turtle Trackers volunteers are often the ones who spot the problem first during their nightly sweeps. This isn't a rule aimed at vacation renters who don't know the island. It applies to anyone with a house that faces the sand, and it's still active tonight.
What a False Crawl Actually Means
A false crawl is what patrol volunteers call it when a nesting turtle comes ashore, gets partway through the process, and turns back to the ocean without laying eggs. Lights, an unexpected obstacle like a sandcastle or a forgotten cooler, or simply too much activity on the beach can all trigger one. It's a wasted trip for an animal that may not attempt to nest again that season, which is part of why the lights-out rule and the nightly sweeps aren't just symbolic.
If you're on the beach after dark and come across a nest that's hatching, the guidance is consistent across every source on this: keep your distance, use a red-light flashlight if you have one, and don't touch the hatchlings even if one looks stuck. Sea Turtle Patrol's team handles physical intervention. Everyone else's job is to stay back and stay dark.
There's a detail in the incubation process that even longtime residents often don't know. The temperature of the sand around the eggs determines the sex of the hatchlings, with nests that stay below roughly 82 degrees Fahrenheit producing males and warmer nests producing females. It means the same beach that residents walk every August is quietly deciding, degree by degree, what the next generation of loggerheads looks like.
Myrtle, and the Weeks Still Ahead
If you've driven past Park Plaza, the Hilton Head Airport, or The Sandbox Children's Museum, you've likely seen the turtle sculpture painted by local artist Mira Scott. It's modeled on a real, repeat-nesting loggerhead named Myrtle, who has been coming back to Hilton Head's beaches since 2011. Most female loggerheads take a couple of years off between nesting seasons. Myrtle doesn't. She laid eight nests in 2017 alone, the most ever recorded for a single turtle on the island in one season, and at an estimated 60-plus years old, she's still out there most years.
Hatching season doesn't wrap until the end of October, which means there's still a real chance to catch a nest emerging if you're on the beach early enough or out for a walk after the sun goes down. The staked nests you've been stepping around all summer are still doing their work. Keep the porch light off after ten, and if you see something moving in the sand, call the patrol before you call anyone else.
If you're getting to know the rhythms of Hilton Head Island beyond the beach and want to talk through what life here actually looks like season to season, Michael Sutcliffe is a good place to start that conversation.
