Sea Turtle Nesting Season on Gulf Beaches

May to October on our wild beaches — the season of crawls, nests and hatchlings.

From May through October our barrier-island beaches become a nursery. You won't usually catch a turtle in the act — that's a nighttime thing — but you'll read the whole story in the sand: wide crawls, roped-off nests, and late-summer trails of hatchling tracks racing for the surf. Here's how the season works and how to share the beach the right way.

Short answer: Sea turtle nesting season on Florida's Gulf coast runs May through October, with loggerheads doing nearly all the nesting on boat-only beaches like Keewaydin, Kice and Cape Romano. On a daytime tour you'll see evidence — wide tractor-tread crawls and roped, staked nests — not nesting turtles, which come ashore at night. The rules are simple: stay back, keep lights out, and never disturb a nest.

The season timeline

Nesting kicks off in May as the first females haul out, builds to a peak in the heart of summer, and tapers into October. Hatching overlaps the back half: roughly two months after a nest is laid, the eggs hatch and the babies scramble to the Gulf, so from late summer into fall you can find both fresh nests and tiny hatchling tracks on the same beach. The loggerhead does nearly all of it here, with the occasional green or Kemp's ridley mixed in. For how nesting fits the wider calendar, see our wildlife-by-season guide.

What you'll actually see on a tour

Set expectations: turtles nest under cover of dark, so a daytime tour shows you their signs, not the animals. The classic is the crawl — a wide, symmetrical drag mark, like tractor treads, running from the surf up to the nest and back. Near the top you'll find the nest itself, usually roped and staked by survey teams, sometimes with a small marker. Late in the season look for the delicate scatter of hatchling tracks fanning down to the water. On our shelling tours to beaches like Keewaydin and Cape Romano, our captains read these stories in the sand for you.

Conservation etiquette

These nests are protected and fragile, so a few simple habits matter. Stay well outside any roped nest and never walk on a crawl. Before you leave a beach, fill in holes and flatten sandcastles — a hatchling can get trapped in a hole or lost behind a sand wall. If you're on the islands at night during the season, lights-out is the golden rule: artificial light disorients nesting females and hatchlings and steers them away from the Gulf. We cover the full code on our wildlife viewing etiquette page, and we live it on every wildlife tour we run.

From the Helm: Reading Panther Key’s wrack line at first light before the wind erases it

Before we ever leave the dock during nesting season, the overnight wind forecast decides part of our route. A hard onshore blow through the night can wipe a fresh crawl off Panther Key’s gulf beach by mid-morning, so on those mornings we’ll swing past there early in the run rather than save it for later, while the sand still holds whatever came ashore overnight. On calmer nights, the tracks tend to hold longer and we’ve got more flexibility in when we pass. We’ll also glance at the moon phase before committing to a route, since a spring tide pushes water higher up the beach face and can bury or erase a crawl faster than an ordinary tide would.

Not every track we point out ends in a nest. Sometimes a turtle comes up, gets partway across the beach, and turns back to the water without digging — what we call a false crawl — and the track just stops and doubles back on itself instead of ending at a mound of disturbed sand. We’ll call that distinction out for guests because it’s a small thing that changes how you read the whole beach, and it’s honestly no less interesting than a successful nest.

We time the pass for the tail end of a falling tide when we can, because the wet sand right at the wrack line holds a crisp track far better than sand that’s already dried out above the last high-water mark. If we get to that stretch after the water’s already started rising again, we won’t linger trying to force a good look — we’ll keep the run moving and let the beach do what it’s going to do without us circling back for it. We also hold the boat further offshore on this pass than we would otherwise, trading a slightly longer look through binoculars for a route that never puts our wake anywhere near the nesting beach itself.

From the boat, what you notice first is scale — a loggerhead’s crawl is wide enough that it genuinely surprises people the first time they see one, wider than most guests picture a turtle needing. We keep our distance and our speed down along that stretch, both because it’s the right way to run a nesting beach and because slower water gives everyone on board time to actually spot the track before we’re past it.

None of this puts an actual turtle in front of you during daylight — they nest at night and we respect that distance completely — but the evidence itself tells a real story if you know what you’re looking at. These are the same boat-only beaches we run for shelling the rest of the year, just read a little differently depending on the season and whatever the wind did the night before.

Quick Answers

Frequently asked

When is sea turtle nesting season on Florida's Gulf coast?

May through October. Nesting peaks in mid-summer, and hatching overlaps the back half of the season, so from late summer into fall you can find both fresh nests and hatchling tracks.

What does a sea turtle crawl look like?

A wide, symmetrical drag mark in the sand, like tractor treads, running from the surf up to the nest and back. It's the track a nesting female leaves coming ashore at night.

Will I see a turtle nesting on a daytime tour?

No. Turtles nest at night, so on a daytime tour you'll see their evidence instead: crawls in the sand and roped, staked nests near the high-tide line.

Why are beach lights a problem during nesting season?

Artificial light disorients both nesting females and hatchlings, drawing them away from the Gulf and toward danger. Keeping lights out at night gives turtles the dark beach they need.

Where can I see nesting evidence near Marco Island?

On the dark, undeveloped boat-only barrier beaches such as Keewaydin, Kice and Cape Romano, where most local nesting happens. Crawls and roped nests are visible there through the season.

What should I do before leaving a nesting beach?

Fill in any holes you dug and flatten sandcastles, since hatchlings can get trapped or blocked by them. Always stay back from roped nests and crawls.
