Sea Turtle Nesting Season: What, When, and How

The sea turtle nesting season has begun! Get ready to witness one of nature’s most wild and thrilling spectacles!

Imagine this: A warm night. The sound of the sea gently lapping at the shore. Everything is calm. Suddenly, something breaks the silence. A silhouette emerges from the waves, slow and powerful. You’re not watching a movie. This is real. And the best part… it’s happening right now.

It’s sea turtle nesting season, that special time of year when beaches transform into the stage for one of the most beautiful and heartwarming spectacles you can imagine. Thousands of turtles arrive from the deep, following an instinct that has been etched in their DNA for centuries. And you… can witness it.

But be careful—this isn’t for everyone. This is not your typical “Instagram photo tour.” No. Here, you’ll see real life in action. Natural cycles that few have the privilege to witness. And if you’re lucky… you might just see something you’ll never forget.

Loggerhead turtles meticulously digging their nests, or tiny green sea turtles desperately racing to save the life they’ve just begun—this is a critical moment, not only for them but for an entire ecosystem that depends on their survival.

Want to know when? Where? What you need to do to experience it? Well, I’ll tell you in a minute. But first, let me warn you: this article is not for the usual curious onlookers. Here, you’ll learn, yes, but you’ll also feel.

Because the sea turtle nesting season isn’t just an event. It’s nature’s secret. And today, you have the chance to discover it.

But fair warning… once you finish reading, you’ll never look at the sea in the same way again.

1. Sea Turtle Nesting Season: Dates and Locations

This is where things get exciting. Talking about the sea turtle nesting season means diving into a secret world, one that happens when almost no one is watching. For months, the beaches you know transform. They become a wild stage where life and survival play out daily.

Depending on the species and the location, the nesting season follows the rhythm of an invisible clock, perfectly synchronized. The nesting season usually lasts from March to November along the Atlantic coast, although most take place between May and October.

For example, Florida is home to 90% of sea turtle nesting in the United States. And the Gulf of Mexico, another globally important turtle nesting site, where loggerhead turtles reign. They arrive from May to August, and the hatchlings make their run to the ocean between July and October. It’s a fascinating cycle: eggs beneath the sand, silent incubation, and then an explosion of life racing toward the sea. It all happens like an ancient ritual, season after season.

Green turtles also have their moment. Less frequent, but equally impressive, they nest from March to November. And if you’re lucky, you might see one of the giant leatherback turtles or the rare Kemp’s ridley turtles.

3. Marine Turtle Species and Their Nesting Habits

Let’s explore sea turtle nesting habits, focusing on the intriguing loggerhead, hawksbill, and green turtles.

Loggerhead Turtle: Smarter Than You Think Under the silver glow of the moon in Puerto Aventuras, a female loggerhead turtle drags her body across the sand, leaving a trail of zigzag grooves behind her. This isn’t just a stroll; it’s a mission.
After finding the perfect spot, she begins digging a nest with her powerful flippers. In her heart, she knows she’s creating a safe haven for her future offspring. She lays between 65 and 180 eggs in a single clutch, then covers them with sand before slipping back into the ocean, leaving them to incubate in the warmth of the earth. Loggerhead nests are true hidden treasures! During a sea turtle nesting season females can lay between 3 and 7 clutches, with about 10 to 15 days between each.
After 60 exciting days, the hatchlings emerge. They wait for darkness to make a dash for the shining waves, dodging hungry predators lurking in the shadows. It’s a perilous race, and only a few will survive to adulthood.

Green Turtle: The Gentle Herbivore Can you imagine it? A female green turtle returns to nest on the very same beach where she was born. This remarkable journey, called natal homing, is repeated every two to three years. After traveling vast distances, she’s back home, ready to fulfill her destiny.
With the sun setting, she makes her way across the soft sand, her flippers ready to dig. Each movement carves out a space for her clutch. Depending on her mood, she may lay between 75 and 200 eggs at once, returning to the ocean after covering her nest. Nesting at night isn’t just a whim; it’s a smart survival tactic, minimizing the risks of overheating and predator attacks.
Every few years, she repeats this cycle, averaging about 3.6 clutches. Imagine the excitement in the air when the hatchlings emerge 60 days later, racing for the same precious prize: the sea!

Hawksbill Turtle: Nesting Without Losing Elegance Every hawksbill turtle nesting season arrives with its colorful shell and graceful presence. No wonder it’s one of the most prized treasures of our oceans.
Hawksbill turtles also undertake epic journeys, but their nesting season remains a mystery. Depending on the coast, they may nest between April and October, seeking out secluded beaches to lay their eggs. During this time, females emerge from the water, and you can feel the tension in the air. Will they manage to create a safe nest?
When they reach the shore, they engage in an ancient ritual. Using their flippers, they dig a hole in the sand where they deposit between 140 and 200 eggs. They do this with surprising delicacy, covering the nest with sand when finished—a true act of love and hope. Afterward, they return to the ocean, leaving nature to work its magic.
After about 60 days, the tiny hatchlings emerge from the nest, ready to face the vast ocean. But here’s the unsettling fact: only one in a thousand will make it to adulthood. Life is tough, and every nest is a battlefield.

Climate Plays a Crucial Role
Like their cousins, hawksbill turtles rely on temperature to determine the sex of their offspring. When the sand warms to around 29°C, life begins to flourish! But be careful—if it gets too hot, most of the eggs will hatch as females. And if the temperature drops, males are more likely to emerge. Nature has its own logic.

4. What Does a Sea Turtle Nest Look Like?

Imagine the salty breeze brushing your face as you stroll along the beach. Suddenly, you come across a small bump in the sand. What could it be? It might be a sea turtle nest, and it’s crucial to recognize it to help protect these vulnerable species.

Identifying a Sea Turtle Nest

You’re walking along the beach at sunset, the sand still warm beneath your feet. Suddenly, you stop. Is that… a turtle nest?

At first, you might not notice it, but once you know what to look for, it’s like discovering a hidden treasure.

Physical Appearance

A sea turtle nest looks like a small mound of sand, similar to a poorly made sandcastle. After a female turtle’s visit, a slight depression or bump remains on the surface. These nests are often easy to overlook, especially if they blend in with the surrounding sand.

Signs to Watch For

1. Tracks in the Sand: The most obvious clue is the trail of tracks left by the turtle as she emerges from and returns to the ocean. These tracks resemble large marks and are the first sign that a nest has been made.
2. Nest Location: Always look above the high tide line on sandy beaches. Turtles prefer to nest in open areas with minimal vegetation.
3. Appearance of the Eggs: Freshly laid eggs are usually white and round, about the size of golf balls.
4. Post-Hatching Signs: After the hatchlings emerge, the nest may show signs of activity, such as small holes where the newborn turtles crawled out. The broken eggshells typically remain inside the sand. A successful nest won’t have scattered eggshells, indicating that the hatchlings have made their way to the ocean without leaving traces.

5. The Importance of Protecting Turtle Nests

Protecting the nests is vital for the survival of sea turtles. Why? Here are a few key reasons:

Egg Vulnerability: The eggs are a delicacy for predators such as raccoons, birds, and crabs. Additionally, human activities like beach development and pollution threaten their safety.

Survival of Hatchlings: The journey from the nest to the ocean is perilous. Hatchlings face predators, artificial lights that disorient them, and obstacles on the beach. Protecting the nests significantly increases their chances of reaching the water.

• What to do if you see a sea turtle nest with eggs?
  Don’t even think about touching it! What you have in front of you is a nest during the sea turtle nesting season—a natural incubator protected by state and federal laws. What’s the best thing you can do? Observe from a safe distance without touching, and if you need more information, call the nearest conservation center. They will know what to do. You just watch the scene.
• What to do if you see a sea turtle laying eggs?
  Look. Feel the excitement in the air. But please, don’t get too close. The last thing we want is to scare the future mama. Stay calm and keep quiet. No lights. No loud noises. Sea turtle nesting is a fragile, delicate process—a ritual that has been repeated for millions of years—and your presence should be invisible. She knows what she’s doing and needs tranquility. It’s her moment, and your role here is to be just a respectful observer.
• What if I find a hatchling struggling to get out of the nest?
  This is where nature takes charge. It may be tempting to help, I know. But resisting that temptation is crucial. Even if it seems like it needs help, it is illegal to intervene. The little ones must make the journey from their nest to the ocean on their own. It’s part of their natural process, and every effort counts. If you intervene, you could do more harm than good. The struggle makes them strong. It’s part of the survival journey.
• Who should I contact if I see an injured or stranded sea turtle?
  If you see a turtle or hatchling that appears injured or in trouble in Mexico, you can contact the Ministry of Environment and Natural Resources (SEMARNAT) or local wildlife rescue organizations operating in the area. They can provide guidance and assistance for stranded or injured sea turtles.
• Can I take photos with a red flashlight while turtles are nesting at night?
  While it may seem like a great idea, photographing turtles during the sea turtle nesting season at night is prohibited without permission. Flashlights, even red ones, can disturb them. If you really want to capture the moment, do it with your memories, not with a camera. This way, you’ll be protecting these creatures during their delicate nesting process.
