Sea turtles are an iconic part of Myrtle Beach’s coastal ecosystem. Their annual return for nesting and the emergence of hatchlings represent a natural cycle. This event highlights the balance of coastal life and enriches the area’s biodiversity.
Nesting and Hatching Season
In Myrtle Beach, the sea turtle nesting season typically spans from May 1st to October 31st. During this period, female sea turtles, predominantly loggerheads, emerge from the ocean to lay their eggs in nests dug into the sand dunes. While loggerheads are the most common species nesting in the area, green, Kemp’s Ridley, and leatherback sea turtles are also occasionally observed.
Hatching generally begins approximately 60 days after the eggs are laid. This means the hatching season in Myrtle Beach typically runs from late July through October, with peak activity often observed in August and September. Environmental factors, such as sand temperature, can influence the exact incubation period, with warmer temperatures potentially leading to slightly shorter incubation times. These temperature variations within the nest can also determine the sex of the hatchlings, with warmer sand producing more females and cooler sand producing more males.
The Hatching Event
Once eggs incubate, hatchlings begin to emerge. This process often starts with them collectively digging their way up through the sand, a phenomenon sometimes called a “boil” due to the sand churning as they emerge. This mass emergence helps them overwhelm predators.
Hatchlings usually emerge at night, which helps them avoid predators and the heat of the day. Upon surfacing, they instinctively orient themselves toward the brightest horizon, which on a natural beach is the reflection of the moon and stars on the ocean. They then embark on a swift, instinct-driven journey down the beach to the sea. This initial journey is a stage in their life cycle, as they face obstacles and predators.
Safeguarding Nests and Hatchlings
Protecting sea turtle nests and hatchlings is a collaborative effort involving local conservation groups and state agencies. The South Carolina Department of Natural Resources (SCDNR) Marine Turtle Conservation Program plays a significant role in managing and protecting sea turtles across the state. Local organizations, such as the North Myrtle Beach Sea Turtle Patrol and South Carolina United Turtle Enthusiasts (SCUTE), work closely with the SCDNR to monitor nesting sites and ensure the safety of these creatures.
Public cooperation is important for conservation success. Avoid disturbing marked nesting areas, which are often roped off or signed. Beachfront lighting poses a significant threat to hatchlings, as artificial lights can disorient them, drawing them away from the ocean. Turning off or shielding outdoor lights visible from the beach, especially from dusk until dawn during nesting season, is a protective measure. Removing beach chairs, toys, and filling in holes at the end of the day helps prevent obstacles for nesting females and emerging hatchlings.
Ethical Observation Guidelines
Observing sea turtle activities in Myrtle Beach requires adherence to ethical guidelines to ensure their well-being. Maintain a respectful distance from nesting females and hatchlings to avoid disturbing them. Approaching too closely or making noise can cause nesting turtles to abandon their efforts.
Using white lights or flash photography at night is prohibited, as these can disorient both nesting turtles and hatchlings. If observing after dark, only use specialized red or amber lights, which are less disruptive. If encountering a distressed, injured, or disoriented sea turtle or hatchling, contact local wildlife authorities, such as the North Myrtle Beach Sea Turtle Patrol at 843-213-9074 or the SCDNR hotline at 1-800-922-5431. Do not attempt to intervene directly, as handling or interfering with hatchlings can prevent them from properly orienting themselves.
