Baby Sea Turtle Hatching in Cozumel
Every year from May through November, two species of endangered sea turtles return to Cozumel's beaches to lay their eggs. Witnessing baby turtles hatch and make their first journey to the Caribbean Sea is one of the most unforgettable experiences the island has to offer.
The Cozumel Turtle Salvation Program works tirelessly to protect every nest and give every hatchling the best chance at survival.
Two Species Call Cozumel Home
Cozumel's protected east side beaches provide critical nesting habitat for two species of endangered sea turtles. Both are protected under Mexican federal law and international conservation agreements.
Green Sea Turtles
Chelonia mydas
Green turtles are the most commonly seen species nesting on Cozumel's beaches. Named for the green color of their body fat (not their shell), these gentle giants can weigh up to 400 pounds. They are herbivores, feeding primarily on seagrass and algae found in Cozumel's shallow coastal waters. Green turtles return to the same beach where they were born to lay their own eggs — a remarkable act of navigation across thousands of miles of open ocean.
Loggerhead Sea Turtles
Caretta caretta
Loggerhead turtles have the longest nesting season on Cozumel, extending from May through November. They are named for their large, powerful heads and strong jaws, which they use to crush hard-shelled prey like conchs, crabs, and sea urchins. Loggerheads are slightly smaller than Green turtles but are equally important to Cozumel's marine ecosystem. Their nesting activity on the east side beaches is carefully monitored by conservation teams.
Month-by-Month Timeline
Sea turtle nesting season in Cozumel runs from June through November, with hatching typically occurring 45 to 65 days after eggs are laid.
Early nesters arrive. Green turtles begin coming ashore on the east side beaches.
Peak arrival. Both Green and Loggerhead turtles are actively nesting. Beach patrols increase.
Heavy nesting continues. First nests from May begin approaching hatch time.
First hatchlings emerge. Nightly releases begin at protected hatcheries.
Peak hatching season. Hundreds of baby turtles make their journey to the sea.
Green turtle nesting winds down. Loggerheads continue. Late-season hatching ongoing.
Final Loggerhead nests hatch. Conservation teams complete data collection for the year.
Turtle Conservation Zone
The Turtle Conservation Zone is located on the east side of Cozumel — the wild, undeveloped coastline that faces the open Caribbean. This stretch of beach is where the majority of nesting activity occurs, precisely because it remains relatively free from human development and artificial lighting.
The east side is also one of the most beautiful and dramatic parts of the island, with rugged limestone cliffs, secluded sandy coves, and powerful surf. Several of our tours pass through this area, giving visitors the chance to see the nesting beaches firsthand.
- Protected under Mexican federal environmental law
- Monitored nightly during nesting season by trained volunteers
- Artificial lighting restrictions enforced near nesting beaches
- Accessible via our Jeep Tour and East Side excursions
- Biodegradable sunscreen required in conservation areas

Cozumel Turtle Salvation Program
The Cozumel Turtle Salvation Program is a dedicated conservation effort that protects sea turtle nesting sites, monitors nests, rescues eggs from vulnerable locations, and releases hatchlings safely into the ocean. The program operates entirely during nesting season and relies on a combination of trained biologists, local volunteers, and community support.
Beach Patrols
Trained volunteers and biologists patrol the east side beaches every night during nesting season, locating and marking new nests to protect them from predators, vehicle traffic, and human disturbance.
Nest Protection
When nests are found in vulnerable locations — too close to the waterline, in areas with heavy foot traffic, or near artificial lighting — eggs are carefully relocated to protected hatcheries where they can incubate safely.
Hatchling Releases
When the eggs hatch (typically 45 to 65 days after being laid), conservation teams carefully guide the baby turtles to the ocean at night, ensuring they make it safely past predators and obstacles.
Community Education
The program runs educational workshops for local residents, hotel staff, tour operators, and visitors. Understanding why sea turtles matter — and what threatens them — is the foundation of lasting conservation.
Habitat Restoration
Efforts include removing debris from nesting beaches, reducing artificial light pollution near nesting areas, and working with beachfront properties to create turtle-friendly lighting that does not disorient nesting females or hatchlings.
Research & Monitoring
Every nest is documented. Data on nest location, clutch size, incubation period, and hatch success rate is collected and shared with international sea turtle research organizations to support global conservation efforts.
How Visitors Can Help
You do not have to be a marine biologist to make a difference. Every visitor to Cozumel can contribute to sea turtle conservation in meaningful ways.
Donate to Conservation Programs
Financial contributions support beach patrols, hatchery maintenance, volunteer coordination, and scientific research. Even small donations make a meaningful difference for a program that operates on limited resources.
Volunteer During Nesting Season
Visitors who are staying on the island for an extended period can volunteer with the conservation program. Tasks include night beach patrols, nest monitoring, hatchling releases, and data collection.
Respect Nesting Areas
Stay behind marked barriers around turtle nests. Never touch, approach, or shine lights on a nesting turtle. Keep the beach clean — trash and debris can trap or injure nesting mothers and hatchlings.
Report Sightings
If you see a sea turtle on the beach — nesting, injured, or stranded — report it immediately to the conservation program or local authorities. Do not attempt to move the turtle yourself.
Use Reef-Safe Sunscreen
Chemical sunscreens containing oxybenzone and octinoxate are harmful to sea turtles and the marine ecosystem. Use biodegradable, reef-safe sunscreen whenever you are near the ocean or nesting beaches.
Turn Off Beach Lights at Night
Artificial light disorients nesting females and confuses hatchlings, drawing them away from the ocean and toward danger. If you are staying near a nesting beach, turn off exterior lights after dark during nesting season.
Biodegradable & Reef-Safe Sunscreen Required
Cozumel has strict environmental regulations to protect its marine ecosystems. Conventional sunscreens containing oxybenzone, octinoxate, and other harmful chemicals are prohibited in marine parks, snorkeling areas, and near turtle nesting beaches. These chemicals damage coral reefs, poison marine life, and can harm sea turtle eggs and hatchlings.
Please bring biodegradable, reef-safe sunscreen with you, or purchase it locally before entering any natural area. Look for products labeled “reef safe” or “biodegradable” and check that the ingredients list does not include oxybenzone or octinoxate.
