Sea Turtle Species & Best Months in Cozumel
| Species | January–March | April–June | July–September | October–December | Likelihood |
|---|---|---|---|---|---|
| Green Sea Turtle | Common | Common | Common | Common | On the reef |
| Hawksbill Turtle | Regular | Regular | Regular | Regular | On the reef |
Cozumel's reefs hold both green and hawksbill turtles. Greens graze the seagrass and reef flats, while hawksbills pick at sponges along the coral walls of Palancar and Columbia. They share the water with rays, groupers and the odd nurse shark. All sea turtles are protected in Mexico, so keep your distance and never touch or chase them.
What to Expect on the Day
1
Board the boat
Set off from Cozumel or cross from Playa del Carmen, cruising over clear water to the reefs on the island's protected west side.
Bring reef-safe sunscreen; Cozumel's reefs are a national marine park.2
Snorkel the turtle bay
Slip in over a shallow bay and sandy flats where green turtles graze and stingrays glide the bottom.
3
Snorkel Palancar or the reef
Move on to the coral of Palancar or a nearby reef, where hawksbills patrol the wall among sponges and fish.
4
Float the El Cielo starfish sandbar
Finish over El Cielo, a shallow sandbar dotted with giant starfish, with drinks and ceviche on board.
No turtle sighted? Turtles are a regular sight on Cozumel's reefs and in the turtle bay, but this is reef snorkeling rather than a dedicated turtle swim, so sightings vary by day. For turtles feeding in the shallows every day, book a beach turtle swim in <a href="/swim-with-turtles-akumal/">Akumal</a>.
Sea Turtle Behaviors to Watch For
Cruising the Reef Wall
Hawksbills work their way along the Palancar and Columbia coral walls, picking at sponges. A slow, steady swimmer is easy to watch from a few metres back.
On the reef
Grazing the Shallows
Green turtles crop seagrass and algae on the sandy flats and in the turtle bay, where the water is shallow and calm.
Turtle bay stop
Surfacing to Breathe
Turtles rise for air every few minutes to about an hour. Give them a clear route to the surface and never block it.
