What’s Special About Cozumel? 

Cozumel is located on the expansive Mesoamerican Barrier Reef, which is the second largest barrier reef in the world, only second in size to the Great Barrier Reef. There’s an explosive array of multi-colored coral formations and an abundance of wildlife, like turtles, stingrays, and sharks, and the drift diving here is possibly the best in the world. Additionally, the warm waters are so clear that you can often have over 100 feet (30m) of visibility!


Must-See Dive Sites 

There are somewhere between 20 and 30 dive sites around Cozumel, depending on who you ask. Most of them are suitable to divers of all levels who are comfortable with drift diving; however, some of the dive sites on the east and south side of the island can be prone to heavy currents and are therefore more suitable to experienced divers.

When to Visit Cozumel for Diving

If you’ve already done some research on Cozumel diving, you already know that there’s no bad time to dive there. For one, water temperatures don’t fluctuate very much. Moreover, there are decent diving conditions on roughly 300 days out of the year.

That said, each season has its own perks and downsides. December to April is Cozumel’s dry season, and the weather is clear and warm, while the water may be a bit more chilly. However, this is also peak season for tourism, so places (dive sites included!) will be more crowded. Meanwhile, May to October is the wet season, and hurricanes are always a risk at this time of year. However, the summer months are generally uncrowded, and the waters are slightly warmer.

If you want to take a break from diving, Cozumel and the Yucatán Peninsula also has a rich history to explore. Mayan civilization in the area dates back thousands of years. After the Spanish colonizers arrived, this civilization declined rapidly. However, archaeological sites around the island and further afield near Tulum, Cancún and Playa del Carmen still reveal the fascinating traces of pre-colonial life.

Diving in Cozumel is an unparalleled adventure for divers of all skill sets, and Cozumel is an unforgettable island both above and under the water. If you haven’t already booked a trip, don’t miss out!
