Hundreds of crystal clear cenotes (caves) can be found throughout Mexico. Cenote Dos Ojos near Tulum is the most famous and is easily accessible to most divers.
The MUSA, located next to Cancun, is an underwater contemporary museum of art consisting of over 500 permanent life-size sculptures from English artist Jason deCaires Taylor.
Isla Mujeres, just off-shore from Cancun, sits at the join of the Gulf of Mexico and the Caribbean. As such, it attracts hundreds of Whale Sharks from June to September each year.
There is no bad time to dive the Caribbean. In fact, the water temperatures remain constant year-round and cool only slightly during the winter months, meaning it’s possible to dive approximately 300 days each year.
December to April is considered the best time to visit Mexico and therefore is the most popular time to dive in the Caribbean. Because the winter months constitute high season, you should make sure to book as early as possible in order to secure the best rate.
On average, water temperatures vary between 78 and 82ºF (25 and 28ºC) in Cancún.
The best time for cenote diving is between May and September. These months bring the best light to the caves and result in the better photographs.
Also note that diving in the Caribbean is possible year-round. Simply keep an eye on the forecast during the summer and early fall. These seasons do see the occasional hurricane. When there isn’t a hurricane, the weather during the summer is hot and humid with the occasional rain shower.
June to September in particular is best for whale sharks near Isla Mujeres.
As an added bonus, the summer months are low season throughout Mexico. At this time, you’ll find the best deals on diving and accommodation. If you enjoy uncrowded, Caribbean dive sites, travel to Mexico between May and September.
Dolphins patrol deeper waters, while stunning colorful fish hang out by the reefs. You will see eels and lobsters near overhangs, as well as plenty of eagle rays gliding through the shallows. If you dive through a few of the tunnels, you’re sure to see nurse sharks sleeping in the dark.
A major attraction in the Cancún area are the whale sharks that visit Isla Mujeres from June to September, and a little further south, you’ll find bull sharks in Playa del Carmen from November until March. There’s also a chance of spotting Green Turtles, Loggerhead Turtles and sailfish during their respective migrations.
