On average, the island stays around a blissful 80 degrees. The summers are slightly warmer, ranging in the mid 80s to 90s and the winters cool to the mid 70s. It's always a beach day in Cozumel, as the water ranges from a warm 77 to 82 degrees throughout the year.
Cozumel is home to the largest reef system in the Americas, the Mesoamerican Reef. Teeming with hundreds of tropical fish, turtles and other vibrant sea life, it is truly a diver's dream. But even if you don't explore down into the depths of the ocean, there is much to see for snorkelers too. There are as many as 250 different species of tropical fish including the queen angelfish and the illusive toadfish, seen nowhere else in the world.
Above the sparkling surface of the water, the trees are speckled with frigate birds, brown pelicans, olivaceous cormorants and others. If you look closely, you may catch a glimpse of a tree frog, a crocodile or the prehistoric iguana resting in the lush vegetation. But no worries, our locals are the friendliest in the world
