Cozumel was a well-known diving spot before Cancún ever existed, and it has ranked for years among the top five dive destinations in the world. Tall reefs line the southwest coast, creating towering walls that offer divers a fairy-tale landscape to explore. For nondivers, it has the beautiful water of the Caribbean with all the accompanying watersports and seaside activities. What's more, Cozumel has the feel of a small island--short roads that don't go very far, lots of mopeds, few buses and trucks, and a sense of isolation. The island is 45km (28 miles) long and 18km (11 miles) wide, and is 19km (12 miles) from the mainland. Most of the terrain is flat, undisturbed scrubland. The name comes from the Maya word Cuzamil, meaning "land of the swallows." Today, it remains the home of two species of birds found nowhere else: the Cozumel vireo and the Cozumel thrasher.
The best time to visit Cozumel is from May to July. The island enjoys daytime temperatures around 80 degrees Fahrenheit and nighttime temperatures in the 70s. Winter temperatures range between the upper 60s and the lower 80s, so we recommend packing layers. The summer months into early fall are the rainy season, and hurricanes have been known to wreak havoc on the island.
