When to Go

You can dive Cocos year-round but May through October is usually considered the best time. This is the rainy season and there are frequent showers. In the summer months, water temperatures are about 79f (26c) and a 3mm wetsuit will usually be sufficient. The water temperatures are around 75f (24c) during the winter. Most operators recommend a 5mm wetsuit with hood during the winter months because of common thermoclines.

What You Can See

The summer months of June, July, and August are also the best months to see huge schools of migrating Scalloped Hammerhead Sharks that Cocos is famous for. There is an absolute abundance of marine life here including Spotted Eagle Rays (sometimes in schools), multiple species of Sharks (Silky Sharks, Whitetip Reef Sharks, Tiger Sharks, and more), Turtles (Green, Hawksbill, and Ridley), Manta Rays, Marble Rays, Stingrays, Frogfish, Killer Whales, Dolphins, large schools of Jacks, Octopus, and much more.
