Off the coast of East Africa, diving in Madagascar reveals one of the Indian Ocean’s most biodiverse marine environments. The island is bordered by extensive coral reefs, offshore banks, and remote drop-offs that support an impressive range of marine life. Divers encounter turtles, reef sharks, manta rays, whale sharks, and vibrant schools of tropical fish, while macro enthusiasts enjoy nudibranchs, shrimp, and rare critters. With relatively low diver traffic and pristine conditions, Madagascar scuba diving offers a true sense of exploration.
Seasonal shifts play a key role in the best time to dive in Madagascar. Prime diving conditions typically occur from April to December, when seas are calmer and visibility is high. Water temperatures range from 24–28°C (75–82°F). The austral summer from January to March brings warmer water but also higher rainfall and cyclone risk. From July to October, divers may encounter migrating humpback whales, adding a unique highlight to Indian Ocean diving.
