Mayotte

Mayotte is situated in the Comoros archipelago, in the Mozambique Channel, and has one of the biggest lagoons in the world (425mi²/1100km²), surrounded by a barrier reef over 100 miles (160km) long. Its warm waters, protected by ocean currents, are home to very varied underwater sea life: turtles, dolphins, whales (from July to October), a plethora of fish (over 800 species) and coral (300 species), as well as the extremely rare dugong (less than twenty recorded individual animals).

The island has a wide variety of snorkeling spots. Although you will probably start by exploring the seagrass and reef drop-offs that are easily accessible from the beaches (the most famous of which is N’Gouja, an excellent place to observe green turtles), you shouldn’t leave without taking an excursion by boat, which is the only way to reach the islets and reefs dispersed throughout the lagoon (Îlots Choizil, Ilot de Sable Blanc du Nord, etc.) or the immense barrier reef (lying several miles from the coast), interspersed with channels.

When to go to Mayotte?

With an average temperature of 75°F (24°C) in the lagoon, snorkeling is possible in Mayotte all the year round. From October to March, during the southern summer, temperatures are high (85-90°F/29-33°C on average) and rains abundant (with a peak in January-February). After heavy rain, the coastal waters are charged with sediment, making visibility poorer. From April to September, temperatures are cooler (74-79°F/23-26°C) and the waters are generally clear, but wind is more common.
