Diving in Mozambique

Mozambique has a long coastline spread out over the tropical east coat of Africa south of the equator, with several islands on the continental shelf. Reef-building corals live where there is suitable substrate and good light – generally where there is no major river mouth nearby. The current generally flows north to south, and can be strong. This carries turbid water away, and makes drift diving necessary in many places.

Mozambique has a tropical climate with two seasons, a wet season from October to March and a dry season from April to September. Rainfall is heavy along the coast and decreases in the north and south. Cyclones are common during the wet season.

The sea temperature is tropical. Water temperatures range from 29˚C in summer to 22˚C in winter, and will seldom be below 24˚C. The diving season is year round. People from cooler climates may find winter more comfortable, and there are fewer mosquitos as this is the dry season.

Visibility can range from 8–40 m, depending on the amount of plankton in the water.

The marine ecology of Mozambique is classified as Tropical Indo-Pacific, which is the most diverse marine ecology known. Obviously not all species from this bioregion will be found in all parts of it, but this is an indication of the diversity which can be expected here. A wide range of reef building corals, and also other coral types can be found here, along with a diverse invertebrate fauna sharing the shelter and habitat provided by the corals. Fish are also represented by a large diversity of species, many of which are particularly colourful.

Humpback whales can be spotted during their migration from June until November.

Whale sharks are present all year round and in abundance between November and March. These gentle giants can reach up to 12m in length and weigh up to 20tonnes.

Southern Mozambique includes the Municipios of Maputo, Gaza, Inhambane and Sofala from the southern border with South Africa at Ponta d'Ouro north to the Zambesi river.
