Bazaruto is a sandy island located approximately 50 miles southeast of the mouth of the Save River, Mozambique. The warm, southward-flowing Mozambique current seems to contribute to the increasing buildup of the sandy coastline. Because the water along this coastal area is very clear, much of the sub-surface channel pattern around the island is discernible. Several narrow lines of plankton bloom parallel the shoreline. The coastal plains show numerous lakes and a swampy environment that appears to be karst topography. Underlying the area is limestone rock that has eroded into a pockmarked landscape, creating water-filled sinkholes. Rainfall in this humid subtropical climate amounts to between 20 and 40 inches annually.
Thick forests of casuarinas, coconut palms and cashew nut trees grow on the shores of the island. The island is the largest in the Bazaruto Archipelago, with towering dunes and large inland lakes frequented by many water birds and even crocodiles.
Fishermen the world over know Bazaruto to be one of the best spots for catching marlin, kingfish and other large game fish. The island is particularly good for surf fishing, and there are rubber ducks to take divers to various reefs along the coast.
Bazaruto Island has a hundred-year-old lighthouse on the northern point, which serves as a signal to the many ships which pass by the channel up the east coast of Africa.
During the Second World War, Japanese submarines waited here for Allied ships carrying troops and provisions to the battlegrounds in the north. One got lucky in June 1942, torpedoing a Yugoslav freighter “Supetar” and sinking her close to the north point of the island.
