Ombai Strait (, , ) is an international strait in Southeast Asia. It separates the Alor Archipelago from the islands of Wetar, Atauro, and Timor in the Lesser Sunda Islands. The strait is also the western portion of a pair of international straits, the other one being Wetar Strait; the two straits combine to link the Pacific Ocean with the Indian Ocean. Etymology Ombai is an alternative name for the island of Alor, in the Alor Archipelago on the other side of the strait's north, north western and western coastline. In Tetum, the expression tasi feto () is often used to refer to the 'Ombai-Wetar Strait', which extends along most of Timor's northern shores. The counterpart of that body of water, the Timor Sea, which has larger waves, is more turbid, and washes the whole of Timor's southern coastline, is commonly referred to in Tetum as tasi mane (). Geography Ombai Strait is relatively narrow and deep (). It has complex and extreme bathymetry, ranging from narrow reef flats (often less than wide) partly covered with seagrass and coral, to depths within of the coast. The strait separates the Alor Archipelago from the islands of Wetar, Atauro, and Timor in the Lesser Sunda Islands. It also straddles the boundary between the Banda Sea (in its north east) and the Savu Sea (in its south west). The Alor Archipelago, and the western part of Timor except the coastal exclave of Oecusse, which is on the north coast of western Timor, are part of the province of East Nusa Tenggara, Indonesia. Wetar is part of the Maluku Province of Indonesia. Atauro, Oecusse, and the eastern part of Timor comprise the nation of East Timor. The southern limit of the Banda Sea runs along the southern edge of the strait from the eastern extremity of Timor along its north coast as far south west as longitude 125° East. From that point, the Banda Sea's western limit heads north to Alor Island, where it starts a further run, east, along Alor's south coast, around its east point, and beyond. Meanwhile, Ombai Strait continues to run from longitude 125° East in a south westerly direction, now within the limits of the Savu Sea. It extends, as part of that sea, at least as far south west as Batek Island, at the north western tip of Oecusse. From Ombai Strait's south western, Savu Sea, end, the
