Tarawa is an atoll and the capital of the Republic of Kiribati, in the Micronesia region of the central Pacific Ocean. It comprises North Tarawa, which has 6,629 inhabitants and much in common with other more remote islands of the Gilberts group, and South Tarawa, which has 56,388 inhabitants , half of the country's total population. The atoll was the site of the Battle of Tarawa during World War II. Etymology Tarawa is an old Gilbertese form for Te Rawa, meaning "The Passage" (of the Lagoon), named for the unusual large ship channel to the lagoon. In the popular etymology based on Kiribati mythology, Nareau, the God-spider, distinguished Karawa, the sky, from Marawa, the Sea, from Tarawa, the land. Geography Tarawa has a large lagoon, in total area, and a wide reef. The lagoon is widely open to the ocean, with a large ship pass. Although naturally abundant in fish and shellfish of all kinds, marine resources are being strained by the large and growing population. Drought is frequent, but in normal years rainfall is sufficient to maintain breadfruit, papaya and banana trees as well as coconut and pandanus. North Tarawa consists of a string of islets from Buariki in the north to Buota in the south. The islets are separated in places by wide channels that are best crossed at low tide, and there is a ferry service between Buota and Abatao. Only Buota is connected by road to South Tarawa, via a bridge. On South Tarawa, the construction of causeways has now created a single strip of land from Betio in the west to Tanaea in the northeast. Climate Tarawa features a tropical rainforest climate under the Köppen climate classification. The climate is pleasant from April to October, with predominant northeastern winds and stable temperatures close to . From November to March, western gales bring rain and occasional cyclones. Precipitation varies significantly between islands. For example, the annual average is 3,000 mm (120 in) in the north and 500 mm (20 in) in the south of the Gilbert Islands. Most of these islands are in the dry belt of the equatorial oceanic climatic zone and experience prolonged droughts. Administration Tarawa atoll has three administrative subdivisions: Betio Town Council (or BTC), on Betio Islet; (or TUC), from Bairiki to Tanaea; and Eutan Tarawa Council (or ETC), for North Tarawa or Tarawa Ieta, consisting of all the islets on the
