Situated just east of the Caribbean Sea, is an independent island nation in the western Atlantic Ocean. At roughly 13° North and 59° West, Barbados lies in the southern Caribbean region, where it is a part of the Lesser Antilles island-chain. Its closest island neighbours are St. Vincent and St. Lucia to the west, Grenada to the south-west, and Trinidad and Tobago to the south, with which Barbados now shares a fixed official maritime boundary.
Barbados' total land area is about 430 square kilometres, (166 square miles), and is primarily low-lying, with some higher regions in the island's interior. The organic composition of Barbados is thought to be of non-volcanic origin and is predominantly composed of limestone-coral. The island's climate is tropical, with constant trade winds off the Atlantic Ocean serving to keep temperatures mild.
