Geography of Saint Helena
Saint Helena is an island in the South Atlantic Ocean, about midway between South America and Africa, at the geographic coordinates 15°56′S 5°42′W / 15.933°S 5.700°W. St Helena has a land area of 122 square kilometres and is part of a wider territory called Saint Helena, Ascension and Tristan da Cunha which includes Ascension Island and the island group of Tristan da Cunha.
The climate of Saint Helena island can be described as tropical, marine and mild, tempered by the Benguela Current and trade winds which blow almost continuously. Similarly, the climate of Tristan da Cunha is marine, mild and also tempered by trade winds, although the climate is temperate in nature. Ascension Island is warmer and wetter than St Helena.
Saint Helena has a rugged, volcanic terrain, with small scattered plateaus and plains, with the largest area of level ground on the island being Prosperous Bay Plain in the eastern arid area. The other islands of the group have a volcanic origin. The highest point on the island is Diana's Peak at 818 metres (2,684 ft), though Queen Mary's Peak on Tristan da Cunha is the highest in the British territory at 2,062 m.
