Saint Lucia is a tropical island country in the eastern Caribbean Sea. It is a part of the Lesser Antilles and it is north of the islands of Saint Vincent and the Grenadines and south of Martinique. Is 27 miles (43 km) long and has a maximum width of 14 miles (23 km). The capital and major port is Castries. Saint Lucia is a member of the Commonwealth.
The island is of volcanic origin and is bisected from north to south by a central ridge of wooded mountains, the highest point being Mount Gimie (3,145 feet [959 metres]). Many streams flow from the mountains through fertile valleys. In the southwest are the Gros and Petit Pitons (2,619 feet [798 metres] and 2,460 feet [750 metres], respectively), two immense pyramids of rock rising sharply from the sea and enclosing a small bay. Near Petit Piton, in the crater of an ancient volcano, are the boiling sulphur springs from which the nearby town of Soufrière takes its name. A choice tourist site, the springs also contain substantial energy potential.
Saint Lucia lies in the path of the northeastern trade winds and has a tropical maritime climate. Rainfall and temperature vary with elevation. Average annual rainfall ranges from 51 inches (1,295 mm) on the coast to as much as 150 inches (3,810 mm) in the interior. There is a dry season roughly from January to April and a rainy season from May to November. The mean temperature is about 80 °F (27 °C), with highs sometimes ranging into the upper 80s (31 °C) and lows into the upper 60s (20 °C).
