The climate of Martinique

Martinique has a predominantly tropical rainforest climate (Köppen climate classification Af), with hot and humid conditions throughout the year. Rainfall is heavy and frequent, and the climate tends to be equatorial. Martinique is a French overseas territory in the Lesser Antilles of the West Indies in the eastern Caribbean Sea. The windward island lies directly between Dominica in the north and Saint Lucia in the south. Barbados lies in the southeast, and South America is in the southwest. The tropical latitudes, trade winds, and proximity to seas influence the climate. The proximity to the equator ensures an equal duration of day and night much of the year.

Martinique lies 14°N of the equator and is mostly volcanic and tropical. The volcanic island is 43 miles long and 19 miles wide and has a total of 436 square miles. The mountains and volcanoes of the Piton Conil, Mount Pelee, Morne Jacob, and Pitons du Carbet dominate the northern part of the island. Lush rainforests cover the mountainous terrain in many places. The windward coast consists of coastal cliffs, cays, and shallow reefs. The leeward coast is favorable to sea traffic with a steeply descending and deep sea bed. Corals and strong trade winds generally affect the windward side more than the leeward. The eastern coast has several small islands. The southern beaches of Les Salines are white and sandy in contrast to the grey and black northern sand beaches. Mount Pelee is the highest point at 1397 meters above sea level in Martinique.
