The climate of Dominican Republic

The Dominican Republic has a tropical climate with hot, wet summers and warm, dry winters. The northern coastal and lowland regions have a tropical rainforest climate (Köppen climate classification Af). The south-central region has a tropical monsoon (Köppen Am) climate, while the south is a tropical savanna (Köppen Aw). A few areas in the west have an oceanic climate (Köppen Cfb). The Dominican Republic occupies two-thirds of the island of Hispaniola in the Greater Antilles of the West Indies. Haiti shares the remaining one-third in the west, the Bahamas and the Turks and Caicos Islands lie to the north and northwest, and Puerto Rico is in the west. The tropical latitudes, trade winds, and the vast waters of the Atlantic Ocean and the Caribbean Sea chiefly influence the climate.

The Dominican Republic has a diverse topography with four important mountain ranges. The Cordillera Central is the highest mountain range in the West Indies. The fertile Cibao Valley lies between the northern and central mountain ranges. The semi-arid San Juan Valley lies south of the Cordillera range. Much of the area near the Enriquillo Basin has a hot and arid climate (Köppen BSh). The Caribbean Coastal Plain is the most extensive plain in the country and stretches in the north and east of Santo Domingo. The Yaque del Norte, Yuna, San Juan, and Artibonito are the four major rivers in the country. Lakes, lagoons, mangroves, and cays are essential parts of the island's ecosystem. Pico Duarte is the highest peak in the Caribbean at 3098 meters. Lake Enriquillo, a saltwater lake at 45 meters below sea level, is the lowest elevation in the Caribbean.
