The geography and climate in the Caribbean region varies. Some islands in the region have relatively flat terrain of non-volcanic origin. These islands include Aruba (possessing only minor volcanic features), Barbados, Bonaire, the Cayman Islands, Saint Croix, The Bahamas or Antigua. Others possess rugged towering mountain-ranges like the islands of Cuba, Hispaniola, Puerto Rico, Jamaica, Dominica, Montserrat, Saba, Saint Kitts, Saint Lucia, Saint Thomas, Saint John, Tortola, Grenada, Saint Vincent, Guadeloupe, Martinique, and Trinidad & Tobago.
The climate of the region is tropical but rainfall varies with elevation, size and water currents (cool upwellings keep the ABC islands arid). Warm, moist tradewinds blow consistently from the east creating rainforest/semidesert divisions on mountainous islands. Occasional northwesterlies affect the northern islands in the winter. The region enjoys year-round sunshine, divided into ‘dry’ and ‘wet’ seasons, with the last six months of the year being wetter than the first half.
The waters of the Caribbean Sea host large, migratory schools of fish, turtles, and coral reef formations. The Puerto Rico trench, located on the fringe of the Atlantic Ocean and Caribbean Sea just to the north of the island of Puerto Rico, is the deepest point in all of the Atlantic Ocean.
Hurricanes, which at times batter the region, usually strike northwards of Grenada, and to the west of Barbados. The principal hurricane belt arcs to northwest of the island of Barbados in the Eastern Caribbean.
The region sits in the line of several major shipping routes with the man-made Panama Canal connecting the western Caribbean Sea with the Pacific Ocean.
