Some tropical countries include Mexico and Venezuela in the Americas. Some tropical countries from the Caribbean include Anguilla and Jamaica, whereas Angola, Cameroon and Ghana are some of the tropical countries in Africa.
Tropical countries are those that lie within the region called the tropics, which refers to the area of the Earth surrounding the Equator. It is limited in latitude by the Tropic of Cancer in the northern hemisphere at approximately 23.4 degrees north and the Tropic of Capricorn in the southern hemisphere at 23.4 degrees south. The tropics include all the regions on the Earth where the sun reaches a subsolar point (a point directly overhead) at least once in the solar year. The tropical areas are struck by the sun’s perpendicular rays at noon on a minimum of one day each year.
A large section of the world lies within the tropics. Tropical countries within the Western Hemisphere include Mexico, all of Central America, all of the Caribbean islands starting from south of Nassau in the Bahamas and the upper half of South America, including Ecuador, Peru, Colombia, French Guiana, Suriname, Guyana and Venezuela, as well as the northern part of Chile, Argentina, Brazil and Paraguay. In Africa, Morocco and Tunisia in the north and Swaziland and Lesotho in the south are the only countries that are not at least partly in the tropics.
