Barbados is not in Jamaica. Jamaica and Barbados are separate islands. Jamaica is located in the Caribbean Sea slightly south of Cuba while Barbados is northeast of Venezuela, South America.
The Barbados Tourism Encyclopedia indicates that although Barbados is considered the easternmost Caribbean island, it is situated completely within the Atlantic Ocean. The island is 21 miles long and 14 miles wide. The western and southern coasts are characterized by quiet ocean waters and beaches while the northern coast features rocky cliffs. Barbados receives a steady flow of the northeast trade winds, and daytime temperatures run between 75 and 90 degrees Fahrenheit. The island has over 3,000 hours of sunshine annually.
