The Caribbean Sea sits below the Gulf of Mexico bordering the Atlantic Ocean to the east and Central and South America to the west. The Wider Caribbean Region is made up of 35 countries and territories
The water of the Caribbean is warm, clear and has lower salinity levels than the neighbouring Atlantic. The average water temperature is around 27°C (80°F) and varies as little as 3°C (37°F) throughout the year.
The Caribbean Sea is the source of the Gulf Stream, with this tropically warmed current reaching right across the Atlantic.
