Term Insular climate

The climate of small islands or groups of islands, in which the ocean plays an influential role. The most important characteristic of island climate is the lack of seasonal temperature variations, particularly at low latitudes. The islands close to the Equator have average annual temperature variations of 1º C, while in temperate latitudes the average annual variation is less than 10º C.

The islands in the equatorial belt and the trade wind area, such as the Caribbean islands, belong to this type of climate, which is characterized by:

  • Insignificant seasonal variation.
  • Maximum air temperature (tbs) variation between 29º C and 32º C during the day and between 24º C and 27º C at night.
  • High relative humidity.
  • Annual rainfall ranges between 1,250 and 1,800 millimeters.
  • Sky conditions are clear or filled with irregular white clouds and high brightness.
  • Strong and direct solar radiation.
  • Trade winds or a steady wind  speed of 6 to 7 m/s prevail.
  • Vegetation is of a brighter color than in temperate-humid areas.
