 A high amount of moisture or vapor in the air makes hot temperatures feel hotter.This quantity of moisture is due to different factors – the extraordinary evaporation from the seas that surrounds the country on all sides, to the different prevailing winds in the different seasons of the year, and finally, to the abundant rains so common in a tropical country.The first may be considered as general causes of the great humidity, which is generally observed in all the islands throughout the year.
