Located just outside the
hurricane belt, Aruba benefits from a tropical marine climate that varies little seasonally, with an average annual temperature of 27°C
(80.6F), varying from about 26°C
(78.8F) in January to 29°C
(84.2F) in July.
Most rain brought by the prevailing easterly winds of the region falls on the Windward Islands of the Lesser Antilles, leaving Aruba with a very dry climate.
Rainfall averages 510 mm (20.1 in) or less annually, and the island’s residents rely on one of the world’s largest desalination plants for most of their drinking water.
The rainy season occurs between October and December.
