Don't Be Serious About Aruba Weather Forecasts ! ! !...
Where the Aruba weather forecasts are concerned, they are not reliable to say the least. Ask anyone who has followed the reports prior to their Aruba vacation and the weather forecast always says a "chance of showers". Weather forecasters are betting on random rain cloud which will deliver a passing shower. It will not even be enough to make you leave the beach! You will find there are no two weather forecasts which are exactly the same.
In scientific terms, Aruba has a semiarid hot climate. Let us just call it a desert island with very little rain. There is a very clear difference between dry and rainy seasons. Rainy seasons runs September into January. During the wet season, rain showers in Aruba fall mainly at night or early in the morning.
There are very few days on the island which are a total washout. The average rainfall October through December is 4.1 inches versus March through May when the average is .8 inches. Aruba's dry season begins in February and continues through June. For the lowest average cloud cover, plan your vacation during the month of February. May has the highest average cloud cover, however rainfall during May is only slightly above a 1/2 inch. The island also has sustained easterly tradewinds to keep things comfortable.
