At only 19.6 miles long and six miles wide, Aruba has been nicknamed “One Happy Island” due to its idyllic climate and beautiful tropical beaches. Located in the southern Caribbean Sea, Aruba is known for its sunny weather year-round, though the trade winds prevent the tropical nation from ever feeling too hot in the summertime. Thanks to the island’s location outside the hurricane belt, Aruba is less likely to be hit by tropical storms any time of year, and there is relatively little rainfall compared to other Caribbean islands. Read on for seasonal weather and average monthly temperatures for Aruba, so you can best prepare for your trip.
