The climate of Aruba

Aruba experiences a hot semi-arid type of climate (Köppen climate classification BSh). The climate is tropical and remains hot throughout the year. Aruba is a tropical island and a constituent country of the Netherlands in the South Caribbean Sea. The Dutch Caribbean Island is just 18 miles north of Venezuela and 620 miles west from the main Lesser Antilles region. Aruba, Bonaire, and Curacao constitute the ABC Islands that lie outside the Hurricane Alley of the Caribbean. Northeast trade winds prevail for 9 months of the year to reduce the effect of the tropical sun. The proximity to the equator, trade winds, and the vast waters of the Caribbean Sea and the Atlantic Ocean influence the climate.

Aruba is a flat, small island, which lies just 12°N of the equator. The land area measures 180 square meters, with a diagonal length of 20 miles from the northwest to the southeast and maximum width of 6 miles. The landscape is arid and cactus-strewn, unlike the rest of the Caribbean. The vegetation is short, and there are no rivers, natural lakes, or streams on the island. The hinterland has few rolling hills, such as Hooiberg, with an altitude of 165 meters. The shore areas are mainly of limestone, rocky cliffs, and coral reefs. White sandy beaches dot the western and southern coasts in the protection of calm waters. Coral reefs and clear waters make the southern beaches a popular tourist destination. The northern and eastern coasts face rough seas due to strong ocean currents. Swimming is risky on the northern shores due to rocky coasts and strong currents. Mount Jamanota is the highest point in Aruba at 188 meters above sea level.
