Aruba is a small Caribbean island (54 sq mi or 140 km2) about the size of Washington, D.C., located 25 km north of the coast of Venezuela and 68 km northwest of Curaçao, the largest island of the Kingdom of the Netherlands. Aruba’s terrain is mostly flat with a few hills. There is little in the way of vegetation or outstanding physical features and no inland water. Aruba’s best-known geographical feature is its white-sand beaches, which are the basis of an active tourism industry that is the mainstay of the island’s economy. Aruba is situated on the Caribbean Tectonic Plate. Aruba, as well as the rest of the ABC islands and also Trinidad and Tobago, lies on the continental shelf of South America, and is thus geologically considered to lie entirely in South America.

The core of the island is made up of Turonian submarine and subaerial basalts which were formed in the Caribbean large igneous province. These basalts were intruded by a tonalite pluton shortly after their eruption. The shore areas are mainly limestone-capped hills and ridges, with cliffs on the northern and northeastern coasts and coral reefs on the southern coast.

Mountains and Hills

Aruba’s terrain is almost entirely flat. The highest elevation, so-called Mount Jamanota, is only 188 m above sea level. Rock formations characterize the interior of the island. (www.countyreports.org)

The Coast and Beaches

Aruba has three deepwater harbors located at Oranjestad, Barcadera, and San Nicolaas (Sint Nicolaas). The coastal area is known for its white-sand beaches and the calm waters surrounding Aruba are clear, making it a popular tourist destination.

Climate

Temperature

Aruba’s semi-arid tropical marine climate varies little seasonally, with an average annual temperature of 27 °C (80.6 °F), varying from about 26 °C (78.8 °F) in January to 29 °C (84.2 °F) in July.

Rainfall

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.
