Aruba is a generally flat, riverless island in the Leeward Antilles island arc of the Lesser Antilles. Aruba is renowned for its white, sandy beaches on the western and southern coasts of the island, relatively sheltered from fierce ocean currents, and this is where most tourist development has taken place. The northern and eastern coasts, lacking this protection, are considerably more battered by the sea and have been left largely untouched by humans. The hinterland of the island features some rolling hills, the best known of which are called Hooiberg at 165 meters (541 ft) and Mount Jamanota, the highest on the island at 188 metres (617 ft) above sea level. Oranjestad, the capital, is located at.
To the east of Aruba are Bonaire and Curaçao, two island territories which form the southwest part of the Netherlands Antilles; Aruba and these two Netherlands Antilles islands are sometimes called the ABC islands.
The isothermal temperature of Aruba's pleasantly tropical marine climate attracts tourists to the island all year round. Temperature varies little from 28 °C (82 °F), moderated by constant trade winds from the Atlantic Ocean. Yearly precipitation barely reaches 500 mm (19.7 in), most of it falling in late autumn.
