The Atacama Desert (Spanish: Desierto de Atacama) is a desert plateau located on the Pacific coast of South America, in the north of Chile.Stretching over a 1,600-kilometre-long (1,000-mile) strip of land west of the Andes Mountains, it covers an area of 105,000 km 2 (41,000 sq mi), [2] which increases to 128,000 km 2 (49,000 sq mi) if the barren lower slopes of the Andes are included.
Southward is the Peruvian coastal desert which becomes at an indefinite location the Atacama Desert which continues into Chile. The Sechura is warmer and less impacted by the cloud cover that characterizes the more southern parts of the coastal desert, but there is a uniformity in precipitation along the entire coastline with less than 30 mm (1 ...
The cold Humboldt Current and the Pacific Anticyclone are essential to keep the dry climate of Atacama Desert. The average rainfall in the Chilean region of Antofagasta is just 1 mm per year. Some weather stations in the Atacama have never received rain. Evidence suggests that the Atacama may not have had any significant rainfall from 1570 to ...
The desert climate or arid climate (in the Köppen climate classification BWh and BWk) is a dry climate sub-type in which there is a severe excess of evaporation over precipitation. The typically bald, rocky, or sandy surfaces in desert climates are dry and hold little moisture, quickly evaporating the already little rainfall they receive.

The Atacama Desert coast is subject to a climate of extreme aridity, and therefore generates a low average annual rainfall of 3.4 mm (0.13 in) (1970–2000), and the Town of Antofagasta itself receives an annual average of less than 0.1 mm (0.004 in) of rainfall per year, earning it the record as the world's driest town.
