Climate / Weather Forecast

The Atacama Desert is the driest place on the earth. It receives an annual precipitation of 1 millimeter and on some occasions there have been no rains at all. Even the highly elevated mountains show no signs of glaciers. Some of the river beds are said to have been dry for more than 120,000 years now.  This high aridity of the Atacama can be explained as due to:

  1. Failure of moisture from the coastal range reaching the desert since it is located on its hind side.
  2. The Height of the Andes blocking the rain clouds from reaching the desert.
  3. An inversion that is created due to the South Pacific High and the Humboldt Current.

People and Culture

The Atacama is sparsely populated owing to its harsh climatic conditions. However, the ancient days have witnessed Pre-Columbian societies in the regions with oases and valleys. In Pre-Hispanic times the interiors of the desert were inhabited by the Atacameno tribe that was noted for its fortified towns known as pucaras. The modern times since the 18th century has seen the evolution of small mining towns due to the large nitrate and copper mines within the Atacama Desert. The most predominant language of this region is Spanish.
