Quick Facts

  • The Atacama Desert is one of the driest regions on the earth; just to get some perspective — it is 50 times drier than the Death Valley in California. Some areas of the desert have not seen any rainfall in over 400 years.
  • Its unique location between two mountain ranges is responsible for the extreme aridness; the desert lies entirely in a rain shadow region and the ocean currents and winds from the Pacific blow cold dry air further into the Atacama Desert.
  • High season: December – February (Summer)
    The most popular season for visiting the Atacama Desert are the summer months of December, January, and February. The pleasant day temperatures and warmer nights make for a wonderful time to explore the desert.
  • Low season: June – August (Winter)
    Winter brings low night temperatures and the possibility of winter storms, making the months from June to August less ideal for a visit to the Atacama Desert.
  • Shoulder season: September – November (Spring) / March – May (Fall)
    Fall and spring in the Atacama Desert are shoulder seasons accompanied by good temperatures and fewer tourists.

Most visitors make the oasis region of San Pedro de Atacama their base and the area’s few hotels are often expensive and full in the high season. Guided tours are difficult to come by, as most of the tours to Atacama Desert book up fast.

Apart from being the driest desert, Atacama is also one of the oldest deserts in the world. The area has been dry for more than 40 million years and the dramatic landscape is without greenery, buildings, infrastructure or pollution. A photographer’s dream and a traveler’s paradise, Atacama’s mesmerizing landscape is sure to delight even the most experienced of travelers. Summer is undoubtedly the best time to visit the Atacama Desert to get the most out it, and its popular activities. However, considering the shoulder season for a fantastic holiday in the desert isn’t a bad idea either.
