The best time to visit Argentina’s high desert is generally from April to October, during the drier months when clearer skies and more stable weather can make travel easier. These conditions are also favorable for photography and road trips, particularly when exploring remote areas of the Puna. Summer rainfall, especially in January and February, can affect road conditions and access to isolated locations. Because of the region’s high elevation, temperatures can remain cool throughout the year, with much colder conditions at night.
