When to Go

Best Time to Visit Atacama Desert (San Pedro)

South America · Month-by-month weather, seasons and what to do — from Noura's Destination Finder.

Noura's timing tip: San Pedro sits at 2,400 m and tours climb to 4,300 m at El Tatio and the altiplanic lakes, so acclimatize before geyser trips; the Jan-Feb 'invierno altiplanico' can bring flash floods that close the El Tatio and lagoon roads.
