What Makes the Difference

The Influence of the Pacific Currents on Chile’s Climate

Chile’s climate is highly influenced by the cooling effect of the Pacific Ocean and the Humboldt Current that begins in the icy waters near Antarctica and flows up the western coast of South America. Curiously, when the effect of the Humboldt’s cold current hits Chile’s northern coastline it produces clouds and fog, but little or no precipitation, which then contributes to making the Atacama Desert the driest on Earth!

 

Chile’s Unique Geography

The cool sea air is partially blocked by the Coastal Mountains, although it finds its way inland by following the course of the transversal river valleys.

During the day, sea breezes carried by the cold Humboldt Current penetrate inland, and each night, cold air descends from the snow- covered peaks of the Andes.
