The Coast



Which features deserts, beautiful beaches and fertile valleys.

The Peruvian coastline is formed by a long snaking desert hemmed in between the sea and the mountains. The Andes to the east and the cold Humboldt sea current that runs along the coast are what make this area so arid. From the Sechura desert to the Nazca plains and the Atacama desert, the dry coastal terrain is occasionally split by valleys covered by a thick layer of cloud and drizzle in the winter.

Humidity in these areas produces a sensation of cold, although temperatures rarely dip below 12°C. During the summer, meanwhile, the sun beats down and temperatures often top 30°C. The central and southern sections of the coast feature two well-defined seasons: winter from April to October, and summer from November to March.

The north coast, meanwhile, is not touched by the effects of the cold current, which means it enjoys 300 days of sunshine a year and warm temperatures all year-long (as much as 35°C in the summer). The rain season runs from November to March.
