Climate & Weather Guide in Peru

Peru has one of the most climatically diverse landscapes in South America, with an extremely dry Pacific coast, cool and highly variable Andean highlands, and hot, humid Amazon lowlands. The country’s climate is shaped by altitude, the Andes rain shadow, and the cold Humboldt Current, so conditions can change dramatically over relatively short distances. For residents and expats, there is no single national climate profile; comfort depends strongly on region and elevation. The country spans roughly 1.28 million km², which supports multiple Köppen climate types including arid coastal desert, temperate highland, tropical rainforest, tropical monsoon, and tropical savanna conditions.
