Country Summary

This page presents high-level information for Peru's climate zones and its seasonal cycle for mean temperature and precipitation for the latest climatology, 1991-2020. Climate zone classifications are derived from the Köppen-Geiger climate classification system, which divides climates into five main climate groups divided based on seasonal precipitation and temperature patterns. The five main groups are A (tropical), B (dry), C (temperate), D (continental), and E (polar). All climates except for those in the E group are assigned a seasonal precipitation sub-group (second letter).  Climate classifications are identified by hovering your mouse over the legend. A narrative overview of Peru's country context and climate is provided following the visualizations.

With GNI per capita of US$5,975 in 2015 (2011 PPP), Peru is one of the largest economies in Latin America and the Caribbean (LAC). Peru’s rapid economic growth, averaging 5.3 percent since 2001, was second only to Panama’s in LAC. Its population of about 31 million is relatively young, with more than half being under 30 years. Peru’s geography is incredibly diverse, with the massive Andean cordillera dividing its surface into three natural regions: the Costa (arid coastal plains, where about 55 percent of the population resides) to the west; the Sierra (highlands, with 32 percent of the population); and the Selva (the lush Amazon rainforest, with 13 percent of the population) to the east. The country’s latitude, its mountain ranges, sharp variations in topography, and the Humboldt (ocean) Current create dramatically different climatic zones. Its geographic diversity exposes Peru to natural hazards—it has seven of the nine possible characteristics that make a country vulnerable to natural disasters: earthquakes, flash flooding, landslides, and volcanic activity, among them.
