Quick Summary

Peru is traditionally divided into three main regions: the Costa, the Sierra, and Amazonia. The Costa is a coastal desert region along the Pacific Ocean, characterized by dry conditions due to the Andes blocking rain and the cold Peru Current. Despite the dryness, winter fogs provide some moisture for vegetation. Temperatures on the Costa are moderate, ranging from 66°F (19°C) in winter to 72°F (22°C) in summer. The Costa varies in width, with more level land in the north and narrower valleys in the south. This region is home to major cities like Lima, Trujillo, and Chimbote, which have experienced significant urban growth.1234
