Peru Weather and Climate

Geographical location

According to COUNTRYAAH, Peru is a state in the west of South America. It is about 1.3 million km² the third largest state of the continent. Due to the special landscape, it only has about 31 million inhabitants.

It has only about a tenth of the population density of Germany. The neighboring countries are Ecuador and Colombia in the north, Brazil in the east, Bolivia in the southeast and south. To the west, the Pacific forms the country’s natural border.

In addition to dry coastal regions, the country also consists of highlands and mountains. The majority of the country’s area is covered by the rain and cloud forest with 60%. The coastal region consists largely of desert. The Atacama Desert, which is the driest desert in the world, begins at the state border with Chile and extends up to the state capital Lima. North of Lima, the coastal region becomes a little greener as a little more rain falls.

The Andes, which form part of the American Cordillera, begin directly behind the narrow coastal region (called Costa). The Cordilleras are the largest fold mountains in the world and some of them are still volcanically active. They often consist of parallel mountain ranges, some of which are far apart in Peru.

In between is the Peruvian highlands and the famous Lake Titicaca. The mountain ranges are repeatedly interrupted by the mighty headwaters and tributaries of the Amazon, which flow away from the Pacific towards the Atlantic. The highest mountain in Peru is the Nevado Huascarán with 6768 meters.

The dense and almost impenetrable Peruvian rainforest begins east of the Cordilleras. The rivers flowing towards the Amazon are the only arteries here. The largest city in this region Iquitos with 400,000 inhabitants can only be reached from Lima by plane or by boat.
