Peru Natural Environment

Geography of Peru 

Peru is one of the most geographically diverse countries in the world, giving rise to varied landscapes including:

  • Dense jungle in the Amazon Rainforest
  • The Maranora and Ucayali Rivers marking the beginnings of the of Amazon River
  • The spectacular Andes Mountains with a peak height of 6768 meters
  • The Altiplano plateau, a dry basin running along the western side of Andes in southeastern Peru
  • Lake Titicaca, the worlds highest navigable lake
  • The Sechura Desert, one of the few deserts in the world that receives most of its precipitation in the form of fog
  • The Atacama Desert, the driest place on earth

For practical purposes, Peru’s geography can be broken into 3 natural regions:

  • Coastal Zone – a dry, hilly region with high cliffs overlooking the pacific ocean
  • The Highlands – the mountainous regions of Peru
  • The Eastern Lowlands – Peru’s portion of the Amazon Basin covering 60% of the country, where run-off from rain and glaciers on the eastern slopes of the Andes combine to form the Amazon, the world’s largest and longest river system in the world.

Peru Climate 

Out of a total of 32 different kinds of climates found here on Earth, Peru has 28 of them, including dense rainforest, icy mountains, humid savannas, cold plateaus, dry forests, and hot plateaus. Coastal Peru is usually sunny and dry, but receives quite a bit of sea mist and fog from April to November. Peru’s Highlands have a wet season (October to April) and dry season (May to September). During the dry season, the weather is clear and sunny, warm during the day, but very cold at night. In Peru’s Amazon basin, the climate is very regular, with temperatures remaining constant year-round.

Temperature

With 28 different climates in Peru, temperatures vary greatly. Costal Peru has summer and winter seasons, where temperatures vary from 19-26 degrees Celsius in mid-summer (January-February) to 15-19 degrees Celsius in mid-winter (July-August). The Highlands also have summer (rainy) and winter (dry) seasons. Daytime temperatures remain fairly constant at an average of 20 degrees Celsius, but temperatures cool down a great deal at night, slightly more so during the winter season. Average nighttime temperatures get down to 6 degrees Celsius in the summer and down to 0 degrees Celsius in the winter. The higher the altitude, the cooler it gets. Temperatures in the Amazon Basin are stable year-round and oscillate from 26 degrees Celsius to 40 degrees Celsius at any given time of the year.


Rainfall

Peru’s Andes mountain range forms a formidable barrier to the eastern moisture-rich winds, forcing clouds to rain on the mountain range’s eastern slopes as they rise. Consequently, rainfall is sparse on the western slopes and high planes of the Andes, as well as in Costal Peru where total precipitation can be as little as 0.5 cm of rain per year, mostly concentrated in the winter months of June to October. With the exception of the Andes’ eastern slopes, most of the Peruvian Highlands are dry, receiving between 5 and 15 cm of rainfall per year. Peru’s Amazonian basin, on the other hand, receives a great deal of rainfall with some places exceeding 380 cm per year. While it rains year-round, most of the downpour is concentrated in the months of January to June, the Amazon’s “rainy” season.

I went from Cusco to Machu Piccho trought the Inca Trail. It was really amazing, althougt it was very tired. My trip was 3 days sleeping in tents and 4 days walking. I went in the first days of November and the climate was template. Just a little rain and a lot of sun. I recomend this to adventurus persons who has great physical conditions.
