Cradle of countless civilizations of the past, Peru is an extraordinary nation of South America known throughout the world for preserving the legendary Cuzco which at the time of the pre-Columbian empire was known as the predominant center of Tahuantinsuyo, due to the archaeological site of Chavìn , for the ancient city of Machu Pichu and multi-ethnic cities like Lima. However, Peru also has an extraordinary naturalistic heritage made up of whitewashed mountains, endless deserts and even humid forests.
Peru is a country included in the belt that goes from the Equator to the Tropic of Capricorn, it gathers 11 different ecoregions and 84 habitats (of the 117 total that exist all over the world). Due to the geographical conditions and the great diversity of natural resources, it consequently also has a great variety of landscapes. So here is one useful guide to know the climate and the best period of Peru.

Best time

The Peruvian territory, as already announced, given its heterogeneity it is divided into three major regions, classified mainly on the basis of altitude: the Costa, the Sierra and the Selva.

  1. Costa (Lima): the ideal period would be summer (December-April), with a mild climate, without extreme cold or suffocating heat, with a preference for February-March
  2. Sierra (Andes, Arequipa, Cuzco): from April-May to October-November, despite a strong temperature range between night and day. The rainy season would affect trekking activities.
  3. Selva (Iquitos): it has two well-differentiated seasons, the one between April and October is preferred as there is little rain, an ideal time to travel as the volume of rivers decreases and the roads are easily passable

The best time to visit Peru is our summer (May to mid-September)except on the coast where our winter is best.

Period to avoid

The period between January and April is particularly rainy, for example, trekking lovers would risk finding themselves in the middle of the mud, even if by now many Peruvian fiestas continue undisturbed despite the incessant rain.

Furthermore, Peru is a nation located on the Pacific Belt of Fire, so it is possible that earthquakes can occur. Unfortunately, today it is not possible to program if and when they will happen so, if you are near the coast, when the ground starts to shake, pay attention to the tsunami risk.

Climate and seasons

Peru is located south of the Equator and therefore, also for this reason, it is possible to find three different climates in relation to the landscape characteristics: the long coast which has a mild climate, very cloudy and particularly foggy in the winter and hot in the summer , the area characterized by the Andes (the Sierra), on average cold depending on the altitude and finally the Selva, part of the Amazon forest, with a very hot and humid climate all year round.

Average Temperatures and Precipitation - La Costa (Lima)

The Peruvian coast faces the Pacific Ocean and it is divided from the nearby Sierra by the natural valleys created by the rivers. Although it has a long stretch of coastline, Peru is not a seaside destination, but is sought more for trekking and visits to cultural ruins.
The climate of this area is essentially mild all year round, with lows of 18 ° in August and highs of 24 ° in February, and it almost never rains. This is why the landscape is desert.
In Lima, however, in winter (June-September) the amount of sunshine is scarce, the sky is often cloudy and therefore there is a perception of cold greater than the real temperature.

Recommended period: from December to April with preference for February-March.

Average Temperatures and Precipitation - Sierra (Cuzco, Machu Picchu)

The Sierra area develops along the Andes chain, in the central part of Peru.
Here the rainy season is from September to May, and the dry season from June to August. However in the far south (Arequipa, Puno, Lake Titicaca) the dry season is longer and runs from May to September.
In this area there is a strong thermal excursion and during the dry season at night there can even be frosts in relation to the altitude. For example, in Cusco (3.300 meters) and on Lake Titicaca (3.800 meters) from May to September the temperature even drops below freezing. The situation on Machu Picchu is milder (2.500 meters)

Recommended period: from April-May to October-November, despite a strong temperature range between night and day. The rainy season would affect trekking activities.

Average Temperatures and Precipitation - Selva (Iquitos)

The area of ​​the jungle is the innermost of Peru and has the Amazon River basin: it is a vast flat and hilly area where you can find a very dense rainforest, therefore an almost completely uninhabited and uncontaminated area. The prevailing climate is the equatorial one, hot and muggy throughout the year, characterized by frequent and abundant rains in the northern area, while in the south, with the relatively dry winter season, it becomes tropical. July and August will be the least rainy months when it is easier for the sun to peek, however in the rest of the year the rains show up as an afternoon downpour.

Recommended period: between July and August the climate is almost perfect as the rains decrease considerably, with highs of 30 degrees. In general, the temperature will always be high, if not sultry.
