The Peru climate is marked by the different regions of Peru and hence their location. As Peru can be largely divided into three regions; the Coast, the Andean Highlands and the Amazon Basin, it is clear that all these regions present different climates and temperatures.
The Peruvian Pacific Coast, more than 2000Km long is mainly made up out of desert. This desert, the outskirts of the worlds driest desert, the Atacama Desert in Chile, brings along several of the typical characteristics of a desert climate. Very dry, warm days and somewhat colder nights are something that can be found for large parts of the year on the coastal area of Peru. Peru temperatures for this region do differ somewhat from month to month, but in general day temperatures are warm and dry. The temperatures here are in general warm all year round with higher temperatures from December to March, when the summer hits. As this is the case for most of the Northern and Southern Coast, Lima does have another phenomenon having a rather large influence on the climate in the capital. As the Humboldt Current comes close to land in the Lima area, bringing cold water that clashes with the warm air coming from the mainland. This creates a strange kind of smog, covering large parts of the city, especially the coastal districts.
The Peru weather in the Andean highlands depends largely on the altitude. As the Andean mountain range in Peru reaches tops over 6000m, it is clear that this an important factor when it comes to climate. The Andean Highlands, as the rest of Peru, has two seasons; the dry season and the wet season. The dry season is from April to late October, having very little rain and plenty of strong sun. The days are very nice and quite warm, due to the sun, but in the evening the nights are colder than in the wet season due to the clear skies. The wet season starts around mid November, with its highpoint mostly around January / February. Rain is mostly at night but cannot be discarded during the days. Especially February can have pretty heavy showers. On the eastern slopes of the Andes towards the Amazon basin, the Peru weather changes with the altitude you would come down. As you will quite rapidly transfer from highlands to Rainforest, the temperatures and especially humidity levels will increase quickly, the more you go down.
Once in the Amazon Basin, you have reached the third and largest Peru weather zone in the country; the Amazon Rainforest. This area is also known for having two seasons, with as main difference the quantity of rain. Even though the Amazon Rainforest can have showers all year round, the west season (December – February) does contain more rain, making it a bit better to see wildlife. Temperatures are warm all year round, but drop a bit around June / July. Humidity levels are quite high and rise in the wet season a bit.
This is just a small summary of the Peru weather and the Peru temperatures in the three main regions. Another Peru climate factor is “ El Niño” a 3-5 yearly returning weather phenomenon provoking higher temperatures for some and more rain for other regions.
