Sierra

The Andes shelter the largest variety of climates in the country. The climate is semi-arid in the valleys and moist in higher elevations. Rainfall varies from 200 to 1,500 mm  per year. The rainy season starts in October and ends in April.

The western slopes are arid to semi-arid and receive rainfall only between January and March. Temperatures vary between 5 and 15 °C in the night versus 18 to 25 °C  in the day.

Between 2,500 and 3,500 meters the temperatures vary from 0 to 12 °C  in the night and from 15 to 25 °C during the day. At higher elevations from 3,500 to 4,500 meters, the Puna ecoregion, the temperature varies from −10 to 8 °C during the night versus 115 °C  during the day.  The northernmost regions of the Andes around 
Cajamarca and Piura regions have Paramo climates.

Costa/ Coast

Peru is divided into three regions : Costa, Sierra, and Selva.

COAST

The Peruvian coast is a microclimatic region. 

The central and southern coast consists of a subtropical desert climate composed of sandy or rocky shores and valleys. Days alternate between occasional fog in the winter and sunny skies with some haze in the summer. Temperatures rarely fall below 12 °C and do not go over 29 °C. An exception is the southern coast, where it does get a bit warmer and drier for most of the year during daytime, and where it can also get much colder during winter nights 8°C. One must not forget that although it may not be as warm as typical tropical latitudes, the sun will hit and strike as if you were in any other tropical place.

The northern coast, on the contrary, has a curious tropical-dry climate, generally referred to as tropical savanna. This region is a lot warmer and can be unbearable during summer months, where rainfall is also present. The average temperature is 25 °C.
