Climate chart - Chiclayo
In Chiclayo, the fourth largest city in Peru, the climate is subtropical arid, with a hot season from January to April and a relatively cool season from June to November.
Chiclayo is located in the northern part of the Peruvian coast (or better, a short distance from the coast), in the Lambayeque region, and despite the position, about 6 degrees south of the Equator, the climate is arid, and also relatively cool in winter. This happens because of the cold marine current, known as Humboldt current, which flows along the coast of South America.
The landscape in the region is virtually desert, except in areas where the rivers flowing from the Andes are used to irrigate fields. To find somewhat green areas, you have to go to the east, at the foot of the Andes, where there are nature reserves, such as the Refugio de Vida Silvestre Laquipampa, where the altitude ranges from 300 meters (1,000 feet) in the southern part to almost 3,000 meters (10,000 feet) in the northern part; the Bosque Moyan - Palacio, where the altitude ranges from 350 meters (1,100 feet) to nearly 1,800 meters (6,000 feet); and the Reserva Ecologica Chaparri, more arid, located near the city, and whose altitude reaches nearly 1,400 meters (4,600 ft). In the northeastern part of the Lambayeque region, we are now in the Andean zone: Incahuasi is located at 3,000 meters (10,000 feet) above sea level.
Near the city, we find the archaeological complexes of Túcume, where there are 250 decaying brick pyramids, and of Sipán.
On the coast, there are seaside resorts such as Puerto Eten and Pimentel, where you can swim and surf.
Here are the average temperatures.

Rainfall is generally very poor, in fact, it is lower than 100 millimeters (4 inches) per year. However, from January to April, rare rains occur, which in the years of El Niño, the phenomenon of an abnormal warming of the Pacific Ocean to the west of South America, may become more abundant, though not at the level of Tumbes (which is located in the northernmost part of Peru, and whose climate becomes tropical during El Niño years).
In the most intense periods of El Niño, however, both rainfall and temperature increase: from January to April (or even May), the maximum temperatures can often reach 33/34 °C (91/93 °F), with peaks of 35/36 °C (95/97 °F). In 1997, the average of the highs for the whole year was 30 °C (86 °F). As for the rains, in 1982-83, 240 mm (9.4 in) of rain fell, while in 1997-98, 455 mm (17.9 in) fell. Although they are rare, heavy rains, when they are concentrated in a few hours, are dangerous and can cause flooding.
