, 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
, 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
, 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
, where the altitude ranges from 350 meters (1,100 feet) to nearly 1,800 meters (6,000 feet); and the
, 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.
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
, 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
(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.
in Chiclayo is generally good, but it is not excellent, in fact, the Humboldt current can cause low clouds and fog, especially during the cool season, from June to August, though less so than in Lima.
Normally, the sea in Chiclayo is not very warm: it is warm enough for swimming in February and March, while it is very cool from July to November, when it drops to 18/19 °C (64/66 °F). However, in El Niño years, the sea in this area warms up a lot, so much so that it can reach 29 °C (84 °F) in the early months of the year.
