In Talara, the climate is arid subtropical, with a hot season from January to April, and a relatively cool season from June to November.
Talara is located on the north coast of Peru, in the region of Piura, and 4 degrees south of the Equator. We are in the westernmost tip of the South American continent. The coool Humboldt Current flows on the sea, and is capable of affecting the climate, making it much more arid than other areas located at the same latitude, and also cooler.
Here are the average temperatures.

In this coastal area of northern Peru, which includes the regions of Piura and Lambayeque, we find the Sechura Desert; the landscape in the region is in fact practically 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.
Precipitation is usually very poor, as it's lower than 50 millimeters (2 inches) per year, but from January to April, rare rains occur, which in the years of El Niño, the phenomenon of an abnormal warming of the waters of the Pacific to the west of South America, may become more abundant.
In the most intense periods of El Niño, the rains increase dramatically, becoming frequent and sometimes even torrential. For example, in 1983, even 1,495 mm (59 in) of rain fell from January to early June, while in 1997/1998, 1,275 mm (50 in) of rain fell from December to April.
Here, however, is the average precipitation.
