Costa : Presenta la forma de un extenso y árido desierto. La costa central y sur poseen dos estaciones : una invernal (abril a octubre) y una estival (noviembre a marzo). Durante el invierno una densa capa de nubes cubre los cielos y son frecuentes las lloviznas ligeras, la temperatura raramente baja de 12° C.; pero durante el verano, el sol brilla con fuerza y la temperatura alcanza con frecuencia los 30° C. La región norteña de la costa, por su parte, no sufre el efecto de las aguas frías, tiene casi 300 días de sol y temperaturas cálidas a lo largo del año (hasta 35° C en verano). Entre noviembre y marzo se presentan lluvias, en esos meses se incrementan marcadamente con la presencia del fenómeno climático El Niño.

 Coast: 
It presents the form of an extensive and arid desert.  The central and  south cost  possess two stations:  winter  (April to October) and  summer  (November to March).  During the winter, there is a dense layer of clouds, it covers the skies and there are frequent light drizzles, rarely low  temperature of 12° C. ; but during the summer, the sun shines strongly  and the temperature reaches often  30° C.  The northern region of the coast, does not suffer the effect of the cold waters, has almost  300 days of sun and hot temperatures along the year ( 35° C in summer).  Between November and March, rains appear in those months are markedly  increased with the presence of the phenomenon climatic “The Boy”. 

High Mountain:
The High mountain presents two climatic stations well differentiated: one of summer (April to October), characterized for sunny days, very cold nights (the freezes) and absence of rains (November to March), with abundant rains.  A feature that characterizes this region is the marked variation of temperature along the day.  Is common to be provided with temperatures up to  24° C at midday and as low as –3° C by the early morning.  The High mountain  also provided, a dry and  a  pleasant  weather; ideal for the growth of an enormous variety of cultivations. 

Forest: 
The forest can be divided into high forest  or eye brow mountain (on the 700 m. a.s.l.) and low forest (under 700 m .a.s.l.).  The first one possesses a temperate and subtopic climate, with abundant rains (November to March).  The nights are always fresh.  The low forest offers two climatic stations.  The station of summer or vaciante (visitor) (April to October) ideal epoch for the tourism, with sunny days and highly temperatures, often over the 35° C.  In these months the rivers diminish their volume and the highways are easily passable.  The station of rains (November to March) is characterized for frequent downpours and a deterioration of the terrestrial walking.  The humidity in the forest is very high along the year.
