The climate of Peru due to its considerable extension from north to south and to the difference in height between the various areas of the country is very varied. The climate of the country is greatly influenced by the presence of the Andes chain and that of the cold Humboldt current along the coasts of the Pacific ocean.

In general we can say that along the coast of Peru the climate is arid sub-tropical with very little rainfall. Along the Andes range, the climate has two seasons, a rainy summer and a dry winter. The Amazon area has hot humid climate with rains all year round and a relatively dry short season between June and August.

THE CLIMATE OF LIMA

The climate of the capital Lima is mild, sub-tropical desert, and is influenced by the cold Humboldt current, which ensures minimum average temperatures ranging between 12 ° C / 20 ° C and maximum average temperatures of 25 ° C / 30 ° C.

The rains are practically absent with an annual average of 13 mm, while the humidity is very high, this causes the rather continuous presence of the fog especially between May and November.

THE CLIMATE OF THE PERUVIAN ANDES

The climate of the Peruvian Andes is very varied and greatly influenced by altitude. In general the rainy season occurs between December and April, but their intensity varies considerably from area to area, for example along the south-western Andes there are between 200 and 500 mm of rain per year, while on the eastern side rainfall exceeds 1,000 mm per year.

WHEN TO GO TO PERU

The best time to visit Peru are the months of July to September, which correspond to the dry season along the Andean mountain range. For the coast, however, the best period is the sunny and humid months between December and March, when the coast is free from the cold fog that instead covers it for the rest of the year.
