Peru – Weather

Lima, Peru

Cusco, Peru

Although the Peru is in the tropics, its weather varies due to the geographical diversity (coast, highlands, Amazon) and to the cold-water current of Humboldt in winter and the warm water current El Niño in the summer. The following are the general weather patterns by region:

The Coast

The central and southern region of the Peruvian coast is generally sunny in the summer (November to May) and cloudy during the rest of the year. Temperatures vary between 68ºF and 86ºF during the summer and 50ºF and 68ºF during the winter. The northern region of the coast has sunshine almost all year with some rain between November and March.

The Andes

The Andes have usually a rainless winter that runs from April to October and a rainy season that lasts from November to March, being heaviest in January- February. In the highlands temperatures have accentuated variations during the day, with sudden temperature falls after sunset (sometimes up to 59ºF).

The Amazon

In the tropical forests it can rain all year round and there may be high temperatures. From November to May rain is heavier, rivers rise, but from May to September temperatures are generally milder but never cold, except in Madre de Dios (south) where cold air-masses move in from Bolivia -in the winter months and you may need to wear a jacket/sweater.

Average daytime high temperature in the Amazon is between 82F and 93F and the average nighttime low is between 62F and 73F. One can expect a tropical environment with unpredictable rain showers, hot and humid temperatures during the day with more comfortable temperatures during the night. The general weather conditions are warm and humid. Nevertheless in some areas cold fronts can sweep into the Amazon and push daytime highs down to 50F and the nighttime lows to 43F. Thus, always be prepared for cooler temperatures.
