Weather in Peru
Peru's weather is extremely varied, thanks to the country's geographical diversity. The combined influence of the Andes Mountains, the Pacific Ocean and the Amazon rainforest creates unique climatic conditions. The country can be divided into three main climatic zones: the coastal plains, the Andes Mountains and the Amazon rainforest.
Coastal Plains
The coastal plain (Costa) stretches along the Pacific Ocean and is home to most tourist destinations. The weather here is relatively stable, warm and dry in summer (December-April), and cool and humid in winter (June-September).
Temperature generally ranges between 15-25°C, and rainfall is minimal.
Andes Mountains
The climate of the Andes Mountains (Sierra) varies depending on altitude. Pleasant, temperate climate prevails in the valleys, while the air is colder and drier at higher altitudes.
Most rainfall occurs in the summer months (November-April), while the winter months (May-October) are drier.
Daily temperature fluctuations can be significant, and it can freeze at night.
Amazon Rainforest
The Amazon rainforest (Selva) has a tropical climate, with high temperatures and rainfall year-round.
Temperature generally ranges between 25-35°C, and humidity is high.
Rainfall is variable but generally abundant. Most rain falls between November and April, but it can rain at any time of the year.
Best Time to Visit
The best time to visit depends on your planned route and activities. Generally, the dry season (May-October) is the best choice for visiting the mountains and coastal areas, while for the tropical rainforest, the less rainy period (June-September) is more ideal.
The dry season is recommended for visiting Machu Picchu and the Sacred Valley, as visibility is better and the chance of rain is lower.
