Peru has a varied terrain with a mixed climate across its different regions. The extreme altitude changes of the mountainous landscape mean that one part of the country may be experiencing freezing cold temperatures, while the coastal regions have sunny weather.

The Pacific coastal regions have an unusual, dry desert climate and experience little rainfall. The capital of Peru, Lima, is located a bit further inland and also has low rainfall. On the other hand, the mountainous and jungle regions experience heavy rains, particularly in the peak wet season from January to March.

Lightweight clothing is generally needed in summer, but in mountainous regions, warm thermal clothing is essential. Waterproof clothing is required in the rainy regions.
