When traveling to Peru, it’s important to understand that the climate can vary significantly from one region to another, and you shouldn’t assume that the weather in one area reflects the weather in the other regions in the country. Each region’s climate is heavily influenced by its elevation. For example, while it may be summer in Cusco, it doesn’t mean that the same applies to Lima, which is located on the coast at a much lower elevation. In fact, coastal regions like Lima have a mild, desert-like climate, whereas the Andean highlands experience cooler temperatures, even during the summer months.
