Weather in Peru

Lima's location on the coast of Peru makes it a popular spot for those who want to vege out, relax on the beach and swim in the Pacific Ocean. The fact that it almost never rains in Lima has also helped make this sunny spot a must-visit when visiting Peru. 

While it might not experience heavy rainfall, Lima does see cold temperatures and high humidity levels from June to September with an average of 1 hour of sunlight per day in each winter month. Summer (December to March) brings with it sunny conditions and average high temperatures of 79°F/81°F. 

Similar to other regions in Peru, temperatures in Cusco hardly differ during the year with the average high being around 70°F or 72°F every month regardless of season. If you're looking for the warmest time to visit Cusco, try traveling in the spring months of March, April and May before the rainy season starts. 

While summers are pleasant in Cusco, winters can get bitterly cold with low average temperatures of 34°F expected in July. You won't need to bring an umbrella but you'll need to pack thermal clothing, scarves, gloves and beanies if you want to keep warm, especially at nighttime. 

Located on the western slope of the Andes, Arequipa enjoys relatively dry conditions, only seeing around 3.7 inches of rain each year on average. January and February experience the most rain, while there are plenty of months that see no rainfall at all (May, June, July and October). 

Despite the city experiencing dry conditions, it rarely gets super hot, instead enjoying relatively mild temperatures throughout the year. However, temperatures can drop to a chilly 48°F from June to September, so remember to bring a coat or jacket with you if you're traveling during these months. 

Expect a lot of rain if you're traveling to Iquitos, located in the country's mountainous region to the north. Iquitos experiences around 112 inches of rain a year, with March and April being the months with the most rainfall. If you're looking to escape the rain, you can't. Even the least rainiest month (August) still experiences 6 inches. 

But just because it's rainy doesn't mean it's cold. The average high temperature in Iquitos is a sweltering 88°F, while the average low temperature doesn't dip below 70°F throughout the year.
