The Best Time to Visit Peru

In the high mountains, we typically encounter sunny days with daytime temperatures ranging between 65°F and 70°F degrees, dropping to the 40s and lower at night. The sun is strong at high altitude, and it’s often warm enough to hike in shorts and a T-shirt. However, it can also get extremely cold—even in the daytime, if the sun slips behind a cloud—and nighttime temperatures can drop to below freezing. Mountain weather is unpredictable and sudden storms can occur, especially on high mountain passes.

April through early May is shoulder season—an especially good time to visit Machu Picchu and the Sacred Valley, which are lush and green from the rainy season. October and November are also the shoulder season and some of the best months to visit Machu Picchu—you’ll encounter fewer crowds, the landscape is greener, and the archaeological site takes on a dramatic atmosphere with occasional mist and cloud formations. Rain is possible but rarely an all-day event.

When packing for Peru, layers are key, especially in the highlands. Pack T-shirts along with fleeces and rain shells, and bring sun protection (hat, sunscreen, sunglasses) for high altitude, warm layers for cold nights, and sturdy hiking boots for trail days. In the Amazon, lightweight moisture-wicking clothing, insect repellent, and a rain jacket are essentials.

While Peru’s climate varies by region, it’s generally warm or mild year-round, especially in the Amazon and coastal areas like Lima. In the highlands, like the area around Machu Picchu, daytime temperatures are mild year-round and cool at night. While the Andes can be mild during summer days, they’re also quite cold at night, even in the summer.

January through March are the wettest months; we do not recommend visiting during this time. April through early May is shoulder season—an especially good time to visit Machu Picchu and the Sacred Valley, which are lush and green from the rainy season.

Cusco is one of the Peruvian cities with the best weather, boasting mild year-round daytime temperatures in the mid or high 60s and sunny days most of the year. Other cities with great weather include Arequipa, with its warm temperatures in the 70s, and Huánuco, with its always sunny skies and mild temperatures.
