Weather in Peru in January

January falls during the wet season in Peru, and the weather can differ a lot depending on the region. With its diverse geography—coastal areas, the Andean highlands, and the Amazon Rainforest—Peru experiences a range of climate conditions. Here’s a guide to what you can expect from the weather in Peru in January.

Is January a good time to visit Peru?

January in Peru gives you a unique travel experience. While it’s the peak of the wet season in many areas, the coastal regions have warm, sunny weather, perfect for beach days. 

The Andean highlands and Amazon rainforest, on the other hand, get a lot of rain, making the landscapes lush and vibrant, though it might affect some outdoor activities. 

Even with the rain, January is a great time to explore popular sites like Machu Picchu with fewer crowds. In August, you can enjoy the summer on the coast, experience local festivals, and see the Andes at their greenest. Just be ready for occasional weather disruptions in the highlands and higher humidity in the Amazon.

January: Sunshine, average temperatures, and rainfall

January in Peru marks the peak of the wet season, with weather varying significantly across different regions. Generally, the country experiences warm temperatures and increased rainfall, with average daylight hours ranging from 12 to 13 hours per day.  If you're still not sure where to head during your Peru trip, see our trip ideas gallery for more inspiration.

Coastal Region

The coastal areas (in places like Lima, Paracas National Reserve and Pisco) enjoy warm temperatures, with averages around 75°F (24°C). Rainfall remains minimal, typically less than 0.1 inches (2.5 mm). Lima, the capital, may experience occasional fog, known locally as "garúa."

Andean Region

In the Andean highlands (in places like Cusco, Lake Titicaca, and Huascarán National Park), temperatures are cooler, averaging around 54°F (12°C). Rainfall is significant, with approximately 5.5 inches (140 mm) of precipitation. Afternoon showers are common, while mornings tend to be clearer.

Amazon Rainforest Region

The Amazon basin (places like Iquitos, Tarapoto, and Pucallpa) is hot and humid during January, with average temperatures reaching 88°F (31°C). Heavy rainfall is typical, often exceeding 12 inches (305 mm). High humidity persists throughout the month.

What about the crowds & costs?

January is part of Peru's low season for tourism, especially in the Andean and Amazon regions because of the wet weather. This means fewer tourists at major attractions like Machu Picchu, giving you a more relaxed and intimate experience. On the flip side, coastal areas can be busier due to local summer holidays. You’ll likely find lower prices for accommodations and tours in the highlands and Amazon, while coastal resorts may still have peak-season rates. If you're okay with a bit of rain, January can be a great time to avoid the crowds and save money.

Explore Cusco's Plaza de Armas

While January is rainy in Cusco, it's a great time to explore the city's rich history and culture. Visit the Plaza de Armas, the heart of the ancient Incan capital, and explore nearby museums and churches. The rain often clears by afternoon. Or dive deeper into Incan history with a visit to the nearby Qorikancha.

Visit Machu Picchu in its lush glory

January's frequent rain means fewer crowds and a mystical, misty atmosphere at Machu Picchu. The surrounding landscapes are at their most verdant, which makes for stunning photo opportunities.

Discover Lima's culinary scene

January is an excellent time for food tours, cooking classes, and dining at top restaurants without the peak season crowds. Visit the Surquillo market for fresh produce and local ingredients. For fine dining, book a table at Central or Maido, both frequently ranked among the world's best restaurants.

Experience the Amazon Rainforest

January's wet season in the Amazon creates ideal conditions for wildlife spotting and river cruises. Higher water levels allow access to areas unreachable during drier months, which makes for a great opportunity to explore the rainforest's biodiversity.
