Weather in Peru in October

If you're exploring busy cities, ancient ruins like Machu Picchu, or the Amazon jungle, knowing the weather is key for a successful adventure in Peru. Here's a breakdown of the weather in Peru in October to help you plan your trip.

Is October a good time to visit Peru?

October is a transitional month in Peru, so the weather varies depending on where you go. Coastal areas like Lima have mild temperatures and little rain, which makes it nice for exploring. In the Andes, including Cusco and Machu Picchu, you’ll get a mix of dry days and a few showers as the wet season starts to approach. 

The Amazon is warmer and rainier, making the rainforest especially lush. October gives you a chance to see Peru’s different climates—coasts, mountains, and rainforest—before the heavier rains set in, so it’s generally a good time to visit.

Sunshine, average temperatures, and rainfall

October marks the beginning of spring in Peru. The weather is generally mild, and it's a transition period from the dry season to the rainy season in some regions. Daylight hours continue to lengthen, averaging around 12-13 hours per day across the country. If you're still not sure where to head during your Peru trip, see our trip ideas gallery for more inspiration.

Coastal Region

The coast  (in places like Lima, Paracas National Reserve and Pisco) warms up, with temperatures averaging 70°F (21°C). Rainfall remains minimal at less than 0.1 inches (2.5 mm). Beach destinations become more appealing as temperatures rise.

Andean Region

The Andes (in places like Cusco, Lake Titicaca, and Huascarán National Park) experience milder temperatures, averaging 56°F (13°C). Rainfall increases to about 2 inches (51 mm). This marks the end of the peak dry season for Machu Picchu and other Andean sites.

Amazon Rainforest Region

The Amazon (places like Iquitos, Tarapoto, and Pucallpa) is hot, with average temperatures of 86°F (30°C). Rainfall increases to about 7 inches (178 mm). River levels begin to rise, making boat travel easier.

What about the crowds & costs?

In October, Peru is in its shoulder season, so you get a mix of good weather and fewer tourists. Places like Machu Picchu won’t be as packed as in the peak months (June-August), giving you a more relaxed experience. This lower tourist traffic usually means you’ll have more flexibility with reservations and might find better deals on hotels and tours. While prices aren’t at their lowest, they’re generally more reasonable compared to peak season.

Lord of Miracles Procession in Lima

This is one of South America’s biggest religious events. October is famous for the Señor de los Milagros (Lord of Miracles) procession in Lima, one of the largest religious processions in South America. Join thousands of devotees dressed in purple as they follow the revered image through the streets of Lima. This month-long celebration reaches its peak on October 18th and 28th.

Explore Colca Canyon before the peak rainy season

Take advantage of the last month of the dry season to visit Colca Canyon near Arequipa. October is the tail end of the dry season at Colca Canyon near Arequipa. It’s a good time to spot Andean condors in flight. You’ll also see colorful wildflowers against the terraced landscape, thanks to some early spring rain.

Fiesta de la Virgen del Rosario in Cusco

In October you can experience the Fiesta de la Virgen del Rosario in Cusco, typically held in the first week of October. This festival combines religious processions with traditional Andean celebrations, with colorful parades, folk dances, and local music. 

Spring birdwatching in Manu National Park

October is the start of spring, making it perfect for birdwatching in Manu National Park. As migratory birds return and resident species begin their breeding seasons, the forest comes alive with a symphony of calls and vibrant plumage displays. Expect lots of bird calls and colorful displays, plus lush greenery for great photography.

Catch the tail end of whale watching season in Máncora

Visit the northern beaches of Peru, particularly Máncora, to catch the final weeks of the whale watching season. Humpback whales can often be spotted off the coast until mid-October as they begin their migration back to Antarctic waters. Combine whale watching excursions with enjoying the pleasant beach weather.
