Peru’s Three Climate Regions
One of the reasons Peru is such an extraordinary destination is its geographical diversity. Within a single journey, travelers can experience coastal deserts, snow-capped mountains and tropical rainforest. Each region has its own climate, making Peru a fascinating destination at any time of the year.
The Pacific Coast
The Pacific Coast stretches from the northern beaches to the southern desert landscapes and includes destinations such as Lima, Paracas, Nazca and Trujillo.
Summer lasts from December to April, bringing warm temperatures, sunshine and ideal beach weather. During the winter months, from May to November, Lima often experiences cloudy skies and coastal mist known locally as garúa, although rainfall is extremely rare.
Average Temperature
- Summer: 24–30°C (75–86°F)
- Winter: 15–22°C (59–72°F)
Best for
- City breaks
- Gastronomy
- Coastal adventures
- Ballestas Islands
- Nazca Lines
The Andes Highlands
The Andes are home to Peru’s most famous destinations, including Cusco, Machu Picchu, the Sacred Valley, Rainbow Mountain, Arequipa and Lake Titicaca.
Rather than four seasons, the Andes experience two main travel periods:
- Dry Season: May–September
- Rainy Season: November–March
During the day, temperatures are usually pleasant, but nights can become very cold due to the altitude.
Average Temperature
- Day: 17–23°C (63–73°F)
- Night: 0–8°C (32–46°F)
Best for
- Machu Picchu
- Hiking
- Inca Trail

The Peruvian Amazon
The Peruvian Amazon is warm, humid and full of life throughout the year. Unlike the Andes, temperatures remain relatively stable, while rainfall varies depending on the season.
The dry season offers excellent jungle hikes, whereas the rainy season allows deeper navigation through flooded forests, creating exceptional wildlife viewing opportunities.
Average Temperature
- Day: 28–33°C (82–91°F)
- Night: 20–24°C (68–75°F)
Best for
- Wildlife
- Birdwatching
- River cruises
- Eco-lodges

Peru Weather by Season
Dry Season (May–September)

- Machu Picchu
- Cusco
- Sacred Valley

- Lake Titicaca
Rainy Season (November–March)

The Amazon flourishes during this period, offering excellent river excursions and wildlife experiences.

Shoulder Season (April & October)
April and October are often considered the best months for travelers looking to combine pleasant weather, greener landscapes and fewer visitors.
Does It Rain All Day in Peru?
No. One of the biggest misconceptions about Peru is that rain lasts all day.
In the Andes, rainfall is usually concentrated in the afternoon or evening, while mornings often begin with clear skies. On the Pacific Coast, especially in Lima, rain is extremely uncommon. Instead, winter brings a light coastal mist called garúa.
In the Amazon, showers can occur at any time, but they are typically brief and are part of the rainforest ecosystem.
