Wondering when is summer in Peru and what the season is really like? Peru’s summer runs from December to March, bringing warm temperatures, sunny coastal days, and a completely different climate from the Andes and the Amazon. Because Peru is in the Southern Hemisphere, its seasons are the opposite of the U.S. and Europe – meaning that while northern countries are in winter, Peru is welcoming its hottest months.

In this guide, you’ll learn exactly when summer happens in Peru, how the weather changes by region, the best places to visit, what to expect during these months, and essential tips to make the most of your trip. Let’s dive into everything you need to know about Peru’s summer season so you can plan the perfect vacation.
What Months Are Summer in Peru?
Summer in Peru lasts from December to March, a period marked by warm temperatures, long sunny days on the coast, and increased humidity in many regions. Because the country is located in the Southern Hemisphere, these months correspond to winter in the U.S. and Europe, making Peru an ideal destination for those seeking sunshine during the colder northern months.
Although the season officially spans four months, the intensity of summer varies depending on the region. The coast experiences its hottest and driest period of the year, while the Andes and the Amazon maintain warmer days but also face occasional rains. This contrast makes Peru a diverse destination with multiple climatic experiences during the same season.
Summer season in the Peruvian coast
The Peruvian coast enjoys its best weather of the year during summer. From December to March, the coastline shifts from cloudy gray skies to bright sunshine, higher temperatures, and refreshing ocean breezes. Cities like Lima, Paracas, Trujillo, and the northern beaches become vibrant spots for swimming, surfing, and outdoor activities.
This is the peak season for beach tourism, especially in the northern region, where the sea is warmer and conditions are perfect for water sports. Restaurants, boardwalks, and coastal towns come alive with seasonal events, making the coast the most popular region to enjoy Peru’s summer.
Summer weather in Lima, Paracas, and the northern beaches
- Lima: Summer transforms Lima into a sunny, warm, and energetic city. Temperatures range between 24°C and 30°C (75°F–86°F), with bright skies throughout the day—ideal for walking, sightseeing, and enjoying the coastal lifestyle.
- Paracas: Known for its natural reserves and marine life, Paracas experiences dry, sunny weather during summer. Temperatures typically fall between 22°C and 28°C (71°F–82°F), creating the perfect setting for boat tours, wildlife spotting, and desert adventures at the Paracas Reserve.
- Northern Beaches Máncora: This region enjoys the warmest conditions in the country, with temperatures frequently between 28°C and 35°C (82°F–95°F). The sea is at its warmest, making it a top destination for swimming, kitesurfing, and nightlife during these months.
Temperature ranges during summer in Peru
Peru’s summer temperatures vary widely due to its geography:
- Coast:
Warm and sunny, ranging from 24°C to 35°C (75°F–95°F) depending on latitude. Northern beaches are the hottest. - Andes Cusco, Arequipa, Puno:
Days are mild and pleasant, typically between 18°C and 22°C (64°F–72°F), but nights remain cool. Expect afternoon rains due to the wet season. - Amazon Iquitos, Puerto Maldonado:
Hot and humid, with temperatures between 28°C and 34°C (82°F–93°F). Frequent rain showers are common but usually short-lived.
These varying climate zones allow travelers to experience coastal summer heat, Andean rain season, and Amazonian tropical weather all within one trip.
What Is the Weather Like in Peru During Summer?
Summer in Peru brings a unique mix of climates due to the country’s dramatic geography. While the coast becomes hot and sunny, the Andes experience warm days paired with rainy afternoons, and the Amazon remains humid and tropical. These contrasts make summer one of the most diverse seasons to explore Peru, offering everything from beach days to rainforest adventures within a single trip.
Understanding these regional variations is essential for planning, as weather conditions can influence transportation, outdoor activities, and the best times of day to explore each destination.
Climate differences between Coast, Andes, and Amazon
- Coast: The coastal region, stretching from Lima to the northern beaches, enjoys its sunniest and driest weather during summer. Clear skies, warm temperatures, and calm seas make it the ideal season for beach activities, surfing, and city exploration along the Pacific shoreline.
- Andes: In the highlands—particularly Cusco, Arequipa, and Puno—summer coincides with the wet season. Mornings are usually mild and partly sunny, but afternoons often bring rain showers. Temperatures vary significantly between day and night due to altitude.
- Amazon: Summer in the rainforest is hot, humid, and unpredictable, with frequent but brief rainstorms. Despite the rain, wildlife activity increases and rivers rise, creating excellent conditions for jungle excursions and boat trips.
Rainy vs. dry areas in summer
Summer divides Peru into two clear weather patterns:
- Dry Areas: The entire coast experiences minimal rainfall, making it the driest region during these months. Cities like Lima, Paracas, Trujillo, and northern beach towns enjoy stable weather perfect for outdoor activities.
- Rainy Areas: The Andes and the Amazon receive the highest rainfall of the year during summer. In the highlands, rain often falls in the late afternoon or evening, while in the rainforest, storms can occur at any time. Though rain is common, mornings are generally calmer and great for exploration.
These differences highlight why Peru can offer both sunny beach vacations and rainy mountain landscapes simultaneously.
How altitude affects temperature in summer
Altitude plays a major role in Peru’s climate, especially during summer:
- Higher altitudes = colder temperatures:
Cities like Cusco (3,400 m), Puno (3,800 m), and Huaraz (3,000 m) have mild daytime temperatures but chilly nights, even in summer. - Lower altitudes = warmer conditions:
Coastal cities at sea level stay warm both day and night, while the Amazon remains consistently hot due to its tropical lowland climate. - Rapid shifts within short distances:
Travelers can move from sunny beaches to cool highlands in a matter of hours, making layered clothing essential when visiting multiple regions.
Altitude not only influences temperature but also affects how quickly weather can change, especially in the Andes where summer afternoons often bring sudden showers.
Best Places to Visit in Peru During Summer
Summer in Peru opens the door to a wide variety of travel experiences—from sunny beaches and lively coastal cities to cultural highland destinations and adventurous rainforest escapes. Each region offers something unique during these months, making it a perfect season to explore the diversity of the country. Whether you want ocean views, ancient sites, or tropical wildlife, summer provides excellent opportunities for unforgettable experiences.
Top destinations on the coast
Lima: Summer transforms Lima into a warm and vibrant city. With clear skies and pleasant temperatures, it’s the best time to enjoy the capital’s beaches, boardwalks, parks, and world-renowned gastronomy. Miraflores and Barranco become ideal for walking tours, sunsets, and outdoor activities.
Paracas: Known for its natural beauty, Paracas offers perfect summer weather for exploring the Ballestas Islands, the Paracas National Reserve, and the coastal desert landscapes. Calm seas and sunny days make wildlife tours, boat rides, and beach visits especially enjoyable.
Máncora and Northern Beaches: Northern Peru is the country’s top beach destination during summer. Máncora, Vichayito, and Punta Sal boast warm waters, excellent surf conditions, lively nightlife, and a relaxed tropical atmosphere—ideal for travelers seeking both adventure and relaxation under the sun.
Visiting the Andes in summer
Cusco: Although summer is the rainy season in the Andes, Cusco remains a fascinating destination. Mornings are usually clear, providing good conditions to visit Machu Picchu, the Sacred Valley, and historic city sites. Rain typically falls in the afternoon, so early excursions are recommended.
Arequipa: Known as the “White City,” Arequipa enjoys mild weather during summer. While occasional showers may occur, the city’s sunny mornings allow for great views of its volcanic landscape and colonial architecture. Trips to the Colca Canyon remain popular and accessible.
Puno: High-altitude Puno experiences cool weather and seasonal rains in summer, but the Lake Titicaca region is still a captivating experience. Clear mornings are ideal for visiting the Uros floating islands, Taquile, and Amantaní, with afternoons potentially bringing light showers.
Amazon rainforest in summer
Iquitos: Summer brings hot, humid conditions to the Amazon, along with frequent but usually short rainstorms. As river levels rise, travelers can enjoy excellent opportunities for wildlife observation, river cruises, and excursions into lush forest areas.
Puerto Maldonado: Located near the Tambopata National Reserve, Puerto Maldonado offers thriving ecosystems, vibrant wildlife, and warm temperatures during summer. Higher water levels make boat excursions and lake visits especially scenic, while the dense rainforest provides shelter during sudden tropical rains.
The Amazon remains one of the most adventurous regions to visit in summer, offering a truly immersive experience of Peru’s biodiversity.
