What is the weather in Peru?
Peru weather is extraordinarily diverse due to its varied geography, including the Pacific coast, the Andean highlands, and the Amazon rainforest. This climatic diversity means that multiple weather seasons coexist simultaneously in this country.
However, if you only remember three things about weather conditions in Peru, remember this:
Coast (Lima, Paracas, north coast)
- Desert climate, almost no rain.
- Warm and sunny: roughly from December to March.
- Cool, cloudy, and humid: roughly from June to September (with “garúa,” the coastal mist).
Andes/Highlands (Cusco, Sacred Valley, Lake Titicaca, Arequipa)
- Two clear seasons: dry and rainy.
- Dry season: April to October, sunny days, cold nights, almost no rain (ideal for hiking).
- Rainy season: November to March, greener landscapes, afternoon showers, warmer nights.
Amazon rainforest (Iquitos, Puerto Maldonado, Manu)
- Warm and humid all year.
- More rain from December to May, a bit “drier” from June to November, but you should always expect some rain.
Climate on the Coast of Peru
The Peruvian coast, bathed by the cold currents of the Pacific, has an arid climate all year round, with plenty of sunshine on the north and south coasts and cloudier skies on the central coast. This region, stretching from Tumbes in the north to Tacna in the south, has unique climatic characteristics that make it ideal for a variety of activities and explorations throughout the year.
In the north, cities like Piura and Tumbes experience warm and sunny weather almost all year, with temperatures exceeding 30 °C (86 °F) during the summer (December to March). This area is perfect for those seeking paradisiacal beaches, world-class surfing, and vibrant marine life.
- Summer (December–March): warm to hot days, intense sun, almost no rain.
- Winter (June–September): cooler, very cloudy and humid, with the famous coastal mist called “garúa.”
- Best time for beach holidays: roughly December to March, especially along the north coast.
Lima Peru weather
Peru's capital, Lima, along with other central cities like Trujillo, has a peculiar climate pattern characterized by "garúa,” a fine mist covering the city during winter (June to September), keeping temperatures moderate between 12 °C and 19 °C (54 °F to 66 °F). However, summer brings sunny days and pleasant temperatures ideal for enjoying the beaches and Peru's rich marine gastronomy.
North coast (Piura, Tumbes, Máncora)
- Very warm and sunny for most of the year, with many days above 30 °C (86 °F) in summer.
- Ideal for beaches, surfing, and whale watching (the season depends on the species).
- Rain is more likely during strong El Niño years, when this area can experience heavy downpours.
South coast (Paracas, Ica, Nazca)
Towards the south, the climate becomes more arid, and temperatures moderate. Cities like Ica, and Tacna offer dry weather throughout the year, with warm days and cool nights. This region is renowned for its stunning desert landscapes, vineyards, and rich cultural history.
- Mostly dry, sunny days and cool nights.
- Ideal for sandboarding, visiting vineyards, and spotting coastal wildlife (especially around Paracas).
- Winds often pick up in the afternoon, particularly in the Paracas area.
Weather in the Peruvian Highlands
Ascending into the Andes, the climate dramatically transforms, mainly influenced by altitude and topography. Cusco enjoys sunny days and cold nights throughout the year, making it a paradise for trekking enthusiasts. It offers the globally renowned Inca Trail to Machu Picchu under generally clear skies and a climate that defies its variability.
Dry Season (April to October)
During the dry season, daytime temperatures in the highlands can be pretty pleasant, generally ranging between 12 °C and 24 °C (54 °F and 75 °F). However, nighttime temperatures can drop significantly, especially at higher altitudes, even reaching below zero in some parts of Peru. This wide thermal variation is typical of mountainous areas, where the daytime sun can effectively warm, but the lack of clouds allows heat to dissipate quickly after sunset.
Rainy Season (November to March)
The wet season brings more consistent temperatures but also an increase in rainfall. Daytime temperatures remain in a range similar to the dry season, between 12 °C and 22 °C (54 °F and 72 °F), but nights are usually less cold due to cloud cover, which acts as a thermal insulator. It's ideal for those looking for the most green and vibrant landscapes.
Current climate in Machu Picchu
Machu Picchu, located in Cusco, enjoys a temperate and humid climate. The dry season, from April to October, offers ideal conditions for visiting, with sunny days. From November to March, the rainy season brings frequent but brief rains. Temperatures fluctuate between 10 °C and 25 °C. Due to the high humidity, it's recommended to bring waterproof clothing, sunscreen, and footwear suitable for the weather conditions.

Weather in the Peruvian Jungle
The climate in the Peruvian jungle, especially in the Amazon region, is tropical, humid, and warm throughout the year. This tropical climate is the perfect setting for nature adventures, wildlife spotting, and exploration of native communities, offering a deep immersion into the planet's green lung. This vast and biodiverse area experiences two main seasons determined more by precipitation than by temperatures, which remain relatively constant.
Rainy Season (December to May)
During these months, the jungle receives most of its annual rainfall, which can lead to swollen rivers and more complicated access to some areas. However, it is also a period where flora and fauna are at their most splendid, making it an ideal time if you're looking to experience wildlife in its most vibrant state.
Dry Season (June to November)
Although it's called the "dry" season, rains still occur during these months, but they are much less frequent and of lesser intensity. Many travelers prefer this season, as paths and trails are more accessible, and activities like bird watching and visiting indigenous tribes are facilitated.

Microclimates in Peru
Moreover, Peru boasts several microclimates due to its varied geography. For example, the Sacred Valley of the Incas in Cusco has a more temperate and less rainy climate than Cusco city itself. At the same time, specific areas in the Andes can experience extreme weather conditions, including snow and frost.
Lake Titicaca (Puno)
Days can be sunny and pleasant, but at over 3,800 m (12,467 ft), nights can be very cold, especially in June and July. Good gear is essential.
Arequipa and the Colca Canyon
There are more sunny, dry days here than in Cusco, but nights are still cool. Ultraviolet radiation is strong because of the altitude.
Huaraz and the Cordillera Blanca
Typical high-mountain weather: strong sun, cold nights, and a risk of sudden storms in the high peaks throughout the year.
