Climate in the Peruvian Jungle

Portada › Useful information for travel to Peru › Geography & Weather › Climate in the Peruvian Jungle

The extensive Peruvian jungle, crossed by the mighty Amazon River, can be divided into two very distinct areas: the high jungle or cloud forest, located above 700 m a.s.l., and the low jungle, below 700 m a.s.l.
The climate of the Peruvian jungle is hot and humid and remains relatively consistent throughout the year. This climate supports biodiversity and allows for tourism activities throughout most of the year.

Departments of the Peruvian Jungle

The jungle region of Peru is made up of 5 departments: Loreto, Amazonas, San Martín, Ucayali, and Madre de Dios, each with its own characteristic climate.
In the north is Loreto, the largest department, which has a tropical climate and abundant jungle. Amazonas, located near the border with Ecuador, has a warm and rainy climate surrounded by lush forests. San Martín has a warm climate, making it an option for those who prefer this type of weather.

In the central region is Ucayali, which has a warm and very rainy climate, where you can visit numerous waterfalls. In the south is Madre de Dios, where sunsets can sometimes be accompanied by light rain.

Seasons in the Jungle

The seasons are not clearly differentiated; however, they can be identified through rainfall patterns.

  • Summer (December to March): temperatures tend to be warmer, and the days are mostly rainy. During this season, you can enjoy outdoor activities.
  • Winter (June to August): the weather is cooler and temperatures are more moderate, which can make it pleasant to walk around the streets.

There are also 2 transitional seasons:

  • Autumn (April and May): temperatures gradually begin to drop, providing cooler and more comfortable weather after the heat of summer. Rainfall can also occur.
  • Spring (September to November): this season is characterized by receding water levels, which clear the way through the forests, while temperatures gradually begin to rise.

Temperature in the Jungle

The Peruvian jungle is divided into two areas: the high jungle and the low jungle. This means that each area has different temperatures.

In the high jungle, the maximum temperature can reach 26 °C, while the minimum can drop to 12 °C. Between May and August, temperatures can fall to between 8 and 12 °C.

In the low jungle, on the other hand, average temperatures can reach 31 °C and drop to 15 °C.

Humidity in the Peruvian Jungle

Humidity in the high jungle ranges between 80% and 90%, while humidity levels in the low jungle can reach up to 75%. This climate is characterized by abundant rainfall, making the high jungle more humid than the low jungle. In general, humidity in the jungle is very high throughout the year, a key characteristic of the Peruvian jungle climate that influences the visitor experience. Humidity remains constant but intensifies during the rainy season.

Rainfall in the Jungle

The Peruvian Amazon experiences its heaviest rainfall from November to April, when 80% of the region's rainfall is concentrated. The low jungle receives more than 1,000 mm of rain per year. The high jungle receives abundant rainfall, ranging from 2,600 mm to 4,000 mm, with maximum levels exceeding 8,000 mm per year.

Between April and October, rainfall is less frequent, rivers decrease in flow, and roads tend to be more accessible. The rainy season, from November to March, is characterized by frequent showers, sometimes at least one per day, which can cause damage to land access routes.

Cold Surges in the Peruvian Jungle

A cold surge is a weather phenomenon characterized by a sharp drop in temperature accompanied by rain and wind. It is caused by the arrival of cold air masses from the south of the continent between May and August and mainly affects Madre de Dios, Ucayali, Huánuco, San Martín, and Loreto. Therefore, during this period, it is recommended to wear warm, waterproof clothing that protects your head, face, and ears.

Climate in the Main Cities of the Jungle

Climate in Iquitos

Throughout the year, the climate is tropical, warm, and very humid. Temperatures usually reach around 32 °C and can drop to 22 °C at night. There is not much difference between summer and winter, but there are normally days with high humidity, when the heat feels even more intense, resulting in greater rainfall.
Therefore, the city can be described as having a warm and humid climate, with abundant rainfall and two clearly differentiated seasons according to the water levels of its rivers.

Climate in Tarapoto

It is a place where it is hot throughout the year due to its location and surrounding vegetation, with an average temperature of 27 °C. The climate is divided into two seasons: the first is summer, characterized by less rainfall during July, August, and September. Temperatures can reach 34 °C, and the perceived temperature is likely to be even higher. During these months, due to the lower amount of rainfall, river levels decrease and the water becomes much clearer.

During winter, Tarapoto does not usually experience very low temperatures. Rainfall is frequent between January and April, which can be quite inconvenient for residents because even when it rains for only a few minutes, a significant amount of water can accumulate in the streets. On some days, the rain can continue throughout the day. This can occur when the rain is light and the raindrops are smaller than usual. Temperatures during this season are usually around 24 °C.

Climate in Puerto Maldonado

Puerto Maldonado has a tropical, warm, and humid climate. Rainfall is scarce between June and August, while the rainy season extends from December to March.
Temperatures throughout the year range from 18 °C to 32 °C and rarely fall below 13 °C or exceed 36 °C. The best time to visit Puerto Maldonado is from late May to early September.

Climate in Pucallpa

Pucallpa is a warm, humid, and moderately rainy city. Minimum temperatures reach 22 °C and maximum temperatures reach 33 °C, so it is recommended to wear lightweight clothing, stay well hydrated, use sunscreen, and carry a lightweight rain jacket.
In general, Pucallpa tends to feel hot and muggy, with frequent rainfall at different times of the year.

Best Time to Visit the Peruvian Jungle

Throughout the year, the climate in the Peruvian jungle is generally stable and offers favorable conditions for tourism year-round, although very rainy days may occur.

What Should I Bring to the Peruvian Jungle?

When visiting the Peruvian jungle, it is essential to bring suitable clothing to adapt to the varied climate. Here are some suggestions:

  • Lightweight and breathable clothing: for warm days, lightweight long-sleeved shirts are recommended so they can dry more quickly in case of rain.
  • Sunscreen and a hat: protect your skin from the sun with broad-spectrum sunscreen and a wide-brimmed hat.
  • Mosquito repellent: repellent is essential during your visit to the jungle. Mosquitoes are common in the jungle, so it is advisable to bring repellent.
  • Lightweight layers: even in the jungle, nights can be cool, so bring a lightweight jacket for colder evenings.
  • Comfortable footwear: choose hiking footwear, especially if you plan to explore the jungle.
