Amazon Rainforest Weather

Amazon rainforest weather is characterized by a lot of rain annually, which allows for much of the green plant life and the diverse wildlife in the rainforest to thrive. The bio-diverse rainforest is spread out between four countries which are Brazil, Ecuador, Bolivia and Peru.

The countries that host the Amazon rainforest in South America offer a unique perspective of this incredibly vast tropical rainforest. In addition, the weather conditions open up different ways to explore the Amazon jungle.

What Is the Weather Like in the Amazon Rainforest?

The weather in the Amazon rainforest features a tropical climate, also known as a humid climate. In tropical rainforests, the rain falls all year round, with rainfall levels and daytime temperatures changing according to the seasons.

There are two main seasons in the Amazon rainforest:

The dry season or low water season occurs from June through to December in the Amazon forest. The dry seasons in the Amazon have less rain which lets the waters recede in the flooded forest. The receding waters clear up walking trails in the forest, making it easier to explore land animal species such as nesting birds on the beaches.

The wet season in the Amazonian rainforest is characterized by more rain and occurs from December through to May. The river levels rise in the Amazon to at least 23 ft (7 m) higher, which opens up waterways that allow access to canoes. The high rivers allow for a closer view of creatures that live in the tall canopy trees, such as howler monkeys.

The Amazonian forest has a humid season with humidity levels ranging between an average of 77% in the lower rainy seasons to 88% in the higher rainy season. As a result, the average temperature in this vast forest ranges between 77°F (25°C) to 86°F (30°C).

Brazil’s Amazon Weather

Brazil’s Amazon weather is often rainy, from halfway through December to halfway through May. During this high water season, heavy winds result in heavy rainfall around the central Amazon. This central Amazon region features the Black River (Rio Negro), which is the largest black river in the world situated in Manaus.

The lower water seasons run from June to December in the Brazilian Amazon. The average temperatures range between 85°F to 95°F (29°C to 35°C) during the day with temperatures cooling down as low as 75°F (23°C) at night.

Peru’s Amazon Weather

Peru’s Amazon weather features microclimates in some areas of the jungle, with rain showers and sunshine in different parts of the jungle at the same time. The Peruvian Amazon has two distinct ecoregions separating it, which are the “Down Forest” (Selva Baja) and the “High Forest” (Selva Ata).

The Down Forest in the Amazon has a warm climate with temperatures that average at 82ºF (28ºC) and humidity levels of up to 75%. The High Forest is situated at higher altitudes along the eastern slopes of the Andes, ranging between 1300 ft and 3300 ft (400m and 1000m) in elevation. This elevated region experiences slightly cooler temperatures than the Down Forest.

The Amazon rainforest in Peru experiences the most precipitation from November through to April, with 80% of the region’s rainfall occurring during this period. The temperatures during the wetter season are relatively low and range between 62°F (17°C) to 90°F (32°C), dropping to as low as 45°F (7°C) on some occasions.

Ecuador’s Amazon Weather

The Ecuadorian Amazon weather has its driest months from January through to March, while the rainy season occurs from March through to July. The rainfall in the Andes spills over into the Amazon Basin in Ecuador, resulting in the rising water levels of the Napo River, which flows through Peru to reach the Amazon River. The temperatures average between 85°F to 95°F (29°C to 35°C).

Bolivia’s Amazon Weather

Bolivia’s Amazon weather is unpredictably volatile. The Bolivian Amazon has a microclimate with simultaneously heavy rains and sunny days. An occasional torrential downpour is also common during the drier seasons. The average temperatures range between at least 62°F (17°C) to 90°F (32°C).

Activities to Enjoy in the Amazon Rainforest

The wet and dry seasons of the Amazon rainforest allow for different activities. Rainforest lodges offer incredible tours, such as night canoe trips. These night-time trips provide an opportunity to discover nocturnal animals and other species. The large forest cover has much to explore at any time of the year.
