The Amazon Rainforest is one of the most biodiverse places on Earth — an immense ecosystem stretching across Brazil, Peru, Colombia, Ecuador, and other South American nations — and picking the best time to visit the Amazon rainforest depends largely on what kind of adventure you want.
Two Main Seasons: Wet and Dry
Unlike temperate regions with four distinct seasons, the Amazon experiences two dominant seasons: the wet season (also called high-water season) and the dry season (low-water season). Temperatures stay warm year-round, so the biggest difference between seasons is rainfall and river levels, which dramatically shape your travel experience.
Wet Season (December to May): During this period, heavy rainfall raises river levels significantly, flooding large portions of the rainforest. The water can rise by several meters, allowing boats and canoes to glide deep into areas that are otherwise inaccessible. This is prime time for water-based exploration, such as river cruises, canoe trips, and seeing wildlife from the waterways.
Dry Season (June to November): As rainfall decreases, river levels recede and forest trails become reachable. This makes exploring on foot much easier, offering better access for hiking, wildlife spotting on land, canopy walks, and trail excursions. Wildlife congregates near limited water sources, increasing chances of sightings.
When to Visit: What to Expect
May to October or June to November is often regarded as the best overall time to visit and have an Amazon Rainforest Tour, especially for first-time travelers. With less rainfall and lower water levels, trails are more accessible, mosquitoes tend to be fewer, and terrestrial wildlife comes out more often. Hiking, canopy tours, and birdwatching are much easier in these months.
For those who prefer boat exploration and flooded jungle scenery, the peak of the wet season can be spectacular. December through May, rivers fill, transforming the forest into a maze of waterways — ideal for river cruises and skiff tours deep into the Amazon’s heart. Wildlife viewing from boats can also be excellent as many creatures descend near treetops over water.
Wildlife and Weather Tips
Every season offers unique wildlife opportunities. In the dry months, animals cluster around shrinking waterholes, making them easier to find on foot or by slow riverboat. During the wet season, you may spot species that are usually hidden, such as pink river dolphins or canopy-dwelling birds, from canoes among flooded trees.
Weather in the Amazon is consistently warm — often between 25°C and 35°C (77°F to 95°F) — but humidity and rainfall vary seasonally. Even in the dry season, occasional showers are common, so packing light rain gear and insect repellent is essential year-round.
Balance Budget, Crowds, and Experience
Travelers on a tighter budget might consider the shoulder months like September or November, when rain is lower but prices and visitor numbers are reduced compared with peak dry-season months. These transitional periods can offer a nice mix of navigable trails and water adventures.
Whether your dream is to trek hidden jungle paths, paddle flooded forests in a canoe, or witness exotic wildlife up close, the Amazon has something spectacular to offer all year.
