How the Amazon divides the year
Unlike southern Brazil, the Amazon does not have seasons defined by temperature. Here, the seasons are determined by river levels: the wet season, when waters rise and flood the forest, and the dry season, when rivers recede and reveal beaches, trails, and the forest floor. On the Rio Negro, the most intense flooding generally occurs between March and July, and the most pronounced dry period runs from August to November, with waters reaching their lowest levels in October and November.
This variation can represent a difference of up to 10 to 12 meters in river level, which radically transforms the landscape, access to certain habitats, and the experiences available to those navigating. It is not a question of which season is better: it is a question of which experience you want to live.
The Amazon of the wet season: navigating inside the forest
During the wet season, rivers rise and flood vast areas of the forest, creating the igapo, the flooded woodland, and the igarapes, channels that form between submerged trees. It is one of the most extraordinary landscapes in the Amazon: the canoe navigates between treetops that emerge only at their tips, river dolphins appear in the lakes formed by the flooding, birds discover new habitats, and the forest seems to have transformed into an ocean.
For those who want canoe excursions between the trees, birdwatching in flooded areas, and an Amazon unlike any image they have previously seen, the wet season is the ideal period. The Anavilhanas Archipelago, one of the Untamed Amazon destinations, is especially remarkable at this time: the 400 islands that make up the archipelago are partially submerged, creating channels and passages that only exist during the flood.
The Amazon of the dry season: beaches, treks, and open forest
In the dry season, rivers recede and reveal what was hidden. White-sand beaches emerge along the banks of the Rio Negro and the Tapajos, trails become accessible, and the forest floor can be navigated on foot. It is the season of beach bonfires, river swimming with a visible bottom, and treks that penetrate deep into the forest.
For birdwatchers, the dry season offers greater visibility: without the water canopy covering part of the igapo, birds concentrate more along the riverbanks and are easier to observe. For families with children, the dry season offers a different rhythm: more activities on land, more contact with the forest floor, more freedom of movement off the boat.
The Untamed Amazon operates in both seasons
The Untamed Amazon cruise schedule covers both periods, and each itinerary is adapted to what the Amazon offers at each time of year. During the wet season, activities prioritize the igarapes, canoe excursions, and observation of dolphins and birds in the flooded forest. In the dry season, beaches, treks, and bonfires take more prominent roles in the itinerary.
There is no wrong choice. There is the right choice for what you want to experience. The 2027 cruises cover both periods, with departures throughout the year. This is the moment to check the dates and choose which Amazon you want to discover.
