One of the questions we hear most often at Cuyabeno Dolphin Lodge is a simple one: when should I come? The honest answer: there is no single best time to visit Cuyabeno — the reserve is a year-round destination — it sits practically on the Equator, so days are warm and humid in every month, with daytime temperatures usually between 24 and 28 °C. What really changes through the year is not the temperature but the water level, and that is what shapes what you will see and do.
The two faces of Cuyabeno: high water and low water
Cuyabeno is a system of rivers, creeks and lagoons surrounded by igapó — seasonally flooded forest. Instead of four seasons, the reserve lives in a cycle of rising and falling water.
High-water season (roughly March to August)
The rainier months raise the rivers and flood the forest floor. This is when the landscape that made Cuyabeno famous appears: canoes gliding between the trees, mirror-like water in the Laguna Grande, and easy navigation deep into creeks that are unreachable the rest of the year. Rain usually falls in strong, short bursts — often in the afternoon — and clears again.
Low-water season (roughly December to February)
As the water drops, beaches, trunks and muddy banks emerge. Wildlife concentrates around the remaining water, which can make caimans, wading birds and turtles easier to spot along the riverbanks. In particularly dry years the Laguna Grande itself can shrink dramatically, and some canoe routes get shorter — your guide adapts the excursions to where the water is.
So when is the best time to visit Cuyabeno?
- For the classic flooded-forest scenery and canoeing among the trees: March to August.
- For concentrated wildlife along the banks and more exposed trails: December to February.
- For a mix of both worlds: the transition months of September to November.
Whatever the season, the residents that people travel here for — pink river dolphins, monkeys, sloths, macaws, caimans and hundreds of bird species — live in the reserve all year. There is no month in which Cuyabeno “switches off”.
Does the season change the tours?
No — our all-inclusive programs run year-round with the same structure: bilingual naturalist guides, all meals and excursion gear included. What changes is the route of some excursions, which the guides adjust daily to the water level so you always spend your time where the forest is most alive.
