If your goal is to see the Delta at its greenest, full of life and with higher river levels, it’s worth understanding the benefits of the rainy season.

Rainy Season: Intense Beauty and Fewer Tourists

From January to May

Despite the rainfall, this period can also be appealing for travelers seeking a more contemplative experience. Rivers are fuller, mangroves are greener, and tourist flow is lower.

Points to consider:

• Some activities may be limited due to weather conditions

• Tours depend on daily weather conditions

• Higher humidity and heat

According to studies by ICMBio (Chico Mendes Institute for Biodiversity Conservation), the rainy season is essential for maintaining the Delta’s ecological balance, supporting the reproduction of aquatic species and migratory birds.
