The best time to visit Borba is during the dry season, which typically runs from June to October.
During these months, the weather is more predictable with less rainfall, making it ideal for exploring the natural beauty of the region. The river levels are lower, revealing more of the riverbanks and making boat trips and wildlife spotting more comfortable and accessible. This is superb for travellers keen on outdoor activities and experiencing the Amazon's unique ecosystems.
The shoulder months of May and November can also be good, offering a transition between seasons with fewer crowds and still pleasant weather, though there might be a slightly higher chance of rain.
