Season planner for Bonito
Bonito is visitable year-round, but the feel changes with rain and Brazilian holiday calendars. The drier season (roughly May to Sep) usually delivers the clearest rivers and the most comfortable hiking weather, with cooler nights and mild daytime highs. The wetter season (roughly Nov to Mar) is warmer and more humid, with fuller waterfalls and occasional runoff that can reduce visibility on some rivers. Specialty sinkholes can have their own visibility cycles. For example, Lagoa Misteriosa commonly suspends beginner (batismo) dives from mid-Sep to mid-Apr due to microalgae and reduced visibility. Book the most capacity-limited activities first, then fill in flexible days.
