When to go

Best time to visit Bonito

Bonito is visitable yearround, but the feel changes with rain and Brazilian holiday calendars.

Best overall window

May-Sep

Dry season. Best overall water clarity and easier road access. Nights can feel cool (often around 15°C to 18°C), with pleasant daytime highs.

Outside that window

Rainy season. Hotter, more humid days and occasional turbidity after heavy rain. Waterfalls tend to be at their fullest.

Choose your trip style

Start with the overall answer, then switch only when scuba, freedive, snorkel, or topside timing changes the trip in a meaningful way.
