The best time to visit Bonito is during the dry season, which runs from May to September, for ideal weather conditions and clearer waters.The dry season offers consistently sunny days with less humidity, making outdoor activities more pleasant. The lack of rain also means the rivers and natural pools are at their clearest, which is particularly appealing for snorkelling and diving in spots like the Rio da Prata.For couples seeking a relaxing yet active holiday, this period is perfect. You'll find the natural beauty of the region, such as the Gruta do Lago Azul, is best experienced under clear skies. Plus, the comfortable temperatures are ideal for exploring the numerous waterfalls without the discomfort of high humidity.Families travelling with children will also appreciate the dry season.
