The best time to go to Navirai is during the dry season, from May to September, when the weather is most pleasant for outdoor activities.During these months, you'll experience less rainfall and cooler temperatures, typically ranging from 15°C to 25°C. This makes it ideal for exploring the natural beauty of the region, such as the Parque Nacional da Ilha Grande, which is more accessible and enjoyable without the heavy rains.Families will find this period particularly suitable for trips to local parks and outdoor excursions, as the drier conditions mean fewer mosquitoes and more comfortable days for children to play outside. It's also a good time for those interested in fishing, as the rivers are generally calmer and clearer.For those planning to visit during the wet season, from October to April, be prepared for higher humidity and more frequent, often heavy, rainfall. Temperatures can reach up to 35°C during this time.
