The best time to visit Itambira Island is during the dry seasons, which run from December to February and again from June to August.During these months, you'll experience less rainfall, making it ideal for enjoying the island's outdoor activities. The lake waters are typically calmer, superb for boat trips and swimming, and the walking trails are easier to navigate. This period is particularly good for those looking to relax by the lake or explore the island's natural beauty without the interruption of heavy showers.For travellers interested in birdwatching, the dry seasons offer excellent opportunities to spot a wide variety of species. The drier conditions mean birds are often more active and visible, making for a rewarding experience. It's also a more comfortable time for guided walks, as the paths are less muddy.While the shoulder seasons (March-May and September-November) can offer some good days and potentially lower prices, there's a higher chance of rain.
