The best time to go to Helvecia is during the dry season, which runs from April to October.
During these months, the weather is generally cooler and less humid, with less rainfall, making it ideal for outdoor activities and exploring the region. The average temperatures range from 15°C to 25°C, providing comfortable conditions for fishing, birdwatching, and enjoying the natural beauty of the Paraná River and its tributaries. This period also sees fewer mosquitoes, which can be a consideration during the warmer, wetter months.
For those interested in fishing, particularly for species like dorado and surubí, the dry season offers excellent opportunities as water levels are typically lower and fish are more concentrated in the main channels. This makes for a more predictable and often more successful fishing experience.
Travellers looking for a relaxed and pleasant experience will find the dry season particularly appealing.
