The best time to go to Retro is during the dry season, which runs from May to October, as this period offers pleasant weather and ideal conditions for exploring.During these months, you can expect clear skies, lower humidity, and average temperatures ranging from 18°C to 25°C. This makes it great for enjoying Retro's outdoor attractions, such as the pristine beaches and the Retro Rainforest National Park, without the heavy rainfall or intense heat and humidity of the wet season. It's also generally the best time for activities like snorkelling or diving at the Retro Reef, as visibility is typically at its best.For those looking to avoid crowds and potentially find better value on accommodation, the shoulder months of May, early June, and October are excellent choices. The weather is still very good, but the peak holiday rush hasn't quite begun or has already ended, offering a more relaxed experience.However, if your primary interest is experiencing the lushness of the rainforest and witnessing dramatic waterfalls at their fullest, the wet season (November to April) can be an option, though you should be prepared for higher humidity, more rain, and occasional storms.
