The best time to go to Niuafo'Ou is during the dry season, which runs from May to October.
During these months, you'll experience lower humidity and less rainfall, making it ideal for enjoying the island's natural beauty and outdoor activities. The weather is generally sunny with pleasant temperatures, great for exploring the volcanic landscapes or relaxing by the crater lake, known as Vai Lahi.
For travellers interested in wildlife, particularly birdwatching, the dry season offers excellent opportunities to spot the unique Niuafo'ou megapode.
