The best time to go to Maliom, New Ireland, is during the dry season, which runs from May to November.
During these months, you'll experience more sunshine and less rainfall, making it ideal for outdoor activities like diving, snorkelling, and exploring the island. The sea conditions are generally calmer, which is superb for boat trips and accessing the more remote dive sites. This period also often coincides with local festivals, offering a chance to experience the island's culture.
For those looking to enjoy the island's natural beauty and water sports without interruption, the dry season offers the most reliable weather.
