The best time to go to Oneroa is during the dry season, which runs from April to November, offering consistently pleasant weather for all activities.
This period avoids the higher humidity and rainfall of the wet season, ensuring ideal conditions for enjoying the island's outdoor attractions. You'll find plenty of sunshine and comfortable temperatures, great for relaxing on the beaches or exploring the island.
For couples looking for a romantic getaway, the shoulder months of April, May, October, and November are particularly appealing. During these times, the weather is still excellent, but there are generally fewer crowds than in the peak months of July and August, allowing for a more intimate and tranquil experience.
Families travelling with children will find the peak dry season months of June, July, and August ideal. The consistent good weather means you can reliably plan beach days, snorkelling trips, and other family-friendly excursions without worrying about disruptions from rain.
