The best time to visit Raiatea is during the dry season, which runs from May to October, offering the most pleasant weather for exploring the island.During these months, you'll experience less humidity and more sunshine, with average temperatures around 27°C (81°F). This period is ideal for all outdoor activities, including snorkelling, diving, sailing, and hiking. The calmer seas also make inter-island travel smoother.For those looking to avoid larger crowds and potentially find slightly better value on flights and accommodation, the shoulder months of May, June, September, and October are particularly good. You'll still enjoy excellent weather but with fewer visitors than during the peak months of July and August.The wet season, from November to April, sees higher humidity, more frequent rainfall, and a greater chance of tropical storms.
