Kauai experiences a tropical climate with two primary seasons: the dry season (May to October) and the wet season (November to April). However, rainfall can occur year-round, especially in the island’s interior and windward (northeastern) areas. The leeward (southwestern) regions, such as Poipu and Waimea, tend to be drier, offering more consistent conditions for outdoor activities.
