Oahu’s tropical climate makes it a year-round wedding destination, but certain months offer better conditions. The best time for an Oahu destination wedding is during the dry season from April to October, when the weather is sunny with minimal rain. June through August are the hottest months, so couples should consider late afternoon or sunset ceremonies for a cooler experience. The shoulder seasons—April to May and September to October—provide the perfect balance of pleasant weather, fewer tourists, and more affordable rates. December through March is Hawaii’s rainy season, meaning higher chances of showers, especially in lush areas like the North Shore. However, Oahu’s leeward side (like Ko Olina and Waikiki) stays relatively dry year-round. Couples should also consider avoiding peak holiday seasons to secure better prices and availability.
