With its multitude of cultures and permanently good weather, Hawaii always has something to celebrate. Some of the events to look out for include Hawaii's biggest hula competition, the Merrie Monarch Festival (April); May Day, an extravaganza of lei-making (May); King Kamehameha Day, a state holiday with parades (June); Aloha Festival, a celebration with parades, cultural events, canoe races and Hawaiian music (August to October); the Quicksilver/Eddie Aikau Memorial Big Wave Classic, a surf event held "on O'ahu" when wave heights exceed 6m/20ft (December); and the Ironman Triathlon World Championship on the Big Island (October).
