Volcano national parks have limited coverage

Best time to visit Hawaii from Australia

Hawaii has warm weather year-round with temperatures ranging from 24 to 32 degrees. The dry season from April to October is the best time to visit with lower humidity and calmer seas. Summer from June to August is peak season with the busiest beaches and highest hotel rates. Shoulder season from April to May and September to October offers good weather with fewer crowds and lower prices. The winter season from November to March brings more rain and larger surf on the North Shore of Oahu, which draws surfers for the famous Triple Crown of Surfing. Humpback whales visit Hawaiian waters from December to April. Australian school holidays from December to January coincide with Hawaii's busy winter whale-watching season.
