Geography/Environment
Oʻahu is the third largest Hawaiian Island. The volcanic island’s shoreline is 227 miles / 365 kilometers long. The island is comprised of the Waiʻanae and Koʻolau volcanoes with a saddle (valley) between them. Honolulu, the state capital, is located on its southeast coast.
Activities
Ocean adventures including snorkeling, diving, cruises, parasailing, and surfing are plentiful on O'ahu. Play golf at a world renowned course. Spend an afternoon at Pearl Harbor. Go on an eco-cultural excursion. Attend a luau. There are many activities to enjoy on this island.
Climate and Weather
Although Hawaii's busiest tourist season is during winter (December to February), this has more to do with the weather elsewhere, since many visitors are snowbirds escaping cold winters back home. You don't find much nicer weather anywhere in the world. Near the coasts, which you almost always are, average highs are a pleasant 80ºF (27ºC), and the difference between summer and winter temperatures is only 10ºF. The rainiest period is between December and March. It also matters on which side of the islands you are. In general, the driest, sunniest conditions and the calmest waters are on the southwestern side of the islands. The northeastern side of the islands receives decent rainfalls.
