Oahu ( // ) (Hawaiian: Oʻahu (pronounced [oˈʔɐhu] )), also known as "The Gathering Place", is the third-largest of the Hawaiian Islands. It is home to roughly one million people—about two-thirds of the population of the U.S. state of Hawaii. The island lies within Honolulu County and the state capital, Honolulu, is on Oahu's southeast coast.
Including small associated islands such as Ford Island plus those in Kāneʻohe Bay and off the eastern (windward) coast, its area is 596.7 square miles (1,545.4 km2), making it the 20th-largest island in the United States.
Oahu is 44 miles (71 km) long and 30 miles (48 km) across. Its shoreline is 227 miles (365 km) long. The island is composed of two separate shield volcanoes: the Waiʻanae and Koʻolau Ranges, with a broad valley or saddle (the central Oahu Plain) between them. The highest point is Kaʻala in the Waiʻanae Range, rising to 4,003 feet (1,220 m) above sea level.
The island was home to 953,207 people in 2010 (approximately 72% of the population of the state, with approximately 81% of those living in or near the Honolulu urban area). Oahu has for a long time been known as the "Gathering Place". The term Oʻahu has no confirmed meaning in Hawaiʻian, other than that of the place itself. Hawaiʻiloa , the Polynesian navigator credited with discovery of the Hawaiian Islands. The story relates that he named the island after his daughter.Ancient Hawaiian tradition attributes the name's origin in the legend of
Residents of Oahu refer to themselves as "locals" (as done throughout Hawaii), no matter their ancestry.
The city of Honolulu—largest city, state capital, and main deepwater marine port for the State of Hawaiʻi—is located here. As a jurisdictional unit, the entire island of Oahu is in the Honolulu County, although as a place name, Honolulu occupies only a portion of the southeast end of the island.
Well-known features found on Oahu include Waikiki, Pearl Harbor, Diamond Head, Hanauma, Kāneʻohe Bay, Kailua Bay, North Shore.
While the entire island is officially the City and County of Honolulu, locals identify settlements using town names (generally those of the census-designated places), and consider the island to be divided into various areas, which may overlap. The most commonly accepted areas are the "City", "Town" or "Town side", which is the urbanized area from Halawa to the area below Diamond Head (residents of the island north of the Koʻolau Mountains consider the Town Side to be the entire southern half), "West Oahu", which goes from Pearl Harbor to Kapolei, ʻEwa and may include the Mākaha and Waiʻanae areas; the "North Shore" (northwestern coast); the "Windward Side" (northeastern coast from Kahuku to Kāneʻohe); the "East Side" or "East Coast" (the eastern portion of the island, from Kāneʻohe on the northeast, around the tip of the island to include much of the area east of Diamond Head); and "The Valley" or "Central Oahu" which runs northwest from Pearl Harbor toward Haleʻiwa. These terms are somewhat flexible, depending on the area in which the user lives, and are used in a mostly general way, but residents of each area identify strongly with their part of the island, especially those outside of widely-known towns. For instance, if locals are asked where they live, they would usually reply "Windward Oahu" rather than "Laie".
Being roughly diamond-shaped, surrounded by ocean and divided by mountain ranges, directions on Oahu are not generally described with the compass directions found throughout the world. Locals instead use directions originally using Honolulu as the central point. To go ʻewa means traveling toward the western tip of the island, "Diamond Head" is toward the eastern tip, mauka is inland (toward the central Koʻolau Mountain range, north of Honolulu) and makai toward the sea. When these directions became common, Diamond Head was the eastern edge of the primary populated area. Today, with a much larger populace and extensive development, the mountain itself is often not actually to the east when directions are given, and is not to be used as a literal point of reference—to go "Diamond Head" is to go to the east from anywhere on the island.
Oahu is also known for having the longest rain shower in history, which lasted for 200 consecutive days. Kāneʻohe Ranch reported 247 straight days with rain from August 27, 1993 to April 30, 1994. The island has many nicknames one of them being "rainbow state." This is because rainbows are a common sight in Hawaiʻi due to the frequent rain showers. The average temperature in Oahu is around 70–85 °F (21–29 °C) and the island is the warmest in June through October. The weather during the winter is cooler, but still warm with an average temperature of 68–78 °F (20–26 °C).
The windward side is known for some of the most beautiful beaches in the world. Lanikai Beach on the windward coast of Oahu has been consistently ranked among the best beaches in the world.

The island has been inhabited since at least 3rd century A.D.The 304-year-old Kingdom of Oʻahu was once ruled by the most ancient aliʻi in all of the Hawaiian Islands. The first great king of Oʻahu was Maʻilikūkahi, the lawmaker, who was followed by many generation of monarchs. Kualiʻi was the first of the warlike kings and so were his sons. In 1773, the throne fell upon Kahahana, the son of Elani of Ewa. In 1783, Kahekili II, King of Maui, conquered Oʻahu and deposed the reigning family and then made his son, Kalanikūpule, king of O'ahu, turning O'ahu into a puppet state. Kamehameha the Great would conquer in the mountain Kalanikūpule's force in the Battle of Nuʻuanu. Kamehameha founded the Kingdom of Hawaiʻi with the conquest of Oʻahu in 1795. Hawaiʻi would not be unified until the islands of Kauaʻi and Niʻihau surrendered under King Kaumualiʻi in 1810. Kamehameha III moved his capital from Lāhainā, Maui to Honolulu, Oʻahu in 1845. ʻIolani Palace, built later by other members of the royal family, is still standing, and is the only royal palace on American soil.
Oahu was apparently the first of the Hawaiian Islands sighted by the crew of HMS Resolution on January 19, 1778, during Captain James Cook's third Pacific expedition. Escorted by HMS Discovery, the expedition was surprised to find high islands this far north in the central Pacific. Oahu was not actually visited by Europeans until February 28, 1779, when Captain Charles Clerke aboard HMS Resolution stepped ashore at Waimea Bay. Clerke had taken command of the ship after James Cook was killed at Kealakekua Bay (island of Hawaiʻi) on February 14, and was leaving the islands for the North Pacific. With the discovery of the Hawaiian Islands came the introduction of disease, mosquitoes, and aggressive foreign animals. Although indirect, the simple exposure to these foreign species caused permanent damage to the Native Hawaiian people and environment.
The Imperial Japanese Navy's attack on Pearl Harbor, Oahu on the morning of December 7, 1941 brought the United States into World War II. The surprise attack was aimed at destroying the American will to fight and make them sue for peace immediately by attacking the Pacific Fleet of the United States Navy and its defending Army Air Forces and Marine Air Forces. The attack damaged or destroyed twelve American warships, destroyed 188 aircraft, and resulted in the deaths of 2,335 American servicemen and 68 civilians (of those, 1,177 were the result of the destruction of the USS Arizona alone).
Today, Oahu has become a tourism and shopping haven. Over five million visitors (mainly from the contiguous United States and Japan) flock there every year to enjoy the island.
Oahu boasts of having had the Olympic Gold Medal winner Duke Kahanamoku serve as Sheriff, perhaps the only such athlete to serve as a law enforcement professional. He held that office for 13 consecutive terms, from 1932 until 1961.
Visitors should be aware that some of the police vehicles on Oahu (and on the "Big Island" of Hawaiʻi) are unmarked except for the blue lights mounted on their roofs.
Beginning with a contract with the US Navy in 2001, Ocean Power Technologies began ocean-testing Azura, its wave power generation system at the Marine Corps Base Hawaii (MCBH) at Kāneʻohe Bay. The Oahu system was launched under the company's program with the US Navy for ocean testing and demonstration of such systems, including connection to the Oahu grid. kW, a system with 500 kW to 1 MW is planned to be installed at end of 2017.The prototype can produce 20
Oahu has 343 MW of rooftop solar power,and potential for 92 MW of wind power.

In the Hawaiian language, kāne ʻohe means "bamboo man". According to an ancient Hawaiian story a local woman compared her husband's cruelty to the sharp edge of cutting bamboo; thus the place was named Kāneʻohe or "Bamboo man". The population was 34,597 at the 2010 census. Kāneʻohe is the largest of several communities along Kāneʻohe Bay and one of the two largest residential communities on the windward side of Oʻahu. The commercial center of the town is spread mostly along Kamehameha Highway.

Ka'ala in the Wai’anae Mountain Range. It is the last of the leeward towns on O'ahu. North of Mākaha is little development, i.e. no towns, no gas stations, or restaurants. The population of Mākaha was 8,278 at the 2010 census. It is located 35 miles northwest of Honolulu, but is a part of Honolulu County.
Waimea Bay is located in Haleiwa on the North Shore of O'ahu in the Hawaiian Islands at the mouth of the Waimea River. Waimea Valley extends behind Waimea Bay. Waimea means "reddish water" in Hawaiian.

It had a population of 778 at the 2010 census. In Hawaiian, koʻolau poko means "short windward", referring to the fact that this is the shorter of the two windward districts on the island. Koʻolaupoko extends from Makapuʻu Point on the southeast to Kaʻōʻio Point on the north. Included within the district, south of North Koʻolaupoko, are the largest windward towns of Kāneʻohe, Kailua, and Waimānalo.
Diamond Head is a volcanic tuff cone on the Hawaiian island of Oʻahu and known to Hawaiians as Lēʻahi. The Hawaiian name is most likely derived from lae plus ʻahi (tuna) because the shape of the ridgeline resembles the shape of a tuna's dorsal fin. Its English name was given by British sailors in the 19th century, who mistook calcite crystals on the adjacent beach for diamonds.

The Honolulu Volcanics are a group of volcanoes which form a volcanic field on the island of Oahu, Hawaii, more specifically in that island's southeastern sector and in the city of Honolulu from Pearl Harbor to the Mokapu Peninsula. It is part of the rejuvenated stage of Hawaiian volcanic activity, which occurred after the main stage of volcanic activity that on Oahu built the Koʻolau volcano. These volcanoes formed through dominantly explosive eruptions and gave rise to cinder cones, lava flows, tuff cones and volcanic islands. Among these are well known landmarks such as Diamond Head and Punchbowl Crater.
