Honolulu is the capital of the state of Hawaii and the seat of Honolulu County, located on the island of Oahu.

Honolulu is the largest city in Hawaii and the major port and economic center of the state.

Honolulu and Honolulu County have the same boundaries and government, and together they are officially known as the City and County of Honolulu. The City and County of Honolulu has jurisdiction over the entire island of Oahu and several small outlying islands, the most remote of which is Kure Atoll, 2,200 km (1,370 mi) West of the city.

Although it technically encompasses all of Oahu, the city of Honolulu is generally considered to be limited to the urban area on the island’s SouthEastern coast. This area extends East to West from Makapuu Point to Pearl Harbor and South to North from the Pacific Ocean to the Koolau Mountains.

The name Honolulu comes from the Hawaiian language and means "sheltered harbor".

The city has a subtropical climate, with an average daily temperature range of 19° to 27°C (66° to 80°F) in January and 23° to 31°C (74° to 88°F) in July. Honolulu averages 560 mm (22 in) of rain per year.
