Kailua beach in Hawaii

Kailua is a census-designated place (CDP) located in the City & County of Honolulu, Hawaii, United States. It lies in the Koʻolaupoko District of Oʻahu on the windward coast at Kailua Bay. It is in the judicial district and the ahupua'a named Ko'olaupoko. It is 12 miles (19 km) northeast of Honolulu - over Nu'uanu Pali, the tallest mountain peak in the Ko'olau mountain range.
In the Hawaiian language Kailua means "two seas," or "two currents," a contraction of the words kai (meaning sea or sea water) and ʻelua (meaning two); it is so named because of the two lagoons in the district or the two currents which run through Kailua Bay.

Kailua is primarily a residential community, with a centralized commercial district along Kailua Road. It has a compact, easy-to-shop business district surrounded by mostly single-family homes. By 1992 50,000 residents encompassed a central urban core with surrounding residential areas.

Places of note in Kailua include Kailua Beach Park (photo at right), Lanikai Beach, Kawai Nui Marsh, and Marine Corps Base Hawaiʻi.

Beach
Kailua Beach has been repeatedly ranked among the best beaches worldwide. It was ranked as #1 U.S. beach in 1998 by coastal expert Dr. Stephen Leatherman, and then "retired" from subsequent consideration.
It is a crescent-shaped, about 2 miles (3.2 km) in length and 50-150 feet wide. The ocean bottom fronting the beach slopes gently to overhead depths without any coral heads. Light to medium waves support surfing and body surfing.
The steady trade winds make Kailua Beach one of the world’s preeminent windsurfing and kite boarding destinations. Robbie Naish, regarded by most observers as the windsurfing's greatest champion, grew up at Kailua Beach.
