Wahiawa is located in the Wahiawa District, on the plateau or "central valley" between the two volcanic mountain ranges the Waianae on the west and the Ko'olau's on the east. In Hawaiian, wahi a wa means "place of noise", perhaps a reference to the fact that once upon a time, heavy surf on the distant coast could be heard here. The valley's population was 16,151 according to the 2000 census.
Lakes and reservoirs are rare in Hawaii, and Wahiawa is at once unique in being surrounded on three sides by Lake Wilson (also known as Wahiawa Reservoir or Kaukonahua). The town must be accessed by either of two bridges on Kamehameha Highway (State Rte. 80) across the narrow north and south arms of the reservoir. Outside of the reservoir, the town used to be surrounded by military bases and agricultural fields, but development is making its way up from the increasingly urbanized southern portion of the central plain. Still, there are significant U.S. Army facilities here, including Schofield Barracks, Wheeler Army Airfield, and East Range, an Army training area extending into the hills south and east of town. Schofield Barracks alone is larger than Wahiawa. Wahiawa is also the home of the U.S. Navy's Naval Computer and Telecommunications Area Master Station Pacific.
Mt. Ka'ala the highest peak in Oahu (4,003 ft) is located near Wahiawa in the Waianae Volcanic range. The Wahiawa Reservoir or Lake Wilson is also located in Wahiawa, it is second largest reservoir in Hawaii at (302 acres). It is used to irrigate agricultural fields including the Dole Pineapple Plantation fields which are located at the northern part of Wahiawa. The Wahiawa reservoir also feeds the Anahulu Stream, (also known as Anahulu River), which runs north from the lake all the way towards O‘ahu's North Shore where it empties into the bay at Hale‘iwa.
