Kohala is the name of the northwest portion of the island of Hawaiʻi in the Hawaiian Archipelago. In ancient Hawaii it was often ruled by an independent High Chief called the Aliʻi Nui. In modern times it is divided into two districts of Hawaii County: North Kohala and South Kohala. Locals commonly use the name Kohala to refer to the census-designated places of Halaʻula, Hāwī, and Kapaʻau collectively. The dry western shore is commonly known as the Kohala Coast, which has golf courses and seaside resorts.
The area was named after the dominating geological feature Kohala Mountain, the oldest of Hawaiʻi Island's five major volcanic mountains. The current districts cover the north and western sides of the mountain, 20°7′55″N 155°47′38″W / 20.13194°N 155.79389°W / 20.13194; -155.79389Coordinates: 20°7′55″N 155°47′38″W / 20.13194°N 155.79389°W / 20.13194; -155.79389. It was one of the five ancient divisions of the island called moku.
The natural habitats in Kohala range across a wide rainfall gradient in a very short distance - from less than 5 inches (130 mm) a year on the coast near Kawaihae to more than 150 inches (3,800 mm) year near the summit of Kohala Mountain, a distance of just 11 miles (18 km). Near the coast are remnants of dry forests, and near the summit is a cloud forest, a type of rainforest that obtains some of its moisture from "cloud drip" in addition to precipitation.
