The "coffee belt" in Kona is approximately two miles wide from 700 feet (210 m) to 2,000 feet (610 m) elevation. Other districts where coffee is grown include Kaʻū to the far south, Puna in the southeast, and Hāmākua to the northeast.
Although coffee can be harvested year-round in Kona, highest production begins in late summer and extends to early spring. In 2008–2009 seasons, there were about 790 farms on the island, and 40 on other islands. Average yield was equivalent to 1400 pounds of parchment per acre. A total of about 7,800 acres (3,200 ha) are planted with coffee throughout the state. A little over half the acreage are outside the Big Island, in particularly large on the island of Kauai, indicating that farms on other islands are larger in average size compared to those in Kona. Although total production increased from 2007 to about 8.6 million pounds, farm prices actually dropped, so the dollar value decreased by about 8% (Due to the relatively few farms in Kauai, Maui and Honolulu counties their numbers are combined in USDA statistics to avoid disclosure of individual operations in those counties.) Several former sugarcane and pineapple plantations have changed to 100% pure Kona Coffee production.
