Geography and climate
Volcano is located on the east side of the island of Hawaiʻi,[2] on the border of Hawaii Volcanoes National Park and near the northeast rim of Kīlauea's summit caldera.
According to the United States Census Bureau, the CDP has a total area of 58.6 square miles (151.7 km2), all of it land.[3] Hawaii Route 11 passes through the southern part of the community, leading northeast 27 miles (43 km) to Hilo and southwest 37 miles (60 km) to Nāʻālehu.
Its altitude ranges from below 2,800 feet (850 m) in the southeast to over 6,200 feet (1,900 m) at its uninhabited northern end. Due to this, Volcano features a subtropical highland climate (Köppen Cfb), with relatively uniform temperatures and abundant rainfall throughout the year, although rainfall is concentrated during the months of November through April.
