What Will Big Island Weather Be Like In March?
On the sunny west side of the Big Island, the weather is remarkably consistent year-round with highs in the 80s and lows in the 60s and 70s. The record high temperature in Kailua-Kona was 95 degrees in 1989 and the lowest recorded temperature was 57 degrees in 2003. The Kona Coast receives just 11 inches of rain per year, so vacationers staying in Kona are virtually assured of warm, sunny days.
At higher elevations on Hawaii’s Big Island, the weather is cooler. Waimea has daytime highs in the 60s to low 70s, while the temperature at Hawaii Volcanoes National Park is usually around 60 degrees. The mountain peaks of Mauna Kea and Mauna Loa are generally about 30 degrees colder than the coastal temperatures, so be sure to bring warm clothes if you’ll be visiting the mountains.
Vacationers can enjoy swimming and water sports year-round since the ocean temperature ranges from 71 to 81 degrees. Hawaii’s hurricane season runs from June to November, but hurricanes are fairly infrequent. The last major hurricane to hit Hawaii’s Big Island was Estelle in July of 1986.
