Snow is a rare and fascinating phenomenon in Hawaii due to its tropical climate. The only location where snow occurs regularly is on the summits of the Big Island's Maunakea and Mauna Loa, which stand over 13,000 feet high. These mountains receive snowfall during the winter months when temperatures drop low enough, typically from December to February. The snowpack on these peaks is important as it serves as a vital water source for the island. The resulting snowmelt feeds into rivers and watersheds, providing essential freshwater resources for agriculture and domestic use.

However, it is essential to note that Hawaii's snowpacks are typically shallow and more comparable to a light dusting of snow rather than hefty accumulations found in colder climates. Winter climate characteristics on the summits include freezing temperatures, strong winds, and occasional snowstorms.

Snow science and history in Hawaii are relatively limited due to the rare occurrence of snow. Researchers have focused on studying the impacts of snowmelt on local ecosystems and water resources. Despite its infrequency, the sight of snow-capped mountains in a tropical paradise is certainly a remarkable phenomenon.
