Hilo Weather in December
United States · early winter in Northern Hemisphere / early summer in Southern Hemisphere
Hilo on the Big Island's rainy east coast is one of America's wettest cities, averaging over 130 inches of rain annually. The northeast trade winds hit Mauna Kea's massive slopes and dump enormous precipitation on the windward coast. The city overlooks Hilo Bay and is vulnerable to tsunamis — markers throughout downtown show previous inundation levels.
Holiday season. Many cities decorate beautifully. Book ahead for December travel.
