Hilo Weather in May
United States · late spring in Northern 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.
One of the most popular travel months worldwide for good reason.
