Hilo's rainiest month is November, followed by March and April. Least rainy months are May and June, but remember that showers occur year-round.
Summer tends to be hot and humid, while winter temperatures are balmy and comfortable.
Hilo is booked solid during the Merrie Monarch Festival, which starts on Easter Sunday. If planning to attend the festival, order tickets immediately after December 1 (prior year) and book accommodations up to a year ahead.
During winter high season, accommodations are pricier and often booked solid.
While papayas and bananas are available any time, some tropical fruits are seasonal. Mangoes and lychee, for example, are summer fruits.
