What April feels like
April is Merrie Monarch week — the hula competition that fills every hotel in Hilo, sells out a year ahead, and turns the whole town into an audience. It is also one of the soggiest weeks you could pick, and nobody has ever once complained.
This is the wet season: rain on about 17 days, so pack accordingly. It’s sticky — light fabrics and an afternoon break earn their keep.
Can you swim?
The ocean runs about 77° — comfortable for swimming.
