What July feels like
July brings the Fourth over Hilo Bay and a surprising number of visitors on cruise-ship days, when town fills for six hours and then empties again. Much of the rain here falls overnight and in the early hours, which is why mornings often look better than anything you were promised.
This is the wet season: rain on about 19 days, so pack accordingly. It’s sticky — light fabrics and an afternoon break earn their keep.
Can you swim?
The ocean runs about 80° — bath-warm.
