What December feels like
December fills every room anyway. The waterfalls run hard, the north-shore surf is at its most serious, and the Lights on Rice parade through Lihue is exactly the kind of small-town Christmas this island does well.
Expect about 7 days with real rain — enough to notice, not enough to plan around. It’s sticky — light fabrics and an afternoon break earn their keep.
Can you swim?
The ocean runs about 80° — bath-warm.
