What January feels like
January is when the snowbirds and the humpbacks arrive together, and the boats out of Honokohau Harbor book up days ahead. If you want Kealakekua Bay while the water is still glass, be on it before the wind comes up mid-morning.
Real rain shows up about 2 days all month; the rest stay dry.
Can you swim?
The ocean runs about 78° — bath-warm.
