About this station
NOAA builds the predictions for Napoopoo, Kealakekua Bay from the HILO station: high tides about 0.80× the height, 48 min later; low tides about 0.67× the height, 47 min later.
Trade-wind shores with small mixed tides — a foot or two in Hawaii, a few feet in the Caribbean — where swell and season matter more than range.
