About this station
NOAA builds the predictions for Eureka from the HUMBOLDT BAY (North Spit) station: high tides about 1.06× the height, 26 min later; low tides about 1.03× the height, 13 min later.
Mixed semidiurnal tides — two unequal highs and two unequal lows a day — with ranges growing as you head north. Harbor entrances feel the swell as much as the tide.
