About this station
NOAA builds the predictions for Eureka Slough Bridge from the HUMBOLDT BAY (North Spit) station: high tides about 1.08× the height, 33 min later; low tides about the same height, 19 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.
