About this station

NOAA builds the predictions for Elk River Railroad Bridge from the HUMBOLDT BAY (North Spit) station: high tides about 0.71× the height, 19 min later; low tides about 0.31× the height, 92 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.
