About this station
NOAA builds the predictions for Arcata Wharf from the HUMBOLDT BAY (North Spit) station: high tides adjusted +0.1 ft, 48 min later; low tides adjusted +0.1 ft, 54 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.
