About this station
NOAA builds the predictions for Upper Guadalupe Slough from the SAN FRANCISCO (Golden Gate) station: high tides about 1.66× the height, 74 min later; low tides about 1.13× the height, 133 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.
