About the tides at Upper Guadalupe Slough

Tides here are mixed. On average the two daily highs differ by 1.5 ft, so check which low is the lower one before you head out. The pattern follows the reference station at San Francisco, San Francisco Bay. The range is large, about 7.3 ft on average. Flats and bars appear and vanish quickly, so keep an eye on the time. That is larger than most California stations on this site. The next spring tides peak tomorrow, with a range of 10.2 ft. Neap tides follow on Friday, when the range shrinks to 4.5 ft. In the next 12 months the highest predicted tide here is 12.0 ft on December 24, and the lowest is −2.1 ft on December 24.

Upper Guadalupe Slough is a subordinate station. NOAA predicts its tides by adjusting San Francisco, San Francisco Bay: highs come about 74 min and lows about 133 min later than there. The nearest other station is Gold Street Bridge, 2 mi away, where high tide comes about 11 min earlier. For tidal currents, see Dumbarton Point, 2.25 miles SE of.

Predictions are based on San Francisco, San Francisco Bay.
