About the tides at Upper Guadalupe Slough

Tides here are mixed. On average the two daily highs differ by 1.6 ft, so check which low is the lower one before you head out. 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 today, with a range of 10.8 ft. Neap tides follow tomorrow, when the range shrinks to 6.8 ft.

Upper Guadalupe Slough is a subordinate station, so NOAA publishes only its high and low times and heights. 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.
