About the tides at Smith Slough

Smith Slough has a mixed tide. The two daily highs, and especially the two lows, can differ a lot in height. The pattern follows the reference station at San Francisco, San Francisco Bay. With a mean range of about 6.0 ft, the shoreline here changes a lot between high and low water. That is larger than most California stations on this site. Looking a year ahead, predictions peak at 9.3 ft on December 24 and bottom out at −1.8 ft on December 24.

Tides here are worked out from the reference station at San Francisco, San Francisco Bay, with NOAA time and height corrections. Times are good for planning, but local wind can shift them. The nearest other station is Redwood City, 0.7 mi away, where high tide comes about 28 min earlier. For tidal currents, see Redwood Creek.

Predictions are based on San Francisco, San Francisco Bay.
