About the tides at Alameda

This is a mixed-tide station. Some days bring a deep low and a shallow low, and a few days have only one of each. The average range is about 4.8 ft. Spring tides add a little more at both ends. From the average lower low to the average higher high, the difference is 6.6 ft. The next spring tides peak on October 28, with a range of 8.5 ft. Neap tides follow today, when the range shrinks to 1.8 ft. In the next 12 months the highest predicted tide here is 7.9 ft on December 24, and the lowest is −1.9 ft on December 24.

San Francisco Bay is a NOAA water level station with a live gauge, updated every 6 minutes. Predictions come from the station's own tide records. It also reports water temperature, wind and air pressure. It was established in 1939. The nearest other station is Alameda Naval Air Station, 2 mi away.
