Where San Mateo Bridge (west end) is
San Mateo Bridge (west end) sits at 37.5800° N, 122.2530° W on San Francisco Bay, at Foster City, CA. The station here is a historical NOAA reference station: a gauge measured the tide at this spot from 1974 until 2005, and NOAA still publishes harmonic predictions from that record. There is no live reading here today. The closest gauge measuring live water level is Redwood City, Wharf 5 (NOAA 9414523), 5.5 mi away, and the tide here runs on nearly the same clock.
The tide at San Mateo Bridge (west end)
San Mateo Bridge (west end) has a mixed tide: two highs and two lows a day, but of unequal size, so one low each day drains noticeably lower than the other. This month's predictions average 1.9 high tides a day here. The mean range from lower low to higher high is 7.7 ft, and 5.9 ft between the average high and the average low, a large tide. On an average day the higher high tops the lower high by 0.6 ft and the lower low sits 1.2 ft below the other low. For the water around it: Bay tides are mixed semidiurnal, two unequal highs a day with a range near 6 ft at the Golden Gate that shifts in time as it moves into the bay and up the rivers.
About this station
- High tide reaches San Mateo Bridge (west end) about 8.3 hours after the moon passes overhead. That lag is local, which is why high water does not line up with the moon.
- Highest water on record: 10.7 ft on Jan 27, 1983.
- Lowest on record: -2.9 ft on Jan 19, 1988.
Datum and source
Heights on this page are feet above mean lower low water (MLLW), the zero NOAA's nautical charts use for soundings. A predicted 0.0 ft low is the average of the lower low each day; a minus tide is water below chart datum, and a 2 ft high means 2 ft more water than the chart shows. NOAA fixes MLLW at San Mateo Bridge (west end) from the 1983-2001 National Tidal Datum Epoch; mean higher high water is 7.7 ft above it and mean sea level 4.1 ft. These datums are controlled from NOAA's Alameda, CA gauge. Source: NOAA CO-OPS station 9414458, established 1974, gauge removed 2005. The tide times and heights are NOAA's official harmonic predictions for this station; TidalMap republishes them daily and does not alter them.
