Where Dumbarton Highway Bridge is
Dumbarton Highway Bridge sits at 37.5067° N, 122.1150° W on San Francisco Bay, at Fremont, CA. The station here is a historical NOAA reference station: a gauge measured the tide at this spot from 1974 until 2011, 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), 5.3 mi away, and high and low water here run on average about 6 min later than there. The nearest weather station is Palo Alto Airport, an airport reporting wind, visibility and sky cover, but no water temperature, 2.8 mi away.
The tide at Dumbarton Highway Bridge
Dumbarton Highway Bridge has a semidiurnal tide: two highs and two lows a day of about the same size, roughly 12 hours 25 minutes apart. This month's predictions average 1.9 high tides a day here. The mean range from lower low to higher high is 8.6 ft, and 6.7 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 1.3 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 Dumbarton Highway Bridge 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.
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 Dumbarton Highway Bridge from the 1983-2001 National Tidal Datum Epoch; mean higher high water is 8.6 ft above it and mean sea level 4.7 ft. These datums are controlled from NOAA's Alameda, CA gauge. Source: NOAA CO-OPS station 9414509, established 1974, gauge removed 2011. The tide times and heights are NOAA's official harmonic predictions for this station; TidalMap republishes them daily and does not alter them.
