Where Suisun Slough entrance is
Suisun Slough entrance sits at 38.1283° N, 122.0730° W on San Francisco Bay, about 3 mi northeast of Benicia, CA, in Solano County. The station here is a historical NOAA reference station: a gauge measured the tide at this spot from 1977 until 1989, and NOAA still publishes harmonic predictions from that record. There is no live reading here today. The closest gauge measuring live water level is Port Chicago, Suisun Bay (NOAA 9415144), 5.3 mi away, and high and low water here run on average about 13 min later than there. The nearest weather station is Port Chicago, CA, a shore station reporting wind and, at most sites, water temperature, 5.3 mi away.
The tide at Suisun Slough entrance
Suisun Slough entrance 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 5.0 ft, and 3.7 ft between the average high and the average low, a moderate tide. On an average day the higher high tops the lower high by 0.5 ft and the lower low sits 0.7 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 Suisun Slough entrance about 10.1 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: 6.0 ft on Feb 5, 1978.
- Lowest on record: -1.6 ft on Dec 12, 1977.
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 Suisun Slough entrance from the 1983-2001 National Tidal Datum Epoch; mean higher high water is 5.0 ft above it and mean sea level 2.6 ft. These datums are controlled from NOAA's Port Chicago, CA gauge. Source: NOAA CO-OPS station 9415265, established 1977, gauge removed 1989. The tide times and heights are NOAA's official harmonic predictions for this station; TidalMap republishes them daily and does not alter them.
