Where South San Diego Bay is
South San Diego Bay sits at 32.6291° N, 117.1078° W on the California coast, at Chula Vista, CA, in San Diego County. The station here is a historical NOAA reference station: a gauge measured the tide at this spot from 2017 until 2017, and NOAA still publishes harmonic predictions from that record. There is no live reading here today. The closest gauge measuring live water level is San Diego (Broadway) (NOAA 9410170), 7.2 mi away, and high and low water here run on average about 3 min later than there.
The tide at South San Diego Bay
South San Diego Bay 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 5.9 ft, and 4.2 ft between the average high and the average low, a moderate tide. On an average day the higher high tops the lower high by 0.7 ft and the lower low sits 0.9 ft below the other low. For the water around it: California tides are mixed semidiurnal, two highs and two lows a day of unequal height, with ranges of 4 to 7 ft.
About this station
- High tide reaches South San Diego Bay about 5.1 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 South San Diego Bay from the 1983-2001 National Tidal Datum Epoch; mean higher high water is 5.9 ft above it and mean sea level 3.1 ft. These datums are controlled from NOAA's San Diego, CA gauge. Source: NOAA CO-OPS station 9410135, established 2017, gauge removed 2017. The tide times and heights are NOAA's official harmonic predictions for this station; TidalMap republishes them daily and does not alter them.
