Where Point Chauncey is
Point Chauncey sits at 37.8917° N, 122.4430° W on San Francisco Bay, at Tiburon, CA. The station here is a subordinate tide prediction point. NOAA has no gauge in the water at this spot; its times and heights are published as offsets from a reference gauge, named below. The closest gauge measuring live water level is Chevron Oil Company Pier, Richmond (NOAA 9414863), 3.4 mi away, and the tide here runs on nearly the same clock.
The tide at Point Chauncey
Point Chauncey 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 5.8 ft, and 4.1 ft between the average high and the average low, a moderate tide. On an average day the higher high tops the lower high by 0.6 ft and the lower low sits 1.1 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 Point Chauncey about 8.0 hours after the moon passes overhead. That lag is local, which is why high water does not line up with the moon.
- NOAA predicts tides here from San Francisco (Golden Gate), station 9414290. High tide comes about 28 min later and low tide about 32 min later than there.
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 Point Chauncey from the 1983-2001 National Tidal Datum Epoch; mean higher high water is 5.8 ft above it and mean sea level 3.1 ft. These datums are controlled from NOAA's San Francisco, CA gauge. Source: NOAA CO-OPS station 9414837, established 1977, gauge removed 1993. The tide times and heights are published as time and height offsets from its reference gauge; TidalMap republishes them daily and does not alter them.
