The closest gauge measuring live water level is Chevron Oil Company Pier, Richmond (NOAA 9414863), 23.7 mi away, and high and low water here run on average about 124 min later than there. The nearest weather station is Petaluma Municipal Airport, an airport reporting wind, visibility and sky cover, but no water temperature, 2.1 mi away.
The tide at Upper drawbridge, Petaluma River
Upper drawbridge, Petaluma River has a semidiurnal tide: two highs and two lows a day of about the same size, roughly 12 hours 25 minutes apart.

About this station
- High tide reaches Upper drawbridge, Petaluma River about 9.6 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 131 min later and low tide about 179 min later than there.
- High tide heights run about 1.15 times the reference.
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 Upper drawbridge, Petaluma River from the 1983-2001 National Tidal Datum Epoch; mean higher high water is 6.7 ft above it and mean sea level 3.7 ft. The land survey datum NAVD88, the zero on topographic maps and flood maps, is 0.3 ft above MLLW here, so a water level on this page converts to NAVD88 by subtracting that amount. These datums are controlled from NOAA's San Francisco, CA gauge. Source: NOAA CO-OPS station 9415584, established 1977, gauge removed 2014. 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.
