Where Alameda is
Alameda sits at 37.7720° N, 122.3003° W on San Francisco Bay, at Alameda, CA, in Alameda County. The station here is a NOAA gauge reporting live water levels. It has been in NOAA's records since 1939. The nearest weather station is Alameda, CA, a shore station reporting wind and, at most sites, water temperature, right at this station.
The tide at Alameda
Alameda 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 6.6 ft, and 4.8 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 1.1 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 Alameda 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.
- Highest water on record: 9.7 ft on Dec 3, 1983.
- Lowest on record: -2.6 ft on Jan 11, 2009.
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 Alameda from the 1983-2001 National Tidal Datum Epoch; mean higher high water is 6.6 ft above it and mean sea level 3.5 ft. The land survey datum NAVD88, the zero on topographic maps and flood maps, is 0.2 ft above MLLW here, so a water level on this page converts to NAVD88 by subtracting that amount. Source: NOAA CO-OPS station 9414750, established 1939. The tide times and heights are NOAA's official harmonic predictions for this station; TidalMap republishes them daily and does not alter them. The observed line is the gauge's own six-minute water level feed.
