Where Eureka Slough Bridge is
Eureka Slough Bridge sits at 40.8067° N, 124.1420° W on the California coast, at Eureka, CA, in Humboldt County. 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 Humboldt Bay (North Spit) (NOAA 9418767), 4.8 mi away, and high and low water here run on average about 26 min later than there. The nearest weather station is Humboldt, CA, a shore station reporting wind and, at most sites, water temperature, 3.5 mi away.
The tide at Eureka Slough Bridge
Eureka Slough Bridge 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 7.4 ft, and 5.4 ft between the average high and the average low, a large tide. On an average day the higher high tops the lower high by 0.7 ft and the lower low sits 1.3 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 Eureka Slough Bridge about 8.2 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 Humboldt Bay (North Spit), station 9418767. High tide comes about 33 min later and low tide about 19 min later than there.
- High tide heights run about 1.08 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 Eureka Slough Bridge from the 1983-2001 National Tidal Datum Epoch; mean higher high water is 7.4 ft above it and mean sea level 4.0 ft. The land survey datum NAVD88, the zero on topographic maps and flood maps, is 0.8 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 Crescent City, CA gauge. Source: NOAA CO-OPS station 9418802, established 1978, gauge removed 1979. 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.
