The tide at Humboldt Bay (North Spit)
Humboldt Bay (North Spit) 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 6.9 ft, and 4.9 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 Humboldt Bay (North Spit) about 7.6 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: 9.9 ft on Dec 31, 2005.
- Lowest on record: -2.9 ft on Jan 20, 1988.
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 Humboldt Bay (North Spit) from the 1983-2001 National Tidal Datum Epoch; mean higher high water is 6.8 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. Source: NOAA CO-OPS station 9418767, established 1977. 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.
