About this station
- High tide reaches Zachary Bay, Unga Island about 11.3 hours after the moon passes overhead. That lag is local, which is why high water does not line up with the moon.
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 Zachary Bay, Unga Island 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. These datums are controlled from NOAA's Sand Point, AK gauge. Source: NOAA CO-OPS station 9459465, established 1954, gauge removed 2017. The tide times and heights are NOAA's official harmonic predictions for this station; TidalMap republishes them daily and does not alter them.
