Where Red Bluff Bay is
Red Bluff Bay sits at 56.8567° N, 134.7230° W on Southeast Alaska's Inside Passage, at Sitka, AK, in Sitka. The station here is a historical NOAA reference station: a gauge measured the tide at this spot from 1926 until 2013, and NOAA still publishes harmonic predictions from that record. There is no live reading here today. The closest gauge measuring live water level is Sitka (NOAA 9451600), 27.0 mi away, and high and low water here run on average about 10 min later than there. The nearest weather station is Point Gardner, a shore station reporting wind and, at most sites, water temperature, 11.7 mi away.
The tide at Red Bluff Bay
Red Bluff Bay has a semidiurnal tide: two highs and two lows a day of about the same size, roughly 12 hours 25 minutes apart. This month's predictions average 1.9 high tides a day here. The mean range from lower low to higher high is 12.8 ft, and 10.4 ft between the average high and the average low, a large tide. On an average day the higher high tops the lower high by 0.9 ft and the lower low sits 1.5 ft below the other low. For the water around it: Inside Passage tides are large and mixed semidiurnal, two highs and two lows a day with ranges of 12 to 20 ft that drive fast currents in the narrows.
About this station
- High tide reaches Red Bluff Bay about 9.7 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 Red Bluff Bay from the 1983-2001 National Tidal Datum Epoch; mean higher high water is 12.8 ft above it and mean sea level 6.8 ft. These datums are controlled from NOAA's Port Alexander, AK gauge. Source: NOAA CO-OPS station 9451467, established 1926, gauge removed 2013. The tide times and heights are NOAA's official harmonic predictions for this station; TidalMap republishes them daily and does not alter them.
