Which Tide Book to Use?

May 31, 2013

NOAA says when discrepancies appear in different versions of tide books, trust their website for the most accurate, up-to-date predictions of tides.

DILLINGHAM:  Last week, some close observers brought to our attention an interesting problem:  the two different versions of tide books freely available around Dillingham have different times and heights for the predicted tides of the Nushagak district, as measured at Clark’s Point.   

And neither one of the versions aligned with the tide tables on NOAA’s website.    

As an example, the afternoon high tide on June 21st could either be at 12:01 noon with 18.8 feet, or 1:02 pm with 17.4 feet … or somewhere in between.    

Of course everyone can determine for his or herself how big of a deal those discrepancies are, but we wanted to know exactly where does one find the most accurate predictions for tides in Bristol Bay?

KDLG’s Dave Bendinger reports:

**The most up-to-date, accurate tide predictions for stations in Alaska can be found at this NOAA website.

Listen below as Stephen Gill gives a bit more technical understanding of the difference between NOAA's predictions for the Clark's Point station and last summer's observations:
