Q. from Chris Morris: I’m
wanting to make sure I have the most official tide chart read outs. Is there
anyway you could tell me where you pull the information from? Or perhaps it is
some sort of prediction algorithm? (I know you couldn’t tell me anything about
that with trade secrets and all.)
A. from Mike Lane: The tide
predictions are derived from formula developed by NOAA.
These predictions are predetermined many years in advance 30-50 years and are
constant. They involve the positions of the sun and moon and are
integrated with observed data for many years by NOAA.
Depending on where you are
fishing or hunting the times and ranges of real tides can be severely affected
by the wind. Especially in Louisiana and Texas. In these cases the
predictions are way off and these predictions are sometimes not very useful.
There are other approaches that
could be used and in some locations are used. With modern electronics tides can be measured in real time and graphed over a period of time.
These real time reporting stations are in short supply because of the
government’s reluctance to fund these type of projects. None of these
predict future tides, but I feel that when you can find these real-time stations
for your area you can do your own amateur predictions that can be helpful.
One day I predict that
scientists will integrate real-time monitoring with current weather data,
weather prediction weighted by existing tide predictions and the results will be
Bad news is that it takes money and fishermen and
hunters in wind affected areas have a very tiny voice.
