About 20+ years ago, I wrote a small basic program for a Yacht Club. The data was available from a US government agency for a specific geographic location. The Yacht Club knew that their location was 1 hour 22 minutes behind the tide for that specific geographic location. With that information the program produced a chart something like the following for the entire year:
Tides for ____________________ starting with November 1, 2011.
Day High Tide Height Sunrise Moon Time % Moon
/Low Time Feet Sunset Visible
Tu 1 High 3:41 AM 3.0 7:43 AM Rise 1:23 PM 31
1 Low 11:14 AM 0.2 6:47 PM
1 High 5:57 PM 2.2
1 Low 11:06 PM 1.1
The only calculations the program made was to adjust the 'Tide Time'.
For perl to do this the script would be trivial.
From this discussion, it sounds like I needed to account for a lot more.
Isn't tide predicting mostly an approximation?
