I've bought the eldridge tide table book to assist with our trip north this year.
I'm looking at St. Augustine City Dock
for May 3rd
Following the directions from the book I have located the tide prediction for our desired station then added (in this instance 10 minutes) to the the base station, which is "Battery".
So, that would indicate that high tide should occur at 5:49 AM since The Battery
high tide is at 5:39 AM.
However, the online tide tables indicate a high tide at 6 AM.
Are I doing this incorrectly or is there a factor I am not taking into consideration?
