How to use the following data to SET a Tide Clock.

This only needs to be done ONCE, but information for each day is provided, if you need to change the battery, or want to examine how accurate the Quartz XTAL (or pendulum) is running in the clock.

There are four sets of numbers in each line:

The first number if (+ve) is the number of minutes the TIDE CLOCK is set LATER to the NOAA tide, or if (-ve) EARLIER to the NOAA Tide.

THe second number is the NOAA Harmonic prediction for HIGH for that tide.

The third number is the HH:MM:SS you should set the Tide Clock at HIGH, or compare to an already set clock, to see how accurate its timekeeping is. This advances by a constant 12:25:14 for each HIGH tide.

The fourth number is the height of the tide at the NOAA predicted time using the datum of MSL (Mean Sea Level).

All times EST.
