No - LAT is "Lowest Astronomical Tide" or the lowest tide that would be
predicted. LLWLT,
or "Lower Low Water Large Tide" is the average of the lowest low water for
each year in a
19 year cycle.

Presumably, LAT would be the lowest of the lowest low water in the 19 year
cycle, not the
average.


That would really depend on whether the lowest low had been predicted,
wouldn't it?

Anyway, LAT is much better than LLWLT.

For one thing, you can remember the letters without having to look them up!
