About this station
MARTELLO CASTLE, LAKE BORGNE is one of NOAA's reference tide stations — its predictions are computed directly from harmonic analysis of water levels observed here, and other nearby stations are calculated from it.
The northern Gulf runs small, mostly diurnal tides — often just one high and one low a day — where wind and river flow routinely outvote the moon.
