Louisiana Tide Charts

High tide arrives at a different time at each station. Bay Gardene reaches 2.15 ft at 1:47 am; Bay Pomme D'or reaches 1.08 ft at 11:15 pm; Bayou BonFouca, Route 433 reaches 0.8 ft at 8:55 am. The table above lists the next high and the next low for all 83 Louisiana stations.

Joseph Harbor, where high and low water differ by 2.2 ft today. The smallest of the 71 Louisiana stations with a range today is Lafitte, Barataria Waterway at 0.3 ft. Range varies along a coast because the shape of a bay or estuary amplifies or damps the same ocean tide.

Yes, at Bay Pomme D'or, Bayou Chene, Golden Meadow, Plaisance Canal and 7 others. The lowest is -0.54 ft at 11:29 am. A minus tide is water below mean lower low water, the zero point for US predictions, and it exposes ground that is normally covered.

Not all alike. 82 are diurnal and 1 is mixed semidiurnal. Each station page classifies itself from its own predictions rather than from a regional rule, because the pattern changes along a single coast.

NOAA states roughly ten minutes on timing and half a foot on height for a reference station in ordinary weather. 49 of the 83 stations here are reference stations; the rest are subordinate, with times and heights derived from one by a published offset, so expect a little more spread. Weather is the bigger factor either way. A storm surge or a strong onshore wind can raise real water well above the prediction, which is astronomy only.
