Where Rat Bayou is
Rat Bayou sits at 29.5667° N, 89.7634° W on the northern Gulf of Mexico, at Pointe a la Hache, LA, in Plaquemines Parish. The station here is a historical NOAA reference station: a gauge measured the tide at this spot from 2024 until 2024, and NOAA still publishes harmonic predictions from that record. There is no live reading here today. The closest gauge measuring live water level is Shell Beach, Lake Borgne (NOAA 8761305), 21.5 mi away, and high and low water here run on average about 4 min later than there. The nearest weather station is Shell Beach, LA, a shore station reporting wind and, at most sites, water temperature, 21.5 mi away.
The tide at Rat Bayou
Rat Bayou has a diurnal tide: usually one high and one low a day, with the daily rhythm shifting about 50 minutes later each day and fading near the moon's equatorial crossing. This month's predictions average 1.1 high tides a day here. The mean range from lower low to higher high is 0.5 ft, a small tide. For the water around it: Northern Gulf tides are diurnal, one high and one low most days with ranges of 1 to 2 ft, so wind and river stage move the water as much as the moon.
Datum and source
Heights on this page are feet above mean lower low water (MLLW), the zero NOAA's nautical charts use for soundings. A predicted 0.0 ft low is the average of the lower low each day; a minus tide is water below chart datum, and a 2 ft high means 2 ft more water than the chart shows. NOAA fixes MLLW at Rat Bayou from the 2012-2016 National Tidal Datum Epoch; mean higher high water is 0.5 ft above it and mean sea level 0.2 ft. The land survey datum NAVD88, the zero on topographic maps and flood maps, is 0.9 ft below MLLW here, so a water level on this page converts to NAVD88 by adding that amount. These datums are controlled from NOAA's Grand Isle, LA gauge. Source: NOAA CO-OPS station 8761431, established 2024, gauge removed 2024. The tide times and heights are NOAA's official harmonic predictions for this station; TidalMap republishes them daily and does not alter them.
