Where Mermentau River, Grand Chenier is
Mermentau River, Grand Chenier sits at 29.7750° N, 93.0083° W on the northern Gulf of Mexico, about 12 mi east of Cameron, LA, in Cameron Parish. The station here is a historical NOAA reference station: a gauge measured the tide at this spot from 1989 until 2020, and NOAA still publishes harmonic predictions from that record. There is no live reading here today. The closest gauge measuring live water level is Calcasieu Pass (NOAA 8768094), 20.1 mi away, and high and low water here run on average about 33 min later than there. The nearest weather station is Grand Chenier, an airport reporting wind, visibility and sky cover, but no water temperature, 12.4 mi away.
The tide at Mermentau River, Grand Chenier
Mermentau River, Grand Chenier has a mixed tide: two highs and two lows a day, but of unequal size, so one low each day drains a little lower than the other. This month's predictions average 1.7 high tides a day here. The mean range from lower low to higher high is 1.8 ft, and 1.3 ft between the average high and the average low, a small tide. On an average day the higher high tops the lower high by 0.1 ft and the lower low sits 0.4 ft below the other low. 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 Mermentau River, Grand Chenier from the 1983-2001 National Tidal Datum Epoch; mean higher high water is 1.8 ft above it and mean sea level 1.0 ft. The land survey datum NAVD88, the zero on topographic maps and flood maps, is 1.4 ft above MLLW here, so a water level on this page converts to NAVD88 by subtracting that amount. These datums are controlled from NOAA's Calcasieu Pass, LA gauge. Source: NOAA CO-OPS station 8767403, established 1989, gauge removed 2020. The tide times and heights are NOAA's official harmonic predictions for this station; TidalMap republishes them daily and does not alter them.
