Where Shell Island is
Shell Island sits at 29.4733° N, 91.3050° W on the northern Gulf of Mexico, about 14 mi south of Patterson, LA. The station here is a subordinate tide prediction point. NOAA has no gauge in the water at this spot; its times and heights are published as offsets from a reference gauge, named below. The closest gauge measuring live water level is Lawma, Amerada Pass (NOAA 8764227), 2.6 mi away, and high and low water here run on average about 46 min later than there. The nearest weather station is LAWMA, Amerada Pass, LA, a shore station reporting wind and, at most sites, water temperature, 2.6 mi away.
The tide at Shell Island
Shell Island 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 1.4 high tides a day here. 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.
About this station
- NOAA predicts tides here from Galveston, Galveston Channel, station 8771450. High tide comes about 54 min later and low tide about 39 min earlier than there.
- High tide heights run about 1.07 times the reference.
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 publishes no datums for this point. Its predictions are offsets from Galveston, Galveston Channel and are referenced to MLLW there. Source: NOAA CO-OPS station 8764165, established 1960, gauge removed 1961. The tide times and heights are published as time and height offsets from its reference gauge; TidalMap republishes them daily and does not alter them.
