Where Shoalwater Flats, Espiritu Santo Bay is
Shoalwater Flats, Espiritu Santo Bay sits at 28.3645° N, 96.5803° W on the Texas Gulf coast, about 8 mi east of Seadrift, TX, in Calhoun County. The station here is a historical NOAA reference station: a gauge measured the tide at this spot from 2019 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 Seadrift (NOAA 8773037), 8.5 mi away, and high and low water here run on average about 173 min earlier than there. The nearest weather station is Seadrift, a tide-station weather package reporting wind and water temperature, 8.5 mi away.
The tide at Shoalwater Flats, Espiritu Santo Bay
Shoalwater Flats, Espiritu Santo Bay 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 1.0 high tides a day here. The mean range from lower low to higher high is 0.3 ft, a small tide. For the water around it: Texas tides are diurnal, usually one high and one low a day with a range near 1 to 2 ft, and a steady wind can hold the predicted tide off by a foot.
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 Shoalwater Flats, Espiritu Santo Bay from the 1983-2001 National Tidal Datum Epoch; mean higher high water is 0.3 ft above it and mean sea level 0.2 ft. The land survey datum NAVD88, the zero on topographic maps and flood maps, is 0.5 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 Rockport, TX gauge. Source: NOAA CO-OPS station 8773896, established 2019, 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.
