Where Port Aransas (H. Caldwell Pier) is
Port Aransas (H. Caldwell Pier) sits at 27.8267° N, 97.0500° W on the Texas Gulf coast, at Port Aransas, TX. The station here is a historical NOAA reference station: a gauge measured the tide at this spot from 1958 until 1984, and NOAA still publishes harmonic predictions from that record. There is no live reading here today. The closest gauge measuring live water level is Aransas, Aransas Pass (NOAA 8775241), 1.0 mi away, and high and low water here run on average about 8 min earlier than there. The nearest weather station is Ship Channel, Mission-Aransas Reserve, TX, a shore station reporting wind and, at most sites, water temperature, 0.8 mi away.
The tide at Port Aransas (H. Caldwell Pier)
Port Aransas (H. Caldwell Pier) 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 1.3 high tides a day here. The mean range from lower low to higher high is 1.6 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 0.2 ft below the other low. 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 Port Aransas (H. Caldwell Pier) from the 1983-2001 National Tidal Datum Epoch; mean higher high water is 1.6 ft above it and mean sea level 0.9 ft. The land survey datum NAVD88, the zero on topographic maps and flood maps, is 0.5 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 Port Isabel, TX gauge. Source: NOAA CO-OPS station 8775270, established 1958, gauge removed 1984. The tide times and heights are NOAA's official harmonic predictions for this station; TidalMap republishes them daily and does not alter them.
