Where Port Aransas is
Port Aransas sits at 27.8397° N, 97.0725° W on the Texas Gulf coast, at Port Aransas, TX. The station here is a live gauge in a NOAA PORTS harbor system, reporting water level in near real time for commercial traffic. It has been in NOAA's records since 1990. The nearest weather station is Port Aransas, a tide-station weather package reporting wind and water temperature, right at this station.
The tide at Port Aransas
Port Aransas 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. The mean range from lower low to higher high is 1.0 ft, and 0.9 ft between the average high and the average low, a small tide. On an average day the higher high tops the lower high by 0.0 ft and the lower low sits 0.1 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 from the 1983-2001 National Tidal Datum Epoch; mean higher high water is 1.0 ft above it and mean sea level 0.6 ft. The land survey datum NAVD88, the zero on topographic maps and flood maps, is 0.1 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 8775237, established 1990. The tide times and heights are NOAA's official harmonic predictions for this station; TidalMap republishes them daily and does not alter them. The observed line is the gauge's own six-minute water level feed.
