Where Port Arthur is
Port Arthur sits at 29.8667° N, 93.9300° W on the Texas Gulf coast, at Port Arthur, TX, in Jefferson County. 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 1996. The nearest weather station is Port Arthur, TX, a shore station reporting wind and, at most sites, water temperature, right at this station.
The tide at Port Arthur
Port Arthur 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 1.5 high tides a day here. The mean range from lower low to higher high is 1.0 ft, and 0.8 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 0.1 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 Arthur 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 0.4 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 Texas Point, Sabine Pass, TX gauge. Source: NOAA CO-OPS station 8770475, established 1996. 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.

🌊 Biggest flood tides at Port Arthur this month: Oct 1, Oct 2, Oct 3, Oct 4, Oct 5. These spring highs push water up into the grass and over the oyster rock; prime for poling into flooded marsh for tailing reds.
🔻 Negative (minus) low tides at Port Arthur this month: Oct 27, Oct 28, Oct 29. These drain the flats and expose the oyster rock, prime for sight-fishing and clamming.
