Where Southwest Pass is
Southwest Pass sits at 28.9317° N, 89.4283° W on the northern Gulf of Mexico, about 24 mi south of Venice, 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 Pilots Station East, SW Pass (NOAA 8760922), 1.3 mi away, and the tide here runs on nearly the same clock. The nearest weather station is Pilot's Station East, SW Pass, LA, a shore station reporting wind and, at most sites, water temperature, 1.3 mi away.
The tide at Southwest Pass
Southwest Pass 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. 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.

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 South Pass and are referenced to MLLW there. Source: NOAA CO-OPS station 8760959. 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.
