Today on the water at SW Pass
Today at SW Pass: high tide at 12:12 AM (1.9 ft), low tide at 12:30 PM (-0.1 ft). The National Weather Service forecast for Saturday is showers and thunderstorms likely with E winds 10 to 15 mph, 78°F. Wind that strong can hold water in or push it out, so the real tide may run above or below these predictions. Sunrise is at 7:08 AM and sunset at 6:13 PM.
| Period | Forecast | Wind | Temp |
|---|---|---|---|
| Overnight | Mostly Cloudy | E 15 mph | 74°F |

Where SW Pass is
SW Pass sits at 28.9250° N, 89.4183° W on the northern Gulf of Mexico, about 24 mi south of Venice, LA. The station here is a historical NOAA reference station: a gauge measured the tide at this spot from 1996 until 2004, and NOAA still publishes harmonic predictions from that record. There is no live reading here today. The closest gauge measuring live water level is Pilots Station East, SW Pass (NOAA 8760922), 0.8 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, 0.8 mi away.
The tide at SW Pass
SW 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. The mean range from lower low to higher high is 1.3 ft, and 1.2 ft between the average high and the average low, a small tide. 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.
About this station

- Lowest on record: -1.9 ft on Jan 19, 2003.
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 SW Pass from the 2012-2016 National Tidal Datum Epoch; mean higher high water is 1.3 ft above it and mean sea level 0.6 ft. These datums are controlled from NOAA's Grand Isle, LA gauge. Source: NOAA CO-OPS station 8760943, established 1996, gauge removed 2004. The tide times and heights are NOAA's official harmonic predictions for this station; TidalMap republishes them daily and does not alter them.

TidalMapMonthly tide calendar
🌊 Biggest flood tides at SW Pass this month: Oct 2, Oct 3, Oct 4, Oct 27, Oct 28, Oct 29, Oct 31. 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 SW Pass this month: Oct 2, Oct 3, Oct 28, Oct 29, Oct 30, Oct 31. These drain the flats and expose the oyster rock, prime for sight-fishing and clamming.
Best fishing times (solunar)
Major and minor solunar windows for SW Pass, peak feeding activity is around the moon overhead/underfoot (majors) and moonrise/moonset (minors). Score is the day's activity coefficient (0–100).
