Where San Martin Lake Channel is
San Martin Lake Channel sits at 26.0018° N, 97.2986° W on the Texas Gulf coast, at Brownsville, TX, in Cameron County. The station here is a historical NOAA reference station: a gauge measured the tide at this spot from 2019 until 2020, and NOAA still publishes harmonic predictions from that record. There is no live reading here today. The closest gauge measuring live water level is Port Isabel (NOAA 8779770), 6.6 mi away, and high and low water here run on average about 26 min later than there. The nearest weather station is Port Isabel, TX, a shore station reporting wind and, at most sites, water temperature, 6.6 mi away.
The tide at San Martin Lake Channel
San Martin Lake Channel 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 1.4 ft, and 1.1 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 San Martin Lake Channel from the 1983-2001 National Tidal Datum Epoch; mean higher high water is 1.4 ft above it and mean sea level 0.8 ft. The land survey datum NAVD88, the zero on topographic maps and flood maps, is 0.9 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 8779911, established 2019, gauge removed 2020. 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 San Martin Lake Channel 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 San Martin Lake Channel this month: Oct 28, Oct 29, Oct 30. These drain the flats and expose the oyster rock, prime for sight-fishing and clamming.
