San Luis Pass, TX Daily Water Report — October 4, 2026

San Luis Pass is a good go for sailboats and a respectable go for most other scored water plans, but it is not a glassy-water day. The NNE wind is running around 12 knots, with a 10–19 knot daily range and early gusts reaching 26 knots, enough to keep paddlers and smaller craft honest. Waves are modest at roughly 0.5–0.8 m, with the calmest forecast near 7 PM, though the short 2.15-second wind-wave component will still add some chop. Sailing gets the day’s strongest score at 8.6/10: enough breeze to work with, manageable wave height, and no meaningful rain expected despite a rain window extending through 7 PM. Boating rates 7.3/10, a step up from yesterday’s 6.5, while kayaking improves slightly to 6.7/10 but remains a tradeoff between warm water and persistent wind exposure. The water is very warm at 29.1 C, and the marine forecast supports diving at 8.2/10; that score reflects the available wind, wave, clarity, and water-temperature inputs, not a guarantee of underwater visibility. Atmospheric visibility is forecast near 14.7 km under complete cloud cover. For fishing, the 7/10 outlook is best used around the morning major solunar period from 7:15 to 9:15 AM, then again after sunset during the 7:15–9:15 PM major period. Pressure is rising through the day toward 1016 hPa, while the tide falls from a 0.59 m high at 2:39 AM toward a 0.10 m low at 5:06 PM. The late-afternoon low-tide approach also helps lift the wildlife outlook to 7.6/10, well above yesterday’s 5.4. Chlorophyll is high at 4.78 mg/m³, but that is a water-color measure, not a wildlife or catch report. Compared with the recent run, today trades the near-calm boating and paddling conditions of October 2 for better sailing and stronger overall fishing and wildlife scores. Monday stays similarly choppy, but Tuesday and Wednesday look like the more forgiving stretch, with 0.3–0.6 m waves and lighter peak winds. Conditions build again Thursday and especially Friday. Best bet: rig for the morning solunar window, let the NNE breeze do the sailing, and save the calmest water expectation for near sunset—not for the launch ramp.
