San Luis Pass, TX Daily Water Report — October 8, 2026

San Luis Pass is a strong day for sailing and boating, with a respectable but more conditional window for kayaks and diving. The water is not flat—waves hold around 0.6 to 0.8 m, with a short 4.2-second period and a 0.58 m swell from the southeast—but the north wind is generally manageable at a representative 9 knots. Expect the sharpest gusts early, reaching 16.5 knots around 7:00 AM, before the day settles into a warmer, dry, cloud-free run. For sailors, the mix earns an 8.7/10: enough breeze to work with, without the stronger sustained winds seen earlier this week. Boaters rate 8.2/10, though the short-period chop deserves more respect than the headline wave height suggests. A 0.22 m/s current toward the southwest is another small but real piece of the puzzle, especially around the pass and for paddlers planning a return leg. Kayaking scores 6.6/10, best suited to crews comfortable managing wind, chop and current rather than treating the morning as a glass-calm cruise. The calmest wave reading is near 3:00 AM at 0.64 m, so daylight does not bring a truly quiet-water window. Still, the period around the 9:16 AM low tide may appeal to shoreline explorers, while the afternoon high at 3:00 PM offers a different water level for launch planning. Fishing is a middling 5.8/10; the more favorable solunar major period runs 10:41 AM to 12:41 PM, with rising pressure and no rain in the forecast. That is a timing edge, not a guarantee. Diving rates 8.1/10 on the available conditions, aided by warm 28.5 C marine surface water, though 16 km atmospheric visibility should not be mistaken for underwater clarity. The reported SST is 2 C above average. Compared with the recent record, boating is a touch below yesterday’s 8.5 but well above the windier, rougher setup on October 5; sailing also remains notably capable. Friday looks a little lumpier, with 0.8 to 1.0 m waves possible. The standout in the next several days is Sunday, when waves are forecast at just 0.2 to 0.4 m with light-to-moderate wind. Best bet: rig the sailboat or plan a careful boat run after the early gusts ease, keeping the short chop and pass current firmly in the day plan.
