Port Lavaca, TX Daily Water Report — October 4, 2026

Port Lavaca gets a qualified green light today: excellent sailing water, workable boating and fishing, and a better-than-average case for diving—but the NNE breeze makes this more of a purposeful outing than a lazy drift day. The water itself stays small, with waves running roughly 0.2 to 0.4 m and a modest 0.08 m swell. That is the good news. The tradeoff is wind: a representative 13 knots from the NNE, with gusts to 18 knots and a stronger 27-knot gust noted around midnight. Sailors have the clearest advantage at 8.5/10, with enough breeze to keep things moving without much sea state. Boaters rate 6.1/10 and paddlers 5.6/10; the short wind waves may be minor in height, but they can still make exposed routes feel busier than the numbers suggest. For anglers, the strongest timing overlaps the morning solunar major period from 7:21 to 9:21 AM, closely following the 7:54 AM high tide. Fishing scores 6.9/10, helped by rising pressure around 1015 hPa and a generally manageable tide-and-wind setup. A second major period arrives from 7:21 to 9:21 PM, although the day’s calmest wave height—about 0.18 m—is forecast near 9 PM, after sunset at 7:11 PM. Plan lighting and return margins accordingly. Diving rates 7.7/10, just a notch below the last two days’ 7.8, with low waves supporting the outlook. Still, the 17.7 km weather visibility is atmospheric, not a measure of underwater clarity, and water temperature is unavailable. Cloud cover is complete, rain is not indicated, and air temperatures stay mild in the mid-20s C. Compared with yesterday, wind is up from 10.3 knots and boating has slipped from 7.3 to 6.1, while sailing remains strong despite easing from 9.2. The next few days retain low seas; winds remain fairly fresh Monday and Tuesday before easing Wednesday, which may be the more comfortable small-craft window. Best bet: rig the sail early, enjoy the high-tide morning period, and let the NNE breeze do the work—without letting it make the decisions.
