Port Aransas, TX Daily Water Report — October 5, 2026

Port Aransas gets a qualified green light today: best for sailors and divers, workable for boaters and anglers, and a more deliberate proposition for paddlers. The water is warm, the pressure is steady, and there is no rain indicated—but the NNE breeze has enough teeth to keep the day from being a casual float. Winds run roughly 8 to 14 knots, with the sharpest gusts near 26 knots around 8 AM. That favors sailors, whose 7.5/10 outlook leads the board, but it also means crews should expect a gusty start rather than a perfectly trimmed morning. Waves hold around 0.8 to 1.0 m, with a representative 0.92 m at a short 4.35-second period. Add 0.72 m wind waves and a current near 0.42 m/s toward 210 degrees, and small craft have enough moving parts to warrant good judgment. Kayaking rates 5.4/10: possible, not plush. Diving earns 7.2/10, supported by 29.3 C marine SST and manageable wave heights, though surface chop can still complicate entries and exits. The reported 13.9 km atmospheric visibility is useful above water, not a promise of underwater clarity. Boating sits at 6.3/10, a step up from yesterday’s 5.6 but well below the notably easier reconstructed conditions on October 2 and 3, when boating scored above 8. Fishing is a middle-of-the-pack 5.9/10. The more favorable timing is the 8:21–10:21 AM solunar major period, with another major window from 8:21–10:21 PM; the late-day low tide arrives at 5:54 PM. Cloud cover is heavy at 93%, temperatures range from 23.3 to 27.9 C, and the pressure is stable near 1014 hPa. The sea is also warmer than average by 2.5 C, though that anomaly alone does not tell us what is happening below the surface. Tuesday looks calmer, with 0.6–0.8 m waves and lighter peak wind, before wind and rain chances build later in the week; Friday currently carries the roughest marine outlook, at 1.0–1.2 m waves. Best bet: sail or dive after the early gust peak, then let the evening tide change—not bravado—decide how long you stay out.
