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

Port Arthur gets a clear green light for most water time today, with boating the standout at 7.8/10 and a notably gentle sea state. This is a low-wave day rather than a no-attention-needed day: seas run about 0.1 to 0.3 meters, with the calmest water near 9 PM around 0.12 meters, while NNE wind ranges from roughly 5 to 11 knots and evening gusts may reach 19 knots. The best all-around launch window is early, from dawn through the morning solunar major period of 7:10 to 9:10 AM. The 5:41 AM high tide will be easing out, pressure is rising toward 1016 hPa, and the small 0.14-meter waves should keep the ride civilized for boaters and paddlers. Kayaking rates 7.2/10, but the gust spread deserves respect, especially in exposed water where a modest sustained breeze can become a more argumentative paddle home. Fishing earns 6.7/10, helped by the morning major period and a second major window from 7:10 to 9:10 PM. The evening option coincides with the day’s lowest tide at 6:56 PM and the strongest forecast gusts around 7 PM, so it is more of a selective shoreline or protected-water play than a blanket endorsement. The water is warm at 29.1 C, about 2.1 C above average. Chlorophyll is very high at 7.33 mg/m³, indicating bloom conditions; that is a water-quality and clarity consideration, not a promise of fish activity. Diving scores 7.1/10 on the available wind, wave, clarity, and temperature inputs, but atmospheric visibility near 12.9 km is not underwater visibility. Cloud cover is complete, and the forecast rain window extends from 4 AM to 7 PM despite zero representative precipitation, so keep expectations flexible. Compared with the recent run, boating is a touch below yesterday’s 7.9 but remains solid; kayaking is also slightly softer than yesterday, while fishing improves from 6.0. The next few days stay generally manageable, with especially light waves forecast Tuesday and Wednesday before seas build to 0.3–0.6 meters Friday. Best bet: launch early for the outgoing tide, glassy-to-small water, and a morning that should behave better than the gustier evening.
