CatchWindow fishing intelligence

Port Arthur, TX Daily Water Report — October 7, 2026

Port Arthur gets a clear green light for getting afloat today, with boating the standout at 9.1/10 and kayaking close behind at 8.3/10. The water is exceptionally flat by the forecast: wave height holds at 0.1 m, with only a tiny 0.08 m swell and essentially no wind-wave contribution. A light NNE breeze, generally 2 to 8 knots, keeps the surface manageable without making sails work especially hard. Sailing still rates a respectable 7.1/10, but this is more of a quiet trim-and-drift day than a lively breeze day. The most comfortable all-purpose window runs from dawn through the afternoon high tide at 2:47 PM. Sunrise is 7:13 AM, and the low tide at 10:39 AM is only 0.34 m before water rises modestly to 0.40 m. That small tidal range means little dramatic water movement is expected from the tide table alone, though shallow-water users should still give the 10:39 AM low and the much lower 0.20 m low at 10:10 PM their due. The current forecast is light, about 0.08 m/s toward the southwest. Fishing is a middling 5.7/10 rather than a runaway call, despite the easy boat conditions. The better timing is the 9:50–11:50 AM solunar major period, which overlaps the late-morning low, with another major period from 9:50–11:50 PM. Pressure is rising from around 1012 hPa, and the day stays dry, warm, and nearly cloudless. Air temperatures climb from the low 20s C into the low 30s C, while marine water temperature is 28.5 C. Atmospheric visibility is forecast near 13.2 km; that is not a measure of underwater clarity. Compared with the recent reconstructed CatchWindow history, today is calmer and better for boating and paddling than the last several days, while sailing slips from yesterday’s stronger 8.8/10 in the lighter wind. Diving has no usable score today, so it is not a recommendation. Thursday brings slightly higher 0.1–0.3 m waves; Friday adds stronger wind near 13 knots. The flattest next stretch appears Sunday and Monday, when waves are forecast back near 0.1 m. Best bet: launch early, enjoy the glassy water through the late-morning solunar window, and be back with plenty of daylight before the late low tide.
