CatchWindow fishing intelligence

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

Port Aransas gets a qualified go today: good for sailing and diving on the scorecard, workable for fishing, but a noticeably less friendly day for small, exposed craft than the last several mornings. The water is warm at 29.6 C, seas are modest rather than flat at 0.8–1.0 m, and a NNE wind near 10 knots—with gusts reaching 20 knots and stronger overnight—adds enough texture to keep complacency ashore. The best all-around daylight window is around midday into early afternoon, when waves reach their daily minimum near 0.8 m around 13:00. That is also the practical choice for boaters and paddlers looking to avoid the rougher overnight gust profile, though rain is forecast through 20:00 and atmospheric visibility is only 1.4 km. That visibility figure is for the air, not underwater clarity, but it is still a meaningful navigation and lookout limitation. Fishing rates 6.9/10, with the strongest solunar major period running 07:24–09:24, shortly after sunrise, and another after dark from 19:24–21:24. The falling tide runs toward the 16:29 low, while pressure is rising through the day from a 1011.7–1016.5 hPa range. Wildlife scores 7.2/10, with the low-tide approach and morning solunar period offering the better timing for shoreline explorers. Sailing leads the activity scores at 7.8/10, with enough breeze to work with but a gust spread worth respecting. Diving remains a solid 7.4/10, matching yesterday’s score, aided by warm water and manageable seas; conditions are not a safety guarantee, and the rainy, low-visibility atmosphere is a reason to keep surface planning conservative. Kayaking falls to 4.5/10 and boating to 5.6/10, both down sharply from yesterday’s calmer setup. Compared with October 3, wind has risen from 6.6 knots to a 10-knot representative value, while boating and kayaking scores have taken the clearest hit. The next few days look more favorable for sea state: waves ease to 0.6–0.8 m Tuesday and 0.5–0.8 m Wednesday before building again late week. Best bet: sail the midday lull, fish the sunrise solunar window, and let the gusts—not the warm water—set the day’s limits.
