Freeport Harbor, TX Daily Water Report — August 28, 2026

Full-steam-ahead for boaters and sailors today at Freeport Harbor, with the best window holding through the lunch hours and into early afternoon. A steady southeast breeze around 9 knots, gusting only a hair higher, keeps the sailing score at a commanding 8.8 out of 10—the second highest mark of the past week—while boating posts an 8.3. The wind is consistent enough to fill a main without overpowering a small skiff, and cloud cover sits at a mere 13 percent, so the glare off the water will be manageable for navigation. Waves hover around 0.2 to 0.5 meters all day, with the calmest stretch settling in near 18:00, though the sea state is already gentle enough for most recreational power and sail craft. Diving earns an 8.0, matching some of its better recent marks. Water temperature runs a shade above seasonal average at 31.6°C, and the southeast wind keeps the surface from getting choppy enough to spoil a descent. That said, atmospheric visibility is not underwater visibility—while the air is clear at 21.5 kilometers, no local clarity data is available for the depths. The chlorophyll reading is elevated, but that’s a note for surface conditions, not a guarantee of bottom visibility. Divers who value warm water and light current (0.2 m/s southerly) will find the afternoon ebb tide around low water at 15:28 a logical entry point. Fishing scores a 6.6, a modest step down from yesterday’s 7.1 and Wednesday’s 7.4. The solunar major period from 12:24 to 14:24 aligns with a falling tide and might stir some action, but the high midday sun and stable barometric pressure at 1016 hPa offer no dramatic change. This is not a banner day, though the minor period around moonrise at 19:33 could produce an evening bite as the outgoing tide accelerates toward the 22:22 low. The full moon overhead means stronger tidal swings—note the 0.38-meter range between the high at 05:14 and the low at 22:22. That pull helps keep the dredged channels productive for kayakers as well, though the kayaking score of 6.7 trails Wednesday’s 8.4; the morning breeze will be lighter if you launch before 09:00. Surfing remains a weak 4.5, with a short-period swell of 2.65 seconds and waves barely breaking a half-meter—leave the board on the rack. Looking ahead, Friday and Saturday stay near-perfect for boaters, with waves dropping to 0.1-0.2 meters on Friday and wind peaking around 10 knots. A slight uptick in rain chances by Sunday means the end of the weekend could get sticky. Today’s best bet: time your dive or fishing session around the outgoing tide late this afternoon, and let the southeast breeze carry you home.
