Aransas Wildlife Refuge, TX Daily Water Report — August 27, 2026

Today, sailing is the standout play along the Aransas Wildlife Refuge coast, with a score that pushes well into excellent territory, while divers and boaters also have good reason to get out. The morning will deliver the most accommodating conditions, but some breeze and a building chop will shape your timing. Winds start light, near 3 knots around sunrise, but strengthen through the morning, settling into a representative 10 knots from the south-southeast with gusts that can reach 18 knots later. That SSE flow should stay steady enough for a satisfying sail, though the gusty periods call for a sharp hand on the sheet. The sea state remains small: waves average 0.42 meters at a short 2.9-second period, with the calmest stretch around 1 p.m. dropping to 0.26 meters. Diving scores a solid 7.9, helped by light wave action and water temperature at 28.9°C, though the water is notably cool for late August—about a degree below the long-term average. Boaters should have a comfortable run with the 7.6 score, especially before the afternoon wind picks up, but the 0.6 meter per second northward current is something to note, particularly near any structure. Fishing sits at 6.4, which tracks with the stable pressure and the main solunar window dropping through the early afternoon, but the lack of tidal data leaves some uncertainty about feeding activity. Wildlife watching earns a 7.4, and that minor solunar period from 6:16 to 7:16 a.m. aligns nicely with dawn, making early morning the best bet for spotting birds or other activity near the shoreline. Surfing and kayaking are middling today, with short-period waves that lack any real push and wind that will make a paddle into the breeze feel like work. The waxing gibbous moon, near full at 98% illumination, will keep the evening bright and the water visible long after sunset. Looking ahead, Thursday brings lighter waves and a slightly higher wind peak near 20 knots, so sailing remains viable but with more gusty moments. Friday and Saturday calm down significantly, with waves dropping to 0.1–0.3 meters and less wind, which should boost kayaking and diving scores. For the best window today, get on the water for the dawn wildlife show, then rig the sail for the building breeze through late morning.
