USS Lexington, Corpus Christi Bay, TX Daily Water Report — August 27, 2026

Sailing is the clear winner on Corpus Christi Bay today, and it’s not a close call. With a score of 8.3 out of 10, the southeast breeze at 8 knots gusting to 18 provides enough pressure for a lively reach without turning the bay into a washing machine. The wind builds through the morning, so if you’re rigging up, aim for a late-morning launch and plan to be off the water before that 21:00 gust spike near 19 knots. The wave heights stay modest at half a meter or less, which is just enough chop to keep the rail in the water. Boating and diving both come in at 7.8, sharing second place for the day. Powerboaters will find the same steady southeast wind manageable, and the calmest window around 13:00—when waves drop to 0.3 meters—makes for a smooth run. Divers should note that while the surface conditions are cooperative, the water temperature sits at a toasty 30.5°C, which is 0.4 degrees cooler than the seasonal average. That slight dip might be a welcome relief in late August, but don’t expect any thermocline drama in shallow bay waters. Fishing scores a respectable 6.9, buoyed by a midday solunar major period from 11:49 to 13:49. The stable barometer and light rain chance play in your favor, but the stiffening afternoon breeze could make anchoring tricky on exposed flats. Wildlife watchers land at 7.7, and that minor solunar window from 18:19 to 19:19 aligns nicely with dusk at 20:22, giving you a solid evening window to spot birds working the shallows. Kayakers face a tougher call at 5.8—the 0.4-meter wind waves are manageable for experienced paddlers, but the building breeze will punish a slow return leg. Surfing scrapes by at 5.1, which is typical for this stretch of coast in summer. The 0.18-meter swell from 125 degrees with a sub-3-second period won’t produce anything rideable, and the onshore wind adds mush to the equation. If you’ve got the itch, wait for a cleaner day. Compared to yesterday’s lighter 3.6-knot breeze, today trades glassy calm for consistent sailing conditions. That 8.3 sailing score is a healthy rebound from yesterday’s 5.9, and the fishing uptick from 7.9 to 6.9 reflects the midday solunar bump, though the wind erodes the earlier high. The next few days lean lighter: Friday and Saturday keep waves below half a meter with peak winds near 13 knots, good news for divers and paddlers. By Sunday, the wind climbs back toward 15 knots and waves push to 0.7 meters, which will favor sailors and powerboaters again. Best bet: launch by 10:00 for a clean sail before the breeze stiffens past noon.
