CatchWindow fishing intelligence

Port O'Connor, TX Daily Water Report — August 27, 2026

Sailing takes the top slot today, and it’s the clear winner for anyone wanting to make miles on the water. Winds out of the south are holding steady around 9 knots with gusts into the mid-teens, which is ideal for a sporty reach without overwhelming the rail. The sea is cooperating too — wave heights hover under half a meter, and the wind wave period is short enough that the chop stays manageable. If you’ve got a skiff or a daysailer, the window from mid-morning through early afternoon looks best, especially around 13:00 when the forecast shows the calmest seas of the day at 0.34 meters. That’s a noticeable drop from yesterday’s lumpier 0.5-meter range, and it makes for a smoother ride. Boating scores nearly as high, though the slight uptick in wind later in the afternoon deserves respect. The ocean current is running north at 0.6 meters per second, which could add a knot or two of drift if you’re running against it. Diving remains strong at 7.8 out of 10, matching yesterday’s score, with calm wave faces and a surface temperature near 31°C making for comfortable bottom time. Visibility is listed at nearly 17 kilometers above the surface, but don’t confuse that with underwater clarity — subsurface visibility is a separate beast and isn’t measured here. The water temperature is running half a degree below the long-term average for late August, which is negligible. Fishing sits at a solid 6.9, dragged down slightly by the midday solunar minor period falling at 06:15 to 07:15, which is already past dawn. The major period from 11:45 to 13:45 lines up with the calmest seas and stable pressure, so that’s your best bet for working structure or drifting bait. Surfing remains marginal. The swell is tiny at 0.14 meters with a 4.4-second period from the southeast, and wind waves are dominating the spectrum. It’s a groomed lake out there, not a wave farm. Kayaking rates a 6, perfectly doable for a paddle along the shoreline but not the day for a crossing — that southerly breeze will build by late afternoon. Compared to recent history, today’s sailing score is a tick below the 9.2 we saw back on August 24, when winds were a touch stronger and more consistent. Fishing is also lower than Monday’s 7.1, largely because the tidal data is absent and the solunar timing is less favorable. Wildlife viewing scores 6.5, which is average — the moon is nearly full, so nocturnal feeding activity may not translate to daytime shows. Looking ahead, Thursday and Friday offer even lighter winds and smaller seas, with wave heights dropping as low as 0.1 to 0.3 meters by Friday. That’s prime flat-water paddling territory, but it will pull sailing scores down. By the weekend, a slight building trend returns with waves edging toward 0.6 meters and winds picking up again. Best bet: If you’re on the water by 11:45 today, you’ll hit the solunar sweet spot with the glassiest seas of the afternoon.
