CatchWindow fishing intelligence

Aransas, Aransas Pass, TX Daily Water Report — August 27, 2026

Let’s call today a solid all-around day for getting on the water, with one standout window and a few tradeoffs depending on what you’re after. The best bet is this afternoon. Winds are running 8 knots from the SSE with gusts near 17 knots, but they settle through the middle of the day, and the calmest wave heights—around a third of a meter—line up near 1:00 PM. That’s your sweet spot for boating, which scores an 8 out of 10, and sailing, which edges higher to 8 out of 10 thanks to a consistent breeze and mostly clear skies. Diving is also strong at 7.6, buoyed by flat seas and water sitting at 30°C, though remember atmospheric visibility of 17.7 kilometers has no bearing on what you’ll see below. Fishing scores a 7.2, and the solunar setup is worth noting. The major period around midday is prime, running from 11:47 to 1:47, and with high pressure stable at 1013 hPa, the fish should be predictable rather than spooky. That said, no tide data is available for this location today, which is a gap—if you rely on tidal movement, you’ll want to lean on the solunar timing more heavily. Compared to yesterday, conditions are similar but a touch breezier, so the slight drop in diving and boating scores from the recent 7.9 and 8.3 highs makes sense. The surf is marginal at 5.1 with short-period wind waves barely hitting half a meter, so leave the shortboard at home. Kayaking rates a 6, which is workable but not ideal for a long paddle into the wind this morning. Wildlife scores 6.8, decent for an afternoon cruise if you time it during the minor period that ends at 7:17 PM, when animals may be more active. For the coming days, expect light winds and small waves to persist through Saturday, then a gradual bump in wave height and wind speeds toward Monday and Tuesday as a more energetic pattern sets up. By Tuesday, seas could reach 0.7 meters with gusts approaching 17 knots, so get your calm-water plans in before the weekend ends.
