CatchWindow fishing intelligence

Port O'Connor, TX Daily Water Report — August 28, 2026

It’s a solid boating day ahead, with the best window shaping up from mid-morning through early afternoon as winds stay under 10 knots and the sea surface remains nearly flat. A Full Moon overhead and a rising barometer make for stable, pleasant conditions on the water, though the stiff humidity and heat index near 40 C mean you’ll want to stay hydrated and keep sun protection handy. For boaters, this is your top tier of the week. The wave height hovers around 0.3 meters all day, with the calmest stretch near 3 PM when the modeled minimum dips to 0.28 meters. East winds hold steady around 6 knots, gusting only to 7 in the representative reading, though expect a brief uptick near sunset when gusts may approach 17 knots. That’s a minor wrinkle, not a dealbreaker. Sailing scores a 7.3, a step down from yesterday’s 8.5 as the breeze is lighter and less consistent, but still workable for a relaxed reach. Kayaking and diving both post scores in the high 7s, helped by light wind, low wave action, and a measured ocean current of 0.2 m/s moving west. Diving conditions mirror yesterday’s 7.8, and the slight negative sea-surface temperature anomaly of half a degree Celsius relative to the long-term average won’t be felt given the 31 C water. Fishing lands a 6.5, a slight drop from recent days. The solunar major period from 12:29 to 2:29 PM aligns with the low-to-rising tide transition, but the tide range is minimal—barely 0.16 meters separating the high and low at 0.23 and 0.07 meters, respectively. That slack tidal movement reduces water exchange and may concentrate activity in fewer windows. The minor solunar period near 7 AM could produce a brief flurry around dawn. Surfing remains a 4.5, unchanged from yesterday’s mediocrity, with the short-period swell at 2.7 seconds offering little push. Looking ahead, Friday and Saturday bring slightly warmer air and a gradual uptick in peak winds to around 12 knots, though wave heights stay small at 0.3 to 0.5 meters. Precipitation chances remain low, staying below 20 percent through Tuesday. Sunday may see a fresher breeze near 15 knots, which would sharpen up sailing and boating conditions but keep the bay calm enough for most trailers. Best bet: Get out there by 10 AM, when the outgoing tide and light easterly breeze give you a flat, clear run before the afternoon heat sets in.
