Port Aransas Fishing Report: Week of Aug 3, 2026

WEEK AT A GLANCE

Daytime highs range from 85°F to 90°F, overnight lows 81°F to 82°F. Winds predominantly out of the SSE.

OUR READ ON THE WEEK

Winds stay locked out of the SSE all week, climbing from a comfortable 3–13 mph on Saturday to a steady 15–17 mph by Thursday and Friday — that persistent onshore push will keep the surf churned and the Corpus Christi Ship Channel choppy through the latter half of the week, so plan your bay crossings accordingly. The good news for inshore water clarity is that a sustained south-to-southeast flow, while it builds some chop, doesn't hammer the back bays the way a hard east wind does; the ICW and sheltered coves on the island's bay side should hold reasonably clear water for most of the week. Tides are where this week gets interesting: we move from weak, nearly diurnal exchanges early in the week into noticeably larger swings by the weekend, with Saturday and Sunday showing a high of +1.2 ft against a low of -0.4 ft — that's a 1.6-foot exchange producing strong tidal current through cuts and passes. Strongest current will come during those big Saturday and Sunday exchanges, with the bulk of the water moving in the early-morning and evening windows; if you're running a shallow-draft boat through the jetties or any natural pass, give yourself time to account for the push. Heat is the other story this week — highs touching 90°F by Thursday with overnight lows barely dipping to 81°F means surface water temperatures aren't getting any relief, so watch for midday thermals over the flats if you're running light gear on an open skiff. Afternoon storm chances linger Sunday and Monday, so keep an eye on the radar before you push offshore — the SSE swell that's building by mid-week will still be rolling if those cells kick up any wind ahead of them.
