Good morning, anglers—this is Artificial Lure, and here’s your boots-on-the-bank fishing report for Rio Grande, Texas, Saturday August 30, 2025. Sunrise was at 7:10 AM and sunset’s rolling in at 8:01 PM. We’ve got steamy late summer weather—early hours are mid-70s, warming up quick into the high 90s by mid-afternoon, so pack ample hydration and sunscreen. Scattered clouds will drift in and out, winds are light from the southeast around 7 mph, making for classic Valley morning conditions before heat builds.
Today’s tides: NOAA shows a high tide peaking around 5:04 AM at 5.84 feet, tapering to low at 10:10 AM, then rising again toward another high at 4:34 PM. If you’re chasing reds or specks, take advantage of that early-morning flood until about 8 AM, then shift tactics as water drops out to expose the mud flats and mangroves.
Fish activity on the Rio this week has been above average. Out by the river mouth and near Boca Chica flats, anglers have landed good numbers of slot reds, some pushing 28 inches. Plenty of speckled trout are showing on the edge of drop-offs, with a mix of keeper sizes, averaging 16 to 19 inches. Catfishers upriver near Brownsville are hauling blues and channels averaging 2 to 5 pounds, mostly taken on cut shad and doughbait. Down by the Island, flounder bites picked up on sandy transitions with numbers running small but steady, so keep those Carolina rigs handy.
Lurewise, this heat calls for **soft plastics in root beer or chartreuse**—paddle tails like 2-inch Bass Assassins and 4-inch Saltwater Gulp Shrimp are top producers on slow retrieves just above the grass. If the tide’s pushing, switch to a 1/8 oz jig head for better control. Anglers working topwater early found success with **Super Spooks and Skitterwalks**—steady pops near reeds will draw strikes from trout and ambitious redfish. When it comes to bait, fresh-dead shrimp is king for numbers, and live mullet are a proven choice for targeting bigger reds and snook, especially during those rushes after sunrise.
Recent catches along the levee and near the main channel include black drum, with several bags going over a dozen fish each. Carp anglers report good action with bread balls upriver, noting multiple 10-pound-plus fish landed near the flood control gates. Night fishing on the lower Rio is yielding some solid gar action—anchored cut bait rigs are getting hit by four-foot longnose and spotted gar as dusk drops.
For hot spots, locals are swearing by the area around **Boca Chica Flats**, especially near the mangrove lines during outgoing tide, and the **Old Brownsville Weir** for consistent catfishing all week. For a multispecies bite, hit the confluence at **Las Palomas Wildlife Refuge**; lively bait and lures have produced mixed bags of reds, drum, and some decent trout on cooler mornings.
Don’t forget: with Labor Day looming, Texas Game Wardens will be out in force. Wear your life jacket, know the water safety rules, and make sure your registration tags are up to date if you’re boating. Stay safe and clean up after yourself—leave the water prettier than you found it.
