COASTAL FORECAST: Lower Coast – August 2018

August Rocks

I T’S BEEN A TYPICAL South Texas summer. It’s hot, the winds have either disappeared altogether or make you feel like you’re in a bamboo steamer.

Laguna Madre water temperature has been in the mid-80s since mid-May, and trout and redfish have disappeared from the flats. There doesn’t seem much an angler can do in August except get up at early thirty to try and get a few fish and head back to the dock for the teeth of the day. August fishing can be tough sometimes.

Fishermen can take heart, however. The jetty systems of both Brazos Santiago and Mansfield passes provide some excellent (and sometimes better) fishing for a variety of fish, including some that are highly desirable among even the most discriminating anglers. 

Some of the most underrated summer fishing in South Texas takes place along both sides of the Brazos Santiago Jetties. These jetties book-end the pass by the same name, which feeds in and out of Lower Laguna Madre.

These jetty systems are accessible from land—the north jetties from South Padre Island, and the south jetties from Brownsville via SH 4, then left onto Brazos Island (known locally as Boca Chica Beach).

The jetties offer excellent fishing for everything from the four parts of the “Texas Slam” (trout, redfish, flounder, and snook), mangrove snapper, Spanish mackerel, tarpon, and even kingfish for the properly equipped.

Certainly, the most sought-after fish are speckled trout and redfish. Both can be caught from the jetties on the same trip. However, different techniques are called for.

Speckled trout usually will hold closer to the rocks and cruise up and down the gut that runs parallel to the jetties. This is especially true on the north jetties, where prevailing currents create gentler eddies and currents that push water and bait against the surf-side of the rocks on an outgoing tide. Redfish will prowl the surf away from the jetties and in the guts that intersect them.

An incoming tide sends fresh water in from the Gulf to lay swells down, making early mornings magical off the rocks. A fisherman can do well throwing live bait under a popping cork near the rocks for trout and mangrove snappers, which almost become a nuisance with their abundance. A Carolina rig out in the surf for redfish is also good. The bait bucket, however, isn’t necessary.

All you need is a box filled with chugging topwaters such as the Storm Chug Bug, Pop-A-Dog,or similar such poppers, a couple of pink/polka-dot Rat-L-Traps, a ½ silver spoon or two, and a collection of your favorite plastic tails in red/white, or chartreuse patterns and some 1/8 ounce jigheads (the lighter heads are less apt to snag up). 

If the wind is straight from the south, you can still fling topwaters parallel to the rocks. In fact, the trout seem a little more aggressive in the more active water.

Start an early morning expedition on the jetties by casting back towards the corner where the rocks meet the beach and work the lure back along the bottom. Trout should be there, but a few big flounders may also be waiting in ambush. From those casts, expand out into the guts and cast parallel to the beach to see whether there are redfish.

It doesn’t hurt to take a few wire leaders in your tackle box. This time of year, schools of Spanish mackerel tear into bait balls in front of the jetties. They aren’t discriminating and can clean you out of tackle in a hurry.

On the South jetties, the surf is a bit rougher, and the rocks are not laid as smoothly, but the presence of snook in the suds more than makes up for the tougher work. These fish will also attack the same trout and redfish lures with abandon., Plus, they offer some gill-rattling jumps for your thrills. 

The question always comes up about the sort of tackle needed for the jetties. Honestly, your traditional inshore 10- to 12-pound tackle is enough, but if you hook into a big red or snook, you are going to be in trouble. Upping slightly with 14- to 17-pound tackle is a safer bet to handle just about anything that swims the suds around the pink granite. Also, it gives you a little more power in reserve if Mister Big comes calling. My preferred rig is a 7½-foot medium action casting rod with a Curado 300-e, loaded with 10/40 Power Pro braid. This outfit will tackle pretty much any fish you might run into on the rocks, unless a 150 pound tarpon grabs your plug; then, all bets are off. 

If you feel ambitious, walk all the way to the end of the jetties to take a shot at a kingfish or tarpon. Tarpon prowl the currents and eddies on the channel side of the jetties when the tide is running.

Mullet-imitators such as a large Rapala, Bomber Long A, or a Berkley Power Mullet are the best bets to get a poon’s attention. Fly fishermen can use a large Tarpon Bunny or Chicken Feather-type fly on an 8- or 9-weight fly rod.

Calm days bring blue water right up into the rocks, and kingfish follow bait into casting range. Use a Magnum Rat-L-Trap in Chrome/blue or a fresh ribbonfish on a classic kingfish rig. Large menhaden (pogies) are best if you can get some that are fresh. Upgrade to a surf rod and high-capacity reel.

You never know what may show up and rock your world.
