S8, Ep 48: Summer Heat Strategies: Captain Brian Shumaker's Smallmouth Tips

Episode Overview

A scorching Fourth of July heat wave is bearing down on Central Pennsylvania, and the Susquehanna and Juniata rivers are about to test every smallmouth angler's heat tolerance. On this Pennsylvania Smallmouth Report from The Articulate Fly fly fishing podcast, host Marvin Cash checks in with Captain Brian Shumaker of Susquehanna River Guides for a candid, safety-first conversation about fishing smallmouth bass through triple-digit conditions.

With water temperatures pushing into the 90s and a 101-degree forecast on the horizon, Brian breaks down how heat affects both the bite and angler safety on his home waters. The Juniata offers some bankside shade thanks to its narrower channel, while the three-quarter-mile-wide Susquehanna leaves anglers largely exposed. Brian and Marvin trade practical advice on hydration, sun protection and timing strategy, then dig into the tactical adjustments that keep smallmouth on the line when conditions turn brutal. That includes a hard pivot to tropical fly lines once standard fly lines start going soupy in the heat, plus a shade-line and riffle-focused approach using poppers, crayfish patterns and baitfish imitations like the Murdich Minnow. The two also debate the merits of an early-morning session versus a late-afternoon-into-dark float, with Brian making a clear case for the latter. It is a short, practical episode built around one core message: protect yourself first, then adapt your tactics to the heat.

Key Takeaways

• How to stay hydrated and avoid heat-related risks while fishing smallmouth in 100-plus-degree conditions
• Why tropical fly lines outperform standard fly lines once summer heat sets in
• When to fish for the best results during a heat wave: a late-afternoon-into-dark session over an early-morning start
• How to use shade lines and oxygenated riffles to locate active smallmouth during the hottest part of the day
• Which fly patterns to throw when water temperatures push into the 90s, including poppers, crayfish patterns and baitfish imitations like the Murdich Minnow
• Why caffeine and alcohol should be avoided in favor of water and sports drinks on extreme-heat fishing days

Techniques & Gear Covered

Brian outlines a shade-line and riffle-focused approach for fishing smallmouth through extreme summer heat, working topwater poppers along shaded banks and rolling crayfish patterns through riffles where oxygen levels run higher. For subsurface presentations, he reaches for baitfish imitations including the Murdich Minnow and Shimmering Minnow patterns. The single biggest gear adjustment for this stretch of summer is the fly line itself: Brian made the switch to tropical lines years ago, since standard fly lines turn soft and sticky once water and air temperatures climb to summer levels. On the sun-protection side, the conversation covers sun hoodies with built-in buff gaiters, quick-dry SPF nylon pants and wide-brim hats as practical defenses against extended midday exposure on open water like the Susquehanna.

Locations & Species

This report centers on the Susquehanna and Juniata rivers in Central Pennsylvania, Brian's primary guide waters out of Susquehanna River Guides. Smallmouth bass are the target species throughout. The conversation is framed around peak summer heat conditions heading into the Fourth of July, with water temperatures pushing into the 90s and air temperatures forecast to hit 101 degrees. The Juniata's narrower channel and tree-lined banks provide more shade options than the much wider Susquehanna, where shade is largely limited to the banks themselves, making shade-line and riffle strategy especially important on the bigger river during this stretch.

FAQ / Key Questions AnsweredWhy do tropical fly lines work better than standard fly lines for summer smallmouth fishing?

Standard fly lines turn soft and sticky as water and air temperatures climb to summer levels, making them difficult to cast and fish effectively. Tropical lines are built to hold their stiffness and performance in high heat, which is why Brian made the permanent switch starting around July and continuing through early September.

How can anglers stay safe while fly fishing in extreme heat?

Brian and Marvin recommend drinking water at least every 30 to 45 minutes throughout the day, and avoiding both alcohol and caffeine since both contribute to dehydration. Full sun coverage matters too, including 50 SPF sunscreen, sun hoodies with built-in gaiters, quick-dry SPF clothing and a wide-brim hat, even when fishing in or near shade.

What time of day is best for fishing smallmouth bass during a heat wave?

Brian prefers getting on the water around 5 p.m. and fishing until dark, rather than starting at first light. A late-afternoon start avoids the pre-dawn shuttle logistics of an early session while still delivering enough usable light to fish productively until around 9 or 9:15 p.m.

What fly patterns work best for smallmouth bass when water temperatures push into the 90s?

Topwater poppers worked along shade lines remain effective, and crayfish patterns produce well when fished through oxygenated riffles. For baitfish presentations, Brian reaches for the Murdich Minnow and Shimmering Minnow patterns.

How can anglers find productive water on a wide river like the Susquehanna during peak summer heat?

Since the three-quarter-mile-wide Susquehanna offers little overhead shade beyond its banks, Brian focuses on fishing the available shade lines along the banks combined with oxygenated riffle sections, rather than expecting shade relief across the open channel the way a narrower river like the Juniata provides.
