Ryan Harrington | How Barometric Pressure Affects Fish Behavior | Tom Rowland Podcast Ep. 878

Captain Ryan Harrington, a fishing guide who spends over 320 days per year on the water, reveals how barometric pressure affects fish behavior and shares his proven strategies for catching fish in both high and low pressure conditions. Most anglers know the old advice about fishing before a storm, but Ryan breaks down the actual science behind why fish behave differently based on atmospheric pressure—and more importantly, how to adjust your tactics to catch fish whether it's a bluebird day or storm clouds are rolling in. If you've ever wondered why the fish were biting like crazy one day and completely shut down the next despite seemingly perfect conditions, this episode will change how you approach every fishing trip.

The Pizza on the Couch Analogy That Makes Barometric Pressure Click

Ryan doesn't just explain the technical side of barometric pressure—he makes it relatable with an analogy that every angler can understand. He compares high pressure conditions to eating an entire pizza and sinking into your couch cushions with your belly on the floor. You're full, you can't move, you're not hungry. That's exactly what's happening to fish when that beautiful bluebird sky rolls in after a storm passes. On the flip side, low pressure makes fish feel light on their toes, suspended higher in the water column and ready to eat again and again. Ryan has witnessed this phenomenon firsthand, watching snook behavior change dramatically based on atmospheric conditions. The way he breaks down complex meteorological concepts into simple, memorable comparisons makes this information immediately actionable for any angler. Ryan's full explanation of how fish respond to pressure changes starts at the beginning of the episode.

Why Beautiful Days Can Mean Slow Fishing (And What to Do About It)

Here's something that goes against everything most anglers assume: those gorgeous, cloudless, calm days that everyone wants to spend on the water? Those are often the worst fishing days. Ryan explains why high pressure—which creates those perfect bluebird conditions—pushes fish down and makes them inactive. He's seen snook with their bellies literally rubbing the sand bottom in two feet of water during high pressure periods. But Ryan doesn't just identify the problem; he provides the solution. His approach to high pressure fishing involves three key adjustments: go lower in the water column, slow everything down, and consider using smaller presentations or even cut bait. Instead of working topwater or fast-moving lures, Ryan suggests putting out a cut bait, placing the rod in a holder, and simply waiting. You might not catch 100 fish, but you will catch fish if you adjust your tactics. The complete strategy for fishing high pressure days starts early in the conversation.

How to Capitalize on Low Pressure Feeding Frenzies

When storm clouds roll in and the pressure drops, Ryan describes conditions where fish will literally eat anything you throw at them. Low pressure raises fish up in the water column, and even after they eat a bait, they still feel light and ready to feed again. These are the days when you can bring your kids out and catch 100 fish, when fish are chewing on the bottom of the boat, when nothing you do seems wrong. Ryan's advice for these conditions? Have fun. Throw whatever you want. The fish are going to cooperate. But understanding why this happens—and being able to recognize low pressure conditions when you see cloudy skies before a storm—gives you the confidence to get on the water when other anglers might stay home because it doesn't look "nice" outside. Ryan's spent enough time observing fish to know that those cloudy, pre-storm days are when the magic happens. Ryan's breakdown of low pressure fishing opportunities is covered throughout the episode.

The Lower, Slower, Smaller Rule for Tough Conditions

Ryan distills his high pressure strategy into three simple words that any angler can remember: lower, slower, and smaller. Whether you're fishing with artificial lures or live bait, these three adjustments will help you catch fish even when conditions aren't ideal. Fish closer to the bottom instead of working the surface or mid-column. Slow down your retrieve or use stationary presentations. Consider downsizing your bait or lure. Ryan specifically mentions using cut bait and dead baits during high pressure, putting them in rod holders and waiting patiently. This is the opposite of the run-and-gun approach that works during low pressure, but it's what the conditions demand. The beauty of Ryan's system is its simplicity—you don't need fancy equipment or complex techniques. You just need to understand what the fish are experiencing and adjust accordingly. The complete lower, slower, smaller strategy is explained in detail during the episode.

Final Thoughts from Tom

I love when guests can take something that sounds complicated—like barometric pressure—and make it immediately useful for everyday anglers. Ryan's been on the water more than 320 days a year, and that experience shows in how clearly he explains what's actually happening below the surface. The pizza analogy is something you'll remember next time you're looking at a forecast.

What really stands out is how Ryan doesn't just identify the problem of high pressure fishing. He gives you the exact solution: lower, slower, smaller. That's something you can apply immediately on your next trip. And understanding that those gorgeous bluebird days are often the toughest fishing days? That's counterintuitive information that changes how you plan your fishing schedule.

This is a short How 2 Tuesday episode, but it's packed with actionable information. If you've ever been frustrated by slow fishing on what seemed like a perfect day, or if you want to understand how to adjust your tactics based on weather conditions, listen to the whole thing. Ryan keeps it simple and gives you tools you can use on your very next fishing trip.
