As a fishing enthusiast, you’ve probably wondered whether it’s worth casting your line after a rainfall. It’s a question that has been debated for years among anglers, and yet no definitive answer has been established.

Some fishermen swear by wet weather, claiming that the rain brings fish close to the surface, while others believe that they should pack up and go home once the skies open up.

The truth is that the relationship between fish and rain is complex and multifaceted, with many factors contributing to whether or not biting will increase during and after a rainfall.

“Weather conditions, water temperature, atmospheric pressure fluctuations, and even the species of fish in question can all play a role in determining their feeding behavior,”

If you’re eager to discover the truth about fishing after rainfall, keep reading to learn more about how different environmental factors impact fish biting behavior, and what steps you can take to optimize your chances of success on your next angling expedition!

Understanding the Effects of Rain on Fish Behavior

Rain can be a major factor when it comes to fishing. It affects not only the water quality but also fish behavior. Knowing how rain influences fish activity will help you catch more fish and increase your chances of success.

The Importance of Knowing How Rain Affects Fish Behavior

Rain alters aquatic conditions in lakes, rivers, and ponds, which affects the behavior of fish dwelling within them. Consequently, anglers need to understand these changes if they want to adapt their fishing strategies accordingly and maximize their catch rate.

By learning about the impacts of rain on fish behavior, anglers become better equipped to predict what tactics to use during particular weather events. Knowledge of such effects makes angling more productive; giving enthusiasts an upper hand while casting their lines.

The Science Behind How Rain Affects Fish Behavior

“Rainwater from runoff carries organic matter into streams and lakes that feed microorganisms essential for sustaining fishes’ diets” – Dr. Mariah Meek, fisheries biologist at Penn State University

Firstly, significant rain increases the amount of dissolved oxygen in the water. During rainfall, water absorbs atmospheric oxygen and aerates the water column, making it easier for fish to breathe. This leads to increased feeding activities by surface-dwelling and near-surface fish species.

Secondly, heavy rainfall causes runoffs that wash away nutrients and minerals that have been accumulating on the bottom sediment of lakes and rivers. Such nutrient-rich waters improve fish food sources, triggering a sudden surge in fish population and distribution.

Rain is beneficial for fish because it improves the growth of overall productivity, which in turn improves both individual as well as population health.

How to Determine the Best Time to Fish After Rainfall

“After a heavy rain and cold front, the most productive time is typically 24-48 hours after water levels stop rising.” – Orvis Fly Fishing

The best fishing times during or after rainfall depend on various factors such as water temperature, flow rate, pressure, and fish location. However, some general rules can aid in predicting the best time to go fishing after rainy weather:

  • Fishing immediately after the storm might not be effective due to rapidly changing conditions.
  • Wait for at least 24 hours after the storm has stopped before resuming fishing activities.
  • A gradual decline in precipitation signifies better chances of catching fish.
  • Understand how different species behave under varying weather scenarios and adopt accordingly.

Knowing how rain affects fish behavior will help anglers achieve their desired results. Take into account the amount of rainfall, time elapsed after a rainy spell, along with the specific characteristics of the body of water and its inhabitants when planning your next successful angling excursion!

Factors That Affect Fish Biting After Rain

If you are an avid angler, chances are that you have heard the age-old question: do fish bite after rain? The answer is not straightforward since many factors influence fish feeding behavior. In this article, we will explore some of the most significant variables that affect fish biting after rain and make an informed conclusion.

Water Temperature and Oxygen Levels

The primary factor that affects fish biting after rain is water temperature and oxygen levels. Before a storm or during light precipitation, air pressure decreases, leading to reduced surface tension and increased oxygen levels in the water. This results in more active feeding among fish species such as bass, trout, and panfish. However, once heavy rains start, water temperatures can decrease drastically, driving fish towards deeper and warmer waters, where oxygen supply is plentiful.

In contrast, warm summer showers may not lead to any change in water temperatures and could produce favorable conditions for topwater fishing for predatory species like pike and musky. These species tend to come out from their hiding spots and hunt close to the surface when conditions favor them.

Water Clarity and Flow Rate

Rain has a profound impact on water clarity, which significantly influences fish feeding behavior. During or after rainfall, murky or debris-laden water makes it harder for fish to locate food. Consequently, fish may become less active, making it difficult to catch even with baited lures or live baits available to them.

Following a few hours or days after rain, streams and rivers clear up, increasing visibility and making it easier for species such as salmon and steelhead to spot prey. Flow rate also plays a role here; heavy rains generally increase river flow rates, creating new pools and eddies that attract fish with a fresh supply of food and oxygen.

“High water stresses fish out, sometimes even to the point where they stop feeding. But when things start dropping back down, especially when the water is clearing up, they’ll start moving around again,” says fly-fishing guide Bill Schiess.

The Type of Precipitation

It’s not just rain that impacts fishing behavior; different types of precipitation can alter aquatic conditions as well. For example, hailstorms could lead to higher turbidity levels, and snowmelt releases sediment into rivers and streams, affecting visibility somewhat similarly to rainfall. Thunderstorm fishing is a popular pastime since storms stir up insects such as mayfly, which leads to a feeding frenzy among various species.

If you’re planning a fishing trip after a storm, keep an eye on local weather forecasts and keep in mind the type of precipitation that occurred. You don’t want to miss a great day because the conditions were unfavorable for your target species.

Whether or not fish bite after rain depends on various factors such as water temperature, oxygen levels, clarity, flow rate, and the type of precipitation involved. Being knowledgeable about these variables can help improve your chances of success while fishing during inclement weather. Tight lines!

Best Fishing Techniques to Try After Rainfall

After a good rainfall, many anglers often find themselves questioning whether fish will be biting. The answer is that it depends on various factors such as water temperature, barometric pressure, and oxygen levels. However, there are several fishing techniques you can try after rain that could help improve your chances of catching fish.

Using Live Bait to Attract Fish

If you want to attract fish after rain, then using live bait is an excellent option. When the rain begins to fall, earthworms, crawfish, or other small creatures get washed into the river, becoming easy prey for fish. In these situations, using live bait that looks like natural prey can increase your chances of getting a bite.

You can use any small, natural baits like maggots, crickets, or minnows because they look like food in the water column. If you were curious about what to do with artificial baits after the rain, you should switch them out with some lively and real ones to mimic the prey movement inducing strikes from hungry predators. With this technique, make sure the hook placement is sturdy and secure so it doesn’t slip off too easily.

Using Lures to Mimic Prey Movement

Fishing lures are one of the most commonly used techniques for attracting fish after rainfall. There is something about shiny objects that can pique the interest of fish, especially if they mimic the movements of their normal prey. For instance, crankbaits can create vibrations that resemble shad swimming quickly away from predator fish. Spinnerbaits imitate small fishes coming up to breathe after being submerged underwater by creating quick turbulent waves which would lure predators nearby.

The key is finding the right type of lure that corresponds to the natural baitfish in your body of water. You can go with a gentle approach or aggressive one depending on how picky and carnivorous your target species is. As an angler, you should have several types of lures ready for different conditions like light or stained water.

Understanding the Importance of Retrieval Speed

Speed could be the most significant factor between getting skunked or catching fish after rainfall. The right retrieval speed increases the possibility of mimicking live bait movements that attract predator fish to bite. If they see their prey moving slowly, then it tends to be less appetizing as opposed to seeing it quick, bouncy, or erratic.

The ideal retrieval speed depends on many factors such as water temperature, depth, level of cloud cover, and especially targeted species preference. Most bass anglers report using a moderate tempo (varying speed) when fishing lures in cool-freshwater because fish aren’t always feeding aggressively. However, keeping an erratic jerking pace works great for smallmouth bass and walleye fishing during cloudy weather; these are signs when predators usually feed actively near the surface.

In Summary, if you want more success while fishing under rainy conditions, don’t give up hope! Follow these tips: use lively bait, mimic live movements with your choice of lure selection, and maintain appropriate retrieval speed based on current environmental cues that could boost catch rates. Good Luck!

Top 5 Fish Species That Bite Best After Rain


Bass is one of the most popular game species, and many anglers enjoy fishing for bass after rain showers. The best time to fish for bass after rain is when you can hear the sounds of water running from higher ground into the lake or river. During heavy rains, worms, bugs, and various insects are washed out of their habitat and drained directly into the water. Bass love these foods, so they get closer to the surface and start searching in shallow areas.

In addition to that, according to a study by North Carolina State University, it was found that smallmouth bass consume more prey during rainy periods compared to clear days because food items are often washed in, increasing their availability and leading to increased feeding activity during these times.


Rainy days can be an ideal fishing scenario when it comes to trout. Trout are cold-water creatures, but warm summer temperatures can heat up the rivers’ water that can make trout less active and stay under deep pools where there is cooler water, waiting for prey to pass them by. However, after a rain shower, everything changes, especially if the rain is relatively fierce. It will help cool down the water temperature and increase oxygen saturation levels, bringing trout close to the surface in search of food.

Australian Fishing Network advises anglers targeting trout after rain should try using bait such as live worms, mudeye grubs, soft plastics, and lures such as spinners or spoons.


After extreme rains, walleyes move upstream to nibble on smaller fish that have been pushed downstream due to the fast-flowing current. Walleyes prefer hunting once the sun has set, which makes them nocturnal hunters.

According to an article by In-Fisherman Magazine, rainfall can also shift walleyes into shallower water throughout the day. Walleye’s eyes are specially adapted to function best in low-light conditions, making it easy for them to hunt in shallow and slightly turbid water.


Catfish is a species that can thrive on cloudy days or even during light rain showers but heavy rains can wreak havoc as they cannot tolerate large fluctuations in water temperature and quality.

On how light rain affects catfish feeding habits Colby Crossland from Professional Catfishing Association says; “Catfish still bite well when there’s light rain because it cools off the water, along with providing oxygen,” he explains. “Plus, worms are often washed out of their homes after heavy rain, so you have more bait available.”


American Sport Fishing Association recommends fishing for crappie after rainy periods at depths between 8-16 feet, where water levels typically rise due to downpour and cover trees and brush piles – ideal habitats for this fish. Due to an increased food supply, crappies start biting harder during post-rain scenarios than pre-rain, with anglers using live bait like nightcrawlers, minnows alongside jigs, grubs and crankbaits having excellent chances of being successful.

Expert Tips to Maximize Your Catch After Rainy Days

After a rainy day, many fishermen wonder if it’s worth going fishing or if the fish will even bite. The good news is that fish are more active after rain and can be easier to catch if you know what to do. Here are some expert tips to help maximize your catch after rainy days:

Locating Fish with Electronic Fish Finders

An electronic fish finder is one of the most useful tools for locating fish after a heavy rainfall. These devices work by sending out sonar signals that bounce off objects in the water, including fish. The signals then return to the device, providing information about the depth and location of the fish.

If you have an electronic fish finder, use it to locate areas where fish may be congregated after a rainfall. Look for deeper pockets of water where fish might seek shelter from the turbulent surface waters. Additionally, focus on areas near structure, such as rock formations and fallen trees, which can provide cover for fish.

Here are some additional tips for using an electronic fish finder:

  • Look for tightly packed groups of fish, which indicate an active school.
  • Adjust the sensitivity and frequency of the device to get the best results.
  • Use side-scan mode to search larger areas quickly.

Adjusting Your Fishing Gear and Equipment

After a heavy rainfall, you may need to adjust your fishing gear and equipment to make sure you’re presenting your bait effectively. Here are some things to consider:

  • Bait – Consider using live bait like earthworms, minnows, or leeches. Freshwater fish tend to feed near the bottom after a rainfall, so use heavier weights to sink your bait quickly.
  • Rod and Reel – Choose a rod that is strong enough to handle larger fish as they may be active after rain. Also, adjust the tension on your reel to allow for more sensitivity when fishing in areas with debris or structure.
  • Fishing Line – After a rainfall, it’s common for rivers and streams to become murky. This can make it more difficult for fish to see your line or lure, so consider using colored or thicker line to increase visibility.

Choosing the Right Fishing Spot

The key to catching fish after rain is finding the right spot. Here are some things to consider:

  • Water Temperature – After a rainfall, cooler water temperatures can create ideal conditions for certain species of fish like trout. Focus on colder sections of the waterway where these fish might congregate.
  • Timing – Fish might not be immediately active after the rain has stopped, but wait an hour or two for the runoff to get into the local river systems. Then get yourself out there!
  • Spot Structure – While picking a good spot- focus near underwater logs, rocks, boulders and weed beds. Typically standing close to edges will help give you a better chance at catching multiple varieties of fish because small creatures such as bugs, shinners etc also collect, attracting other predatory fish.

By following these tips, you’ll be well on your way to maximizing your catch after rainy days. Remember that patience and persistence are key traits for successful fishermen, so don’t give up if you aren’t getting bites right away. Good luck and happy fishing!

Common Mistakes to Avoid When Fishing After Rain

Do fish bite after rain? The answer is yes, but only if you know the right techniques and avoid common mistakes. Here are some tips on how to make the most of a rainy fishing day:

Fishing in the Wrong Areas

One mistake many anglers make when fishing after rain is going to the wrong spots. Heavy rainfall can cause water runoff, which can change the water conditions drastically. Water flowing into lakes or rivers can bring in sediment that will reduce visibility and affect the oxygen levels, making it difficult for fish to see your bait and breath properly.

To avoid this problem, look for areas where there is less surface runoff, such as coves or deep pockets with more vegetation covering the banks. Fish will often hide under these areas during a rainstorm and be ready to feed once it has passed. Using a topographic map or asking local fishermen can help you identify the best places to cast your line.

Using the Wrong Fishing Techniques

Another mistake that people make when fishing in the rain is using the wrong bait and tackle. Wet weather can alter the behaviour of fish, changing what they eat and how they react to lures. Additionally, heavy cloud cover can make it harder for them to see air-borne insects, so you may have to use baits that mimic what they would naturally eat in low-light conditions.

Instead of using bright colours and noisy lures, try switching to slow-moving baits like worms or leeches. They will appear natural in cloudy conditions and attract fish looking for an easy meal. If you’re fly fishing, switch to streamer patterns that mimic small fish or nymphs at different depths. You’ll want to keep testing out different tactics till you find what works best.

Lastly, don’t forget to adjust the speed of your retrieve. Fish may be less aggressive after a rainstorm and take their time in inspecting baits before biting. You might want to slow down or pause between each jerk until you feel a tug on the line.

“One thing that has remained constant over my 25 years of guiding is that fish still have to eat, regardless of the weather.” – Nate LaPointe from Orvis Fly Fishing Blog

When fishing after rain, keep an open mind and stay optimistic. Each lake or river will present unique challenges, but knowing where to look and adjusting how you fish can make all the difference. Don’t let a little precipitation stop you from having a great day out on the water!
