7 Powerful Reasons Why Do You Catch More Fish in the Rain

1. Decreased Light Penetration

Rain creates overcast conditions and ripples on the water surface, reducing light penetration. This natural dimming effect makes fish feel more secure and willing to venture into shallower waters to feed. Additionally, the reduced visibility helps protect them from predators, leading to more confident feeding behavior. Many fish species, particularly predatory ones like bass and pike, become more active hunters under these conditions.

2. Increased Oxygen Levels

When rain falls, it creates surface agitation and introduces fresh, oxygen-rich water into the system. This process:

Increases dissolved oxygen content
Improves fish metabolism and energy levels
Stimulates more active feeding behavior
Creates better conditions for aquatic life

Rainfall Intensity	Oxygen Increase	Fish Activity Level
Light Rain	5-10%	Moderate Increase
Moderate Rain	10-20%	Significant Increase
Heavy Rain	20-30%	Very High

3. Food Sources Get Washed Into Water

Rainfall creates runoff that carries various food sources into the water:

Insects and terrestrial invertebrates
Seeds and organic matter
Small creatures from shorelines
Nutrients that attract baitfish

This influx of food triggers a feeding frenzy as fish take advantage of the abundant food sources.

4. Barometric Pressure Changes

The falling barometric pressure that typically precedes and accompanies rain has a significant effect on fish behavior:

Reduces pressure on fish’s internal air bladders
Makes them more comfortable moving and feeding
Triggers natural feeding instincts
Creates more aggressive feeding patterns

5. Water Temperature Regulation

Rain can help regulate water temperature, particularly during warmer months:

Cooler rainwater mixes with warmer surface water
Creates comfortable conditions for fish
Encourages movement between different water depths
Stimulates feeding activity in temperature-sensitive species

6. Reduced Visibility Works in Anglers’ Favor

Rain creates advantageous conditions for anglers:

Fish are less likely to spot fishing lines
Lures appear more natural in cloudy water
Fish feel more secure and less cautious
Allows for closer approaches to fishing spots

7. Natural Camouflage of Sound and Movement

Rain provides natural camouflage for anglers.

Rain drops mask boat or walking sounds
Surface disturbance conceals movement
Fish are less spooked by human presence
Allows for more aggressive fishing techniques

Impact on Different Water Bodies

Whether you are fishing in still waters like lakes and ponds, flowing rivers and streams, or coastal areas like estuaries and bays, rain can have major, different consequences. This is a discussion of how rainfall affects these several kinds of water bodies and how you could modify your fishing methods in response.

Lakes and Ponds

Lakes and ponds are still waters that react more slowly to changes, but rainfall can still cause important shifts in fish behavior and feeding patterns.

Increased Nutrients from Runoff: Runoff brought on by rain typically transports minerals, broken down organic debris, and silt into the river. A bloom in plankton and other microscopic organisms resulting from this draws baitfish. Predatory fish follow the gathering tiny fish, generating feeding sites along the lake’s or pond’s edges or near the surface.
Changes in Water Clarity: Rain can muddy the water by bringing particles including silt, trash, and other contaminants. While this will lessen visibility for anglers and fish, it also means that fish will rely more on their other senses—that of lateral line or sense of smell. To assist fish find your bait, use bigger lures or noisy baits—such as spinnerbaits or rattling crankbaits.
Formation of Thermal Layers: Rain can cause stratification in still waters, where cooler rainwater sits on top of warmer water. This creates thermal layers, with fish either remaining in warmer, deeper areas or moving to the cooler surface layers if the rain tempers the heat. Pay attention to temperature shifts and adapt your fishing depth accordingly. Fish may move into the upper layers if it’s not too cold or seek the more stable temperatures deeper down.
Creation of Feeding Zones Near Runoff Areas: The influx of nutrients and food sources near runoff areas creates productive feeding zones. Fish gather in these places to eat little creatures carried in by the rain. Search for inlets, creek mouths, or places where water finds its way into the lake or pond since these zones are sometimes bursting with fish.

Rivers and Streams

Rivers and streams are flowing bodies of water; rainfall has more dramatic effects on water flow, temperature, and food availability.

Increased Water Flow and Current: Rivers and streams see a major rise in flow following rain, which makes fishing from the shore or a boat more difficult. To escape the greater flow, fish in these waters could migrate to deeper pools or more sheltered sections. Adjust by using heavier weights or bottom-dwelling lures to keep your bait in the strike zone. Also, consider casting into eddies or areas with slower current.
Changes in Water Color and Turbidity: Increased turbidity results from rain washing organic materials, trash, and silt into flowing rivers. Should the water turn discoloured, fishing becomes more difficult. It can, however, also lead to circumstances whereby fish rely more on their other senses—that of sound and vibration. To draw fish in muddy waters, choose bigger, noisier lures as crankbaits, spinners, or jigs that produce vibrations and rattles.
Displacement of Food Sources: Rain can dislodge small fish, insects, and other food sources from their usual spots, forcing fish to adapt and search for new food. These displaced food sources often concentrate near obstacles like rocks, fallen trees, or river bends. Cast near these structures, where fish are likely hiding or waiting to ambush prey.
Formation of New Feeding Areas: New feeding sites in rivers and streams can be produced by the higher flow and dislodged food. Look for locations like pools, slack water, and eddies where water flow slows down or veers direction. Fish find these regions ideal for hunting since they provide protection from the strong flow and enough of food even.

Coastal Waters

Rain has a noticeable impact on saltwater fishing, especially in estuarine environments where freshwater mixes with seawater. These areas can change significantly during rainfall.

Salinity Changes in Estuaries: Precipitation diminishes the salinity levels in coastal waters, particularly within estuarine environments where freshwater converges with seawater. This alteration in salinity can influence ichthyological behavior, as species that are habituated to specific salt concentrations may migrate to alternative regions where environmental conditions are more stable. It may cause certain species, like striped bass or redfish, to seek shelter in fresher areas. Watch for changes in the water’s salinity levels and adjust your targeting to these species’ preferences.
Formation of Temperature Breaks: Rainwater is often cooler than the surrounding seawater, especially in warmer months. When rainwater enters the ocean, it can create a temperature break on the surface, where the cooler water meets warmer, deeper water. Fish are often attracted to these breaks as they bring cooler temperatures and a variety of food sources. Topwater lures or slow trolling along these temperature gradients can be highly productive.
Creation of Baitfish Congregations: Rainwater brings nutrients into coastal waters, stimulating plankton and small organisms that attract baitfish. Larger predatory fish thus pursue the baitfish into these nutrient-rich areas. Search for baitfish schools either close to the surface or in places where fresh water enters the estuary or bay. Larger fish like flounders, sea trout, or tarpon find hot sites in these places.
Changes in Tidal Patterns: Rain can affect tide patterns, particularly in cases when heavy rain alters river flow. Rain’s runoff can speed water in and out of estuaries or coastal bays, changing feeding and movement patterns for both predators and prey. Pay attention to tidal schedules and note how rainfall is affecting water levels. Fish may be more active during unusual tidal shifts or in the hours following a heavy downpour.

Fish Species Response to Rain

Warm Water Species

Species	Rain Response	Best Rainy Conditions
Bass	Very active	Light to moderate rain
Catfish	Highly active	Heavy rain, increased current
Carp	More active	Steady rain, cloudy conditions

Cold Water Species

Species	Rain Response	Best Rainy Conditions
Trout	Moderately active	Light rain, stable temperature
Salmon	Very active	Steady rain, cooler temperatures
Pike	Active	Overcast with light rain

Best Fishing Techniques for Rainy Conditions

Lure Selection

Rain can alter the visibility, water movement, and feeding patterns of fish, meaning your lure selection needs to be tailored to these changes:

Darker Colors for Reduced Visibility: In rainy conditions, water often becomes murky, making it harder for fish to see. Even in muddy water, dark-colored lures—black, purple, or dark green—stand out more successfully in low-visibility circumstances. Predatory fish that depend on their sense of sight can be drawn in part by these hues.
Larger Profiles for Increased Vibration: To make up for the reduced visibility and help fish track your lure, opt for larger-profile baits. Fish can locate these lures even in limited visibility since they produce more vibration in the water that they can feel through their lateral lines.
Noisy Lures for Murky Water: Use noisy or rattling lures in cases when rain has made the water muddy. Fish can be drawn in from a distance using built-in noise generators found in rattles or spinners. To produce sound waves that draw fish, topwater lures with rattles or lipless crankbaits are quite effective.
Scented Baits for Better Attraction: Fish often find food in low-visibility settings by depending on their sense of smell. To make scented baits—soft plastics or live bait—more appealing, use powerful smells releasing agents. To further appeal your lures, you can also attach scent attractants to them.

Presentation Adjustments

Changes in the environment during rain will affect how fish behave and where they are located. You need to adjust your presentation techniques to match these shifts:

Water Clarity Changes: As rain pours into bodies of water, it often causes turbidity. To adapt, slow down your retrieve speed to give fish more time to detect your bait. Additionally, opt for larger lures with more action to make them more noticeable in the murky water.
Current Strength: Rain can increase water flow, especially in rivers and streams. To keep the bait in the strike zone and retain control in faster-moving currents, you could have to utilize more simplified lures or heavier weights. For fast-moving water, good options are jerkbaits or crankbaits with a decent sink rate.
Fish Activity Levels: Rain can make fish more active, particularly in pre-spawn or feeding periods, or more lethargic when the weather turns cooler. If you notice fish are actively feeding, go for a faster retrieve and erratic action. If fish are more sluggish, slow down and focus on dragging lures along the bottom or presenting them in a subtle, enticing way.
Depth Variations: Rain can affect water temperatures and the positioning of fish in the water column. After heavy rain, fish may move to deeper water to seek stability in temperature. You may need to adjust your bait to deeper depths, either by using heavier jigs or bottom-bouncing techniques to stay within the strike zone.

Location Strategies

Rain influences where fish will congregate, and finding the right spots is key to a successful outing. Here are some prime areas to focus on:

Runoff Points: Many times, rain causes runoff from neighboring ground into rivers, lakes, or ponds. These nutrient-dense habitats draw baitfish, which draw predatory fish in turn. Search rivers, streams, or inlets where precipitation is entering the main body of water. These places sometimes become hotspots both during and following rain.
Protected Coves: During a storm, fish often seek shelter in more protected areas like coves, bays, or sheltered shorelines. These spots offer calm water compared to exposed open areas, making it easier for fish to feed. Look for shallow areas with cover (like fallen trees or submerged vegetation) where fish can stay safe and feed.
Structure Edges: Fish tend to congregate near structures that offer cover and a break from the current, especially during rainy periods. Areas around submerged rocks, fallen trees, or sunken vegetation become prime spots for predatory fish. Cast your lures near structure edges, where fish are likely hiding and waiting to ambush prey.
Current Breaks: In areas where rain increases water flow, fish often seek out current breaks. These can be places where the water flow slows, such as behind rocks, points, or ledges. Fish use these breaks as resting areas, where they can easily ambush baitfish swept by the current. Look for areas where the water transitions from fast to slow-moving, as fish will often hang around these zones.

Safety Considerations

Weather Monitoring

Maintaining personal safety and safeguarding your equipment depend on you being informed and ready for different fishing circumstances. Staying safe requires the following:

Checking Weather Forecasts: Always begin your fishing excursion by reviewing the most recent weather prediction, especially in a region where fast swings in temperature are common. This includes looking out for:
- Temperature shifts that may influence fish behavior or cause hazardous conditions.
- Thunderstorms or heavy rain that could make the waters dangerous or affect visibility.
- Wind speed to determine if conditions might become dangerous on the water (especially for boaters).
Monitoring Lightning Activity: Among the most serious hazards during thunderstorms is lightning. Overwater lightning strikes are more common, hence fishing poles can function as conductors. Always take these precautions:
- Get off the water immediately if you hear thunder or see lightning in the distance.
- Seek shelter in a sturdy building or vehicle—never remain in open water or under trees.
Understanding Wind Patterns: Wind conditions can drastically change the fishing experience and the safety of your outing:
- Strong winds can make boating dangerous, create waves, or make fishing from shore harder.
- Fish movement and habitat preferences can be influenced by wind direction, but it’s important to steer clear of locations where gusts might overwhelm tiny boats or blow trash onto the shore.
Recognizing Dangerous Conditions: Even if you’re not a weather expert, you should be able to recognize the following warning signs:
- Darkening skies and rapidly changing cloud formations.
- Sudden drops in temperature signaling the approach of storms or cold fronts.
- Heavy or rapid rain can lead to flash flooding or swift changes in water conditions.

Equipment Protection

Ensuring both your safety and the protection of your equipment is just as important as monitoring the weather. Here’s how to safeguard your gear:

Waterproof Clothing: Regardless of the season, waterproof clothing is essential for staying dry and warm. Invest in quality:
- Jackets and pants to shield from rain, wind, or water splashes.
- Hats or rain gear to protect your head and neck, especially during storms.
Electronics Protection: Modern fishing trips often involve the use of electronics, such as GPS devices, fish finders, or mobile phones. Water, humidity, or even rain can damage these devices, so:
- Use waterproof bags or cases for electronics when not in use.
- Always have extra waterproof batteries or charging options, as wet conditions can deplete battery life.
- If you use electronics in boats, make sure they are firmly installed to avoid water damage in unplanned splashes or storms.
Non-slip Footwear: Common surrounding water are wet, slick surfaces, hence slips can cause accidents. Choose correct shoes to protect yourself.
- Non-slip boots or shoes designed for wet environments will reduce the risk of slipping on wet rocks, docks, or slippery boat decks.
- Water-resistant materials for shoes will help keep your feet dry and warm, providing both comfort and protection.
Emergency Equipment: Always keep emergency gear on available when fishing, particularly in isolated areas or during hazardous weather:
- First aid kit with essentials like bandages, antiseptic wipes, and any necessary personal medications.
- Flare or signaling device in case you get stranded on the water or need to alert others to your location.
- Life jackets or PFDs (Personal Flotation Devices) for everyone on board, including any children or pets, regardless of how experienced you are.
- Whistle or horn to signal if you’re in distress.
- Multi-tool or knife for quick repairs or addressing emergencies.
- Flashlight or headlamp to help during dusk or nighttime fishing trips.

Seasonal Variations

Spring Rain Fishing

Spring rains create prime conditions for fishing, especially just before the spawning season. Here’s how:

Pre-spawn feeding activity: Fish, particularly bass, boost their feeding activity in readiness for spawning as water temperatures start to climb. Fish are more active and simpler to capture since the nutrient-rich runoff from the rain offers a plenty of food.
Increased water temperatures: Particularly in later April, the rains offer warmth. With increasing temperature, fish get more active; they also frequently gather in shallow waters close to spawning sites.
Nutrient-rich runoff: Nutrients including minerals and organic debris wash into lakes and rivers by spring rain. Plankton and algae grow as a result, drawing baitfish in turn. Larger fish trail the baitfish as they migrate.
Active baitfish movement: The rains often disrupt the stillness of water, causing baitfish to scatter or move toward areas with stronger currents. Predatory fish follow these schools, making for an excellent fishing opportunity.

Summer Rain Patterns

Summer rains have a different influence on fishing. The rain often serves as a relief to fish and can create new fishing strategies:

Cooling effect on warm waters: For fish, water temperatures in hot summer months could become intolerable. A quick downpour might chill the surface waters and increase their appeal to fish for approaching their surface.
Increased oxygen levels: Rain gives the water oxygen, which is vital in the summer when oxygen levels can decline particularly in deeper sections. Fish can be driven into regions where they can feed more readily by higher oxygen levels.
Storm-front feeding: Fish, particularly predatory species like bass and walleye, become more active before and after a summer storm. The dramatic change in weather can signal fish to feed more aggressively, often providing great catches.
Pattern changes: Summer rains can disrupt typical fishing patterns by stirring up water clarity and changing the water flow. This may force fish to relocate to more favorable habitats, and anglers need to adjust their tactics accordingly, such as using scent lures or deeper-running baits.

Fall Rain Impact

As temperatures begin to drop and days shorten, fall rains create a unique environment for fishing:

Migration patterns: In fall, many species of fish (e.g., salmon, striped bass, and trout) start migrating towards deeper waters or towards spawning grounds. The rain encourages this movement, providing anglers with opportunities to target migrating schools.
Feeding intensity: Fall rains, combined with the cooler weather, ramp up fish’s feeding intensity. Fish, particularly those that are preparing for winter, become more aggressive in feeding as they store up for the colder months.
Water temperature stability: Fall rains help maintain water temperature stability. The cooler rain helps slow down the warming of water that happens during the day, keeping the temperature more consistent. Stable water temperature helps maintain fish activity levels, especially in species sensitive to drastic shifts.
Baitfish movement: As baitfish migrate or adapt to changing conditions, they often move to different depths or into shallow waters. Larger fish follow these movements, which creates hotspots for anglers who know where to look for these changes.

Advanced Fishing Strategies

Reading Weather Patterns

Understanding weather dynamics helps predict fish behavior and plan fishing trips effectively:

Front Movements: Fish are often more active before a cold front due to falling pressure, while activity may slow after its passage. Warm fronts can trigger feeding as they stabilize conditions and slightly warm the water.
Pressure Changes: Fish sense barometric pressure shifts. Low pressure (rainy conditions) can encourage feeding as it stirs the water and increases oxygen levels, while high pressure (clear skies) often makes fish less active.
Wind Direction: Wind can push surface food and plankton, attracting baitfish and predators to windward shores or points. Fishing where the wind concentrates food increases chances of success.
Cloud Cover Patterns: Overcast skies reduce light penetration, making fish feel more secure and increasing their activity. Fish are likely to feed more aggressively under consistent cloud cover.

Adapting to Water Conditions

Rain can significantly alter water characteristics, so adjusting techniques is key:

Water Clarity Changes: Rain can muddy waters, reducing visibility. Bright or contrasting lures (e.g., chartreuse, white, or UV-reflective) and lures with vibrations (e.g., spinnerbaits) are effective in turbid conditions. In clear water, natural-colored lures or live bait are better.
Current Variations: Rain often strengthens currents, especially in rivers and streams. Heavier sinkers, jig heads, or weighted rigs may be needed to maintain control. Cast upstream and let your bait drift naturally with the current for a lifelike presentation.
Temperature Fluctuations: Particularly in summer, rain can cool top water, driving fish to shallower depths with comfortable temperatures and high oxygen levels. Fish might, on the other hand, migrate to deeper, more stable water in colder months.
Depth Adjustments: Rain often redistributes fish. Adjust the depth of your bait or lures accordingly, targeting mid-depths or the bottom depending on species and conditions. Using depth finders or sonar can help locate fish.

Equipment Considerations

Rod and Reel Selection

When fishing in the rain, choosing the right gear is essential to ensure durability and performance.

Sealed Drag Systems: Keeps the reel running smoothly in damp circumstances by preventing water from getting inside.
Weather-Resistant Materials: Made of corrosion-resistant materials like graphite, stainless steel, or anodized aluminum, rods and reels stop moisture-related damage.
Appropriate Action: To manage perhaps larger rain-induced currents or energetic fish behavior, use rods with the appropriate action—that of medium-speed or rapid.
Reliable components: Opt for quality guides, handles, and reel seats that withstand exposure to rain without compromising performance.

Line and Terminal Tackle

Rain impacts water clarity and current strength, so adjustments to your line and tackle are vital:

Visibility Conditions: Use lines with low visibility in clear water, such as fluorocarbon, or high-visibility braided lines in murky conditions for better strike detection.
Current Strength: Increase the weight of sinkers or use heavier jig heads to maintain control in stronger currents caused by rainfall.
Target Species: Choose hooks, lures, and bait suited for the behavior and feeding patterns of your target fish species during rainy conditions.
Presentation Needs: Adjust lure colors and action to match the water’s appearance; brighter or more reflective lures may work better in low-light or murky rain-affected water.

Common FAQs About Fishing in the Rain

Does rain increase fishing?

Rain can increase fishing success under certain conditions. It oxygenates the water, attracting fish closer to the surface, and washes insects into rivers and lakes, creating feeding opportunities. However, heavy rain may muddy the water, reducing visibility for fish. Timing and location are key to taking advantage of rainy weather.

What weather do fish bite best in?

Fish bite best during mild, overcast weather with stable conditions. Cloud cover reduces light, making fish more active and comfortable feeding. Early morning and evening, when temperatures are cooler, are also prime times. A slight breeze can stir the water, stimulating feeding activity. Consistent weather often leads to better catches.

Are fish bothered by rain?

Fish aren’t typically bothered by rain; in fact, light rain can increase activity. Rain oxygenates the water and washes insects in, creating feeding opportunities. However, heavy rain may disturb fish due to strong currents, muddy water, or rapid temperature changes. Overall, rain’s impact depends on its intensity and duration.

Is rain good for ponds?

For ponds, rain helps to encourage plant development, oxygen, and water levels replenishment. It improves water quality by helping to dilute contaminants. On the other hand, too much rain can lead to runoff and bring pollutants, toxins, or too abundant nutrients damaging aquatic life. Maintaining a good pond ecology depends on balanced rainfall.

What does rain do in webfishing?

In webfishing, rain can impact fish behavior and accessibility. Light rain oxygenates water and stirs insects, attracting fish to the surface, enhancing the angler’s success. However, heavy rain may muddy waters, complicating visibility and casting. Strategic timing and adjusting techniques during rain can optimize results for webfishing enthusiasts.

What time do fish bite the most?

Fish bite most during dawn and dusk, known as feeding windows. These times offer low light, making fish feel safe and active. Cooler water temperatures in the morning and evening also boost activity. Tidal changes and moon phases can influence feeding times, so observing natural patterns improves fishing success.

What color do fish bite the most?

Fish often bite colors that match their environment or mimic prey. Bright colors like chartreuse and red work in murky waters, while natural tones like green and brown perform well in clear waters. UV-reflective lures enhance visibility. Experimenting with colors based on water clarity and light conditions improves fishing success.
