Weather and Fishing

weatherThe earth consists of two pressurized environments (Air & Water). Sensible weather, the day-to-day weather that we experience everyday is one of many factors that affects fishing as well as our daily lives. Weather changes are caused by atmospheric changes in pressure (barometric pressure) driven by the fast moving river of air called the jet stream located at about 30,000 feet in the atmosphere!

A basic rule is that rising air (falling pressure) produces clouds and even the possibility of rain and snow. Sinking air (rising pressure) means clouds and precipitation development is suppressed, and usually brings clear skies and fair weather. Weather conditions do impact the catch rate indirectly of the species you are pursuing, and will depend on various interdependent factors such as: availability of fish, water depth, temperature, clarity, wind, and barometric pressure (The measurement of weight of the atmosphere above us)

Water Systems are pressurized environments. Water is much heavier than air. A cubic foot of air weighs 1/12 pound (lb). A cubic foot of fresh water weighs 62.4 lbs and a cubic foot of sea water weighs 64 lbs. Water pressure, like air pressure, is a function of weight; the deeper one goes the greater the surrounding water pressure. Therefore, the direct effects of changing barometric pressure (air) is greater on fresh shallow water species than deeper lakes or oceans where the depth of the water inhabited by deep water species makes the air pressure variations insignificant.

Air pressure and other variables:

imagesCAQSKW9DThe air that surrounds the earth is constantly placing pressure on the earth’s surface. As the jet stream drives the large areas of high and low pressure on the surface of the earth, these large pressure systems then in turn, drive the large-scale wind flows at the surface levels. As air inherently wants to move from higher to lower pressure (the reason why air wants to escape a bike tire and not vice versa) it will converge in a counter clockwise manner around low pressure, and diverge in a clockwise manner around high pressure. This is because the Earth is rotating and the Coriolis force (the deflection to the right of one’s motion on large special scales) results in the observed surface winds. These resulting surface wind flows create weather fronts, which are distinct boundaries from say cold-dry Canadian air, and warm-moist Gulf of Mexico air. There are three basic types of fronts: Cold, Warm, and Stationary.

Typically, low pressure is the “parent” system for these frontal systems, with cold fronts often extending from the center of low pressure and orientated to the south and west of the low center. Warm fronts often extend from the low center and are positioned to the east and north of the low center. When a warm front passes, pressure still tends to fall as the warm front is often out ahead of the low, meanwhile, when a cold front passes, pressure tends to rise because the low center has already passed, and high pressure is building. Understanding a front’s make up and the weather they bring is key to predicting weather events.

Cold Fronts: (High Pressure)

cold_front

As a cold front passes the air pressure tends to rise (air sinks) as colder and drier air typically resides behind a cold front, which is more dense than warm-moist air, this can be recognized by clearing skies after inclement weather. Also, you may notice strong northerly winds after a cold front passes. This is because of the clockwise wind flow around higher pressure, coupled with a large change in pressure between the relatively close area of lower pressure, and the impending area of higher pressure. These abrupt weather changes disturb the environment, and most game fish will seek deeper water and or cover becoming inactive. The cold front effect on fishing lasts 1-2 days before another front moves in or the weather stabilizes.

If your fishing in a cold front here’s a few suggestions: If possible fish small darker water located on the small section known as Small Wawang, and if fishing the clear, deep part of Wawang Lake then it’s advisable to go deeper than 25′. Live bait is the preferred choice with a slow presentation; vertical jigging or slip bobbers are the best. Fish near the bottom or in weeds, around cribs and rock piles. As cold fronts bring lower air temperatures reducing the water temperature fish during midday when the water is the warmest.

Warm Fronts: (Low Pressure)

imagesCANYF207When a warm front approaches the air pressure is low, warm, moist air is rising and moving counterclockwise toward the center, creating less pressure. Because of this, a barometer usually shows falling pressure as a storm system approaches. Fish sense the drop in air pressure and become active, some fishery biologists attribute the increase of feeding behavior from atmospheric reduction in pressure that affects their air bladder another opinion is fish use vision as a primary feeding sense, as a storm hits with heavy winds this churns the water making it cloudy and more difficult to feed.

Here are some fishing tips during a low-pressure front: Cloud cover and rain is associated with low-pressure fronts, these reduce sunlight causing fish to move higher in the water column. Use surface and shallow running lures over weed beds, weed edges, and over open water if schools of baitfish are found. Faster retrieves are recommended, as fish are active. If storms become intense with thunder and lighting fish will become less active or “spooked” by these conditions and move to deeper water. From a safety point you should never fish during a lighting storm. Lighting may strike many miles from the center of the storm. Take shelter upon an approaching storm fishing rods make ideal lighting conductors.

Stationary Fronts:imagesCAQ8FKX7

A stationary front is a weather boundary between two different air masses (fronts) in which neither is strong enough to replace the other. They tend to remain essentially in the same area for extended periods of time. A wide variety of weather can be found in a stationary front ranging from sunny and fair to cloudy and even prolonged rain. Stationary fronts can focus lift in the atmosphere and can actually help develop areas of low pressure along them. This process results in the stationary front morphing into a warm front on the east side of the newly developed low and a cold front on the west side. This means that even stationary fronts can change with time and should be monitored for future implications on your luck out on the water.

Fishing during a stationary front rates good to excellent. Barometric pressure remains stable for an extended period of time. Fish develop a comfort level and a feeding pattern. Find the pattern of the specie your pursuing and your catching fish. Most fishing presentations work during this period. Best Fishing Times (Solunar – Moon Phase Tables) are based on using stable weather conditions.

imagesCA38RWSQWind & Clouds:

As the wind related proverb says “When the wind is east the fish bite the least, when the wind is west the fish bite the best.” Wind is an influential factor in fishing behavior as it stirs the food chain, provides oxygen and cover from the sun with wave action. Constant wind blowing from the same direction over days will migrate game fish on the windy shoreline to feed on baitfish. Water temperatures will increase also as the surface water is pushed by the wind. This is especially helpful in Spring and Fall seasons as the angler seeks the warmest water. Westerly and Southern winds are proven to produce the best fishing results as the proverb states. Clouds and cloudy conditions have similar effects as wind by reducing sunlight on and near the surface. Light sensitive fish will become more active, a combination of light wind (chop) and cloud cover condition is excellent for surface lures.

How to Fish During the Cold Fronts

 

26.5 (2)
We’ve all had to face it at one time or another – waking up on the day of your fishing trip to a chill in the air and bluebird skies to boot. What you are experiencing is the passing of a cold front, a weather occurrence that can shut down fish, and cause severe headaches for an angler. Fishing will be tough – there’s no two ways about it – but it is possible to put some fins in the boat if you are prepared to alter your delivery.

Try these techniques the next time you face a cold front and watch your catch rate increase dramatically.

What is a Cold Front?
A common definition of a cold front is as follows: “A narrow zone of transition between relatively cold, dense air that is advancing and relatively warm, less dense air that is retreating.”

cold_frontA cold front actually takes a day or so before the drop in temperature sets in and the skies become blue. This typically shows itself in the form of high winds, rainy weather or thunderstorms. It’s those kinds of days where all hell breaks loose, as the approaching front is causing a disturbance as the differing masses come together.

As the cold front approaches, fishing can be excellent. Fish become wired and active, feeding up a storm and hitting baits with ferocious strength. Even the fish know that once the front passes, they will take on a neutral or negative mood, and will develop a case of lockjaw for a couple of days. So, they feed heavily in preparation of this ‘dormant’ stage.

If you can get out on the water as a front approaches, I would certainly suggest it. Enjoy it while you can, because within a day or so, things will be much different.
Post cold front conditions vary greatly from the actual cold front. Clear blue skies, calm winds and colder temperatures are the norm, and not the exception. The change in pressure and temperature seems to shut down the fish, causing them to retreat to heavier cover, sulk on the bottom structure and become extremely inactive.

woods and weedsWhere To Find Fish
After a cold front has passed, fish stage in predictable areas of a lake. Don’t expect fish to be moving around much, nor, will there be much activity in the open water shallows.

For northern pike, thick vegetation or heavy cover are good places to start. Most fish under these circumstances will snuggle into the security of some sort of structure, content to sit still and wait out the prospect of changing weather.  The thicker the cover you can find, the better your chances of having fish present.

Depending on the type of lake, walleye will either seek out a thick weed bed and position themselves smack dab in the middle, or if rocks and boulders are concerned, they will sit right on bottom, remaining primarily motionless.

No matter what the species, seeking out the shelter and comfort of thick vegetation or other structure is a likely scenario. Remaining in a neutral or negative mood is a given

Downsize Your Lures
Although a northern pike may have no trouble hitting a ten-inch lure during a ‘normal’ day of fishing, he certainly won’t be as forthcoming after a front has moved through. Scale back on the size of the lures you are tossing, downgrading to finesse style baits for a better reaction. Since you are downsizing your lures, lowering the thickness of your line is also a good idea. Not only will get more of a lifelike action with your baits, but also less likelihood of scaring away line-shy fish.
Lightweight lures and line are most certainly in, and will often be the only thing that gets the attention of a heavyweight.

IMG_5625

S-l-o-w Things Down
When fish are inactive, the last thing they want to do is chase down a fast moving buzzbait, or a spinnerbait cranked at a lightning fast tempo. They just won’t exert the energy, nor do they have the initiative to do so.

Work your baits in a ‘slow motion’ mentality. Even if it seems excruciatingly painful to be fishing a worm or tube with nary a movement, continue to stick with it. If anything, slow it down even more. Dead sticking a bait is a great technique that can bring positive results.

Think Vertical Instead of Horizontal
A neutral fish has a small strike zone or feeding window. What this means is, unless a lure comes within six-inches or a foot to a fish’s snout, he will not be willing, or convinced to strike it. The closer you can get to the strike zone, the better your chances for success.

Vertical baits work well in this situation because they can spend more time in the strike zone, as opposed to a horizontal bait moving through relatively quickly.

Switch to Live Bait
When the fish are finicky, switching to God’s lures is the way to go – you guessed it, live bait. Minnows, worms or leeches will all work well, and will play on a fish’s natural prey attitudes and preference.
Slip floats, live bait rigs and tipped jigs all have a time and place, and post cold front conditions are definitely one of them.

Scent It Up
If live bait isn’t available to you, making your artificials smell and taste like the real thing is the next best thing to do. Go with tried and true scents, including crawdad, shad and worm. Any extra second you can get a fish to bite and hold on, is an extra second you can get those hooks into him.

Cold fronts don’t have to be the kiss of death in fishing. Although the fish may of changed locations, and be reluctant to hit baits, it doesn’t mean they are uncatchable. All it usually takes is a change of tactics to get into some fish again.

Walleye Lures and Baits

To get a fish to bite, you need to know how, where, whe­n, and what it eats.

1 Dave

 

Walleye are most active in morning and evening. They feed on small yellow perch, small northern pike, lake herring, other small bait fish and you can often find them around schools of these smaller fish. They eat a lot, they’re aggressive, and they’re not picky, which is good news for you. Because walleye eat by sucking in water around their prey, you’ll probably want to try smaller bait.

Look for walleye around submerged rocks, weedy flats, bars or other underwater barriers in the lakes.  Wawang Lake is known for all these types of great structure.

Many predators like such obstructio­ns, which help them ambush their food. Walleye locate their prey by sight, which means you’re not likely to find them in sunny waters; they retreat coyly to the shadows or the darker depths, often in groups. walleye’s strong vision also means you’ll have better luck with brightly colored lures, and you might even want to experiment with different colors.

­In the case of walleye, to seek out their location, you’ll also need to consider the time of year. Walleye like water between 55 and 68 degrees Fahrenheit, and they move to follow it. In spring and fall, you’ll find them in the shallows of lakes. In summer, they’ll be a bit deeper — though you’re not likely to find them in very deep waters (more than 50 feet).

Now that you know those basics, let’s find out how you can choose the right baits and lures.

Types of Walleye Fishing Lures

Nature-Jigs-1-WhiteLures are designed to mimic a fish’s natural prey, so think about­ walleye’s eating patterns and food. Lures that move quickly will attract these aggressive hunters. Additionally, lures should be similar in size to the smaller prey fish.

If you’re fishing with a jig head, choose the jig head based on water depth — the deeper the water, the heavier the head. For deeper walleye fishing, you’ll want a jig head of about ½ ounce. In shallower waters, you can go as light as a 1/8-ounce jig head. If conditions are rough or windy, a heavier jig can help.

26.5

Depending on the time of year, you may want something that sticks close to the bottom, like a small but heavy jig (with a lead head) or a crank bait.   If you go with a crank bait, again, choose one that mimics walleye’s natural prey — narrow, and between three and five inches long.

In various fishing conditions, you might want to try:

  • High-action lures:  designed to go deep (especially in warmer months)
  • Crank baits:  such as shad raps, jointed shad raps, or glass shad raps (with built-in rattles)
  • A balsa lure: such as a rapala
  • Live bait jigs: (for casting or trolling at the beginning of the fall season)
  • A #3 or #4 spinner
  • Trolling crank baits with more subtle action (better for the colder months

Finally, you can key your color choice to the sort of water you’ll be fishing. Use brighter colors for weedy or muddy waters.

Obviously, your bait depends on your choice of lure, as well as the fishing conditions. Read on.

Types of Walleye Fishing Baits

182Remember that walleye’s behavior and location chan­ges seasonally — so, the b­ait that worked so well at the beginning of September might not be the best one for May. Come prepared to try a few different kinds of baits, and remember that every angler works by trial and error.

When the weather is cold, you may find the best results with live bait. In cold water, walleye are sluggish. The movement of live bait will likely be most effective at stimulating them to bite. Walleye are more aggressive in warmer weather, and that can sometimes let you get away with plastic bait, especially plastic worms.   But many anglers swear by minnows year-round.

If you’re using a live bait jig, try minnows, worms, leeches or red tail chub. With a spinner, try a piece of worm.

One approach you may want to explore is coordinating your bait fish to whatever is schooling in the water. If you see a school of perch, for example, walleye are probably feeding close by, so use a perch colored lure tipped with live bait. Then let your jig drop a few feet at a time, the better to imitate the movement of the bait fish.   Obviously, this requires a bit more observation, flexibility and patience on your part. But isn’t that why you go fishing in the first place?

WEATHER TIP
Try to time your walleye fishing expedition so that it’s not coming right after a particularly cold snap. You can often have good luck during the turnover — the time when the weather is getting colder — because walleye follow their food into shallower waters, and often into less protected areas. But a particularly cold snap changes a lake’s temperature patterns so dramatically that it tends to put walleye into hiding until they’ve adjusted. Gradual changes are likely to offer better fishing

How To Cook Walleye
Now that you know how walleye eat, it’s time to learn how you can eat walleye. Walleye makes for a delicious meal, and depending on the preparation, it can be quite healthful as well. Try grilling walleye with fruit chutney, horseradish or pesto for a low-fat entrée. You can also bake, broil, fry, smoke or blacken walleye. Walleye is flavorful on its own, so you don’t need to do anything elaborate or complicated.

The Sudden Storm

 A true story…….

survival4
On July 4, Doug Fehler, 56, was fishing with his wife and grandkids when a huge thunderstorm swamped his boat. As told to Kristyn Brady.

The boys, Carter, 9, and Charlie, who’s just 5, were casting for perch, while Kristye and I put out jug lines for catfish on Oklahoma’s Broken Bow Lake. We had made the trip up from Texas for a Fourth of July getaway. We’d been fishing for maybe 30 minutes when the sky rumbled. I looked around and saw a huge thunderhead, followed by a lightning flash. It had been a scorcher of an afternoon with a few scattered clouds, and the marina parking lot was packed less than an hour earlier when we launched my 15-foot bass boat, a restored 1980 Caddo, toward a series of small islands. But with the lightning, I thought it best to get off the water.

As we motored toward the edge of the cove, the storm cloud had grown and the sky darkened. The wind picked up, but we’d had more shelter than I realized before our boat cleared the last island, where we were spit out into some of the roughest open water I’ve ever seen. The wind howled and waves slammed into the side of the boat, spilling inside. Without notice, a 7-foot swell crashed over our heads. I struggled to turn us into the oncoming wind and waves, soaked but holding on. Fortunately, we were already wearing our life vests.

Wave after wave crashed over the bow, but I didn’t even notice the water rushing past my feet because I was so focused on keeping the boat straight and running. I heard Kristye yell from the rear, where she was sitting with Charlie. I looked back to see him sitting on the floor with water up to his armpits. He didn’t seem to understand the danger, and just looked back at me expectantly. I could tell Carter was scared, but he was quiet and clung to the rail next to me.

I started to panic. It had been less than 10 minutes, but it felt like we’d been battling the waves much longer. The gas tanks were floating. The cooler had escaped over the side. The battery was under-water. That’s when the engine died.

Without the engine, we were being pushed toward a rocky bluff. If the boat had turned broadside to the waves, the next one would have capsized us. I was just about to jump in to try and pull us to shore when I heard a ski boat speeding toward us. They were able to drag our craft—the transom end completely underwater—and beach it nearby. I stayed with my boat, bailing out, while the driver of the ski boat took Kristye and the boys to the marina. As they left, Charlie was crying in Kristye’s arms, and I couldn’t help but worry that splitting up was the wrong decision. They got some bumps and bruises on the rough ride back, but we were reunited an hour later on the dock, where we all shed a few tears.

My boat’s tri-hull design was not built for those conditions, but I knew that. I would never purposely steer into waves that size. We were blindsided. Carter still doesn’t like to talk about that afternoon, and he hasn’t been on a boat since. I’m hoping that will pass. The whole thing has kept me awake a few nights. I go over the experience in my head, thinking what was at stake. It still gives me chill-bumps.

Survival Analysis

survival5

Because one cannot fault Fehler’s actions once his boat was caught in heavy water—he made sure everyone was wearing a PFD, kept the bow pointed into the waves, and navigated toward safe harbor—the only question of right and wrong here concerns the decision to cross open water. The family probably could have weathered the storm in relative safety among the islands, and Fehler’s decision to leave is one I am sure he would like to have back.

This situation reminds me of an antelope hunting trip I made with my brother on Montana’s Fort Peck Reservoir, where we found ourselves separated from the dock by a mile-wide channel. Like Fehler, we didn’t have a boat seaworthy enough to meet the conditions once the storm broke. Unlike him, we were able to see how far conditions had deteriorated, so the decision to shelter on a spit of land was a no-brainer. We ended up being trapped by weather there for three days.

The survival lesson here is not so much to be prepared to brave the devil water, but to be prepared to stay, which makes a safe decision much easier. Always check the weather forecast ahead of time, and carry a radio, cellphone, distress flags, and signal flares, as well as a survival bag. Do not forget extra dry clothing, and make sure the book in your dry bag is a long one.

Weather and Fishing

weatherThe earth consists of two pressurized environments (Air & Water). Sensible weather, the day-to-day weather that we experience everyday is one of many factors that affects fishing as well as our daily lives. Weather changes are caused by atmospheric changes in pressure (barometric pressure) driven by the fast moving river of air called the jet stream located at about 30,000 feet in the atmosphere!

A basic rule is that rising air (falling pressure) produces clouds and even the possibility of rain and snow. Sinking air (rising pressure) means clouds and precipitation development is suppressed, and usually brings clear skies and fair weather. Weather conditions do impact the catch rate indirectly of the species you are pursuing, and will depend on various interdependent factors such as: availability of fish, water depth, temperature, clarity, wind, and barometric pressure (The measurement of weight of the atmosphere above us)

Water Systems are pressurized environments. Water is much heavier than air. A cubic foot of air weighs 1/12 pound (lb). A cubic foot of fresh water weighs 62.4 lbs and a cubic foot of sea water weighs 64 lbs. Water pressure, like air pressure, is a function of weight; the deeper one goes the greater the surrounding water pressure. Therefore, the direct effects of changing barometric pressure (air) is greater on fresh shallow water species than deeper lakes or oceans where the depth of the water inhabited by deep water species makes the air pressure variations insignificant.

Air pressure and other variables:

imagesCAQSKW9DThe air that surrounds the earth is constantly placing pressure on the earth’s surface. As the jet stream drives the large areas of high and low pressure on the surface of the earth, these large pressure systems then in turn, drive the large-scale wind flows at the surface levels. As air inherently wants to move from higher to lower pressure (the reason why air wants to escape a bike tire and not vice versa) it will converge in a counter clockwise manner around low pressure, and diverge in a clockwise manner around high pressure. This is because the Earth is rotating and the Coriolis force (the deflection to the right of one’s motion on large special scales) results in the observed surface winds. These resulting surface wind flows create weather fronts, which are distinct boundaries from say cold-dry Canadian air, and warm-moist Gulf of Mexico air. There are three basic types of fronts: Cold, Warm, and Stationary.

Typically, low pressure is the “parent” system for these frontal systems, with cold fronts often extending from the center of low pressure and orientated to the south and west of the low center. Warm fronts often extend from the low center and are positioned to the east and north of the low center. When a warm front passes, pressure still tends to fall as the warm front is often out ahead of the low, meanwhile, when a cold front passes, pressure tends to rise because the low center has already passed, and high pressure is building. Understanding a front’s make up and the weather they bring is key to predicting weather events.

Cold Fronts: (High Pressure)

cold_front

As a cold front passes the air pressure tends to rise (air sinks) as colder and drier air typically resides behind a cold front, which is more dense than warm-moist air, this can be recognized by clearing skies after inclement weather. Also, you may notice strong northerly winds after a cold front passes. This is because of the clockwise wind flow around higher pressure, coupled with a large change in pressure between the relatively close area of lower pressure, and the impending area of higher pressure. These abrupt weather changes disturb the environment, and most game fish will seek deeper water and or cover becoming inactive. The cold front effect on fishing lasts 1-2 days before another front moves in or the weather stabilizes.

If your fishing in a cold front here’s a few suggestions: If possible fish small darker water located on the small section known as Small Wawang, and if fishing the clear, deep part of Wawang Lake then it’s advisable to go deeper than 25′. Live bait is the preferred choice with a slow presentation; vertical jigging or slip bobbers are the best. Fish near the bottom or in weeds, around cribs and rock piles. As cold fronts bring lower air temperatures reducing the water temperature fish during midday when the water is the warmest.

Warm Fronts: (Low Pressure)

imagesCANYF207When a warm front approaches the air pressure is low, warm, moist air is rising and moving counterclockwise toward the center, creating less pressure. Because of this, a barometer usually shows falling pressure as a storm system approaches. Fish sense the drop in air pressure and become active, some fishery biologists attribute the increase of feeding behavior from atmospheric reduction in pressure that affects their air bladder another opinion is fish use vision as a primary feeding sense, as a storm hits with heavy winds this churns the water making it cloudy and more difficult to feed.

Here are some fishing tips during a low-pressure front: Cloud cover and rain is associated with low-pressure fronts, these reduce sunlight causing fish to move higher in the water column. Use surface and shallow running lures over weed beds, weed edges, and over open water if schools of baitfish are found. Faster retrieves are recommended, as fish are active. If storms become intense with thunder and lighting fish will become less active or “spooked” by these conditions and move to deeper water. From a safety point you should never fish during a lighting storm. Lighting may strike many miles from the center of the storm. Take shelter upon an approaching storm fishing rods make ideal lighting conductors.

Stationary Fronts:imagesCAQ8FKX7

A stationary front is a weather boundary between two different air masses (fronts) in which neither is strong enough to replace the other. They tend to remain essentially in the same area for extended periods of time. A wide variety of weather can be found in a stationary front ranging from sunny and fair to cloudy and even prolonged rain. Stationary fronts can focus lift in the atmosphere and can actually help develop areas of low pressure along them. This process results in the stationary front morphing into a warm front on the east side of the newly developed low and a cold front on the west side. This means that even stationary fronts can change with time and should be monitored for future implications on your luck out on the water.

Fishing during a stationary front rates good to excellent. Barometric pressure remains stable for an extended period of time. Fish develop a comfort level and a feeding pattern. Find the pattern of the specie your pursuing and your catching fish. Most fishing presentations work during this period. Best Fishing Times (Solunar – Moon Phase Tables) are based on using stable weather conditions.

As the wind related proverb says “When the wind is east the fish bite the least, when the wind is west the fish bite the best.” Wind is an influential factor in fishing behavior as it stirs the food chain, provides oxygen and cover from the sun with wave action. Constant wind blowing from the same direction over days will migrate game fish on the windy shoreline to feed on baitfish. Water temperatures will increase also as the surface water is pushed by the wind. This is especially helpful in Spring and Fall seasons as the angler seeks the warmest water. Westerly and Southern winds are proven to produce the best fishing results as the proverb states. Clouds and cloudy conditions have similar effects as wind by reducing sunlight on and near the surface. Light sensitive fish will become more active, a combination of light wind (chop) and cloud cover condition is excellent for surface lures.

Barometric Pressure

unnamed

Understanding barometer reading to fish by

The effect of barometric pressure on fishing feeding activity is one of the more interesting theories. In short,  the theory proposes that a dropping air pressure brings on feeding activity, rising pressure turns the fish off feeding, high pressure results in the fish moving to shallower water, and low pressure results in fish moving to deeper water. This article will provide an overview on barometric pressure, summarize various theories about why atmospheric pressure affects fishing activity, and then summarize in tabular fashion the generally accepted fish behaviours with various barometric patterns.

Barometric pressure is the measure of the weight of the atmosphere above us. A barometer is used to measure air pressure.  The earliest barometer consisted of a glass vacuum tube inserted into a container of mercury which was exposed to the pressure of the air.  Increased air pressure would force the mercury up the tube in a height proportunal to the pressure. The height was measured in inches (inHg) or in millibars (1 inch = 33.864 millibars). Although new types of barometers are now used, these measures are still in place. In general, 30 inHg or 1016 millibars is considered to be normal air pressure. In normal weather, 30.5 is considered extreme high, and 28.5 is considered extreme low. The measures are taken at sea level, a higher

elevation has less atmosphere above it, so a correction factor against the normal measure is needed depending on altitude.

 

It is believed that the effect of barometric pressure is greater in shallow water than deep, probably due to the pressure of the weight of the water in deep water being so high, that the air pressure above it is not relatively significant.

The principal theory, is that the effect of changing pressure on the swim bladders of fish makes them uncomfortable or dis-oriented. In this theory, the fish will move to feel well, or they feel bloated or full. With a lowering barometer, it is believed these fish move into deep water seeking higher water imagesCA1344Y9pressure and ride out the low pressure around structures.  The theory suggests that just prior to change from a high to a low, fish will bite like crazy until the low hits and then stop. The difficulty with this theory, is that water is 900 times more dense than air, and generates signicantly more pressure than air. In fact,a 3 foot wave will produce a variation of pressure more significant than can be expected from a change in atmospheric pressure through a dramatic change, and the wave effect is happening every few seconds, rather than the hours or days that the atmospheric changes takes to occur.

Frankly, given that the pressure of water depth is such a significantly greater factor than the pressure of atmosphere, it seems likely that the weather conditions created by changes in barometric pressure, such as clouds, rain and wind, have more effect on fishing than the barometric pressure alone. So in the opinion of the author, barometric change is a good indicator of fishing change, but it’s not because of the pressure change by itself, as much as what other weather conditions are likely to occur because of the pressure change.
The following table attempts to summarize the barometric pressure, and observations on fish activity and fishing techniques.

Pressure Trend Typical Weather Fish Behaviour Suggested Fishing Tactics
High Clear skies Fish seek cover, look for logs, weeds in shallows. If water too warm, will stop biting. Fish structure close to surface, with shallow crankbaits, poppers, etc..
Rising Clearing or improving Fish start to move out of deeper water.  After a day or so, go to normal feeding. Fish with brighter lures and near cover, moving from deeper water to shallower water.
Normal and stable Fair Normal activity. Experiment with your favorite baits and lures.
Falling            Degrading Most active feeding. Range of different methods. Surface and shallow running lures may work well.
Slightly lower Usually cloudy Fish seek deeper water, with water temp maybe also slowing them down. May need to settle before feeding again. Use deep running lures at a moderate speed.
Low Rainy and stormy Fish move to deeper structures, may not feed. Fish deep structures, vary your methods.

Of course, the longer a period of high feeding activity, the more likely the fish are to stop feeding and the longer the period of inactivity, the more likely the fish are to start feeding.

Draw your own conclusions on the effect of a changing barometric pressure on fishing activity. Whether pressure changes by themselves cause feeding changes may be in question, but the patterns seem to be there regardless.

‘There is certainly something in angling that tends to produce a serenity of the mind’
