The influence of water temperature on fish and their bite

How does rain affect fish habitat?

Rain performs two functions at once:

1. Affects the temperature of the water in the reservoir; 2. Saturates water with oxygen.

Water temperature

Fish, like other living beings, loves stability. Since fish are cold-blooded creatures, the ambient temperature affects its body temperature and the metabolic rate in the body.

There is a water temperature at which fish feel comfortable. This comfortable temperature may be different for each breed of fish. For example, carp feels good at 20 degrees Celsius, ruff at 12 degrees, and burbot feels ideal at 5 degrees.

If rain changes the water temperature, bringing it closer to the “ideal” temperature, then fish activity increases sharply. If rain, on the contrary, moves this temperature away from some “ideal”, you can’t expect a bite.

Oxygen

An increase in the percentage of oxygen in water definitely enhances metabolic processes in the body of any fish. The fish begins to feed more actively.

How does the bite change during rain? It is impossible to answer this question unequivocally without reference to:

season;
weather conditions preceding the rain.

Best weather for perch fishing

The activity of perch becomes simply incredible in frosty weather with strong winds. This is for the winter season;
in particularly hot summer weather, the perch is not as active as always. He tries to wait for his prey somewhere in the shadows;
perch is a predatory species of fish that prefers to feast on when the weather is not so hot. When the sun is hot, he eats exclusively in the morning and evening. And in cloudy, quiet weather, it can be active throughout the day.

Fish biting in the rain

At different times of the year, fish react differently to precipitation in the form of rain. Therefore, the fisherman always has to make allowances for the season in which fishing takes place.

Early spring

At this time, most reservoirs are covered with ice. The first thawed patches appear on the rivers. At this time, fish are looking for warm water, which can be found at the mouths of small rivers and streams.

At this time, any rain brings warm water, which the fish is waiting for, so its bite will intensify, with rare exceptions. The bite of a predator that loves cold water (burbot, whitefish, salmon, trout) will weaken. The rest of the predator will approach the places where the juveniles gather and will feed just as actively. Fish biting in the rain this season of the year can hardly be called overactive.

Late spring

The time when reservoirs warm up, fish prepare for spawning. The food supply is still weak. Most fish begin to actively feed. At this time the weather is quite unstable. It may be hot, which will give way to night frosts. The wind can bring a warm, almost summer shower or a cold cloud of light drizzle turning into sleet.

Warm rain raises the water temperature. Fish activity increases. You can expect a good bite at shallow to medium depths.

Cold rain lowers that same temperature. Only the winter predator can activate the bite.

Summer

In principle, the post-spawning period on any body of water can already be considered summer. It occurs on each body of water at different times. Accompanied by an increase in water temperature, rapid growth of aquatic vegetation, and water blooms.

During this period, any rain saturates the water with oxygen, therefore it has a beneficial effect on the metabolic process in the body of most fish. Ingoda, even cold drizzling rain, especially coming after a long heat, activates the fish bite in the middle and upper layers of water.

Autumn

The fish is preparing for winter and gaining fat. The water temperature gradually decreases.

During this period, rain usually lowers the water temperature even further. The fish leaves shallow water areas following the remnants of warm water to the depths, into the pits. Cold rain only speeds up the process of this exodus of fish.

Features of fishing in the rain

For fishermen who use artificial baits (except fly fishing enthusiasts) and bottom gear for fishing, the rain will not bring much concern. Unless in heavy rain visibility is reduced, it is difficult to make accurate casts over long distances.

In heavy rain, float fishermen are better off postponing their fishing trip or waiting out the rain in some shelter.

In moderate rain, float fans may face two serious problems:

poor visibility, due to which it will be necessary to use more visible floats in the equipment;
sticking of the fishing line to the body of the rod, to overcome which you need to use a heavier float and preferably two types of rods - fly or match. In the first case, you have to make a short cast. In the second, sticking of the line is prevented by the design of the rod guide rings. Guide rings on long legs prevent wet line from even touching the rod body.

Fishermen face a particular problem when it rains in bodies of water with currents - the water becomes cloudy and the fish no longer see the bait.

In light rain you can fish with any type of float rod, although long casting will be a little difficult if you use light equipment.

It will add comfort to the fisherman if he is properly equipped for the season in the rain.

Fish biting after the rain

In spring and autumn after rain, the intensity of the bite changes little. We can talk about increased bite after rain only in the summer, when the rain has lowered the temperature of the water in the reservoir and saturated the surface layers with oxygen. The fish bite definitely increases after rain in summer. In other seasons, things are not so simple.

When the rain stops, fishing conditions on the reservoir change:

the water level rises, which means the working depth of fishing changes;
water transparency changes. The fish begins to see less clearly and becomes less cautious. Can be successfully fished at shorter distances;
During bad weather, stream streams erode the top layer of soil and wash away worms living on the banks into the water. The effectiveness of fly fishing and surface lure fishing increases dramatically. The floater can practice fishing in shallow waters and near the surface;
raindrops knock insects hiding there from leaves and branches. Not everyone is able to get out of the water on their own. The fish rises to the surface, attacking insects. Unfortunately, everything said above is completely true only in relation to summer fishing. In spring, the fish stay in shallow water and in the upper layers of water. And in the fall, the number of insects in the air decreases sharply, and the fish will move to greater depths as the water temperature drops. Its activity will decrease almost to zero;
Rain usually comes with changes in atmospheric pressure and wind direction (strength). Large fish do not like sudden changes in weather, so it is difficult to count on catching trophies. Although there are exceptions. Especially when the rain replaces the drying heat with damp coolness. Then, in a short period of time, large specimens of the same carp can become active.

Atmospheric precipitation and fish bite

Atmospheric precipitation falls from rain clouds formed as a result of a decrease in pressure (precipitation, warm front) or as a result of convection - convection clouds (rainfall, cold front).

In winter, precipitation is always associated with cyclones and low pressure that accumulates clouds; in summer, there is no strict dependence of precipitation on pressure.

Sign: if bubbles form on the water during rain, low pressure has established.

Fish biting before and after rain

How does rain affect fish bite? In addition to the fact that rain is a consequence of changes in pressure or redistribution of air masses, which in itself affects the fish bite, a significant amount of precipitation can cause a decrease in water temperature, an increase in water level, and the entry of various food into the reservoir along with rain streams.

Observations show that after a long period of heat, rain has a positive effect on fish biting. Often, fish bite better before rain, if it is caused by a decreased pressure level. A good fish bite after rain is associated with an improvement in the temperature of the reservoir and an increase in the amount of dissolved oxygen.

The fish bite in the rain may worsen if it is a long autumn rain with cold weather.

Best weather for fishing

In the song, every weather is a blessing and often has a changeable effect on the fish’s bite. What's the best weather for fishing?

According to the stories of many anglers, even bad weather brings surprises to the bite. So burbot loves cold, icy weather, when even a person has a hard time fishing.

In the summer heat, pike loves a change in temperature towards a decrease, cloudy but even weather. During breaks in bad weather, many peaceful fish begin to actively bite, providing anglers with unforgettable moments.

The influence of atmospheric pressure on fish biting

First of all, the behavior of fish is influenced by atmospheric pressure. The fact is that, due to the physiological characteristics of the structure of the air bladder, fish are divided into open vesical and closed vesical. In the first category of fish, the bladder is connected to the pharynx - these include bream, roach, crucian carp and others; in the second category (pike perch, perch and others) the swim bladder is completely isolated. When the pressure in the atmosphere changes, the pressure inside the bubble changes.

Open bladder fish have adapted to equalize pressure by swallowing air from the surface of the water or from plants. They begin to feel hungry as soon as the body adapts to new conditions.

Closed bladder fish react most painfully to pressure surges and, therefore, may not feed for a long time; when pressure increases, they rise to the upper layers, and when pressure decreases, they go to depth.

Thus, we can firmly state that the most favorable atmospheric pressure that has a positive effect on lion fish is pressure that has been stable for several days. Let it be 740 or 770 mm. rt. Art., but within the last 3 days. The ideal atmospheric pressure is considered to be 760 mm. rt. Art., again subject to its preservation for a certain time.

At what temperature is it better to fish?

The best bite is observed during moderately warm weather with pressure close to normal (i.e. 760 mm Hg). However, if low or high pressure remains stable for a long period, the bite may pick up slightly.

Changes in atmospheric pressure are closely related to changes in wind. So, with northern or eastern winds, the pressure begins to fall. That is why the fish bite sharply worsens during this period. The bite also worsens in stormy winds of any direction. The best bite is observed in light western, southwestern and southern winds.

After the rain the bite is more active. Is this true or not?!

After the rains, when the water begins to rise, the bite usually intensifies, then worsens and increases again as the water begins to recede. Cooling and clearing of water in summer sometimes have a positive effect on the bite. The best fish bite is observed in the early morning, good in the evening, and the weakest in the daytime, especially in the heat. On cloudy days there is a good bite even in the daytime. The bite improves as spring or late autumn approaches, when the fish bite throughout the day.

Does spawning time and fish behavior also affect the bite?

School reflexes during the spawning period have a particular influence on the behavior of fish; most of them lose caution and go into shallow water, where they become easy prey for poachers. Depending on the weather and water temperature, spawning time may shift in one direction or another.

What is the best way to fish depending on the weather?

The weather also affects the food supply of fish. Thus, with the onset of early spring, cyprinids quickly switch to plant foods. In addition, the number of insects that appear near the water, which the fish feed on, depends largely on whether the summer is dry or not. In dry weather, water bodies become shallow, the food supply becomes poorer - the fish move away from the shore and even make long migrations in search of food.

The best weather for catching crucian carp

Experienced fishermen advise catching crucian carp when the rose hips begin to bloom. After all, this period is the most productive in terms of fish biting. And crucian carp is a fastidious fish, and very dependent on the weather.

Naturally, such fish have their own requirements for the weather of the environment. And they are very serious. It is very important that the weather is stable . So, the atmospheric pressure should not change sharply. Ideally, it may have a slight deviation. Moreover, the weather must be sunny or cloudy for three days. But no more. Therefore, experienced fishermen always advise planning your crucian fishing in advance. To do this, you can simply view the weather forecast for this period.

If you are new to fishing, we recommend that you read the review of various gear for catching crucian carp.

It will be very difficult to attract fish to the desired fishing spot if at this moment the fish are not feeding as actively as usual. Only professionals can do this. So be careful. After all, it is best to hunt crucian carp in warm, stable weather with almost unchanged atmospheric pressure. Although light drizzle, fog in the morning, preferably thick, is also often accompanied by a good crucian bite.

Varieties of rain

Rain is atmospheric precipitation that falls from the sky in the form of drops ranging in size from 1 to 6 mm. There is very light precipitation. In such cases, they say that it is drizzling outside. The rain intensity varies. Droplets can land slowly, without causing much discomfort to a person. It’s easy to protect yourself from them, just wear a hat. It happens that a huge amount of rain falls in a short time. In just 10-20 minutes, streams and water streams appear on the ground. It's already a real downpour

As a rule, the more intense the rain, the faster it ends. Light rain may continue for a day or more. The downpour passes in half an hour or earlier. Rains can be mushroom, in sunny weather, torrential, prolonged (daily), oblique, streaky.

Which rains are conducive to fishing and which are not? We can definitely say that prolonged summer rains, accompanied by a cold wind from the north, are not favorable for fishing. Usually at this time the pressure drops, and the fish are not just standing in the holes or on the bottom. She is passive and almost does not react to baits and bait offered to her.

The most suitable type of rain is heavy short-term rain, after which sunny and windless weather sets in. In summer, the bite becomes more active, and the fish takes the bait very boldly. Drizzling rain with a warm slight wind is also good for fishing.

In general, when precipitation occurs, oxygen levels increase. It is for this reason that the fish bite improves.

Should you go fishing if rain is forecast?

Before going fishing, you should check the weather forecast. Is there any point in planning this event if it's going to rain? It all depends on the nature of the rain, the pressure and the air temperature. For a better understanding, here are two different examples.

In the first case, we have a forecast that short-term rain with thunderstorms is expected in the middle of the day, but without significant cooling and with further clearing. This happens in the middle of summer. In the morning it feels stuffy and partly cloudy. After lunch, as predicted, it rained quite heavily. After it, the temperature dropped a little, there was no more heat and it became very fresh outside.

Naturally, underwater inhabitants react to such changes. The fish are biting more actively. The hooks are good, and the fishing itself is interesting and productive.

The best weather for pike fishing

Experienced fishermen note that there are weather conditions that are most suitable for catching a toothy predator. Therefore, hunting for pike in pike weather will bring a larger catch.

As you can see in the video, pike are not afraid of clouds - the bite is often active:

Many people agree that the toothy fish bites more often in cloudy weather with little wind. Although, on the other hand, in clear and windless weather, when the surface of the reservoir is clean and smooth, the predator is good at baiting. It follows from this that the pike bite depends on the weather of the environment, but it is different for each season.

Read the review article, which breaks down the best pike lures for spinning fishing.

Whereas in the spring, with sunny weather and the first warmth, the pike begins its pre-spawning feast. She will swallow everything you offer her. The situation will change for the worse only when atmospheric pressure surges begin and the weather begins to change. This is what the toothy predator does not like at any time of the year - sudden changes in environmental pressure .

In winter, pike prefers a quiet and clear day, and in summer, on the contrary, it is cloudy. In autumn, the toothy one loves the wind and incessant rain for several days.

What should you take with you when fishing in rainy weather?

To feel comfortable on a rainy day, be sure to take a set of spare clothes, a raincoat and rubber boots. A good option is a suit consisting of a jacket and pants made of waterproof fabric. Dry spare clothes are needed if you are staying overnight.

A tent is a reliable protector from rain. Modern tents are made of waterproof fabrics and can be set up by one person. The best option is an automatic tent. It unfolds itself. You just need to do a few simple operations. You can easily install it in a minute.

If you are used to spending the night in a tent, be sure to take an air mattress or a small cot with you. A folding bed will be appropriate if you come fishing by car. The mattress takes up much less space. Very successful models that do not need to be inflated. This mattress unfolds, an air hole opens, and in 10 minutes it inflates itself. The height of the air layer is approximately 5 cm. This product is a successful substitute for a home bed.

There are also models with a pillow. This is perhaps the ideal option.

It is very important to take a sleeping bag with you. It will be comfortable even in wet weather. As for an umbrella, a beach umbrella with a large hat will do just fine. It fits in a case for medium-sized rods. There are umbrellas designed for fishing in rainy weather. They are a successful symbiosis of a tent and an umbrella.

As you can see, the angler is maximally protected from the rain and can wait for bites without feeling either the wind or drops falling from the sky. The only drawback is the sound from precipitation falling from above. But with a good bite, this nuance fades into the background.

For groceries, be sure to take a thermos with tea or coffee, or even better, a burner on which you can cook simple, tasty food and boil water for a hot drink. If you don’t want to cook, you can get by with sandwiches and soup in a thermos.

Another important attribute when fishing in bad weather is a fire source. It is better to have matches intended for camping conditions or several working lighters. You won't be able to light a fire. A gas burner with a cylinder is the best option for such conditions.

The influence of weather on fishing

When fishermen talk about good or bad weather, they usually mean their own feelings. For example, the summer heat is bad for fishermen, but for beach lovers it is great weather. Many anglers keep a diary of weather observations.

They record what air pressure is best for fishing in the summer, or how increased wind affects the bite from the ice. Each of the weather factors (pressure, precipitation, cloudiness, wind strength and direction) affects the fish bite individually and affects fishing in the aggregate.

In modern 21st century society, there are weather websites that you should check before going fishing. If a fisherman lives in a remote village without the Internet, he can find out the weather from the Hydrometeorological Center reports on a federal or local TV channel. Experienced fishermen determine the weather using folk signs.

But in the era of global warming, most signs no longer work and are considered outdated. Although our ancestors knew that if the weather was warm at Christmas, then spring crucian carp would be caught later than usual.

Or another sign: clear weather on Tatyana’s day, January 25, foreshadowed excellent fish bites in open water next spring and summer. There were a lot of such signs, and our ancestors checked the natural fish-biting calendar according to these signs, which were then rarely mistaken.

Modern long-term weather observations can also more or less accurately predict fish bite. Programmers cannot create an accurate fish-biting calendar, but they have computer programs that can show the relationship between weather and fish-biting with an accuracy of 70%.

Many fishermen use a special calendar and folk signs

Features of fishing during and after rain

It has been repeatedly noted that in rainy weather the fish prefers to go deeper. Therefore, catching it in shallow water is an unpromising activity. It is better to fish in wider water areas and throw the gear into the riverbed zone and near holes.

When fishing is done with donks and feeders, the bites are not as frequent, but more confident. Crucian carp, bream, roach and silver bream swallow the bait so that the hook has to be removed from the mouth with an extractor.

Often in the summer before precipitation falls, bites are rare. But as soon as it rains well, the fish begin to actively try the bait. Probably the falling drops activate the fish and make it wake up. And the increase in oxygen revitalizes underwater inhabitants.

An undoubted advantage of fishing in inclement weather is the small number of fishermen on the shore of the reservoir. You can choose a more promising area and don’t have to listen to the screams of deranged vacationers.

The effectiveness of fishing is greatly influenced by the presence or absence of wind. If the waves roll in one after another, then fishing with a float rod is not a very promising activity. But bottom gear will be more appropriate. It is enough to find edges and places with differences in depth and fish in such areas. Bites will follow with a certain frequency.

In general, peaceful fish often move closer to the shore in rainy weather. Therefore, it is better to focus on fishing on the first edge and in the coastal zone. The fishing distance in such cases, as a rule, does not exceed 20-30 meters. Sometimes it makes sense to fish at different distances. It happens that crucian carp and roach take better at close range, and bream and silver bream bite well near the riverbed or pit.

Fishing with a float is very promising near the coastal dump right behind the reeds, when there is light and monotonous rain and there is no gusty cold wind. In principle, there may be a slight southwest wind. In such cases, crucian carp, roach and bream willingly bite on worms, maggots, bloodworms and pearl barley. It often happens that large individuals sit on the hook. This is probably a kind of reward to the fisherman for his patience and diligence shown in such difficult conditions.

Separately, it is worth mentioning about fishing during a thunderstorm. In general, it is better to stop fishing in such cases and wait out the thunderstorm in a tent or car. Fishing rods conduct current and being on the shore at such moments is very dangerous. Manufacturers draw icons with a crossed out lightning bolt on the form. This is a warning to anglers that fishing during a thunderstorm is prohibited.

The photo clearly shows what the rod turns into when it is struck by lightning:

Fishing in the wire during the rain

Sometimes angling during rainy weather turns out to be very promising. In such conditions, the main thing is that there is a slight current in the fishing area, light rain and a slight breeze. The depth at the fishing spot is 1.5 - 2 meters.

It is better to fish with earthworms and underleaves, and with maggots. Fishing is carried out in the coastal zone with a fly rod with a float with a carrying capacity of up to 2 grams and a fishing line with a thickness of 0.14 mm and a hook No. 14 according to international numbering.

There may be some underwater vegetation on the bottom. We carry the bait along the bottom, but so that it is carried by the current closer to the shore. Often, a nimble roach actively attacks a worm or maggot and the float suddenly goes away or sinks. With a slight current and rain, the bottom layer is slightly agitated, and the larvae and worms are washed closer to the shore. Roaches and breams swim to such places to feast on meat food. That is why it is better to catch them with animal baits in such conditions. If there are caddis flies, even better. You can expect a very good bite from these larvae.

The active bite when fishing with a wire gradually subsides with the end of the rain. When the weather is calm, you can safely switch to fishing with donks and feeders.

Catching perch with a devil in the rain

We should also talk about such interesting fishing as catching perch with a devil in the coastal zone. Cloudy weather with light rain and cool temperatures are ideal for this type of fishing. This is usually caught in late summer and autumn, when there are more and more rainy days.

We will need a fly or Bolognese fishing rod 5-6 meters long and a blind or sliding float with a carrying capacity of 4-5 grams with a drop body and a regular antenna with a ball at the end.

A fishing line with a diameter of 0.6-0.18 mm will do. We surround the float so that it does not dangle in the current and the tip of the antenna is always in a vertical position. Devils of red and black colors are used as bait. Each hook has a red bead. If the pond has not very clear water, then you can also tie threads of red and yellow colors to the baits.

The weight of these baits is 3-4 grams. There is no need to place weights. We select the float so that it matches the weight of the devil. A worm, maggot or bloodworm is also attached to the hooks. You can attach different baits to each hook.

Fishing is carried out along the reeds and near the coastal dump. The devil is lowered to half-water and a little lower. Areas with current are selected. It turns out that the bait moves slightly above the bottom. Such fishing in the wire. While fishing, you can play along with the tip of the rod, making the devil dance. The depth at the fishing spot is 2-2.5 meters. The perch bites are reliable. The float confidently goes under the water or to the side. It is necessary to cut without tearing. A slight movement of the rod to the side and sharp hooks dig into the mouth of the striped predator.

Devil fishing is a popular fishing activity. You can fish in one place for 5 minutes or an hour. Depending on the size of the perch school. If we manage to catch a flock, then we catch it while there is a bite. As soon as the bites are over, we move on to the next section of the river. This fishing is very mobile and in some ways resembles chub fishing, when you have to change your location often.

Sometimes you have to put on wading boots and go closer to the reeds. At close distances, communication with such equipment is better controlled.

You don't need to feed the perch a lot. It is enough to roll a couple of small balls of earth with chopped worms and throw them into the wiring area.

Fishing in the rain: fishing location, wind, temperature

If you are fishing during the rain, then you should not be surprised if the water becomes cloudy. If the cloudiness of the water is slight, then the bite becomes better than in clear water, but if the cloudiness of the water is strong, then the fish bites worse. Much depends on which body of water you choose. Small ponds and muddy streams instantly become cloudy under the influence of rainwater, and it will become clear after only a few days. This means that if the weather forecast predicts rain, then it is more rational to go to a natural lake and deep reservoir.

The place intended for fishing should be located next to springs or streams flowing into the lake. In addition, the chosen fishing spot should not be windy. As already mentioned, the degree of turbidity of the water will also affect the success of fishing. If the water is cloudy and in the middle of the lake, then take a depth gauge and look for the coastal edge, in other words, the place where the depth changes. Throw your fishing rod there. The current brings worms to such places, which serve as bait for fish.

Wind and temperature also play a significant role when fishing in the rain. Experienced fishermen are convinced that a western or southern wind and warm rain are excellent conditions for a good bite and favorable fishing. In this weather the fish are much more active. It is excellent to catch perch, ide, and even predators, for example, pike. If the temperature has dropped noticeably or a strong wind is blowing from the north or east, then the fish prefer to hide in the depths. If it is cold rain, then it is best to postpone fishing for another time.

If you fish in water bodies overgrown with vegetation, then it is worth remembering that the fish in them respond excellently to bait. Then, half an hour after feeding the fish, you can start fishing. It is also worth considering that you will have to periodically change the bait, for example, dough to a worm and vice versa. If the fish begin to bite less or stop altogether, throw a little more bait than usual.

Precipitation

Precipitation has a big influence on fish bite. During prolonged heat, reservoirs dry out and fish look for new places. She moves to where it is deeper. If there is a heavy summer rain outside, it usually doesn’t bite at that time. And it is very uncomfortable for the fisherman to be on the pond at this time.

Therefore, you need to watch the weather forecast and take a raincoat with you. Precipitation that occurs over a long period at any time of the year has a bad effect on bites. If a little warm rain drizzles, then this has a good effect on summer fishing.

Fish often become active before stormy weather and after the storm has passed. If there is fog, then you should wait until it goes away, and only then the fish will start biting again. And if, in addition to the foggy dampness, a strong wind blows, then most likely there will be no bite that day.
