It is no secret that many natural phenomena greatly affect the activity of the inhabitants of the underwater environment. Thus, sudden rain, gusty winds, changes in temperature and, of course, atmospheric pressure can improve or worsen the bite. About what atmospheric pressure for fishing is optimal and how to follow it further and will be discussed.
Atmospheric pressure and its impact on the living environment
Pressure is one of the most important characteristics of the state of the atmosphere. Normal pressure is 760 mm. rt. Art. It shows the weight of the air above. Any changes in these parameters affect the organisms living on Earth, both those on land and those that are under water.
Often, pressure becomes a harbinger of a change in weather. The inhabitants of rivers and lakes are exposed to it, therefore they react unpredictably to fluctuations in readings.
With sharp jumps, the density of water changes, as well as the level of oxygen dissolved in it. This occurs both with a decrease and with an increase in blood pressure.
What happens to fish when pressure changes:
- metabolism slows down;
- deteriorating oxygen saturation;
- underwater inhabitants become inert;
- refuse food.
Both a slow metabolism and oxygen starvation negatively affect the bite. Many fishermen who own aquariums can observe the impact of a natural phenomenon on the inhabitants of a home pond.

In shallow waters, with an increase or decrease in the barometer, you can meet roach, rudd or bleak, hanging with their tails up. In this position, the fish spends an unfavorable period, refusing any treats. Many representatives of the carp family lie on the bottom, and predators do the same: catfish, pike, pike perch.
A barometer is a device that shows the state of atmospheric pressure. It was invented back in 1966 by the physicist Evangelista Torricelli. As the first device, he used a plate with mercury poured into it and a test tube turned upside down.
As for the smooth decrease in pressure, things are different here. When the environment changes gradually, the fish remain active. It is not uncommon to find an excellent bite at low pressure, but subject to the condition that it does not fall sharply. Low pressure in the atmosphere is often accompanied by clouds and rain, which, in turn, mixes the water layer, saturating it with oxygen. The influence of the change of weather in summer is especially noticeable, when the heat subsides, the water becomes cooler and the carp begins to peck.
Influence of pressure in the atmosphere seasonally
At different times of the year, atmospheric pressure affects fish in different ways.
It depends on many factors:
- air and water temperatures;
- illumination and day length;
- oxygen saturation;
- biological rhythms of underwater organisms.
All these factors together determine the effect of blood pressure. In winter, for example, a sharp change in barometer readings will worsen the bite, because under a thick layer of ice and snow, every frosty day, less and less oxygen remains under water. In summer, in the heat, when the water area is saturated with oxygen due to higher plants and algae, fluctuations can stir up the inhabitants of the ichthyofauna.
Barometers are mercury and mechanical. At the moment, the second option is more popular. These products are both safer and more practical, they are not inferior in accuracy to the readings.
Spring pressure change
After a long ice captivity, the water areas gradually begin to come to life. Sharp temperature jumps, strong winds and pressure rises plunge the inhabitants of rivers and lakes into a stupor. On a clear windless day with a gradual rise in atmospheric pressure, the bite will be present.
If high pressure persists for three or more days, then the situation in the reservoirs is getting better. The same can be said about low barometer readings.
Spring is characterized by constant climatic shifts: heat is replaced by clouds with rain, a strong wind can precede a quiet evening. All this negatively affects the activity of the fish.
Pressure change in summer
Dry days with moderate winds and steady pressure around 160 mHg. Art. have a positive effect on catches. At this time of the year, sharp drops are also considered negative, but not to the downside. Low pressure with a cyclone often causes water dwellers to peck, however this only affects certain species.
Often in the rain, carp and crucian peck, and sometimes good results are obtained by fishing for pike with live bait tackle. A random rainfall on a windless sunny day can awaken fish that have not pleased with their activity for a long time. Which barometer is better for fishing is unknown. Each angler selects a device to his taste.
Pressure change in autumn
The rainy season is accompanied by low barometer readings, which occasionally rise to a normal level. During this interval, the fish goes lower, where the influence of atmospheric phenomena is not so strong. A good biting will be accompanied by sunny weather with normal or slightly elevated atmospheric pressure. Its optimal values during this period are in the range of 160-165 mm. Rt. Art.
Closer to freezing, the fish becomes passive. November is considered by many anglers to be a transitional period in which there is nothing to do on rivers and lakes. During this month, getting a bite becomes much more difficult, even with the most delicate rigging.
Pressure change in winter
During the ice fishing season, the best pressure is normal or slightly reduced. In cloudy weather with snow precipitation, roach is perfectly caught, in clear weather, perch pecks. Based on the readings of the barometer, you can build a fishing tactic: at high rates, you need to go in search of a predator, at low rates, look for white fish.
As in the other period of the year, drops and jumps are considered the most negative impact. Smooth lowering or lifting does not affect the bite.
