How to judge whether you can go fishing in a day?

Many anglers hope that the weather forecast software is suitable for fishing to judge whether the weather is suitable for fishing that day. In fact, sometimes the prediction is inaccurate, or even the opposite.

In spring, the most important thing is the change of air pressure, while in winter, the most important thing is the change of temperature and temperature difference. Rain or shine, wind and rain will affect the temperature, and the temperature change will directly affect the fish through the change of water temperature. Fish is a temperature-changing animal, which has the habit of warming and avoiding cold, and has the instinct of regulating body temperature to keep it consistent with the environmental temperature. The process of regulating body temperature may be a painful physiological process, which will cause fish to be lazy. So there must be some connection between fishing and temperature difference.

There are many kinds of temperature differences, including day-night temperature difference, night temperature difference, time difference, water temperature difference, seasonal temperature difference, water temperature difference and so on. The temperature difference between day and night and night can also be included in the time interval temperature difference. This paper focuses on the important influence of the temperature difference for one or two days or a period of time on the fish situation in winter, especially around the coldest New Year's Day.

The change of temperature is not a straight-line rise or a straight-line drop, but a wave-like rise or a wave-like drop. In the wave-like temperature change, the breakthrough point of fish situation change may be found.

To judge whether the weather is suitable for fishing, we must do four things.

First, look at the temperature difference at night.

During the day, from dusk to dawn, the temperature drops gradually. The extent of the decline is large and small. We call the temperature difference at night after dusk, around 8 pm and around 6 am the next day. The temperature difference at night is closely related to fishing. When it is coldest in winter, the room temperature is around 10 degrees, and the temperature difference at night is more than 5, so it is difficult to fish, and it is likely to play whiteboard (in the air force).

When you go to ponds and rivers, you often see the muddy water on the shore become clear and even crystal clear. This is because the temperature drops a lot at night, which is particularly cold. Fish hide in deep water, so the water on the shore is particularly clear. Two days later, the fish still felt cold and was too lazy to talk. After fishing for a day, you often can't see the float. On the contrary, the temperature difference at night is less than 2, and the temperature drops very little at night, so the fish will not feel particularly cold, and they will still swim around at night and feed normally for the next two days. Fishing in this weather will pay off.

Second, look at the temperature difference between day and night.

The highest temperature in 24 hours is around 2-3 pm, and the lowest temperature is around 0 am. The greater the difference between the highest temperature and the lowest temperature within 24 hours, the more difficult it is to fish. The main reason for the large temperature difference is sunny and the sun is big. The bright red sun makes the surface water temperature rise rapidly, causing the temperature difference between the surface water and the bottom water to widen, which affects the foraging activities of fish. On the surface, the sun is shining and the temperature is rising. It seems that fish should be more active, but it is not, because of the "water layer temperature difference", the situation of fish is also very poor.

The daily maximum and minimum temperatures provided by the weather forecast can be referred to. If there is little difference between the two, it is more suitable for fishing. On the other hand, if the temperature difference between day and night is large, the harvest of fishing may not be great.

It is easy to fish on a cloudy day without cold wind in winter or on a cloudy day with flowers and sunshine (a little sunshine) because the temperature difference between day and night is small. On the contrary, the sun is shining, making people undress. The temperature difference between day and night is large, and the fish hardly take the bait.

The temperature difference at night is large, and the temperature difference between day and night is also large, so fishing is not allowed.

Third, look at the minimum temperature difference between two days.

The lowest temperature today is lower than yesterday 1-2, and the fish situation is very inactive, which is bad weather for fishing. On the contrary, today's lowest temperature is higher than yesterday's 1-2, and the fish is active, which is a good weather for fishing.

Fourth, look at the time difference.

In the coldest season, the days when fish take the bait are: the minimum temperature continues to rise (preferably greatly) and before the temperature drops, the air pressure is stable (preferably cloudy with light rain). In the process of rising temperature, it is still difficult to fish at first, or the effect of fishing is average.

Seeing the change of the lowest temperature is the key. How do you know the lowest temperature or something? The best way is to use the weather forecast of China Weather Network. China Weather Network has the weather on the hour, and we can see the data we need.

Knowing these data, we can choose the best fishing time. If the minimum temperature drops by 1-2, especially for several consecutive days, or the temperature drops by 4-5 at night, there is no need to travel; On the contrary, if the minimum temperature rises by 1-2 and the temperature difference at night is less than 2, it should be good weather for fishing. If the minimum temperature keeps rising, don't miss the opportunity.

There is a saying that you should "choose warm days and sunny days to go fishing." This statement is abstract and not necessarily appropriate. If the minimum temperature drops, the more sunny it is, the harder it is to fish.
