How to correctly judge the relationship between fishing and weather

First, look at the temperature difference at night.

Even if the amplitude is sometimes large and sometimes small during the day, the temperature is generally decreasing at night. Therefore, we call the temperature difference after dusk, around 8 pm and around 6 am the next day the night temperature difference. The temperature difference at night is closely related to fishing. When fishing in winter, the room temperature is generally around 10 degrees. When the temperature difference is more than 5℃ at night, it is difficult to fish, and it is likely that the Air Force will return when going out for wild fishing or fishing in black pits. At this time, when you go fishing in the black pit or river during the day or at night, you will often see that the muddy water on the shore has become clear and even crystal clear. This is because when fishing in winter, the temperature drops a lot at night, which is particularly cold. Fish hide in deep water and won't swim to the shore, so the water on the shore is particularly clear. When you fish all day, you often don't see the float. On the contrary, when the temperature difference at night is less than 2℃, the temperature drops very little at night, and the fish will not feel particularly cold. They still swim around at night and eat normally for the next two days. Fishing in this weather will pay off.

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

In addition to the temperature difference at night, special attention should be paid to the temperature difference between day and night when fishing in the wild or in black pits. Generally speaking, the highest temperature is about 2-3 pm, and the lowest temperature is about before dawn. 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 that the sun is too big during the day. When the sun shines high, the surface temperature of water will rise rapidly, which will lead to a larger temperature difference between the surface and the bottom of water and affect the foraging activities of fish. On the surface, the temperature rises in sunny days. 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.

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

In addition to the temperature difference between day and night, the minimum temperature difference between two days is also an important factor affecting the relationship between fishing and weather. If the lowest temperature today is lower than the previous day 1-2℃, the fish will be very inactive, which is bad weather for fishing. On the contrary, if the lowest temperature today is 1-2℃ higher than the previous day, the fish situation will be more active, which is a good weather for fishing.
