The temperature difference is very large. How to judge what weather is suitable for fishing?

Generally speaking, the temperature difference between 8 pm and 6 am the next day is called night temperature difference. It is difficult to fish when the temperature difference is more than 5 degrees at night. Many people are almost in the Air Force. You can go to the river to have a look. The turbid water suddenly became very clear. This is because the temperature difference is too big at night, and the fish stay in deep water. The next day, the fish felt cold and didn't want to move or eat. On the contrary, when the temperature difference is lower than 2 degrees at night, the catch will be better the next day. Because the temperature drops less, the fish will not feel cold and will still come out to feed as usual.

What kind of weather is suitable for fishing? There are many things to pay attention to, among which choosing the right weather conditions for fishing is an important aspect. And because weather factors have a great influence on fishing, it is even more critical to choose the right weather. There are many things to pay attention to when choosing the weather.

First of all, the overall weather situation is generally easier to control in sunny days than rainy days, especially in rainy days, and there are many uncertainties. It is recommended to fish in sunny days. In addition, there are some specific weather factors, such as temperature, air pressure, temperature difference between day and night and so on. The first is the temperature. When fishing, the temperature should not be too high or too low. Generally speaking, 15℃ to 25℃ is more suitable.

Then the air pressure. Too low air pressure will cause too little dissolved oxygen in the water, and too low air pressure will prevent fishing. Generally speaking, you should at least fish when the air pressure is 100kpa. Then there is the temperature difference between day and night, which is too big for fishing. Generally speaking, the temperature difference between day and night should not exceed 10 degrees. Therefore, when choosing the weather, we should fully consider various factors and comprehensively choose the most suitable weather, so that the fishing effect can be better.

Compared with the highest temperature every day, the temperature difference and the lowest temperature of the day are the key temperatures that affect the water temperature, and the water temperature affects the fish. Because the temperature can rise in a short time, and the water temperature is gradually rising, if the temperature and water temperature are too different, it will cause discomfort to the fish. Therefore, the close temperature difference and the stable and continuous minimum temperature are the key references to consider the change of water temperature, and they are also the key points that we need to pay special attention to. Take the lowest temperature on 25/26/27/28 as an example. As shown in Figure 2, the minimum temperature changes very smoothly these days, but the temperature difference of 25-26 is too large for fishing. On 27th and 28th, the temperature difference becomes smaller and the lowest temperature is stable, which is especially suitable for fishing.
