How to judge whether the weather is suitable for fishing that day?

1. The method to judge whether the weather is suitable for fishing on that day is as follows: The temperature difference between morning and evening is regular no matter which season. If this rule is broken, fish will not be so easy to catch. For example, the temperature difference between morning and evening in spring is relatively large, sometimes even between 10- 15 degrees Celsius. The temperature difference in summer is not small, about 12- 15 degrees Celsius. The temperature difference is the largest in autumn, and in some areas it is even between 13- 18 degrees Celsius. The temperature difference in winter is small, and 8- 15 degrees Celsius is the normal state. Throughout the year, the temperature difference between morning and evening is within this figure range, and the situation of fish is relatively normal, which has little effect on the mouth of fish the next day. Because fish is a cold-blooded animal, its body temperature changes with the water temperature, which can understand why fish keep silent when it is windy, hails and encounters cold current. Because of the rapid change of water temperature, they will feel uncomfortable, and some fish with weak resistance will die.

2. The minimum temperature changes two days before fishing. Fish living in water are very sensitive to temperature. Perhaps fish can adapt to low and high temperatures, but they are very resistant to rapidly changing temperatures. If the minimum temperature changes little two days before fishing, or it changes little (for example, within 5 degrees), it is normal, and the fish can adjust its body temperature in time without affecting the next fish mouth. However, if the minimum temperature difference exceeds 5 degrees two days before fishing (whether it is higher than 5 degrees or lower than 5 degrees), the fish will feel uncomfortable and will stop. Either hide in the deep water or float up. Fish is particularly difficult to catch anyway.

3. The temperature difference in the same time period and the temperature difference in the morning and evening. For example, the temperature at 9 o'clock last Sunday morning was 10 degrees, and the temperature at 9 o'clock this Sunday morning was 15 degrees. If you only look at this single data, it looks good and the temperature rise is safe. It should be windy weather. But if the lowest temperature last Sunday was only 2 degrees and the highest was 15 degrees, then the lowest temperature this Sunday was 5 degrees and the highest was 15 degrees. At first glance, it makes no difference, and the whole state is heating up. But if the temperature difference between morning and evening is not big, it is not normal for the temperature difference between time periods to change so much. If we compare the minimum temperature changes in the previous two days, it is easy to find that the temperature rise is too large and the fish mouth will not be very good.
