Cloudy weather, flickering, fish are extremely active and gluttonous, which is a good weather for fishing. If it was rainy and cloudy a few days before fishing, although the sun was shining that day, the heat increased by the light radiation received by the water surface turned to be lost because of the cloudy and sunny weather. Therefore, the water still maintains the characteristics of cloudy days, the water temperature is still cool and suitable for fish, and fishing can still be carried out on cloudy days. If it turns sunny and cloudy a few days ago, although the highest water temperature may be lower than in the past, the fish are more active and gluttonous than usual, and the activity time is extended, but the fishing time is longer than that in sunny days, and the fishing method is the same as that in sunny days.

Second, it is not suitable to fish in the hot rain.

The sultry weather will suddenly reduce the air pressure in rainy weather, resulting in severe hypoxia in the water. At this time, the fish are oppressed and irritable, struggling desperately for a mouthful of oxygen, and some even float to the surface to absorb oxygen, and have no intention of looking for food. The fishing proverb says, "It is better to catch after sunset than before the thunderstorm". Because before a thunderstorm, it is usually sultry weather. Therefore, it is not suitable for fishing in hot and rainy weather.

Third, the fishing rate is high after thunderstorms.

In summer and autumn, there was a thunderstorm the day before, and the fish were particularly easy to catch the next day, and the fishing rate was extremely high. Because after the thunderstorm, the climate is cool and pleasant, the water is full of oxygen, food increases, and fish are very active in activities and foraging. If the water rises, it will be especially effective to hook it in ponds, fish ponds and reservoirs. However, rivers, streams and rivers are flooded, so it is not suitable for fishing for a while. The reasons are as follows: First, the water flows rapidly after the water rises, which makes the fish panic and have no intention to feed; Second, the water quality is too turbid, and it is not easy for fish to find fishing food. However, when the water recedes, the effect of fishing by the backwater and water grass is very good. When the water flow is stable and the water color is slightly clear, the fishing rate is high.
