Although it is possible to catch silver carp and bighead carp at night in midsummer, the effect is far from that during the day. In addition to choosing sunny weather when fishing for silver carp and bighead carp, you must also pay attention to the wind direction and strength. Generally speaking, you should choose weather with a breeze below Level 3 or a southerly wind. Such weather generally has a higher temperature. If it is a windy weather above Level 3, Northerly weather is mostly cooler and cooling weather. This cooling weather is more suitable for fishing crucian carp, carp, grass carp, etc., but not suitable for fishing silver carp and bighead carp. If the wind is too strong, there will be layers of waves on the water surface in relatively open natural waters, which is not only difficult to observe the tiny movements of floats, but also makes it difficult for plankton and algae in the water to accumulate in the upper layer of the water, which is not conducive to the feeding of silver carp and bighead carp. Therefore, in such weather, silver carp and bighead carp disappear and are difficult to catch. Even if a nest is made during fishing, it is difficult for the nest bait to form a fixed nest area in the middle and upper layers of the water body.
