Is the sudden drop of temperature in spring suitable for fishing?

When the temperature drops suddenly, the first feeling is that it is not good to fish. Because it is cold, I will take it for granted that the water temperature is also cold.

This is because temperature is largely confused with water temperature. Temperature will affect the water temperature, but it will take time. Especially in rivers and lakes with very large water area, whether it is heating up or cooling down, the influence of temperature on water temperature needs a process. It is impossible for the water temperature to drop immediately when the temperature drops at first.

Then for the sudden cooling, it is unlikely to affect the waters with large water surface in a short time. After all, in such a short time, the overall water temperature will not drop like a cliff. So fishing depends on the water temperature, not just the temperature.

Water temperature is the thermal effect of solar radiation, long-wave effective radiation, heat exchange between water surface and atmosphere, water surface evaporation, hydraulic factors of water body, geological and geomorphological characteristics of water body, recharge water source and other factors. So many objective conditions affect the water temperature, not just the temperature, so don't worry too much about the temperature.

After the sudden drop in temperature, I think it will be good for fishing. Fish have a strong sense of water temperature. When the temperature of the surface water layer drops, the fish will go to the bottom after sensing the temperature change, and most of our fishing is bottom fishing, which means that in a short time when the temperature suddenly drops, for example, the day before or even the day before, it is a good opportunity to fish.
