Is it suitable for fishing when the temperature is 8 to 13 degrees in cloudy days after beginning of winter?

Small temperature difference, easy to fish. Fish is a temperature-changing animal, and its body temperature should be basically the same as the water temperature (the temperature difference between fish's body temperature and water temperature should not exceed 3 degrees) before it can take the initiative to feed. If the temperature difference is too large, the temperature difference of water temperature will be very large, so the fish will constantly adjust their body temperature to adapt to the change of water temperature, feel uncomfortable and will not take the initiative to eat. 8~ 13 degrees, the temperature difference is only 5 degrees, which has little effect on the water temperature. Fish can easily regulate their body temperature, which is very suitable for fishing. Moreover, there is no big sun on cloudy days in winter, and the temperature fluctuation is small, so you can fish all day.
