What are the temperatures in summer and winter?

The temperature and water temperature depend on the seasons, and it is generally 1.5-2.5 degrees in summer. High temperature: 3.5-4 degrees (the sun has great influence). 0-2.5 degrees in winter. The average difference is about 2 degrees.

Air temperature and water temperature are interrelated and influence each other. As the temperature rises, the water temperature rises; As the temperature drops, so does the water temperature. Generally speaking, knowing the temperature means knowing the water temperature. The two are interrelated and influence each other. As the temperature rises, so does the water temperature. As the temperature drops, so does the water temperature.

If the temperature is 10℃ at 6 o'clock in the morning, the surface water temperature is about 12 ~ 15℃.

At noon 12, the temperature is 20℃ and the surface water temperature is about15 ~18℃;

At 2 pm, the temperature is 24℃ and the surface water temperature is about18 ~ 22℃.

At 6 pm, when the temperature is 16℃, the surface water temperature is about18 ~ 20℃;

When the temperature drops to 8℃ at midnight, the surface water temperature is about 12 ~ 18℃.

In a word, the rise and fall of water temperature lags behind the change of temperature slightly.

Because water transfers cold and heat more slowly than air, there is a water temperature difference between the water meter and the bottom of the water. The deeper the water, the greater the temperature difference.

Influence of summer temperature/water temperature on fishing;

If you fish, it is best to fish in the waters with small temperature difference between the upper and lower parts in summer.

For example, if the surface water is 20℃ and the bottom water 10℃, the fish will float, so there will be no fish at the bottom, so we have to float or hang up for fishing.

For example, surface water 18℃, bottom water 35℃. When there is no oxygen in the bottom, the fish will float up and don't even eat. It is difficult to catch the floating fish because there is no fish in the bottom. Winter is the opposite of summer, so it's best to fish in waters with large water temperature differences.

For example, the upper water freezes, only 0℃, and the bottom water is only 2 ~ 4℃. Fish don't eat, but flee to deep water and warm water, so the bottom water can't catch fish.

For example, if the surface water freezes at 0℃ and the bottom water 10 ~ 15℃, then crucian carp, carp, bream, grass carp, herring and herring can all eat bait and be caught.

For example, when encountering a fish nest, the bait rate will not be worse than that in spring and autumn. This is also one of the important reasons why many northern fishermen like ice fishing and can achieve good fishing results.
