Why do I feel that the temperature in the winter weather forecast is on the high side, not on a certain day, such as the coldest three or nine days, and the temperature is-16 to-1 degree and March?

The temperature measurement of the weather forecast is to put the thermometer in the louver box and not accept the sunlight. And people feel warmer when they are in the sun and are exposed to the sun, which is called sunshine. But sometimes, due to the cold current and strong wind, the strong wind takes away a lot of heat from the body, making people feel colder.

Sometimes the weather forecast is inaccurate, especially in summer.
