What season is the continuous temperature 15 days 15 degrees Celsius?

Meteorological sense of spring, summer, autumn and winter: winter is the time when the average temperature is lower than 10℃ for five consecutive days. For five consecutive days, the average temperature is higher than 10℃, and below 22℃ is the spring and autumn season. Summer is when the average temperature is higher than 22℃ for five consecutive days.

Judging from the climate change in China, the temperature from 10 to 15 degrees is generally the temperature in spring and autumn. At this time, the temperature and climate are relatively cool, so keep warm. It is recommended that people who are weak and sick wear windbreakers, coats or sweaters. The weather is changeable in spring. As the saying goes, children change their faces three times a day in spring and need to increase or decrease their clothes appropriately.

There is also a saying that you should wear more clothes in spring and freeze in autumn, which I think makes sense.
