When is it generally not cold in winter in Shandong? How long can a down jacket last? I'm not particularly afraid of cold. I don't go out all day.

That depends on where in Shandong. For example, in coastal cities such as Qingdao, due to the influence of monsoon climate, the temperature in winter will be higher than that in inland cities such as Jinan and Zibo. But as a northern city, Shandong must wear cotton-padded clothes in winter. I wear it online now. Hehe ~ as for down jackets, according to the annual solar terms, you should wear them for two months after the new year ~

Only then did the temperature rise.

Shandong's climate belongs to warm temperate monsoon climate type. Precipitation is concentrated, rain and heat are in the same season, spring and autumn are short, winter and summer are long. The annual average temperature is 1 1℃- 14℃, and the regional difference of temperature in Shandong province is greater than that in the north and south. The frost-free period of the whole year increases from the northeast coast to the southwest, with 180 days in northern Shandong and Jiaodong and 220 days in southwestern Shandong.

Shandong province is rich in light resources, with an average annual light hours of 2,290-2,890 hours, and the heat condition can meet the needs of double cropping of crops a year. The average annual precipitation is generally between 550-950 mm, decreasing from southeast to northwest. The seasonal distribution of precipitation is very uneven. 60%-70% of the annual precipitation is concentrated in summer, and it is prone to waterlogging and drought in winter, spring and late autumn, which has the greatest impact on agricultural production.
