Yunnan has a large territory, and the climate varies from place to place. When Kunming wears short sleeves, Dali and Lijiang will be much colder, and they may all wear cotton-padded clothes, while Xishuangbanna is hot during the day, but the temperature difference between day and night is great, so it is relative when to go to Yunnan for the most beautiful scenery. Take Kunming as an example. In principle, there is no obvious difference between the four seasons in Kunming. The annual average temperature is around 20 degrees, with a minimum of not less than 15 degrees and a maximum of not more than 32 degrees. It is called the Spring City and is suitable for traveling all year round. If we have to analyze the advantages and disadvantages, then the precipitation is relatively concentrated from May to October, which will have a certain impact on outdoor activities. However, from March to the end of October, Kunming is also a season of flowers and fruits, and there are many ethnic festivals. At this time, Kunming has the most beautiful scenery. Relatively speaking, it is suitable to go to Diqing from May to October, to Northeast Yunnan from November to March of the following year, to Lijiang from March to November, to Dali from March to May from September to November, to Southwest Yunnan and Nujiang from October to May of the following year, to South Yunnan and Southeast Yunnan from November to April of the following year, and to Kunming and Central Yunnan all year round. Some people say that Yunnan is a place to visit at least four times, and there are different scenery in different seasons all year round, so whenever there is a holiday, you should set off for Yunnan, the most beautiful place at that time.
