Rain collapses, the weather in May.

On the whole, May is the best. Because Yunnan is mainly divided into dry season and rainy season, June to 165438+ 10 is rainy season, and June to 65438+February is dry season. May is the end of the dry season and has not yet entered the rainy season, so it is the season with the highest average temperature in Yunnan. The mountains are full of azaleas, which is beautiful, suitable for hiking, and it is easier to see Meili Snow Mountain. After entering June, the rainfall increases, Meili Snow Mountain is often covered by clouds, which makes it inconvenient to walk in rainy season, and the temperature is low, which makes it easy to encounter mudslides. Please note, however, that the start time of dry season and rainy season is only approximate, not fixed, so you'd better look at the weather forecast in Yunnan before you leave, and don't go if there is much rain.
