The temperature in Xishuangbanna all year round.

The annual average temperature in Xishuangbanna is about 18℃-22℃.

The coldest month in Xishuangbanna is 65438+ 10, and the average temperature is as high as 16℃, which is equivalent to the temperature in mid-spring and mid-autumn. The average temperature in July is only 25℃, which is not very hot. So there is actually a tropical climate with no winter in summer and no spring in autumn. Since there is no winter in Xishuangbanna, it is certainly not all year round.

The alternation of rainy season and dry season is very obvious there. First of all, there is a great contrast between the rainy season and the dry season. The total rainfall in the five months of rainy season (June-65438+1October) accounts for 86% of the annual rainfall, while the average rainfall in the driest February is only 1 1.4 mm. Secondly, the rainy season is fierce. Every year in late May, there will be several days of rainy season rainstorm, and it will quickly advance from south to north, so the international meteorological community generally calls it South Asia.

Because there is no winter in Xishuangbanna, crops can grow all year round, so the influence of climate on local agricultural production (mainly rice) is mainly rainy season and dry season, not temperature. For example, the rainy season ended too early in the late summer of 2009, and the water storage in paddy fields was insufficient in winter, which led to a rare drought in Yunnan in the spring of 20 10.

The hottest time of the year is not midsummer, but April-May before the rainy season. When the rainy season enters, the temperature drops. 9 1% appears in late March to late May, and the days with the highest temperature above 40℃ only appear in April and May. This is because clouds and rain block a lot of sunlight heat, and the sunlight heat reaching the ground is used for evaporation, so the temperature is naturally lower than that in April and May in dry season.
