Thailand is located in the tropics, which is dominated by tropical monsoon climate and tropical rain forest climate. The climate of tropical monsoon climate zone can be divided into three seasons, namely hot season (from mid February to mid May), rainy season (from mid May to mid October) and cool season (from November to mid February of the following year). Thailand has little rain in the cool and hot seasons, so it is also called dry season or dry season. The southern peninsula of Thailand is a tropical rainforest climate zone, hot and rainy all year round. The average annual precipitation of the whole country is about 1550 mm, which is less than that of other Southeast Asian countries (the area where the monsoon blows over has more precipitation, the average annual precipitation is 3000 mm), and the annual average temperature is 24-30 ℃.

Due to the different topography, the precipitation and climate in Thailand are quite different. The climate in Central China is relatively hot all year round, and the cool season is long and short. The temperature in hot season is about 24.6 ~ 35.5 ℃ and that in cool season is about 21.1 ~ 31.7 ℃; The southern region has a marine climate with sea breeze blowing through the whole year, so the temperature in hot season is relatively low, and the temperature difference between hot season and cool season is not large. The rainy season rainfall in southern region is frequent. From July to February of the next year, the rainfall lasts for 8 months, with an average annual precipitation of 2220 mm. The eastern region is close to the sea, with a pleasant climate throughout the year. The temperature in hot season is 25 ~ 33 ℃ and that in cool season is 21 ~ 31 ℃, The rainfall is frequent, with an average annual precipitation of 1860 mm. In the northern region, most of the mountains are far away from the equator, so the average temperature in the northern region is lower than that in other parts of the country, with the temperature in the hot season being 21-35 ℃, the temperature in the cool season being 17-30 ℃, and the precipitation being 1240 mm. The northeast region is mainly the plateau, which is far away from the ocean, and the temperature difference between the hot season and the cool season is very large, and the weather in the hot season is hot (23-35 ℃), In the cool season, the weather is cool (19 ~ 26 ℃), and the average annual precipitation is 1370 mm.
