The Thailand climate is controlled by tropical monsoons and the weather in Thailand is generally hot and humid across most of the country throughout most of the year. While Thailand’s seasons are generally divided into the hot season, cool season, and rainy season, in reality it’s relatively hot most of the year.
The southern, coastal region of Thailand really has only two seasons – rainy season and dry season.
Cool Season (November - February)
Hot Season (March - June)
Rainy Season (July - October)
