Weather in Thailand tends to be hot and humid year-round, with slight regional variation and seasonal change. The climate in Thailand is tropical, and expats will soon find themselves well acquainted with the monsoon, a seasonal wind that can bring heavy precipitation.
For the most part, the weather in Thailand can be broken up into three major seasons: the dry, cool season (November to February), the hot season (March to June) and the rainy season (June to October). The southern part of the country is less predictable and usually only experiences two seasons - the wet season and the dry season.
Temperatures in Thailand move up and down depending on locale; the north is the coolest area and the mercury rises as expats move further south. That said, even during the cool season the daily high can reach 68°F (20°C), and during the hot season averages settle around 93°F (34°C).
Expats should endear themselves to their umbrella during the rainy season. The entire country receives a fair bit of precipitation during the appointed period, and the southern region receives almost twice as much rainfall as the central and northern regions of Thailand.
At the height of monsoon season, tropical storms and typhoons are not uncommon. These extreme weather conditions have been known to cause floods and landslides. After the monsoon season ends each year, the country experiences a drought. Those living in rural areas are most affected but the effects trickle down to cities too.
