WeatherThe weather in Thailand is very different between the rainy and dry seasons. From May onwards, Thailand gradually enters the rainy season，especially September and October, it rains heavy everyday.
The clothing is mainly short-sleeved, but as mentioned above, there are heavey rains in the rainy season and the temperature will be cool. Even in Phuket, southern area of Thailand, a jacket will help you a lot in rainy season.
Thailand is a tropical region with many mosquitoes. Bangkok is a little bit better,but you have better to bring Anti-mosquito solution if you go to Phuket and Chiang Mai.
