It is possible to distinguish three seasons in Bangkok as follow:
- The hot-dry season
February to May with an average day temperature of 34˚c and 75% humidity
- The wet (monsoon) season
June to October with an average day time temperature of 29˚c and 87% humidity
- The cool season
November to January when temperatures range from 32˚c to below 20˚c with a drop in humidity.
The monsoon season in Thailand does not involve months of continual rain. There is a rainy, warm, and cloudy southwest monsoon from mid-May to September, as well as a dry, cool northeast monsoon from November to mid-March. The southern isthmus is always hot and humid.
