Bangkok has a hot-and-humid climate. There are 3 seasons in Bangkok; Summer (Mid of February to Mid of May), Rainy (Mid of May to Mid of October and Winter (Mid of October to Mid of February). Going outdoor in Bangkok during day time is sometimes unbearable as the temperature could go up to 38 Degree Celsius. The temperature is cooler in the evening and it is good walking around the city or chilling in some cool outdoor cafes.
* There is a joke that Thai people say it often which is “We are told that we have summer, rainy and winter; however, in fact, we only have hot, hotter and hottest”.
As can be seen from the charts above, the hottest month in Bangkok is in April and the coolest is in December. Plus, September is the month that is most likely to rain.
