Details about the weather in August

Bangkok and Central Thailand

Bangkok and Ayutthaya, as well as other destinations in the central region of the country, are not experiencing any major change. The number of days with rain increases slightly with an increased humidity value. Rainfall in Bangkok is less than in the destinations on the Andaman Sea. The maximum air temperature at noon in Bangkok usually doesn’t exceed 30°C. The difference between day and night air temperature is no more than 5-6°C with the consequence that the already very humid air becomes heavier. Local floods can occur in Bangkok as city's drainage system is overloaded and does not manage to drain torrential rain from the streets.

Eastern Thailand

The weather in Koh Chang and in the province of Trat in August is probably the worst of the whole year and the whole territory. It rains almost daily and the number of rainy days increases to 28 days on a long-term average. In August it often rains all night, during the day there is less rain. Daytime temperatures are around 30°C. At night they drop to about 25°C. The number of tourists at this time is at its absolute minimum. For a really drier August and wonderful sun exposure, travel to Pattaya.
