Bangkok weather by month

---

Source: Meteorological data for Bangkok is based on weather statistics gathered for the 30-year period 1991 to 2020 by the Thai Meteorological Department at the closest weather stations: Don Mueang International Airport (DMK) and Suvarnabhumi Airport (BKK), located respectively 23km (14mi) north and 30km (18 mi) east of Bankok.

Advice on the best time to visit a particular destination is based on average local weather statistics, when the weather conditions are generally better than at other times of the year. We consider high and low temperatures, risk of rain (and thunderstorms, etc.), amount of sunshine and sea temperature. For general outdoor activities we favour clear, rainless days with a temperature range between 18°C (64°F) and 27°C (80°F); and for hot-weather activities we favour clear, rainless days with a temperature range between 24°C (75°F) and 32°C (89°F). Often, the best times to visit correspond to high season and therefore involve higher prices.
