Source: Meteorological data for Pattaya is based on weather statistics gathered for the 36-year period 1980 to 2016 by the Thai Meteorological Department at the closest weather station: U-Tapao–Rayong–Pattaya International Airport (UTP), located about 30km (18mi) south of Pattaya. This station is deemed sufficiently nearby to be relied upon as the primary source for historical climate records, although weather conditions in Pattaya may vary slightly.

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.
