Thailand has a tropical climate with high heat and humidity, dominated by monsoons. There is nothing that people living in temperate climates would recognize as definite "seasons," as average temperatures in Thailand range only from "warm" to "very hot" (30-36°C). There is measurable precipitation, on average, in every month, ranging from 1 cm in January to 30 cm in September. The hottest month, on average, is April, when even natives complain about the heat and humidity! The "coolest" months are November through January, with temperatures averaging in the low 30's and lower humidity. Temperatures in the northern and northeastern parts of Thailand can be cooler in the "winter" and hotter in the "summer" than the rest of the country, including Bangkok.
IPST's Davis VantagePro weather station is located on the top of a building at their headquarters in downtown Bangkok, so this is definitely a site where urban heat island effects should be observable in comparison to sites in rural Thailand.
