Thailand’s tropical climate is typically divided into three seasons: the hot season, the rainy season, and the cool season. The hot season, from March to June. The rainy or monsoon season extends from July to October, characterised by afternoon downpours, though the rain often provides a welcome respite from the heat. The cool season, from November to February, offers more comfortable temperatures, especially in the northern regions, making it a popular time for tourists. The chart below shows the weather for various locations across the country in 2022; of course, every year is different. But this gives some indication of recent trends. See our regional guides for up to date forecasts.
