Most countries have four seasons: Spring, summer, fall and winter. However, in some places, like Thailand, there are only three seasons: summer, the “rainy season” and winter. A " rainy season "is a time of very heavy rain. In Thailand, the rainy season begins around June and ends around October. In this period of time, it can suddenly rain very hard. Sometimes the rain will continue for many days without stopping. During the rainy season, you should always carry an umbrella in Thailand. You never know when it will “rain cats and dogs”!
