South Vietnam with its sub-equatorial climate, has two main seasons: The wet and the Dry season. The wet season lasts from May to November though June to August are the wettest month in Ho Chi Minh City.

The dry season lasts from December to April the next year. The annual average temperature is 28 C and there is almost no winter. So, the climate is particularly favorable for tourism all year round.
