Some coastal cities such as Hai Phong and Quang Ninh may also experience flash floods and strong winds.

In Central Vietnam

It takes central citizens a long time (about 3-4 weeks) to recover their territory after the effects of floods that impacts significantly on the regional tourism. Nevertheless, Central Vietnam is still a worthy place to visit for its peace and people’s hospitality.

In Southern Vietnam

  • Average temperature: 28 Celsius Degree

In contrast, the Southern region, which includes Ho Chi Minh City, sees a harsher differentiation between dry and wet seasons. The wet season in the southern areas is characterized by short, intense bursts of rainfall, often followed by scorching sun.

Rainy season in the southern part often lasts longer than the two remaining regions, however, it does not affect the life pace of these cities because tourists coming to this region are likely to enjoy the wet season more than the hot one.
