Vietnam Weather in September

If you are planning a holiday in September, you can expect to find average temperatures in Vietnam of 31℃, which can potentially rise to 35℃ in Hanoi. This can feel sticky and humid, especially if you are in central or southern regions that experience a higher level of rain as this month marks the start of the monsoon season.

The beginning of the wet season also means that the country-wide average rainfall reaches up to 160mm, but this depends on where you are visiting. As a rule of thumb, the north is much drier than the south. Admittedly, September is not the best time for a dry, sunshine-filled beach holiday, as rains shift into the central region, creating less than ideal sunbathing conditions.

Although it is the start of a low season in Vietnam in September, there are plenty of things to do in Vietnam during this time of year.

  • Better rates: Since September is part of a low season in the country, you can expect to find some deals, especially if your travel dates fall later in the month. This is because tourists are less likely to visit the country as rainfall increases.
  • Lesser crowds: Due to the less than ideal weather, especially around the popular beaches in Central Vietnam, there are fewer crowds in the south and central regions of Vietnam. If you have a decent waterproof coat, you might have beautiful sites and temples all to yourself.
  • Vietnam National Day: Celebrated on September 2, this is a huge event in the Vietnamese calendar, marking the day when Vietnam declared its independence from France. The result is a huge party that can be experienced pretty much anywhere in the country.
  • Hanoi’s ‘milk flower’ season: The month of September sees this beautiful and fragrant flower bloom all around Hanoi, its fragrant scent spreading all over the city, a delight for visitors as they explore the city.
