Weather Overview
In Vietnam, September marks a critical transition from summer to autumn. In the northern regions, autumn begins with a noticeable decrease in rainfall, while the central and southern areas enter their peak rainy season, featuring a heightened risk of storms or typhoons. Despite this, September remains an excellent time to explore Vietnam for various reasons.
September signifies the end of the student summer holidays, leading families back to their routines. Consequently, popular tourist destinations experience lower visitor levels. Whether you are an outdoor adventurer, a city explorer, or a relaxation-seeking traveler, Vietnam in September offers numerous opportunities.
Temperature and Humidity
Although storms from the previous month may bring uncomfortable weather, they also help to cool temperatures for September. In Hanoi, the average temperature ranges from 24 to 31°C, with humidity levels averaging around 80%. Northern mountain regions share similar humidity but enjoy slightly cooler temperatures, typically between 17 and 27°C.
The southwest monsoon from the eastern sea leads to substantial rainfall in the central regions. Be sure to monitor the forecasts if you plan to visit the central coastal areas.
Like August, September remains part of the rainy season in Ho Chi Minh City and the Mekong Delta, characterized by consistently pleasant temperatures below 30°C, though with approximately 25 rainy days. The great news is that rain showers are often brief, giving way quickly to sunshine before you can even open an umbrella.
