Understanding Vietnam’s September Climate
Vietnam’s elongated geography results in diverse climatic zones, leading to varied weather experiences across its regions in September.

In September, the north begins to transition from the hot, humid summer to the cooler autumn. Temperatures typically range from 24°C to 31°C. While early September may still experience residual rainfall, the frequency decreases as the month progresses, offering clearer skies ideal for exploring Hanoi’s historic sites or cruising through Ha Long Bay.
Central Vietnam (Hue, Da Nang, Hoi An):
Central regions witness an increase in rainfall during September, especially towards the latter half. This period marks the onset of the rainy season, with temperatures averaging between 25°C and 32°C.
