What you gain in September
- ↑September is the cheapest month for accommodation — luxury riverside properties available at budget rates
- ↑Visitor numbers drop sharply: the Ancient Town and cooking schools have genuine availability
- ↑Dramatic river and sky photography: the Thu Bon swollen and fast, dramatic monsoon cloud formations
What you sacrifice
- ↓272mm of rain is the beginning of the worst weather period: heavy daily rainfall with little predictability
- ↓Typhoon risk at its peak — named storms regularly track across central Vietnam in September, with trip-cancelling potential
- ↓An Bang Beach completely unusable: rough seas, dangerous surf, most beach bars shuttered
