September is a fascinating month to travel in Vietnam. The country stretches over 1,600 km from north to south, so the weather shifts dramatically between regions. You’ll find everything from cool mountain breezes in the north to tropical downpours in the south. With the right planning, September can be one of the most rewarding times to visit.

Hanoi welcomes September with cooler days (24–32°C) and occasional afternoon showers. It’s a great time to stroll around Hoan Kiem Lake, visit the Old Quarter, and enjoy local street food.
For nature lovers, Sapa offers crisp mountain air (18–25°C), foggy mornings, and green terraced rice fields — perfect for trekking and photography. In Ha Long Bay and Ninh Binh, the weather is warm (26–32°C) with light rain, but boat cruises and cave explorations remain top highlights.
