Vietnam weather & when to go: September

Vietnam September weather overview

Wet weather is on the increase in central regions where, towards the end of the month in particular, rain is expected to become more frequent. Conditions in the north are moving in the opposite direction with less rainfall expected, especially as we head towards October. In the mountains of Sapa things are also improving with trekking very much an option once again. Things remain largely unchanged in the south although rainfall does start to decrease as we move into October.

September’s weather in detail

North Vietnam

Hanoi, Halong Bay, Sapa, Ha Giang, Mu Cang Chai, Ninh Binh & Mai Chau

North Vietnam is edging towards the end of its summer although you can still expect plenty of hot weather as well as some rain (avg temp: 28 °C). Towards the end of the month in particular the temperature starts to drop a little and the rainfall becomes less frequent. In the far north the weather in Sapa is starting to improve making trekking an option once again. Late September is a particularly picturesque time of year to visit Mu Cang Chai, as the region's endless rice fields turn a golden colour, ready to harvest.

Central Vietnam

Hoi An, Danang, Hue, Nha Trang, Quy Nhon, Dalat & Central Highlands

The weather in the centre of the country is ready for a change come September and throughout the month rain is on the increase in Hoi An and Hue. Temperatures drop a little and stormy weather is a possibility especially towards the end of the month (avg temp: 28°C). Further south it’s a similar picture as the beaches of Nha Trang start to see an increase in rain. Dalat and the Central Highlands are now very wet making trekking and adventure activities unadvisable, and some of the Phong Nha caves may be off limits due to flooding.

South Vietnam

Ho Chi Minh City, Phan Thiet & Mui Ne, Mekong Delta, Ho Tram & Long Hai, Con Dao & Phu Quoc

The south remains wet although rainfall is decreasing as the month progresses. Temperatures remain high and whilst frequent rain is to be expected you can also still expect plenty of dry and bright daylight hours (avg temp: 28°C).
