General Weather Patterns in Vietnam in September
All of the North of Vietnam is to have prevalent Southeasterly Wind which brings inland moisture, hence rain and more pleasant temperatures in the whole region. There are occasional typhoons to the North which may cause incessant an torrential rain to the region which may pose serious threats of landslides, rockslides and flashfloods in the mountains.
It does not often happen but there may be sometimes Northeasterly Wind in September which brings about short-lived rain followed by beautiful days with mild sun, breezes and extremely pleasant temperatures. The temperatures in Northern Vietnam are 26-33oC in the lowlands in the first half of September and 23-29oC in the second half of the month.

But rain and lower temperatures tend to be the case in the second half of September. The region may be under impact of a typhoon in September but the chances are not high.
The Central Highlands and South of Vietnam still come under influence of the Southwesterly Wind which causes daily rain. It tends to rain more in these two regions in September and it is mostly cloudy days in the month. The temperatures are 21-28oC in the Central Highlands, 26-32oC in Southern Vietnam.
Adventure Travel, Nature Tours, Bird Watching Tours, Photo Tours in Vietnam in September
1/ Hiking Tours, Mountain Trekking Tours
September is generally a good time for adventure tours in Northern Vietnam, except for the period the region is under impact of a typhoon which may last for 2-3 days each. It is fall in the North and the weather is mostly favorable : dry, breezy. Those embark on mountain trekking tours are to be awarded with beautiful clouds on high mountain peaks. From the end of September maple trees on high mountains change to yellow or red colors which are just breathtaking !
September is not a great time for hike tours in the Central Highlands given it is high rainy season.
2/ Adventure Tours
Northern Vietnam is a great place for general adventure tours in September except for the time when it is under impact of a typhoon. Traveling in the North this month you’ll get pleasant temperatures, breezes and mild sunshine.
Though September is not a great time for general adventure tours in the Central Coast, in the Central Highlands and in Southern Vietnam, but it is not a bad time either. In the Central Highlands and Southern Vietnam you have rain alterated by clouds in a day. In the Central Coast, rain is often alternated by clouds or sun and it is not yet continual rain day after day yet, except for the period the region is under impact of a typhoon.
3/ Birding Trips and Bird Watching Tours
September is the time that most migratory bird species are not present in national parks and nature reserves in Vietnam, and bird parks in the country are not busy with wildlife. But the resident birds are more active than in the summer and so it is fine to go on birding tours in September.
Birding sites in Vietnam in September :
- Cuc Phuong National Park (Ninh Binh) : mostly resident birds (Black Bird, pittas, magpie, pipit.
- Van Long Nature Reserve (Ninh Binh): storks and water fowls.
- Xuan Thuy National Park (Nam Dinh) : mostly storks, migratory species are not present yet.
- Bach Ma National Park (Thua Thien – Hue) : if it is dry then travel to this national park is possible and you should get some good time birding here. If it rains, it gets foggy and traveling to the national park is not recommended given the road conditions. Besides, it gets quite foggy anyway and bird-watching is difficult.
- Da Lat (Lam Dong, Central Highlands) : There are days with mostly clouds and birding at Da Lat is a good experience. Else, it’d be too wet and foggy.
- Cat Tien National Park (Dong Nai, Southern Vietnam) : Birding is still great when it does not rain.
4/ Family Tours
Generally speaking, families should have a good time traveling in Vietnam in September. If you travel with babies, then it is advised to check the weather in advance carefully before each destination then. The reason is because September is quite an unpredictable time in terms of the weather : it is the transitional time between seasons, it is typhoonal season still in Northern Vietnam and part of the Central Coast.
5/ Island Holidays
You are to have nice temperatures on vacation in Vietnam in September. If it is the time of a typhoon, then you will have a great time on the islands in Northern Vietnam (Co To Island, Quan Lan Island, Cat Ba Island).
September is not a recommended time to travel to islands in the Central Coast (Cu Lao Cham in Hoi An or Ly Son Island in Quang Ngai). But it is still fine to travel to the islands in the South of the Central Coast (Phu Quy Island in Binh Thuan).
Those who travel to the islands in Southern Vietnam like Con Dao Islands ( Ba Ria – Vung Tau) and Phu Quoc Island (Kien Giang) should expect more days with clouds and rains, nice temperatures.
6/ Beach Vacations
If you are lucky then you can get some days in the South of the Central Coast of Vietnam with lovely sunshine and your beach holidays should be good. But it may be more likely that it is more cloudy days or rainy days. The beaches in the Central Coast you should give it a try if you are deperate for a beach break : Nha Trang (Khanh Hoa Province), Ninh Chu (Ninh Thuan Province), Mui Ne (Binh Thuan Province).
If you travel to Southern Vietnam then you may try Vung Tau Beach, Long Hai Beach and Ho Tram Beach (all in Ba Ria-Vung Tau Province).
