Vietnam Weather September Overview

September marks the beginning of autumn and is one of the most beautiful months to travel to Vietnam thanks to its comfortable climate.

Along with the decrease in rainfall in both the North and South regions, September weather is said to be very beautiful and suitable for travelling almost anywhere in the country.

Weather in North

September is considered one of the fantastic times to visit North Vietnam. It is the end of summer with light occasional showers and mostly clear sky. North Vietnam’s average temperature in September is about 28°C, and you can expect cooler temperatures in the high and far mountainous areas such as Sapa or Mu Cang Chai. 

Thanks to the ideal weather, late September is a particularly picturesque time of year to see the golden rice fields in North Vietnam. During this month, the rice turns from yellow-green to golden colors which is the sign of harvest time. These dreamy rice terraces are a splendid sight to behold, especially for photographers. 


Weather in Central

Unfortunately, September is the rainy season in Central Vietnam which is not really suitable for any tourism activities. Throughout this month, rain is on the increase in the central region’s cities like Hoi An, Hue, and Da Nang, Dalat, and the Central Highlands. Thanks to the unstoppable rains, September weather in Central Vietnam is really chilly; however, it’s also wet and there might be storms and floods toward the end of this month. If you insist on visiting Central Vietnam during September, Mui Ne (Phan Thiet) is the most promising destination as these places have less rain than other places in the region.


Weather in South

In September, although South Vietnam remains wet, it seems like the rainy season here is coming to an end as the rainfall decreases as the month progresses. As a result of the hot weather from last summer and also the tropical climate, the September temperatures in South Vietnam can be high (avg temp: 28°C), but the rain can make you feel better. It is also the flooding season in Mekong Delta, which surprisingly is a very beautiful time here and suitable for any water activities.

Mekong Delta

Although September is the rainy season in Mekong Delta (South Vietnam), it is also the time that you can see the unique beauty of this area that is hard to find anywhere else. As it usually rains in this month, the water level in rivers and fields rises thrivingly, creating the annual floating water season which will last from September till November.

More water brings a better life for plants and creatures in the Mekong Delta; therefore, September - November is the best time to see the natural beauty of this area. You should spend time visiting national parks and natural reserves here to admire the precious birds (some kinds even in the Red Book) and the wild beauty of Mangrove forests. 

In addition, the Mekong Delta is home to many fruit orchards which provide fresh tropical fruits all year round. You should also visit an orchard to taste the delightful fruits here at a very cheap price. Cai Be Orchard (Tien Giang Province), Cai Mon Orchard (Ben Tre Province), Vinh Long Orchard are among the best orchards in the Mekong Delta where you can find a variety of fruits through four seasons of the year, and some outstanding types are Nam Roi Pomelo and Binh Hoa Phuoc rambutan, and a wide selection of other fruits, like durian, longan, tangerine, mango, etc.
