What’s the weather like in Vietnam in September?It’s one of the wettest months of the year in this amazing country in south east Asia, but that shouldn’t put you off visiting. The Vietnam weather in September is also very warm and packed with sunshine, which means you can take in the full wonder of Vietnam’s incredible beaches, cities and natural landscapes.
Geographical influencesThe main influence on the weather in Vietnam in September are the south west monsoon rains. These reach the country from the Indian Ocean and bring warm and humid clouds. Rainfall is higher in the north of Vietnam, especially on the mountains, but Ho Chi Minh in the south also has tropical downpours which are typical for Asia at this time.
AveragesYou’ll make the most of the warm weather in Vietnam during your stay. The average daytime temperature will be around 24°C in September, but expect this to rise by four or five degrees on hotter days in the south. The humidity level will be very high, at an average of 94%, so you’ll need to carry water with you as you tour the pretty beaches and towns. Visitors love the sunshine in September. Ho Chi Minh can boast up to 11 hours each day with the sun not setting until around 6pm. If you’re relaxing by the coast, you’ll be tempted to cool off in the South China Sea. The water will have a temperature around a balmy 27°C at this time. In the south of Vietnam the rainfall could be over 200mm this month.
