August is about to be the end of summer in Northern Vietnam, the dry season with hot temperatures in the Central Coast, the rainy season with pleasant temperatures in the Central Highlands, and in Southern Vietnam.
In northern Vietnam, August is relatively dry weather with bright sunshine mostly and with lovely or warm temperatures. It is possible that there may be typhoons hitting northern Vietnam in August in which case expect torrential rain in the far northern mountains with possible flash foods and landslides.
The Central Coast has mostly strong sun, dry and hot weather. But the temperatures in this region may be more tolerable than in May, June and July. There may be rain at the end of the month when the rainy season is about to begin.
The Central Highlands are in the rainy season with clouds mostly, daily rain (for 1-4 hours) and pleasant or chilly temperatures. Southern Vietnam also enjoys the rainy season in August with daily rain and pleasant temperatures mostly.
The sea is calm all over Vietnam in August except for the time of typhoon in the North, and sea exploration tours are operable in most places. In case of strong typhoons, the sea can be rough all over Vietnam and travel by sea or by air between the islands and the inland is expected to be disrupted.
It is worth noting that Vietnam is a narrow country with a long coastline and the country is to be affected tremendously by any change in sea temperatures and/or climate change. This is the reason that the weather patterns in Vietnam nowadays may vary from year to year and could be totally different from the norm.
In May, June and July 2025, northern Vietnam and the Central Coast of the country had much more rain than normal and the averaged temperatures were much lower than normal.
In June 2025, there was heavy rain in all over Vietnam. The first typhoon in the East Sea in June 2025 caused torrential rain, flash floods and floods in the Central Coast of Vietnam from Quang Binh Province to Quang Nam Province, which was very different from usual. Northern Vietnam did not have much impact from this typhoon, except for a day to two with high temperatures.
In July 2025, there was heavy rain in all over Vietnam. At the end of July, there were heavy rain and strong gusts of wind in the North, in the Central Coast, in part of the Central Highlands and in southern Vietnam. Several houses in different regions in Vietnam had roofs blown away, trees felled by strong wind....
At the end of July 2025, the western region of Thanh Hoa and Nghe An Provinces suffered from floods and flash floods.
Monsoons in Vietnam in August
In August there are three main monsoons affecting Vietnam:
- The Southeasterly Monsoon which blows mostly in northern Vietnam which causes moist air and pleasant temperatures.
- The Westerly Wind as known locally in the Central Coast of Vietnam, which is actually the Southwesterly Wind coming from the Equator and is a foehn wind, is still weak and tends to influence the Central Coast. This foehn wind is not likely to have impact on part of the Northwest of Vietnam in August as compared to March-April/May period.
- The Southwesterly Wind, which comes from the Equator, is a moist wind and is to cause daily rain and pleasant temperatures in the Central Highlands and in Southern Vietnam.
What to expect from your holidays to Vietnam in August, where to go in Vietnam in August?
Taking the general weather conditions in Vietnam into consideration, for those travelers planning tours to Vietnam or those who are on vacation in Vietnam in August, then there are some notes as follows:
- August may be a good time to travel to the lowland of northern Vietnam as it is relatively dry and the temperatures are more tolerable or pleasant than the other months of summer. In certain year, the end of August could be the time that northern Vietnam starts entering autumn with very pleasant weather patterns.
But it rains and the far northern mountains are more vulnerable to flash floods and landslides, venturing into these places are not recommended in August. In case of a typhoon in northern Vietnam, expect disruption in travel be it inland or between the inland and the islands all over the country.
August is not really a great time for bird watching in northern Vietnam given that migratory species are not present in the region. But August is far better a time for birding in the North compared to the period May-July. Many species may have come out the period of nesting and mating. And thanks to more pleasant temperatures that birds are more gregarious than during hot times.
In the Central Coast of Vietnam, you may still have a good birdwatching experience provided it does not rain. It happens that birding sites in the Central Coast are on high altitudes with very whimsy weather and with high rainfalls, or the biggest averaged annual rainfalls in Vietnam. When it rains, it is not recommended to make trips to these sites as it is potentially dangerous.
Those who go to the sea are to expect calm sea all over Vietnam, except for the time of a possible typhoon in the North. It is more likely that sea exploration tours like scuba-diving, snorkeling... are to be operable.
- The Central Coast of Vietnam is to experience the dry season with warm or hot temperatures. It should be great for beach holidays in the region.
For those who plan trips to the Central Highlands of Vietnam, expect cloudy weather mostly and daily rain which lasts for more or less than an hour. The temperatures are pleasant or chilly in places with high altitudes and pleasant temperatures in places with low altitudes.
Those planning holidays to Southern Vietnam in August, then you are likely to have pleasant temperatures. It is cloudy weather mostly in the South in August.
The beaches in Vung Tau, Long Hai and Mui Ne, Phan Thiet are good options near Saigon Ho Chi Minh City. These beaches may be very crowded at weekends or during public holidays.
Con Dao Islands, Phu Quoc Island are to have cloudy or mild sunny weather with lovely temperatures of 28-31oC. The sea is mostly calm.
