July is summer in northern Vietnam, the dry season with hot temperatures in the Central Coast, the rainy season with pleasant or warm temperatures in the Central Highlands, and the rainy season with pleasant or warm temperatures in Southern Vietnam.
In northern Vietnam, July is often the time of sun, clouds, occasional showers, pleasant, warm or hot temperatures.
The Central Coast often has sun or clouds with warm or hot temperatures. The Southwesterly Monsoon (or locally known as the Westerly Wind or Lao Wind) is a foehn wind in this region.
It is worth noting that July is the month of a year that finds the North and the Central Coast of Vietnam with extreme weather: heat wave in the two regions; flash flood and/or flood in the North.
The Central Highlands and southern Vietnam often have heavy rain and mostly pleasant temperatures in July due to the active Southwesterly Monsoon from the Equator.
The sea rough Vietnam in July which is much worse during the time of a typhoon, but sea exploration tours could be operable in most places. There may be typhoons in Vietnam in July which would more likely affect northern Vietnam.
Again, 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.
Recap of Vietnam Weather in 2026
1/ In January of 2026
it is found that the weather patterns were not normal:
- Winter in northern Vietnam was mostly with pleasant temperatures, only two periods with cold temperatures and each was for 4-5 days. The region enjoyed autumn-like weather from October 2025 through January 2026.

- Southern Vietnam had torrential rain for a day in the middle of the dry season.
2/ In February 2026
All of Vietnam enjoyed mostly dry weather with pleasant sun and temperatures. Quite a few plant species started yielding flowers 1 to 1.5 month later than normal. So did the presence of migratory birds.

The lowland of northern Vietnam experienced some rain and mostly dry weather and the extremely moist air was not found in the region as compared to normal.
4/ In April 2026
We did not find the moist air in most of northern Vietnam at the beginning of the month as normal. This is rare.
There was rain in the Central Coast, in the Central Highlands and in southern Vietnam in April which was extremely different from normal as it was supposed to be a dry time.
In Son La, there was hail which destroyed houses and crops.
In the Northwest of Vietnam, there was rain and the temperatures were pleasant mostly. This is not the norm that it is dry and bright sun, high temperatures.
In Long An and Dong Thap Provinces in the Mekong Delta, rain accompanied by strong winds destroyed hundreds of houses.
5/ In May 2026
The North had two brief heat strike each of which lasted 2-3 days in the second and last decades of May 2026. The region also had some weak spells of the Northeasterly Wind in the first and second decades of the month. The second spell of the weak and cool wind was just in time to put an end to the first heat strike in the region.
There were floods in Quang Ninh and Cao Bang Provinces in the second decade of May 2026 which are rare.
Rainy season started in southern Vietnam in the third week of May 2026 which is quite late compared to normal.
Southern Vietnam experienced hot temperatures throughout May. Normally when the region has the rain of the rainy season, then the temperatures turn pleasant or tolerable mostly.
6/ In June 2026
Northern Vietnam suffered from 3 heat strikes in June 2026, each of which lasted for about 3 days. The heat strikes in the second and third decades were extremely bad with high temperatures in the North reaching 40oC and those in the North of the Central Coast reaching over 42oC.
In the second decade of June 2026, there was a brief spell of the cool Northeasterly Wind which put an end to the ongoing carnage of the heat strikes in the North and in the Central Coast. The "Winter Wind" hitting northern Vietnam in June, which is in mid summer, is extremely rare.
For the last 4 days of June 2026, pleasant temperatures returned to northern Vietnam caused by rain across the region, while a heat strike still went on to most of the Central Coast of the country.
There was a flood in Cao Bang in the last decade of June 2026 which is not usual.
The Central Highlands and southern Vietnam had rain and heavy rain for most of June and the two regions enjoyed mostly pleasant temperatures. Southern Vietnam had some days with intense sun and warm temperatures.
There was no typhoon affecting the inland of Vietnam in June 2026.
Monsoons in Vietnam in July
In July there are two main monsoons affecting Vietnam:
- The Southeasterly Monsoon which blows mostly in northern Vietnam which causes moist air and pleasant temperatures.
- The Southwesterly Monsoon which comes from the Equator and which causes daily short-lived rain in the Central Highlands and in southern Vietnam.
- The Westerly Wind, which is actually the Southwesterly Wind blowing through Myanmar, Laos, Thailand before hitting the Central Coast of Vietnam, is a foehn wind. This wind causes brighter sun, dry air and hot temperatures in the affected regions.
The Terrain and Climatic Factors Impact on the Weather in Vietnam in July
1/ The mountain ranges in Vietnam often runs from the northwest to the southeast
Most mountains in Vietnam follows this direction with the exception of the Truong Son Mountain Range which runs from the North of the Central Coast to the west of the Central Highlands, or along the north-south axis.
This factor helps to facilitate the blow of the Southesterly Monsoon and the Southwesterly Monsoon. The Southwesterly Monsoon is known locally as the Lao Wind or Westerly Monsoon in the North West and the Central Coast of Vietnam. This wind is a foehn wind in the Central Coast of Vietnam. This wind is also the foehn wind in the Northwest of Vietnam from March to May.
But later after May in the Northwest of Vietnam, the Southwesterly Wind (or Weasterly Wind) helps to accumulate humidity and clouds to the region and helps to cause heavy rain. It is because of high humidity in the whole of northern Vietnam and it is the direction of the mountains that helps to push humidity and to form clouds over the Northwest, hence heavy rain.
2/ Hot Air Regions in the Troposphere, Air Troughs, Tropical Convergence Zone, Clockwise Cyclonic Circulation (by Storms or Tropical Depressions)
Because of high humidity in the whole of northern Vietnam in July caused by the active Southeasterly Monsoon, Southwesterly Monsoon facilitated by the direction of the terrain (and the mountains), it often rains more in northern Vietnam in July.
In case of a typhoon or tropical depression, the clockwise cylonic circulations help to push humidity and clouds over the North, hence heavy rain in the whole region. This often in combination of other favorable factors by the monsoons and terrain creates synergy for heavy rain in the North, be it the Northwest, the Northeast or the lowlands (including the Red River Delta.
The Central Coast of Vietnam is under impact of the Southwesterly Monsoon. But this wind, after blowing over the Truong Son Mountain Range (running north-south in the west of this region), becomes a foehn wind, hence dry air and high temperatures. But in case of a typhoon or tropical depression, expect heavy rain and worse torrential rain, especially in the region to the west.
The Central Coast may also under impact of the often hot air region in the troposphere to the west of Vietnam.
The Southwesterly Monsoon is more active and it causes heavy rain in the Central Highlands and in southern Vietnam in July.
There are often air troughs or tropical convergence zones with the axis across northern Vietnam in July and they help to accumulate clouds that cause heavy rain to the region.
What to expect from your holidays to Vietnam in July, where to go in Vietnam in July?
Taking the general weather conditions in Vietnam into consideration, for those travelers planning tours to Vietnam or those who are on holiday in Vietnam in July, then there are some notes as follows:
- July is a fine time to visit Vietnam given the dry weather mostly: July is not known for long-lasting rainy weather across the country. You are to get pleasant temperatures in the Central Highlands and in southern Vietnam, but hot temperatures in the Central Coast and northern Vietnam.
In northern Vietnam, July is not a good time to go on trekking tours, biking adventures to the far northern mountains. This is because of the often high temperatures across the region and/or heavy rain (which could cause floods or flash floods in the far northern mountains, floods in the lowland).
All trips through the lowland of the North are more likely to experience beautiful weather with bright sunshine, pleasant or warm temperatures. This does not apply to the time when there is a typhoon hitting the region.
July is not a good time for birding in the North, in the Central Coast of Vietnam. It is more likely better experiences to go on birding trips in the Central Highlands and in southern Vietnam this month, but there is daily rain which could last from an hour to a few hours each day.
Most local resident birds in Vietnam are in the period of nesting and mating. Food is mostly abundant given frequent rain and birds are not desperate to come out for food everyday.
It is more likely that sea exploration tours like scuba-diving, snorkeling... are to be operable in all places, except for the time of a typhoon.
The beaches in the Central Coast from Quang Binh to Nha Trang: Nhat Le, Cua Viet, Da Nang, Hoi An, Quang Ngai (Sa Huynh), Quy Nhon, Tuy Hoa, Doc Let, Nha Trang... are to offer great beach vacations.
The beaches in Vung Tau, Long Hai and Mui Ne, Phan Thiet are good options near Saigon Ho Chi Minh City.
Con Dao Islands, Phu Quoc Island are to have sunny weather with lovely temperatures of 27-32oC.
The sea could be rough in July, but island vacations or sea exploration tours are to be operable. But, a typhoon in July could cause disruption to boat trips and flights between the inland and the islands across Vietnam, and it has happened that several thousand tourists are stranded on islands across the country due to typhoons.
