Vietnam in August is a month of contrasts: it is the wettest month in Hanoi (274 mm, 10.8 in) and the rainy season in the south, but the centre (Hue, Da Nang, Hoi An) stays hot, sunny and fairly dry. A trip in August is therefore possible, provided you build the itinerary around the centre and accept the humid heat.
Here is the weather in Vietnam in August region by region, the itineraries that work and the precautions to take. To compare with the rest of the year, see our page on the best time to visit Vietnam.

Vietnam stretches for more than 1,600 km (994 mi) and its regions do not follow the same calendar. In August, the north and the south are in the full summer monsoon, with more than 200 mm (7.9 in) of rain in the month and muggy heat. In the south, rain falls mostly as short afternoon showers. The centre is out of step: its dry season runs from February to August, and its heavy rains only arrive from September. August there is the end of the good season, with more frequent thunderstorms than in July. To see how the situation reverses in autumn, see our page Vietnam weather in October.
Tropical storms matter at this time of year: the UK FCDO says the tropical storm season runs from May to November and that cyclones affecting the eastern coastal regions bring strong winds, heavy rainfall and flooding and can disrupt transport (GOV.UK, updated 21 September 2026). Follow the advice of local authorities.
Region by region
- North (Hanoi, Halong Bay, Ninh Binh): hot, very humid and rainy. Halong Bay is luminous between showers, but this is the period when typhoons can cancel cruises. Very green rice-field landscapes.
- Northern mountains (Sapa, Ha Giang): cooler (about 23 °C, 73 °F, in the afternoon in summer in Sapa), but very wet from May to August; muddy trails and roads sometimes cut off.
- Centre (Hue, Da Nang, Hoi An): the best option of the month; warm sea, the beaches of Da Nang and An Bang, the old town of Hoi An.
- South (Ho Chi Minh City, Mekong Delta, Phu Quoc): can be visited despite the showers; Phu Quoc is very rainy from June to September and is not suited to a beach stay.
Which itinerary in August?
| Itinerary | Feasibility in August | Advice |
|---|---|---|
| Centre only (Hue, Hoi An, Da Nang) | ✅ The best option | Combine heritage and beach; sightsee early in the morning |
| Centre + Hanoi | ⚠️ Possible | Keep a few spare days for Halong Bay |
| Full north-to-south circuit | ⚠️ Possible with reservations | Rain in the north and south; favour domestic flights |
| Beach in the south (Phu Quoc) | ❌ Avoid | Prefer the beaches of the centre |
Things to do in Vietnam in August
- Hoi An: old town, workshops, cycling through the rice fields, An Bang beach; the lantern evening takes place every month at full moon.
- Hue: the imperial citadel and the emperors’ tombs, to be visited early because of the heat.
- Da Nang: urban beaches, the Marble Mountains, the Hai Van Pass between Hue and Hoi An.
- Hanoi and Ninh Binh: the Old Quarter, Hoan Kiem Lake, the very green karst landscapes of Ninh Binh.
- Mekong Delta: floating markets and canals, with a plan B in case of showers.
What is best avoided in August
- A Halong Bay cruise without a spare day: if a typhoon alert is issued, departures can be cancelled. The UK FCDO also advises considering safety standards carefully before an overnight boat trip on Halong Bay, as overcrowding and poor safety standards have led to accidents (GOV.UK, updated 21 September 2026)
- A beach stay on Phu Quoc
- Long hikes in Sapa or Ha Giang in the middle of the monsoon
- Tight connections between domestic flights
Events in August
| Period | Event | Where |
|---|---|---|
| Every month, at full moon | Lantern night | Hoi An |
| 15th day of the 7th lunar month (August or September depending on the year) | Vu Lan, a festival dedicated to parents and ancestors | Pagodas across the country |
| 2 September | National Day (public holiday, strong demand just after August) | Nationwide |
Crowds and prices
August combines the northern-hemisphere summer holidays with the beach season in central Vietnam: Hoi An and Da Nang are very busy and prices are high. In the south, the rainy season makes prices milder. For international flights in August, book several months ahead.
What to pack

If August does not suit you
Neighbouring months: July is slightly drier in the centre (95 mm, 3.7 in in Hue); September marks the start of the heavy rains in the centre and the wettest month in the south, but the rice fields of the north turn golden. For a full circuit, March-April remains the best window. The previous month, in the middle of the dry season in the centre, is covered on our page Vietnam weather in July.
