Southern Vietnam climate
Before looking at the specific weather conditions for August, it’s important to understand the overall climate in southern Vietnam. The region experiences a tropical monsoon climate, meaning warm temperatures all year and two main seasons:
- Dry season (November – April): Features minimal rain, lower humidity, and clear skies.
- Rainy season (May – October): Brings increased humidity and short but intense rain showers, mainly in the afternoon.
Travel Tip: The climate in southern Vietnam follows a different pattern than the rest of the country. While northern Vietnam continues its hot summer, and central Vietnam begins to see slightly more rain compared to earlier dry months, the south remains warm with regular rainfall.
Weather in South Vietnam in August
August remains firmly within the rainy season, bringing high temperatures, very high humidity, and frequent rainfall. Daytime temperatures range from 28–33°C (82–91°F), with nighttime temperatures between 24–27°C (75–81°F). The heat is consistent, but the high humidity makes it feel even warmer.
Rainfall is heavy, averaging 200–350 mm (8–14 inches). Humidity levels are among the highest of the year, staying between 85–90%.
Rain is common, usually occurring in short, intense bursts in the afternoon or evening. Some days see prolonged periods of cloud cover, but there are still sunny intervals. Rain rarely lasts all day, and heavy showers are often followed by clear skies.
Beach conditions in South Vietnam in August
From the floating markets of the Mekong Delta to the lively streets of Ho Chi Minh City, South Vietnam has a lot to explore—but for many visitors, Phu Quoc, Con Dao, and Mui Ne are the perfect places to unwind by the beach.
August is not a good month for the beach in Phu Quoc and Con Dao, as heavy rainfall and rough seas are common. Swimming conditions are often unsafe due to strong waves and poor visibility, and boat trips can be affected by the weather. Mui Ne has less rain than the islands, but humidity is high, and occasional showers occur.
Travel Tip: For a better beach experience in August, central Vietnam (Da Nang, Hoi An, Nha Trang) offers dry, sunny weather and excellent sea conditions.
Is August a good time to visit South Vietnam?
August is an okay month to visit South Vietnam, but it is one of the wettest months. Rainfall is frequent, but like in previous months, it mostly comes in short, intense bursts rather than all-day storms. The upside is that the Mekong Delta is at its most vibrant, with full waterways and an abundance of fresh fruit. Ho Chi Minh City is still an option for sightseeing if you plan around the rain. While beach conditions are not at their peak, they can still be enjoyable on drier days. If you don’t mind occasional rain and prefer lush landscapes, August can still be worth considering.
Best places to visit in August
August is in the middle of the rainy season in South Vietnam, meaning frequent downpours and high humidity. However, travel is still possible, and some destinations offer unique seasonal highlights. Below, we highlight some of the best places to visit this month. If you want a complete list of must-visit places in South Vietnam, be sure to check out our full travel guide: Places to Visit in South Vietnam.
1. Mekong Delta – Peak of the Fruit Season
August is one of the best months to visit the Mekong Delta, as the fruit season reaches its peak. Orchards are filled with ripe tropical fruits such as durian, rambutan, and mangosteen, making it a great time for food lovers. Despite the rains, boat trips through the floating markets and canals remain a unique experience, as showers are typically short-lived. The lush landscapes and high water levels make for scenic river journeys, allowing travelers to explore the heart of Vietnam’s agricultural life.

2. Con Dao – Peak of Turtle Nesting Season
August is a great time to visit Con Dao for those interested in wildlife. The island is at the peak of the turtle nesting season, where visitors can witness sea turtles laying eggs on the beaches. While there are frequent tropical rain showers, they are usually short and do not significantly impact outdoor activities. Diving remains possible, though the sea can be rough at times. Beach conditions are unpredictable, making this month more suitable for nature and wildlife enthusiasts rather than those looking for a traditional beach holiday.

3. Ho Chi Minh City – Rainy but Vibrant
Ho Chi Minh City remains an exciting destination in August, despite the frequent rain. Downpours are usually heavy but short, and they often clear up quickly, allowing visitors to explore the city’s attractions. Indoor activities such as visiting the War Remnants Museum, Reunification Palace, and bustling shopping malls are ideal for escaping the afternoon rains. The café culture thrives in the rainy season, making it a great time to enjoy a traditional Vietnamese coffee while watching the rain pass by.

4. Mui Ne – Unpredictable Weather but Possible Dry Spells
August remains within the rainy season in Mui Ne, bringing occasional heavy showers and high humidity. While not the best time for a dedicated beach holiday, there are still sunny periods where visitors can explore the Red and White Sand Dunes, take a walk along the Fairy Stream, or experience the local fishing villages. The rain tends to be short-lived, meaning you may still get opportunities to enjoy outdoor activities. Accommodation prices are lower than during the peak season, making it a budget-friendly option.

5. Phu Quoc – Wet and Stormy
Phu Quoc is not an ideal destination in August, as it experiences heavy rain and strong winds. Rough sea conditions limit water activities such as snorkeling and boat trips, and the beaches are not at their best. However, for travelers looking for lower prices and fewer tourists, Phu Quoc offers significant discounts on accommodation. Exploring the island’s waterfalls, such as Suoi Tranh, can be a rewarding experience as they become more impressive with the increased rainfall.

Events and holidays in August
August in southern Vietnam is centered around Vu Lan Festival (Hungry Ghost Festival) if it falls this month. This Buddhist festival is the most significant spiritual event of the month, deeply tied to ancestor worship and acts of kindness. Other than that, there are no major national holidays, making it a good time to explore cities and natural destinations without peak-season crowds.
Vu Lan Festival (Hungry Ghost Festival) (Lunar July 15; falls in August most years)
The Vu Lan Festival is one of the biggest Buddhist celebrations in Vietnam, dedicated to honoring ancestors and helping lost souls find peace. Families visit pagodas to pray for their deceased relatives, offer food, flowers, and incense, and sometimes participate in charity acts. Some people also wear red or white roses—red if their mother is alive, white if she has passed away.
For travelers: If you’re in Ho Chi Minh City, visit Vinh Nghiem Pagoda or Giac Lam Pagoda, where large ceremonies are held. The Mekong Delta is also an interesting place to experience Vu Lan, as Khmer and Vietnamese Buddhists both observe the festival in different ways. Travelers should be respectful when visiting temples, and if you’re interested in Buddhist culture, this is one of the best times to witness a deeply spiritual side of Vietnam. Many local restaurants may also serve more vegetarian dishes around this time.
