Climate and region of Mekong Delta
The Mekong Delta, located in southern Vietnam, is a fascinating region where the Mekong River branches into a complex network of canals, wetlands, and lush farmland. Known for its floating markets, traditional villages, and diverse wildlife, the delta offers a unique glimpse into a way of life deeply connected to the waterways. Key destinations include Can Tho, My Tho, Ben Tre, Chau Doc, Vinh Long, and Ca Mau, each with its own cultural and natural attractions.
The Mekong Delta has a tropical monsoon climate, which consists of two distinct seasons:
- Dry season: December – April
- Rainy season: May – November
By September, the rainy season is still in full swing, ensuring that rivers and canals remain at high water levels. The countryside is at its greenest, and this is also the time when floodplains replenish, creating a vibrant ecosystem that supports agriculture and fishing.
Travel Tip: If you’re visiting multiple regions in Vietnam, keep in mind that the climate varies. In September, the Mekong Delta experiences its peak rainy season, while central Vietnam enters the start of its wet season, and northern Vietnam transitions from summer to autumn, with milder temperatures and occasional rain showers.
Weather in Mekong Delta in September
September is characterized by warm temperatures, high humidity, and frequent rain showers. Daily temperatures range from 24°C (75°F) in the early morning and evening to around 31°C (88°F) at midday.
Rainfall remains heavy, averaging 200–300 mm (8–12 inches) throughout the month, with 15–22 rainy days. However, like other months in the rainy season, downpours are often short and intense, usually occurring in the late afternoon or evening. Despite the wet conditions, 5–7 hours of sunshine per day allow for outdoor activities during dry periods.
September is the late phase of the rainy season, meaning river levels are at their highest. This benefits boat travel, making it easy to navigate even the smaller canals. However, some rural areas may experience temporary flooding, and muddy roads can make travel more challenging in certain locations.
Is Mekong Delta worth visiting in September?
Yes, September can still be a good time to visit the Mekong Delta, especially for those interested in nature, photography, and experiencing local life during the high-water season. The landscape is lush, the rivers are at their fullest, and this is the best time to see the unique “floating season”, when water levels rise and transform the scenery.
One of the highlights of visiting in September is the abundance of fresh seafood and tropical fruits, as well as the vibrant floating markets that remain active despite the rain. Additionally, there are fewer tourists, making for a more peaceful and authentic experience.
While heavy rain showers can occasionally disrupt plans, those who plan their activities around the weather and embrace the tropical conditions can still enjoy a memorable visit to the Mekong Delta in September.
Travel tips & best things to do in September
September is one of the wettest months in the Mekong Delta, but that doesn’t mean it’s a bad time to visit. This is the peak of the flood season, transforming the region into a beautiful water world where rivers are at their fullest, boat trips are easier, and floating markets are at their liveliest. While rain showers are frequent, they are usually short-lived and followed by clear skies. If you embrace the rainy season, September offers unique travel experiences, including lush landscapes, abundant fish and seafood, and a glimpse into the annual flood season lifestyle of the local people.
The Floating Season – A Special Time for Boat Trips
September is part of the Mekong Delta’s “floating season” (Mùa Nước Nổi), a time when water levels are at their highest, making boat trips even more scenic and expansive. Many areas that are not navigable in the dry season become accessible, making this an excellent time to explore hidden canals and floating villages.
Best Places for Boat Trips in September:
- Tra Su Cajuput Forest (An Giang) – The flooded forest is at its most beautiful, with boats gliding through the submerged trees.
- Long Xuyen Floating Market (An Giang) – One of the most authentic floating markets, where locals rely on boats to move around.
- Tan Lap Floating Village (Long An) – A serene, off-the-beaten-path destination where houses and walkways seem to float on the water.
Travel Tip:
- Opt for small paddle boats or sampans to navigate the narrow, flooded waterways.
- Book a morning boat trip (6:00–8:00 AM) to enjoy the best light and avoid afternoon rain showers.
- Bring a light rain jacket or poncho—rain may come unexpectedly but won’t last long.
Floating Markets – At Their Most Active
September is one of the best months to experience the Mekong Delta’s floating markets, as the high water levels allow for smooth navigation and an increase in trading activity. Farmers and fishermen sell their goods directly from boats, and the markets are full of fresh seafood, fish, and seasonal produce.
Best Floating Markets to Visit in September:
- Cai Rang Floating Market (Can Tho) – The largest and most famous market, best visited at sunrise.
- Phong Dien Floating Market (Can Tho) – A smaller, more traditional market with fewer motorized boats.
- Nga Nam Floating Market (Soc Trang) – A unique five-way floating market where boats come from all directions.
Travel Tip:
- Arrive before sunrise (5:30 AM) for the most authentic experience.
- Try local breakfast dishes, such as hủ tiếu (noodle soup) or bánh mì (Vietnamese sandwich) served from floating kitchens.
Fish & Seafood at Its Best
With rivers overflowing, September is the peak fishing season in the Mekong Delta, and the markets are full of freshwater fish, shrimp, and other seafood. Many villages rely on fishing nets, floating fish farms, and traps, creating a unique way of life that visitors can experience firsthand.
Best Places to Experience Fishing & Fresh Seafood:
- Chau Doc Floating Fish Farms (An Giang) – Visit floating houses where locals raise catfish and basa fish for export.
- Dong Thap Province – Try hotpot made with Linh fish (cá linh) and water lilies, a signature dish of the floating season.
- Can Tho Night Market – A great spot to sample fresh grilled seafood, shrimp pancakes, and Mekong-style clay pot fish.
Travel Tip:
- If you want a hands-on experience, join a local fishing tour, where you can help set traditional fish traps.
Khmer & Cham Festivals – A Cultural Experience
September is an important month for Khmer and Cham communities in the Mekong Delta, with several major religious festivals taking place. These events offer an incredible opportunity to witness local traditions, including boat races, ox races, and colorful temple celebrations.
Key Festivals in September:
- Sene Dolta Festival (Khmer Ancestral Celebration, Soc Trang & Tra Vinh) – A Buddhist festival where Khmer families honor their ancestors with ceremonies and feasts.
- Chau Doc Cham Festival (An Giang) – A spiritual event at Chau Giang Mosque, featuring traditional Cham music and Islamic prayers.

Travel Tip:
- Visit Khmer pagodas in Tra Vinh or Soc Trang to see traditional celebrations and processions.
- If in An Giang, check for the Ox Racing Festival dates, as they vary each year.
Cycling – Only for the Early Mornings
September is not the best month for cycling, as heavy rains can turn rural roads into mud. However, short rides in the early morning or on paved paths can still be enjoyable.
Best Cycling Routes for September:
- Ben Tre’s coconut groves – Shaded roads provide a more comfortable ride.
- Vinh Long & An Binh Island – Beautiful countryside with fruit farms and river crossings.
Travel Tip:
- Avoid afternoon cycling, as rain showers are most likely after midday.
- Stick to short routes and paved roads, as dirt paths can be flooded or muddy.
Beach Escapes – Better to Fly Than Take a Ferry
Since September is not a great month for beaches in the Mekong Delta due to rough seas and heavy rains, it’s better to fly to a drier beach destination.
Best Options for a Beach Extension from the Mekong Delta:
- Can Tho → Da Nang (Direct Flight) – The beaches in Hoi An and Da Nang start improving in late September.
- Can Tho → Phu Quoc (Flight or Ferry) – Phu Quoc is rainy but may have occasional sunny days.
Travel Tips for September in the Mekong Delta
- Expect heavy rain and high humidity, but showers are usually short and followed by clear skies.
- Visit floating markets and do boat trips in the morning, as afternoon rains are unpredictable.
- Try local specialties of the flood season, like Linh fish hotpot with water lilies.
- Check festival dates, as Khmer and Cham celebrations offer a rare cultural experience.
