Northern Vietnam: A Golden Canvas of Autumn
In Northern Vietnam, cities like Hanoi, Ha Giang, and Mu Cang Chai begin to shift from the tail end of the rainy season to early autumn. The weather becomes noticeably more pleasant, with cooler temperatures ranging from 23°C to 28°C. As the month progresses, the sticky humidity of summer gives way to a refreshing cool breeze, making it an ideal time for walking tours, street food excursions, and cultural explorations.
September is the harvest season in Northern Vietnam.
This time of year is particularly breathtaking in rural areas. In places like Mu Cang Chai, September marks the peak of the harvest season. Rice terraces shimmer in a golden colour, creating some of the most amazingly magnificent scenery in the country. The weather is generally cooperative for treks and nature photography, although brief showers may still appear—especially in the first half of the month.
Central Vietnam: Sun-Kissed Days with Tropical Showers
The central regions of Vietnam, including Da Nang, Hoi An, and Nha Trang, experience a more humid and unpredictable September. Temperatures hover between 24°C and 34°C, and the region still sees a fair share of rain. However, showers are usually short-lived and occur in the late afternoon, allowing plenty of time for sightseeing and beach relaxation during the day.
Afternoon is the best time for sightseeing and beach relaxation during the day.
While the coastlines are dotted with visitors year-round, September is considered an off-peak season, meaning fewer tourists and more space to enjoy the region’s charm. Whether it’s strolling through the lantern-lit streets of Hoi An or soaking up the sun in Nha Trang, travellers can still find stretches of bright daylight hours and the occasional spell of pleasant weather. Keep in mind, though, that heavier rainfall may increase toward the end of the month as the region edges closer to its storm season.
Southern Vietnam: Rains Ease into Tranquillity
Southern Vietnam, which includes Ho Chi Minh City, the Mekong Delta, and Mui Ne, remains in the throes of the rainy season during early September. Expect frequent tropical showers, often in the form of quick downpours in the afternoon or evening. However, the good news is that as the month progresses, rainfall decreases, paving the way for more consistent dry days and improved travel conditions.
Mui Ne is a hidden gem of the South Coast.
Temperatures in this region stay relatively high—averaging around 27°C to 30°C—but without the scorching heat of mid-summer. With less rainfall and fewer crowds, September becomes a more accessible time to explore the south’s many gems, from the floating markets of the Mekong to the cultural treasures of Ho Chi Minh. As always, it’s best to pack rain gear, especially for boat tours or countryside excursions, just in case the skies decide to open.
Festivals and Events
Travelling to Vietnam in September means more than just scenic landscapes and shifting weather—it’s also a month rich with national pride and traditional festivity. Two major cultural events take centre stage during this time: Vietnam National Independence Day and the enchanting Mid-Autumn Festival (Tet Trung Thu). Each offers a unique window into the country’s spirit, history, and enduring sense of community.
Vietnam National Independence Day: A Celebration of Pride
September 2nd marks Vietnam National Independence Day, commemorating the day in 1945 when President Ho Chi Minh read the Declaration of Independence at Ba Dinh Square in Hanoi, founding the Democratic Republic of Vietnam. This national holiday is one of the most significant days in the Vietnamese calendar, and it’s a fantastic opportunity for travellers to witness patriotism and pageantry in full display.

In the capital city of Hanoi, the streets come alive with red banners, flags, and decorative lights. Thousands gather around Ba Dinh Square, near the Ho Chi Minh Mausoleum, to attend ceremonial parades, speeches, and fireworks. It’s a moving experience to be part of the crowd as the national anthem echoes through the historic square. While businesses and schools close for the holiday, the public spaces become even more vibrant, making it an ideal time for visitors to mingle with locals and soak up the festive atmosphere.
If you’re in Ho Chi Minh City or other major cities, expect concerts, cultural performances, and night markets celebrating the day with a lively flair. The atmosphere is electric, making Independence Day a particularly picturesque time to visit Vietnam.
Mid-Autumn Festival (Tet Trung Thu): Lanterns, Legends, and Mooncakes
Later in the month, usually falling in mid to late September, is the charming Mid-Autumn Festival. Known locally as Tet Trung Thu, the Mid-Autumn Festival occurs on the 15th day of the 8th lunar month. This beloved festival is steeped in legend and family traditions, with roots tracing back thousands of years. For travellers, it’s one of the most magical times to be in Vietnam, especially if you’re travelling with children or enjoying cultural festivities.
The most iconic feature of Tet Trung Thu is the display of lantern-lit streets, especially in cities like Hoi An. Streets and homes glow with colourful paper lanterns shaped like animals, stars, and boats. Children parade through neighbourhoods, carrying these lanterns and singing traditional songs, while lion dance performances energise the crowds.
During the Mid-Autumn Festival, children participate in parades with lit lanterns.
No Mid-Autumn celebration is complete without mooncakes—rich, round pastries filled with lotus seed, red bean, or egg yolk. During the Mid-Autumn Festival, families will buy mooncakes and pomelos to celebrate. These delicacies are exchanged among family and friends as a symbol of unity and good fortune. In local markets and bakeries, you’ll find a wide variety of mooncakes in ornate boxes, perfect as souvenirs or to enjoy on a balmy evening.

Aside from lanterns and mooncakes, the festival is a time to celebrate the harvest and the moon’s symbolism of harmony. In villages and smaller towns, you may even be invited to local gatherings or folk games. For travellers, the Mid-Autumn Festival offers a rare chance to see Vietnamese culture in its most joyful and nostalgic form.

Best Places to Visit
Vietnam in September offers a diverse palette of landscapes and experiences shaped by regional weather variations and seasonal charm. From misty mountains in the north to golden rice terraces and sun-drenched coastal towns, this is a wonderful time to explore the country beyond the typical tourist trail. Here are some of the most promising destinations to consider this month.
Hanoi: Culture, History, and Comfortable Weather
September is one of the most pleasant times to visit Hanoi. The intense summer heat softens into cooler temperatures, and with fewer crowds, the city takes on a calm, almost romantic feel. Tree-lined boulevards glow under the golden early-autumn light, and the gentle scent of milk flowers fills the air—a local sign that autumn has arrived.

Ha Long Bay & Lan Ha Bay: Tranquil Waters and Fewer Tourists
Just a few hours from Hanoi, Ha Long Bay and its quieter neighbour, Lan Ha Bay, are stunning year-round, but visiting in September comes with added perks. The skies often clear after brief showers, offering dramatic views of limestone karsts rising from emerald waters. And with fewer tourists, you can enjoy a more serene boat tour through these UNESCO-listed waters.

However, do keep an eye on the weather forecast, especially in the early part of the month when stormy weather can occasionally disrupt sailing. That said, late September tends to offer improved conditions and calmer seas—ideal for kayaking, cave exploration, and sunbathing on the deck.
Mu Cang Chai: Golden Terraces and Ethnic Culture
For a truly authentic and jaw-dropping experience, make your way to Mu Cang Chai in northern Vietnam. As September marks the peak of the harvest season, the landscape transforms into a sea of terraced rice fields in radiant hues of golden colour.

This mountainous district is home to several ethnic groups, including the Hmong people, whose vibrant culture adds depth to the already captivating scenery. While a bit remote, the effort to reach this northern town is richly rewarded—especially for photographers, hikers, and travellers seeking a less-commercialised Vietnamese experience. It’s also a fantastic destination for those looking to enjoy outdoor activities in the fresh, alpine air.
Da Nang and Hoi An: Lanterns and Historic Beauty
In Central Vietnam, Da Nang and Hoi An offer a perfect blend of beach and culture. While these cities do receive a fair amount of rain in September, it’s also the off-peak season, which means fewer tourists and more peaceful sightseeing.
Hoi An, in particular, comes alive during the Mid-Autumn Festival. When the lantern-lit streets of the Old Town create a magical setting for evening walks. Local bakeries brim with mooncakes and traditional performances line the riverbanks.

Even with occasional showers, this area provides plenty of opportunities for discovery.
The Mekong Delta: Floating Markets and Tropical Abundance
In southern Vietnam, the Mekong Delta begins to emerge from the heaviest rains, and rainfall decreases noticeably as the month moves along. The lush river systems buzz with life, and travellers can explore bustling floating markets, sample fresh tropical fruits, and enjoy boat tours through sleepy canals.

Travel Tips
Planning a trip to Vietnam in September is exciting, but a bit of prep can make your experience even smoother. This is a month of changing skies and vibrant culture, so flexibility and awareness are key. Whether you’re navigating bustling cities or venturing into quiet rice terraces, here are some essential travel tips—blended with wisdom from our Local Designers—to help you get the most out of your journey.
1. Pack for Rainy Seasons
September straddles both the rainy season and the onset of autumn, so your wardrobe should be as versatile as your itinerary. Rain gear—like a lightweight waterproof jacket, travel umbrella, and water-resistant shoes—is essential, especially if you’re spending time in southern Vietnam or the central regions.
Local Designer tip: Don’t forget quick-drying clothes and a compact day bag for spontaneous outdoor adventures.
2. Monitor the Weather Forecast, But Stay Flexible
Vietnam’s weather conditions in September can vary widely from region to region. While stormy weather might be forecast in Ha Long Bay, it could be sunny and clear in Da Lat or Mui Ne. Checking the weather forecast regularly helps you plan day trips or adjust routes accordingly.
3. Embrace the Festivals—Even the Crowds
The Mid-Autumn Festival and Vietnam National Independence Day are among the country’s most cherished holidays. While popular tourist sites may get busy, the cultural immersion is worth it. Join locals as they celebrate in lantern-lit streets, try mooncakes, and enjoy free performances and street parades.
4. Book Transport and Accommodation Early for Independence Day
September is one of the cheapest months to travel in Vietnam. And if your travel dates include September 2nd, be sure to secure your transport and hotel bookings in advance, especially in Hanoi and Ho Chi Minh City. Domestic travel surges during the holiday as locals visit family or attend parades.
5. Choose Regional Itineraries Wisely
Given the mix of wet and pleasant weather, consider focusing your itinerary on regions that align with your interests and weather preferences.
Local Designer tip:
- Head to the North if you’re after amazingly magnificent scenery and autumn hikes.
- Stick to the central highlands for cooler temperatures and outdoor exploration.
- Explore the Mekong Delta for its cultural charm and floating markets, especially as rainfall decreases.
6. Don’t Skip the Local Cuisine
September is a great month to enjoy local cuisine—especially warming noodle soups, fresh seafood, and seasonal fruits. In southern Vietnam, you’ll find an abundance of fresh tropical fruits like rambutan and dragon fruit lining roadside stalls.
Local Designer tip: September was the best time for trying street food—fewer tourists meant shorter queues, and locals were happy to chat and recommend their favourite dishes.
