Southern Vietnam climate
Before discussing the specific weather in March, it’s important to understand the overall climate in southern Vietnam. The region experiences a tropical monsoon climate, which divides the year into two main seasons:
- Dry season (November – April): This is the sunniest time of the year, with minimal rain and more stable temperatures.
- Rainy season (May – October): Characterized by higher humidity and frequent afternoon downpours.
Travel Tip: Compared to the north, which starts warming up in March, and central Vietnam, where the dry season has just begun, southern Vietnam follows a more stable pattern with warm temperatures year-round. While central Vietnam’s beach weather improves from April onward, the south’s climate remains consistently warm.

Events and holidays in March
March in southern Vietnam is a relatively calm month in terms of large-scale festivals, but it still offers unique cultural and historical events. The biggest nationwide holiday this month is Hung Kings’ Commemoration Day, while coastal communities in the Mekong Delta and Phu Quoc may hold Whale Worshiping Festivals to honor the sea. This is also a great month for travelers looking for fewer crowds and good weather.
Whale Worshiping Festival (Cau Ngu Festival) (Dates vary, often in March – April)
The Whale Worshiping Festival is an important tradition for coastal fishing communities in southern Vietnam, particularly in Vung Tau, Phu Quoc, and Mekong Delta provinces like Ben Tre and Soc Trang. Fishermen believe that whales (Ca Ong) are sacred creatures that protect them at sea. During the festival, fishermen organize colorful processions, dragon dances, and ritual offerings to pray for safe voyages and a good fishing season.
For travelers: If you’re visiting Phu Quoc or Vung Tau, check if a Cau Ngu Festival is happening nearby. The event is most vibrant in fishing villages, where you can witness parades and rituals. It’s a great way to experience Vietnamese maritime culture, but as this is a local event, it’s not heavily publicized, so asking locals or guides is the best way to find out where to go.
Hung Kings’ Commemoration Day (if it falls in March)
Hung Kings’ Commemoration Day honors Vietnam’s legendary Hung Kings, the founders of the first Vietnamese state. The official holiday is on the 10th day of the third lunar month, meaning it usually falls in March or April. While the main ceremonies take place in the north, people across southern Vietnam still visit temples and offer incense to the Hung Kings.
For travelers: While this holiday isn’t as disruptive as Tet, some government offices and businesses may close for the day. If you’re in Ho Chi Minh City, you can visit Hung Kings Temple in District 9 to see locals paying their respects. However, this isn’t a major tourist spectacle like Tet or Mid-Autumn Festival.
