Southern Vietnam climate
Before diving into the weather details for October, it’s useful to understand the general climate of southern Vietnam. The region has a tropical monsoon climate, meaning warm temperatures throughout the year and two distinct seasons:
- Dry season (November – April): Marked by stable weather, little rainfall, and warm temperatures.
- Rainy season (May – October): Characterized by high humidity and frequent rain showers, often in the afternoon.
Travel Tip: Southern Vietnam’s climate follows a different pattern than the north and central regions. While northern Vietnam starts cooling down, and central Vietnam is in the middle of its rainy season, the south remains warm with occasional heavy showers.
Weather in South Vietnam in October
October is toward the end of the rainy season, bringing high humidity, frequent showers, and warm temperatures. Daytime highs range from 28–32°C (82–90°F), while nighttime temperatures stay between 24–27°C (75–81°F). The heat remains consistent, but the humidity makes it feel even warmer.
Rainfall is still significant, averaging 200–350 mm (8–14 inches). Humidity levels remain high, around 85–90%, contributing to a heavy and sticky atmosphere.
Rain showers are common, often occurring in the afternoon or evening. While heavy downpours happen frequently, they are usually short-lived rather than lasting all day. The transition to the dry season begins late in the month, leading to slightly less rainfall compared to September.
Beach conditions in South Vietnam in October
While South Vietnam’s cities and countryside are rich in history and culture, its beach destinations like Phu Quoc, Con Dao, and Mui Ne are a favorite for travelers seeking a mix of relaxation and adventure.
October is not a good month for beach activities in Phu Quoc and Con Dao, as the rainy season is still in full effect. Heavy rain, rough seas, and strong waves make swimming unsafe on many days, and boat trips to nearby islands can be disrupted. Mui Ne experiences less rain than the islands, but humidity is high, and short showers occur frequently.
Travel Tip: For better beach conditions in October, head to central Vietnam, where Da Nang, Hoi An, and Nha Trang still experience warm beach weather at the beginning of the month before the rainy season starts there as well.
Is October a good time to visit South Vietnam?
October is a good month to visit South Vietnam, as the rainy season starts to ease. Rain showers are still common, but they become less intense toward the end of the month. The Mekong Delta is still lively, with high water levels making for great boat trips. Ho Chi Minh City becomes more comfortable to explore, with slightly cooler temperatures. While not ideal for the beach, October marks the transition to drier conditions, making it a decent time to visit if you’re okay with some lingering rain.

Events and holidays in October
October in southern Vietnam is a great time to experience ethnic cultural celebrations, especially with the Kate Festival of the Cham people and Ooc Om Boc Festival of the Khmer community (if it falls this month). While there are no major national holidays, these regional festivals offer unique insights into Vietnam’s diverse ethnic traditions. The weather is also shifting, with the rainy season tapering off, making it a good time for travel.
Kate Festival (Cham People’s New Year) (Lunar September 1; usually October)
The Kate Festival is the Cham people’s most important celebration, marking their New Year and honoring ancestors. It is widely celebrated in Ninh Thuan Province, where many Cham communities live, but also in Cham villages in southern Vietnam. The festival includes processions to temples and towers, traditional Cham music and dances, and vibrant ceremonies honoring Cham kings and deities.
For travelers: The best place to experience Kate Festival is in Ninh Thuan, particularly at the Po Klong Garai and Po Rome Cham towers, where grand ceremonies take place. If you’re in southern Vietnam, some Cham villages in Binh Thuan Province (near Mui Ne) or An Giang Province may also have smaller celebrations. This is a unique cultural event that offers a rare glimpse into the ancient Cham traditions that still survive today.
Ooc Om Boc Festival (Lunar October 15; usually October or November)
The Ooc Om Boc Festival is a Khmer moon-worshiping and water festival, celebrated in Khmer communities in Soc Trang, Bac Lieu, Tra Vinh, and An Giang. It involves prayers for good harvests, boat races, and sky lantern releases. The highlight of the festival is the Ngo Boat Race in Soc Trang, where long wooden boats with up to 40 rowers compete in high-energy races.
For travelers: If you want to witness this spectacular boat racing event, head to Soc Trang, where thousands of spectators gather along the riverbanks to cheer for their teams. This is one of the most exciting and visually stunning festivals in the Mekong Delta, combining cultural traditions, sports, and spiritual ceremonies. If you’re not in Soc Trang, other Khmer-majority areas may also hold smaller celebrations with sky lantern releases and temple rituals.
