Climate and region of Hoi An
Hoi An is located in Central Vietnam, near Da Nang and Hue, and shares a similar weather pattern with these cities. The region has a tropical monsoon climate, meaning it experiences distinct dry and rainy seasons throughout the year.
- Dry season (February – August): Characterized by hot temperatures, low rainfall, and mostly sunny days. By the end of August, the weather begins shifting, leading to more frequent rain in September.
- Rainy season (September – January): Marked by high humidity, heavy rainfall, and occasional storms. October is one of the wettest months, with persistent rain and the possibility of flooding in low-lying areas.
Central Vietnam’s weather patterns differ from those in the north and south. For example, Hanoi and Ho Chi Minh City experience opposite rainy and dry seasons compared to Hoi An. While October is the middle of Hoi An’s rainy season, Hanoi’s wet season is already winding down, and southern Vietnam is entering its drier months.
Weather in Hoi An in October
October brings heavy rainfall, high humidity, and cooler temperatures compared to the previous months. While the rain can last for several hours, there are dry periods in between when exploring the town is still possible. However, flooding can occur, particularly in areas near the river.
- Average temperature: 25°C (77°F)
- Daytime highs: 27–29°C (81–84°F)
- Nighttime lows: 22–24°C (72–75°F)
- Rainfall: 400 – 600mm, with rain on 20–25 days of the month
- Humidity: 85–90%, making the air feel warm and damp
- Sunshine: 2–4 hours per day, with most sunny periods in the morning before rain increases in the afternoon
October is the peak of the rainy season, meaning extended periods of rain are common, and some days may experience continuous showers rather than short bursts. The risk of flooding is highest this month, especially in Hoi An’s old town near the Thu Bon River, where streets may experience ankle-deep water for a few hours to a few days.
While the rain does not make Hoi An unvisitable, travelers should plan for indoor activities and be prepared for wet conditions when exploring the town.
Beach holiday in Hoi An in October
October is not a good month for a beach holiday in Hoi An. The rainy season is in full swing, bringing frequent heavy showers, strong winds, and rough sea conditions that make swimming unsafe on many days. Even on dry mornings, cloud cover is common, and the chance of sudden rain or storms remains high.
Sea conditions are unpredictable, with stronger currents and higher waves, reducing visibility for snorkeling or diving. The humidity and cooler temperatures also mean it does not feel as comfortable for sunbathing as in previous months. If you are looking for a dedicated beach getaway, October is not the best time.
Is Hoi An worth visiting in October?
Despite the heavy rainfall, Hoi An is still worth visiting in October for those interested in history, culture, and food experiences. The ancient town is one of the most beautiful and well-preserved in Vietnam, and its charming atmosphere, lantern-lit streets, and cozy cafés make it a great place to explore—even in the rain.
While rain is frequent, it does not always last all day, and there are still dry periods, especially in the morning, when sightseeing is more comfortable. With an umbrella or rain poncho, visitors can still walk through the old town, visit local markets, and enjoy cooking classes or tailor shops. The fewer tourists in October also mean less crowded streets and a more relaxed atmosphere.
However, flooding is a possibility, especially near the Thu Bon River in the old town. Floods in Hoi An are usually not dangerous, but they can lead to ankle-deep water in certain streets, making it necessary to adjust plans slightly. This can actually be an interesting experience, as locals continue their daily routines by wading through the water or using small boats to get around.
While beaches and outdoor activities are limited, Hoi An’s rich culture and unique old town still make it a great place to visit, especially if you focus on indoor experiences and short sightseeing walks during dry moments. Visitors who prefer to avoid the rain altogether may want to spend fewer days in Hoi An and combine their trip with a drier destination in Vietnam.
Best things to do in Hoi An in October
October in Hoi An is part of the rainy season, meaning outdoor activities are best done in the morning, while indoor experiences offer great alternatives for rainy afternoons. While beach activities are limited, Hoi An’s historic old town, cultural workshops, and food experiences still make it a worthwhile destination.
Hoi An when it rains
With frequent showers throughout October, it’s important to plan for rainy conditions. However, rain does not mean you can’t enjoy Hoi An—there are still plenty of things to do. For detailed tips on what to do when it rains, check out this guide:
1. Walking through the old town
Hoi An’s ancient town is one of the most picturesque places in Vietnam, with lantern-lit streets, colonial architecture, and riverside views. While October brings frequent rain, the town remains beautiful even in wet conditions. Mornings tend to be drier, making them the best time to explore on foot, but even in the rain, an umbrella or poncho is enough to continue enjoying the charming streets.
2. Boat trip over the Thu Bon River
A boat ride along the Thu Bon River offers a scenic way to see Hoi An’s surrounding villages and countryside. Many boats have covered roofs, making this an activity you can still enjoy even when it rains. A popular stop along the river is Kim Bong carpentry village, where visitors can see local artisans crafting wooden sculptures and furniture.
3. Join a cooking class
A cooking class is one of the best rainy-day activities in Hoi An, allowing visitors to learn how to prepare authentic Vietnamese dishes. Some classes include market visits and bike rides to vegetable farms, but if the rain is too heavy, the focus will remain on indoor cooking. This makes it a great all-weather experience where you can learn to cook local specialties like cao lầu, white rose dumplings, and Vietnamese pancakes (bánh xèo).
4. Create some tailor-made clothing
Hoi An is famous for its tailors, offering custom-made suits, dresses, and shoes in just a few days. Since multiple fittings are required, rainy days are a great time to visit one of the many tailor shops, where you can design and order clothing while staying dry indoors. If a sudden rain shower starts, stepping into a tailor shop is a great way to pass the time while choosing fabrics and styles.
5. My Son day trip
A half-day trip to My Son Sanctuary is still possible in October, but starting early in the morning is recommended, as the chance of rain increases later in the day. The ancient Cham ruins are surrounded by lush jungle, which looks even more atmospheric in misty or rainy weather. Since the site has limited shelter, bringing a light rain jacket or umbrella is advised. More details about My Son can be found here.
Events and festivals in October
Mid-Autumn Festival – Late September or Early October
The Mid-Autumn Festival (Tết Trung Thu) is one of Vietnam’s most important cultural celebrations, focusing on family gatherings, mooncakes, and lantern displays. It takes place on the full moon of the 8th lunar month, meaning it sometimes falls in late September or early October.
In Hoi An, the festival brings a festive atmosphere, with lantern-lit streets, traditional dragon dances, and colorful parades. Families and children walk along the riverside, carrying small paper lanterns, while the smell of incense and mooncakes fills the air. While this festival is more focused on children, visitors can still enjoy the vibrant street scenes and cultural performances.
Lantern Festival
The Hoi An Lantern Festival happens every full moon, when the town turns off its electric lights, and the streets glow with the soft light of colorful lanterns. While there are no major celebrations or performances, the old town takes on a beautiful, peaceful atmosphere, especially along the Thu Bon River, where locals and tourists release floating lanterns.
