Key highlights and seasonal activities
December’s calmer weather and reduced visitor numbers make it a good time for cultural experiences that are harder to enjoy during busier months. The ancient core of the town offers architectural sightseeing, craft workshops and evening lantern displays along the Thu Bon River that many travelers plan around.
Other popular activities in December include short boat trips through the Old Town during higher water levels, hands-on lantern-making classes with local artisans, cooking lessons focused on regional dishes and visits to nearby heritage sites. The My Son Sanctuary lies about 40 kilometres from Hoi An and is a common day-trip option for those interested in archaeology and history.

- Relax on An Bang Beach for quiet seaside walks and seafood dining
Practical tips for visiting in December
Pack for variable conditions: lightweight, breathable clothing for daytime, plus a light jacket or sweater for cooler evenings near the river. Because short afternoon showers still occur, a compact umbrella or a thin waterproof layer is useful for day trips or market visits.
Sunscreen, sunglasses and a hat are advisable due to the typically high UV index even on partly cloudy days. For boat excursions or any time on the water, travelers should verify that operators provide life jackets and choose licensed, well-maintained boats when possible.
- Bring a light rain jacket and quick-dry clothing.
- Carry sun protection: SPF sunscreen, hat and sunglasses.
- Confirm safety equipment for any boat trips, and avoid unreliable operators.
- If planning beach time, check local weather and sea conditions before departing.
Cultural context and seasonal events
Hoi An’s Old Town retains many historical buildings, including Chinese assembly halls, the covered Japanese bridge and traditional wooden shop-houses. The town still observes monthly lantern evenings on the 14th day of the lunar calendar, when the streets and river are lit by hundreds of candle-lit lanterns—an atmospheric experience often recommended by visitors.
December also includes year-end celebrations: many residents and businesses mark Christmas and New Year with small public events and performances. These occasions can increase foot traffic around the riverfront and main squares for brief periods, although overall visitor numbers are generally lower than during peak holiday weeks in other parts of Vietnam.
If you want guidance on respectful behaviour while visiting cultural sites and communities, consider tips on how to visit with respect—local customs and site conservation benefit when travelers act mindfully.
Who benefits most from a December visit
December suits travelers who prefer moderate temperatures and fewer crowds for exploring museums, temples and markets on foot. Photographers and those seeking a quieter atmosphere for dining by the river often find December preferable to the busier spring and summer months.
Families and groups planning outdoor activities should be comfortable with occasional brief rain and higher humidity. Beachgoers who expect continuous sunbathing and swimming may find conditions less consistent than in the dry season, but many still enjoy An Bang Beach for calm walks and seafood meals when the weather is good.
- Good for: cultural sightseeing, craft workshops, photography and relaxed exploration.
- Less ideal for: travellers seeking guaranteed sun and uninterrupted beach swimming.
