What January weather in Hoi An looks like
January marks a transition from the heavy rains of the autumn months toward the drier period of spring. Average daytime readings generally sit in the low 20s Celsius, while evenings can feel noticeably cooler, so many visitors bring a lightweight layer for after-dark walks.
Rainfall in January is moderate compared with October–November: recorded monthly totals usually fall in the 90–100 mm range and are typically spread across around 7–10 days. Most showers reported are brief rather than prolonged downpours, so weather interruptions are often short-lived.

- Typical night temperature: ~17–18°C

Key features and highlights of January climate
Humidity remains noticeable in January — commonly around 85% — but cooler air temperatures make the moisture feel less oppressive than in summer months. Morning mist or light fog over rice paddies and the Thu Bon River is reported occasionally, creating calm, photogenic scenes.
The UV index on clear days is usually moderate (around 6–7), so while sun protection is sensible for daytime outings, the intensity is lower than peak-summer levels. Air quality is often improved compared with busier tourist seasons, helped by reduced traffic in the ancient town.
- Humidity: roughly 85% (typically manageable in cooler weather)
- UV index: commonly 6–7 on sunny days

Practical tips for visiting in January
Pack adaptable clothing: short-sleeve shirts or light layers for daytime, plus a sweater or thin jacket for evenings and breezy river rides. A compact umbrella or light raincoat is useful since showers are possible but not usually long-lasting.
Because January coincides with preparations for the Lunar New Year (Tet), some vendors and services may change their hours closer to the holiday. If your trip overlaps with Tet dates, most find that booking accommodation and transport earlier reduces stress and potential price hikes.
- Clothing: layers and a light jacket for evenings
- Rain gear: compact umbrella or raincoat recommended
- Reservations: consider booking ahead if travelling near Tet
- Mobility: cycling is comfortable in cooler temperatures
Cultural context and seasonal events
January is a time when locals begin gearing up for Lunar New Year, so markets sell flowers, decorations and specialty foods. Visitors report that the town feels lively with seasonal crafts and displays, offering a window into everyday preparations ahead of Tet.
If you want to learn about regional festive cuisine, resources on ceremonial dishes explain what to expect at markets and family meals during the holiday period. Sampling local street food and visiting market stalls can be especially rewarding in January when seasonal items appear.
Tet food often becomes more visible at markets in the weeks before the Lunar New Year.
Who January in Hoi An suits best
Travellers who prefer milder temperatures and fewer crowds usually favour January. Photographers and those who enjoy relaxed exploration find the cooler mornings and lantern-lit evenings appealing.

Comparisons and alternatives
If you are comparing January in Hoi An with other regional destinations, note that coastal and island locations further south often stay warmer for swimming, while northern bays can be cooler and mistier. For an example of similar winter conditions in the north, some planning guides provide comparisons with nearby coastal areas.
Choosing between a city break, a beach stay or an active countryside visit will depend on your priorities: Hoi An in January favours cultural walks, village visits and food-focused experiences rather than beach time.
