Key highlights and things to do in January
January is a good month for temple visits, market browsing, and short excursions from the city because of the cooler, drier weather. Popular city activities include exploring Old Quarter streets on foot, photographing pagodas such as Tran Quoc Pagoda on West Lake, and sampling warming local dishes in street stalls and small eateries.
Outside the city core, several day trips remain attractive in January. Duong Lam Ancient Village, located roughly 50 km northwest of central Hanoi and reachable in about 1 hour 30 minutes by road, offers old architecture, communal halls and narrow lanes that appeal to history and photography interests. For island or bay itineraries, many travellers connect from Hanoi to coastal destinations; for practical guidance on public transport options to islands near Ha Long, see how to reach Cat Ba Island.

Practical tips for traveling in January
Layered clothing is the most useful packing strategy for January: thin shirts for daytime, plus a sweater and a light jacket for mornings and evenings when temperatures fall. Mornings often feel damp, so a compact umbrella can be handy even though heavy rain is uncommon.
Expect heavier local traffic and busy markets in the run-up to the Lunar New Year (Tết). Motorbikes are often the fastest way to move through congested streets, and many travellers prefer booking rides by app during peak periods. For morning food options and where to try classic local dishes, consult our guide to Hanoi breakfasts.
- Pack layers and a light water-resistant jacket
- Buy market items early in the day to avoid crowds
- Use motorbike taxis during business-hour congestion
- Carry a mask if you have respiratory sensitivity during hazy mornings
Cultural context and January festivals
January often overlaps with the lead-up to Tết, Vietnam’s most significant holiday according to the lunar calendar. Streets and shops display flowers and festive goods; traditional foods such as bánh chưng and mứt Tết (candied fruits) become prominent in markets and family gatherings. Note that some businesses may close around the official holiday dates, while many public celebrations and temple visits increase in frequency.
Several traditional events also take place in the weeks after the lunar new year. Le Hoi Go Dong Da is observed on the fifth day of the first lunar month and includes parades and historical reenactments at Dong Da Park. Le Hoi Co Loa runs from the sixth to the eighteenth day of the lunar month to honor the ancient Co Loa Citadel, featuring processions and folk activities. Hoi Lang Khe Thuong is a village celebration held between the third and seventh days of the lunar new year, showcasing community rituals and folk games.
- Tet (Lunar New Year): family gatherings, temple visits, market activity
- Le Hoi Go Dong Da: parades and martial arts displays on the 5th lunar day

Who January suits — and how it compares to other times
January is well suited to travelers who prefer cooler weather for walking, photography and cultural observation rather than hot, humid conditions. It is also attractive to those interested in experiencing Tet-related markets and rituals, provided they are prepared for potential closures and larger crowds near the holiday.
If your priority is beach weather or warm swimming temperatures, January is less ideal for southern coastal regions’ water activities; however, for city-based exploration and cultural events, January ranks highly. For planning multiple stops in Vietnam that consider seasonal differences, consult regional weather guides and travel logistics for optimal timing.
