Overview of Hanoi’s Winter Climate
Winter in Hanoi brings in cooler air, less daylight, and lower rainfall than you’ll see the rest of the year. You can expect mild temperatures, moderate humidity, and a light, steady drizzle that shapes daily life here.
Typical Winter Temperatures
Hanoi gets chillier in winter than most of Vietnam. Highs usually reach about 18–20°C (64–68°F), while nighttime lows can dip to 14–16°C (57–61°F). January tends to be the coldest month.
You won’t see snow or freezing temps, but the damp air and cloudy skies sometimes make it feel colder than the numbers suggest. Unlike Hanoi’s hot summers, the days are short and sunlight is weak, so the air stays cool almost all day.
Snow just doesn’t happen here—Hanoi’s subtropical climate keeps it out of the question. Still, foggy mornings pop up often, especially near lakes or rivers. These fogs can cut visibility and add a chilly bite, especially early on.
Humidity and Its Effects
Humidity in Hanoi doesn’t go away in winter. It usually sits around 70% to 80%, which is less than in summer but still pretty noticeable. The air feels damp, especially when it’s cool and cloudy.
This dampness makes the cold feel sharper. A simple jacket often isn’t enough, since the moisture in the air makes it harder to stay warm. Locals usually wear layers so they can adjust as the day goes on.
Fog and mist show up a lot in the mornings. The air feels fresher than in summer, but you should still expect a persistent chill that’s a far cry from dry winter climates.
Winter Rainfall Patterns
Rain in Hanoi’s winter is light compared to the monsoon months. You can usually expect 15–20 mm (0.6–0.8 in) of rain each month, spread out over a handful of days. February is typically the driest stretch.
Instead of heavy downpours, you’ll mostly get light drizzle. Streets can stay damp for ages, even if it’s not raining at the moment. Gray skies and misty air are part of the winter scene here.
Flooding isn’t an issue in winter, thanks to the limited rain. But the mix of drizzle, fog, and cool air slows things down and can affect your outdoor plans. Even on dry days, you should expect damp conditions.

Daylight shifts, too. December gives you about 11 hours of daylight, while June stretches past 13 hours. Winter sunshine averages just 4–6 hours a day, compared to 9–10 in summer.
So, winter feels calmer and better for walking, while summer is hot, sticky, and stormy—you’ll want more breaks inside.

How to Prepare for Hanoi’s Winter
Hanoi’s winter often feels colder than it looks on paper. High humidity, drizzle, and a lack of indoor heating can catch you off guard. If you prep right, you’ll stay comfortable as you explore the city’s streets, markets, and cultural spots.
Essential Clothing for Winter
Daytime temps usually run 14°C to 19°C, but at night, it can fall to 11°C or even lower. The damp air makes it feel colder, so pack more than just a thin sweater.
Bring a medium to thick coat—wool or a down jacket works well. Layering is key, since mornings and evenings are cold, but midday can be milder. Try this setup:
- Base layer: long-sleeve shirt or thermal top
- Middle layer: sweater or fleece
- Outer layer: windproof or insulated jacket
Wear comfortable closed-toe shoes, especially if you’re walking around Hoan Kiem Lake or the Old Quarter. If you get cold easily, add scarves, gloves, and a hat. Locals tend to wear thin puffer jackets and sneakers, which are perfect for both sightseeing and daily life.
Pack at least one set of water-resistant clothing. Drizzle is common, and umbrellas can be a pain in crowded areas.
Tips for Managing Dampness and Cold
Hanoi’s winter is cold and humid, with moisture hanging in the air. Rooms can feel clammy, and clothes dry slowly. Pick a hotel with heating or dehumidifiers if you can—it makes a big difference.
Carry moisturizer and lip balm, since the cold air and low humidity indoors can dry out your skin. A power bank is handy, too, because cold weather drains phone batteries faster.
Outside, drizzle is pretty common, especially from late January through March. A compact umbrella or light raincoat keeps you dry without weighing you down. Skip heavy cotton clothes—they soak up moisture and stay wet for ages.
If you’re heading outside the city or into villages, wear sturdy shoes with good grip—paths can get slippery. Warm drinks like egg coffee or ginger tea are local favorites for warming up after being outside.
Winter Activities and Experiences in Hanoi
Hanoi’s winter brings cool, dry days and misty mornings, setting a cozy mood for walking, sightseeing, and enjoying hot food. You can check out historic sites, seasonal flowers, and traditional celebrations that really show off the city’s culture this time of year.
Popular Outdoor Activities

Flower viewing is a winter highlight. Streets and gardens fill with white daisies in late autumn and yellow mustard blossoms in December. Phan Dinh Phung Street and Gia Lam’s flower fields are popular for photos and just soaking in the colors.
Historic sites feel different in winter. The Temple of Literature, Ho Chi Minh Mausoleum, and the Old Quarter are easier to explore when it’s cooler. Short drizzles happen a lot, so having a jacket or umbrella on hand makes things easier as you move around.
Seasonal Foods and Festivals
Food is huge in Hanoi’s winter. Warm up with pho, bun cha, or rib porridge from street vendors. Don’t miss egg coffee—it’s rich and unique, especially at classic spots like Café Giang.
Festivals make the season lively. Christmas brings decorations to churches and malls, and New Year’s Eve has countdowns in public squares. The big one is Tet (Lunar New Year), usually late January or February, when families prepare banh chung (sticky rice cake) and swap seasonal treats.
Markets like Dong Xuan Market and smaller flower markets get busy and colorful. Visiting them gives you a close-up look at how winter traditions mix with daily life.
Travel Considerations for Visiting Hanoi in Winter

Accommodation and Transport Advice
Hotels and guesthouses in Hanoi get pretty busy in winter, especially if you’re looking around the Old Quarter. If you book early, you’ll probably snag better rates and stay closer to all the main sights.
A lot of mid-range hotels offer heating, but some budget rooms don’t—definitely double-check before you reserve.
When it comes to getting around, walking just makes sense in the cooler weather. The Old Quarter’s streets feel tight and lively, so you can wander through markets and cafés without much hassle.
If you want to cover more ground, grab a metered taxi or use a reputable ride-hailing app. That way, you won’t get stuck overpaying.
Public buses cost very little, but they can get packed, especially during rush hour. If you’d rather have more freedom, you might rent a bicycle or motorbike, though honestly, Hanoi’s traffic can feel overwhelming, so be careful out there.
If you arrive by train or plane, taxis and shuttle services will get you into the city center. Winter evenings tend to be damp, so it’s smart to plan your transfers ahead and avoid waiting outside in the cold.
