Hanoi Weather in December: Temperature, Rain & Travel Tips

What is Hanoi's December Weather Like?

In December, Hanoi is cool and mostly dry, with daytime temperatures usually ranging between 15°C and 23°C (59°F–73°F). Evenings can drop to around 10°C–11°C (50°F–52°F).

For many locals, this is the time of year when Hanoi finally feels calm and comfortable after the long humid summer. With lower rainfall and milder temperatures, walking around the city becomes far more pleasant.

Hanoi Weather in December: Overview

• Typical daytime temperatures range from 15°C to 23°C, with cooler evenings.
• Rainfall remains relatively low, averaging about 30 mm for the entire month.
• Humidity stays around 70%, which can make the air feel slightly colder.
• Winter daylight is shorter, with roughly 4–5 hours of sunshine each day.

Why Does Hanoi Feel Colder Than the Temperature Suggests?

For many visitors, Hanoi can feel colder than expected in December. Even when the temperature is around 18°C, the air may feel noticeably cooler.

Locals often describe this winter sensation as “rét ẩm”, or damp cold. Because humidity remains relatively high, the chill tends to linger in the air and seep into clothing more than in dry winter climates.

Wearing several light layers usually feels warmer than relying on one heavy coat.

Air Quality and Fog in December

During winter, Hanoi occasionally experiences haze linked to a weather pattern known as temperature inversion, where cooler air traps pollution closer to the ground.

This effect is usually more noticeable in the early morning and tends to improve later in the day as sunlight and wind help disperse the haze.

• Check daily air quality using apps such as AirVisual (IQAir).
• If pollution levels are higher in the morning, outdoor walks are often more comfortable in the afternoon.

What to Do in Hanoi in December?

The cooler and drier weather makes December one of the most pleasant months to explore Hanoi on foot. Walking around the city becomes much easier compared with the hot and humid summer season.

Explore the Old Quarter

Winter temperatures make it comfortable to wander through the narrow streets of the Hanoi's Old Quarter, visit Hanoi's traditional markets, and spend time in the many cafés around Hoan Kiem Lake. The cooler air also makes casual walking and street photography more enjoyable.

Enjoy Hanoi’s Winter Street Food

Cold evenings naturally draw people toward warm dishes. Steaming bowls of pho noodle soup, grilled street food, and Hanoi’s famous egg coffee are especially comforting during the cooler months.

It is common to see locals gathering around small street stalls for hot noodle soups or grilled dishes on winter evenings. Around Christmas, Hang Ma Street fills with festive decorations, while St. Joseph’s Cathedral becomes one of the liveliest gathering spots in the Old Quarter.

Take Short Day Trips

With very little rainfall, December is also a good time for short excursions outside the city. Nearby destinations such as Bat Trang Pottery Village, Duong Lam Ancient Village, and Quang Phu Cau Incense Village can all be visited on a day trip from Hanoi.

Try Indoor Cultural Activities

On colder days or when air quality temporarily drops, visitors often choose indoor experiences such as cooking classes, coffee workshops, traditional massage treatments, or water puppet shows.

What Clothes to Wear in Hanoi in December?

Although temperatures are not extremely low, Hanoi’s humid winter can feel colder than expected. Wearing layers usually provides the most comfort.

• Light jacket or windbreaker: useful during evenings and windy days.
• Sweater or fleece: helpful during cooler mornings.
• Long pants and closed shoes: comfortable for walking around the city.

Because winter air can also dry the skin, bringing moisturizer and lip balm is recommended.
