Hanoi’s climate overview

Located in northern Vietnam, Hanoi experiences a humid subtropical climate with monsoonal influences. Unlike southern Vietnam, which remains warm year-round, Hanoi undergoes four distinct seasons, making it one of the few places in the country where temperatures fluctuate significantly between summer and winter. 

The city is heavily influenced by northeast monsoons in winter and southwest monsoons in summer, leading to dramatic changes in Hanoi temperature, humidity, and rainfall.

Hanoi weather varies significantly throughout the year, temperature in Hanoi ranging from as low as 10°C (50°F) in winter to as high as 38°C (100°F) in summer. The city experiences high humidity year-round, averaging 70-80%, which can make both summer and winter feel more intense, hotter in humid summers and colder in damp winters. Rainfall is also an important factor, with Hanoi having a distinct wet and dry season.

The wet season lasts from May to October, bringing heavy showers, occasional storms, and high humidity. In contrast, the dry season, spanning from November to April, sees cooler temperatures, lower humidity, and minimal rainfall, making it the most comfortable time for outdoor exploration. The transitional months, March to April and October to November, offer a balance of mild temperatures and pleasant weather, making them ideal for sightseeing and cultural activities.

Hanoi weather by season 

Hanoi experiences four distinct seasons, each offering a different atmosphere and travel experience. 

Spring (February - March) 

This season is one of the most pleasant times to visit, with temperatures ranging from 18°C to 25°C (64°F – 77°F). Humidity begins to rise, but it remains comfortable compared to summer. Occasional light drizzles contribute to the lush greenery, and this is also the season when Hanoi’s famous peach blossoms and red silk cotton flowers bloom, creating stunning scenery around the city.

This is an excellent time for outdoor activities, visiting Hoan Kiem Lake, the Old Quarter, or West Lake, and experiencing Vietnamese New Year (Tet Festival) if your trip aligns with the lunar calendar.

Summer (April - July)

Summer in Hanoi is characterized by scorching heat and high humidity. During this period, Hanoi temperature frequently exceeding 35°C (95°F) and peaking around 38°C (100°F). The humidity levels of 80-90% make it feel even hotter, and sudden afternoon thunderstorms are common. Despite the intense weather, summer is a great time for day trips to Halong Bay or Ba Vi National Park, where the sea breeze or highland air offers a welcome escape. If visiting Hanoi during summer, light, breathable clothing and staying hydrated are essential.

Autumn (August - October)

Hanoi’s autumn offers cooler temperatures (20°C – 28°C or 68°F – 82°F), lower humidity, and clear blue skies. The city is particularly charming during this time, with golden milkwood pine and dracontomelon leaves falling along Phan Dinh Phung Street, creating a romantic, poetic atmosphere.

This is the perfect season to stroll around Hoan Kiem Lake, enjoy egg coffee at a street café, or take a motorbike ride through Hanoi’s tree-lined streets. Autumn is also famous for green rice (cốm), a seasonal delicacy you must try.

Winter (November - December)

Winter in Hanoi is unique compared to southern Vietnam, with temperatures dropping to 10°C – 15°C (50°F – 59°F), and occasionally as low as 6°C (43°F) on the coldest days. The air is often damp, and foggy mornings create a mystical atmosphere over Hoan Kiem Lake and the city’s many pagodas.

Unlike other cold regions, Hanoi’s winter comes with high humidity, which can make it feel colder than the actual temperature. This is the season for hot dishes like pho, grilled pork with vermicelli (bun cha), and sticky rice with mung bean (xoi xeo). If visiting in winter, be sure to pack warm layers, especially for night outings.

Best time to visit Hanoi based on weather

Hanoi is a year-round destination, but choosing the right time to visit can enhance your experience. Autumn (August - September) and spring (February - March) are the most recommended seasons due to their pleasant weather and vibrant atmosphere.

If you prefer cool and comfortable weather, autumn is the perfect time. The temperature ranges from 20°C to 28°C (68°F – 82°F), humidity is low, and the skies are clear. Walking through the Old Quarter under golden dracontomelon trees or enjoying a cup of egg coffee by Hoan Kiem Lake makes autumn a magical time in Hanoi.

For those who love festivals and nature, spring is another great choice. With mild temperatures of 18°C to 25°C (64°F – 77°F) and blooming flowers everywhere, the city feels fresh and lively. This season is also rich in cultural experiences, with many traditional festivals taking place after the Lunar New Year.

Winter, from November to December, offers a different charm. Though temperatures can drop below 10°C (50°F), the chilly weather makes Hanoi’s street food even more appealing. Warm bowls of pho, grilled corn, and traditional hot tea become local favorites, and if you visit around Tet (Vietnamese New Year), you’ll witness the city’s most festive atmosphere.

Summer, from April to July, is the least favorable season due to its high temperatures (25°C – 38°C / 77°F – 100°F) and frequent rains. However, it’s the best time for day trips to Halong Bay or Ninh Binh, where you can enjoy cooling breezes and stunning landscapes.
