The best month to visit Hanoi is from September to April  when the weather is pleasant wilth milder temperatures. Whilst the other months are getting a little hotter with average temperatures around 28-35ºC (82º-95ºF) and the rainy season in Hanoi happen at these time: heavy rains may happen sometimes in the summer, however, it is not consistent and does not affect your travel. But the fact is that you can visit Hanoi all year round because every season has its unique beauty.

  • Ninh Binh: 

Almost any time of the year is good to visit Ninh Binh.

Like in all the north Vietnam, May to October in Ninh Binh is hot, humid and with high rainfall. The region can be specially vulnerable to typhoons during September. November to April months tend to be cooler and dry.

However, the rainy season is also when the rice fields are at their best vivid green, so there’s really a reason to visit all year round!

  • Ha Long Bay:

Halong Bay is situated in the Northeastern part of the country, its weather is different in 4 seasons but it can be mainly divided into cold dry winter and hot humid summer.

Winter in Halong Bay lasts from November to March which lead to cold weather, getting colder in Jan, Feb… not ideal for swimming. The foggy days or strong monsoon are also visible this time. Despite of this season feature, this time rises as high season of Halong Bay tourism. The temperature is from 12ºC to 20ºC

Summer time lasts from May to early September, as other part of the Northern country, the Bay is sunny and hot for swimming under clear blue sky. There is light rain in some days and even unexpected typhoon that might cancel your trip. Temperature rises from 25ºC. Summer promotion rate can be found during this time.

Spring ( March, April) and Fall ( September, October) seems to be the best time to visit Halong bay, the weather is cool and you enjoy the best time of the year.

It is fine to visit Halong Bay all year around. Even though there are some unexpected cases leading to trip cancellation. Each season will bring you a different feeling that you will never forget.

  • Sapa – Mu Cang Chai – Ha Giang

The climate in Sapa and Vietnam’s north-west region including Mu Cang Chai is divided into two seasons: the dry season runs from October to late March with the wet season lasting from April to September. It can get very cold and frosty in December and January, especially at night.

The best months to travel in Sapa  is during the dry season, from October to April, although December and January can get very cold. We recommend avoiding travelling  in Ha Giang during the rainy season (May to September).

Trekking and adventure:
The best trekking conditions in Sapa and around Mu Cang Chai can be experienced between September & November, and from March to May. Daytime temperatures range from 15-28°C, and night-time temperatures from 10-18°C. Trekking and cycling are possible year round, however the winter time can be rather chilly, and the summer rather wet.

Hoi An, Danang, Hue, Dalat, Quy Nhon & Nha Trang

Centre of Vietnam have hot and dry weather from mid-January to late August, with temperatures often reaching the mid-30’s °C. During the winter months the rainfall increases with October and November achieving peak levels, occasionally in the form of typhoons, it is not recommended to visit Center of Vietnam during these months.

Hue is often cooler than Hoi An, especially early in the year. In addition, with each sitting on opposite sides of a small mountain range the weather can often differ between the two greatly on any given day.
Quy Nhon is a six hour drive south of Hoi An and shares a similar weather pattern although the dry season is slightly longer due to its proximity to the southern system.


Nha Trang, Ho Chi Minh City, The Mekong Delta, Phu Quoc & Con Dao, Phan Thiet & Mui Ne, Ho Tram & Long Hai

Although Nha Trang is at the far south of Central Vietnam, but Nha Trang benefits from a longer dry season (typically January to September), with high temperatures and little rain . The rainy season runs from October to early December with almost half the annual rainfall falling in October and November.
Dalat, in the central highlands, is wet from June to October making outdoor pursuits problematic. From November to May it is far drier although cold in December & January.

With temperatures remaining constant year round, the climate of the south is split into two simple seasons, wet and dry. The dry season begins in November and ends in April/early May with late February to May being slightly hotter and more humid. The wet season lasts from May until early November with the months from June, July & August receiving the highest rainfall of the year. Throughout much of the wet season rainfall is generally heavy but short lasting, often occurring in a mid-afternoon heavy downpour. The average temperatures in the south range between 25 – 35°C year round.
In the far south, the islands of Phu Quoc and Con Dao can be enjoyed year-round, with high chances of sunny days, although if visiting outside dry season, afternoon downpours should be expected.
