Vietnam weather

There is not really a right or wrong time to visit Vietnam as during most months of the year you will experience both sunshine and rain in varying quantities. Welcome to a country with 2000 + miles of coastline and three different weather systems.

Whilst Vietnam is typically warm and humid, the weather can vary significantly from one region to another due to the countries length. At times there has been snow (yes white snow!) in the mountainous far north whilst the beaches in the south enjoyed 32 °C and sunshine. It pays to imagine the country as three separate destinations when researching weather for your intended visit and the following information will hopefully help you unravel the complexities.

North Vietnam Hanoi, Halong Bay, Cuc Phuong, Mai Chau & Ninh Binh

Hanoi and North Vietnam has a distinct winter and summer season. The cool but mostly dry winter lasts from November to April when temperatures average 17-22°C with the coldest months being January – March. Summer lasts from May to October when it is hot and humid and the region experiences its highest rainfall. July to September are often the wettest months of the year. During these months severe weather can prevent junks sailing in Halong Bay although such weather is rare.

South Vietnam Ho Chi Minh City, The Mekong Delta, Dalat & Phu Quoc

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 with higher humidity. The wet season lasts from May to early November with the months from June to 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 beaches of Phu Quoc enjoy a monsoon climate with two seasons; wet (late-July to late October) and dry (November to July). Visits to Phu Quoc can be made year-round although the best time is during the dry season (outside of October the chances of sunny days remain high). Dalat is wet from June to October making outdoor pursuits problematic. From November to May it is far dryer although cold in December & January.

Mountainous Far North Sapa, Ha Giang, Bac Ha

The climate in Sapa and Vietnam’s far north-west 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 in December and January, especially at night.

The best months to travel in the north-east (Ha Giang) 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 the northwest are from September to 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 wintertime can be rather chilly, and the summer rather wet.

Central Vietnam Hoi An, Danang, Hue, Quy Nhon & Nha Trang

Hoi An, Hue & Danang in the 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.

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. At the far south of Central Vietnam, 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.
