When is the best time to visit Vietnam?
Weather in Vietnam, because of its elongated topography, possesses a complex
pattern, leading to a variety of conditions potentially prevailing across the
country at any given time. Whilst this fact may lead to encountering significant
climactic variances during a countrywide tour, it also means that there is no
‘bad time’ for visiting Vietnam. Wet periods are typified by heavy downpours,
which can last for up to a few hours, but will seldom last a whole day, and are
therefore not necessarily obstacles to enjoyable travel during these periods.
NORTHERN VIETNAM
The dry season runs from October to April and is characterised by three phases.
During October and November the weather is pleasantly warm and dry. Unlike the
tropical south, the north of Vietnam experiences a distinct winter from
December to February, is prone to overcast skies and spells of drizzle (known locally
as Mua Bui ‘rain dust’), and can have a distinctly chilly edge (14-20º C),
particularly after nightfall during which temperatures can fall as low as 6º C
in colder spells.
From March into May the weather becomes brighter and increasingly hot leading
up to the arrival of the wet season, the hottest time of the year, which runs
from May to September, with temperatures reaching between 25-32º C in June, and
rainfall at its highest in August.
The northwest mountains are cool all year round with January and February being
cold and prone to mountain fog and even, though rarely, flurries of snow. The
best weather for visiting Sapa is during the periods from March to early May
and September to January, when the weather is very pleasant. Heavy rainfall during
the months of June, July and August leaves the area prone to flooding and
landslides and travel to this area is not recommended.
CENTRAL VIETNAM
The area around Hue, as with northern Vietnam, has cool winters and is the
wettest area of Vietnam with the wet season extending from May through to
December, peaking in October. The area is also prone to frequent showers during
the dry season. Temperatures range from 17-23º C in December/January to 25-30º
C during June to August.
By contrast, the rest of the central coast of Vietnam, home to most of its
beach resorts, is the driest region of the country and in general, is very
fine, with temperatures around the Danang/ Hoi An area ranging from 19-24º C in
January 25-34º C in August, after which the wet season begins, running from
September through to December, with rainfall peaking in October. Further south
in Nha Trang has a similar climate. Phan Thiet (Mui Ne), Vietnam’s driest
destination, typically sports average temperatures of 20-29º C in January to 24-31º C in June, with
its wet season much less pronounced than Nha Trang and Danang.
Inland from the coast at Dalat and the central highlands, the altitude ensures
a predictable drop in general temperature levels, with a notable variance in
comfort between night and daytime temperatures which range from 13-23º C during
December to 17-26º C in May, though higher temperatures occur randomly in some
years. The area has a long wet season, running from April through to November,
with rainfall peaking during August, September and October.
SOUTHERN VIETNAM
Southern Vietnam has a tropical climate, and therefore much less marked
variance in temperature occurs, which throughout the year range from 21-25º C
at night to a daytime 30-35º C. The dry season runs from November to May and
the wet season from June to October, peaking in September. Characteristically,
however, the sharp heavy downpours take place in the afternoon, usually lasting
only a couple of hours.
