Weather in Vietnam

Vietnam has a particularly complicated climate and, like elsewhere in the world, weather patterns have been changing over recent years. The situation described below is therefore only an indication of the type of weather you can expect.

1. Northern Vietnam Climate:

Starting in the north, autumn (September to December) is undoubtedly the most pleasant season. At this time of year it's generally warm (average temps above 20°C), dry and sunny in the delta, though you'll need warm clothes up in the mountains and on the waters of Ha Long Bay. Winter (December to February) can be surprisingly bitter as cold air sweeps south from China bringing fine, persistent mists and temperatures as low as 10°C. Things begin to warm up again in March, which ushers in a period of good, spring weather before the summer heat begins in earnest in May, closely followed by the rainy season in June.

This combination makes for hot, sticky weather which takes many people by surprise. Temperatures, which can occasionally reach 40°C, average 30°C, while humidity hovers around 70-75%. The rain comes in heavy downpours, causing frequent flooding in Hanoi and the delta. By mid September, however, the rains are petering out, and from October onwards it's perfect sightseeing weather.

2. Central Coast Vietnam Climate:

The coastal region from Hanoi south to Hué lies in the typhoon belt. Around Hué, typhoons seem most prevalent in April and May, while further north the season generally lasts from July to November. However, typhoons are incredibly difficult to predict and it really is a matter of luck - or bad luck, rather - if you are caught. Flights are usually only disrupted for a matter of hours, but in recent years the main road and rail routes heading south have been cut by floods at least once during the typhoon season. The good news is that they usually get everything moving again incredibly quickly - within four or five days, depending on the severity of the damage.

The central region of Vietnam has a notoriously wet climate, particularly around Hué, where the annual average rainfall is a generous 3m. The so-called "dry" season lasts from February to May, though you'll need an umbrella even then. After this it gets wetter and hotter (av temps 30°C) until the rainy season begins in earnest in September, gradually easing off from November through January. Winter temperatures average a pleasant 20°C or above.

3. Southern Vietnam Climate:

Southern Vietnam is blessed with a more equitable - and predictable - climate. Here the dry season lasts from December to late April/May, and the rains from May through November. Most of the rain falls in brief afternoon downpours, so you can still get out and about, though flooding can be a problem in the delta. Daytime temperatures rarely fall below 20°C, occasionally reaching 40°C in the hottest months (March to May). Once the rains start, humidity climbs to an enervating 80%.

4. Central Highland of Vietnam Climate:

The central highlands follow roughly the same weather pattern as the southern delta. In the rainy season (May-November) roads are regularly washed out, but it can also be very beautiful at this time, with tumbling rivers, waterfalls and misty landscapes. You just have to build a bit more flexibility into your schedule.

6. When is the best time to travel  Vietnam?

The best time to visit Vietnam is any time. One of the principal tourist lures of the country is its equitable climate. There aren't any extremes of climate here, nor are there extremes of temperatures here. What you have are three principal seasons, hot, rainy and cold, with variations in temperature and the rainfall across the various regions of the country.

Vietnam stretches over 1,800km up the eastern coast of the Indochina peninsula and has various climates at the same time in different parts of the country.

Winter season lasts from November to April in the North with temperatures averaging 16 degree centigrade. The rest of the year is considered summertime with heavy rainfalls and occasional storms.

The rainy season lasts from May to October in the south. However, it only rarely rains the whole day. It gets dry after rainfall as quickly as it comes. The dry season is generally from November to April.

The central parts of Vietnam are affected by the South West monsoon season coming from Laos during May.

June experiences a muggy heat and sometimes produces typhoons and tropical storms.

During November and December there is sometimes long lasting rains. Despite of this fact, the months of November and December are constantly considered the peak period for incoming tourists.

January and February are still occasionally cloudy and rainy.

The best time for a long Vietnam tour from North to South would be from January till April. For those who wish beach holidays can come to enjoy warm water and sunshine in the central coast during summer time, from May to October.

7. Will it be hot and humid in most places?

Northern Vietnam - has two distinct seasons - hot and humid summers (vary from 24 to 41 oC) and cool and dry winters (vary from 16 to 23 oC).

Central Vietnam - coastal areas are more temperate than the sticky south (although they do experience high rainfall), while the Central Highlands are pleasantly cooler. The weather is also hot and reasonably dry from May to September. The monsoon winds then change bringing above average rain during late September.

Southern Vietnam - is fairly consistently hot and humid all year round. May - November, from 24 - 41 oC. Winter: December - April, 22 - 33oC

8. What is it this like to travel in monsoon season, will it cause trouble fos us?

During the monsoon season (usually between June, July and August) some heavy rain affects the North. Not so much the South of Vietnam. Typically, clouds come just suddenly with strong winds and make the sky dark. The rain pours down for just about twenty minutes then leaves the air cool and fresh with sun shinning.

You will enjoy less people traveling at this time, and might get some discounts for your Vietnam tours and services but be aware the weather forecast as you might get stuck somewhere due to the hard rain and typhoons.

Some short tours to the North and South are recommended but we need to take the weather into account. We strongly recommend spending time to Centre Vietnam for a beach holiday for the magnificent coral sand beaches and great sites like Hue, Hoi An, and My Son.
