Climate and Average Weather in Vietnam

Vietnam is located in both a tropical and a temperate climate zone and the weather differs greatly between the north and south. Though both regions experience a monsoon period which has a strong influence on the weather. In general you will find a considerable amount of sunny days and a high rate of rainfall and humidity throughout Vietnam.

From November to April, the north is cool and dry, while May to October is rainy season. In the south, the southwest monsoon causes large amounts of rainfall from May to November, locally reaching 400 mm on average in some months (long-term averages). During extended periods of heavy showers, the Mekong can overflow its banks and cause flooding.

In contrast, the coastal area east of the Annamese mountain range is under the influence of the northeast monsoon, which brings more precipitation, particularly in the months of October and November.

The temperature in Hanoi can range from 19.6°C in January, to 33°C in Julu.

What is the best time to visit Vietnam?
Most people who visit Vietnam want to visit both the north, south and central part. If you would like to visit the whole country we suggest you go the second half of January and the month of February. The end of February, it is already getting seriously hot in the south.
