How are the monsoon seasons in Vietnam?

Vietnam locates in the intrinsic region of the Northern Hemisphere, so the influence of wind in the Northern Hemisphere operates year-round.

On the other hand, Vietnam climate has a strong effect on seasonal air masses with two main monsoon seasons: the northeast winter monsoon (Nov – Apr) and the southwest (May- the end of Sep).

What are the monsoon seasons in Vietnam?

The monsoon happens in various regions of Vietnam in different seasons because the land is long.

Winter monsoon:

The winter monsoon has operation time from November to April next year, moving in the northeast direction, so it is called the northeast monsoon.

The scope of the northeast monsoon comes from North Vietnam to Bach Ma Range in Hue City. In the first half of winter, the weather is cold and dry, bringing a cold and prolonged winter in the North. The second half of the winter season is cold and humid, with drizzle rain in the coastal areas and the North and Central plains.

Moving to the south, wind weakens, less cold, and almost stopped in the Bach Ma range. Thus, from Da Nang onwards, the wind blows in the Northeast direction strongly, dominating and causing rain for the Central Coast, while South Vietnam and the Central Highlands come in dry seasons.

Summer monsoon:

The duration of the summer monsoon season is from May to October with two winds blowing in the same southwest direction.

The first half of summer (May – July): with the scope of the southwest monsoon, the tropical mass of the Bay of Bengal moving southwest and penetrates directly into Vietnam, causing heavy rains for the Southern Delta and Central Highlands.

After that, this air mass crosses the Truong Son range, causing a dry and hot effect in the coastal plains in the Central and the South of the Northwest region.

Mid and late summer (June – September): Southwest monsoon (from near-tropical high pressure in the southern hemisphere) operates. Crossing the equatorial sea becomes hot and humid, and this air causes heavy rain for the wind-receiving area in the South and the Central Highlands of Vietnam.

Due to the low pressure in the North, this atmosphere mass moves from Southeast to the North, creating lot of rain happening in the late summer in North Vietnam.

The results of the monsoon seasons in Vietnam cause:

  • Creation of climatic seasons: The North has cold winter with little rainfall and hot summer with humid and rainy. And, in the South, there are two distinct rainy and dry seasons.
  • Between the Central Highlands with rain in summer (May – Aug), and the coastal plain of Central Vietnam has rained in the autumn and winter (Sep – Nov).
