I -  Monsoon season in Vietnam and its influence

The winter monsoon time in Vietnam starts from November to April, affecting areas from the Bach Ma mountains back to the north, including the North and North Central regions.

From November to February, which means in early winter, the northeast monsoon is dry and causes cold winters in the North. But around the end of winter, from February to April, the northeast monsoon causes cold and humid weather due to drizzle rain. The time of the most active winter monsoon will cause severe and damaging cold spells, affecting cultivation and husbandry activities in the northern high mountains. Also, the northeast monsoon overflows into the Gulf of Tonkin causing strong wind force up to 6-7. Especially, it sometimes can cause hail, thunderstorms ...

2 - Summer monsoon in Vietnam

The southwest monsoon is formed from the center of the Indo-Myanmar low atmospheric pressure that draws wind from the North Indian Ocean through the Bay of Bengal into Vietnam and the operating time is usually from May to October each year. Two types of winds that also direct the southwest wind blowing into Vietnam, but in the North, it is in the Southeast directions.
