December is the winter in the North of Vietnam, rainy and cold season in the Central Coast, the dry season in the Central Highlands and South of Vietnam.
The cold Northeasterly Monsoon is often strong in the North at this time of the year; the monsoon causes long-lasting rains and cold weather in the Central Coast, rough sea from the North to Ca Mau. It is normally dry in the North in December; though not often, there may be rains each time there is a new spell of the Northeasterly Monsoon. The humidity in the North is normally low between 40-60%. There may be snow or frost in the far-northern mountains of Vietnam.
In the Central Region, December is the rainy season with more often daily torrential and incessant rains. It is really cold here during this month and especially when it rains. There may still be typhoons in the Central Region which may cause floods and landslides and halt of road and rail traffic; but the strong and cold Northeasterly Monsoon often helps to push tropical depressions/typhoons southwards that the chances that they influence the inland are small.
December is the start of the dry season in the Central Highlands and South of Vietnam. It may rain in the Central Highlands if there is a tropical depression but more likely it is dry all over the region as well as in South Vietnam. The temperatures are lovely at this time of the year in these two regions: mild sunshine and pleasant temperatures.
