Vietnam’s climate

Vietnam has a tropical monsoon climate, but because of its geography, weather conditions vary from north to south. However, throughout the country, south to southeasterly winds blow from May until September, and northerly to northeasterly winds are dominant between October and April.

Vietnam’s single rainy season falls between May and September, at the time of the southern monsoon. The rest of the year is relatively dry. In the north of the country, cloudy days with light showers are more frequent at the time of the northeast monsoon, while the south enjoys a sunny dry spell.

Temperatures remain high throughout the year, however the north experiences a considerably cooler season due to the north monsoon bringing colder air from China. Frost and snow can occur, but only in the extreme highlands and for a very short period of a few days. The sheltered lowlands of the south are protected from any outbreaks of colder weather, and the dry season is hot and sunny.

During the rain season, the air is humid and oppressive. Coastal and higher regions are particularly sultry due to the frequent cloud, high humidity and lack of sunshine.

The best time to visit the north of the country is between September and December, when humidity is lower and before the heavy rains. The south and central region are best visited during the period of December until April while it is dry.
