1. Influence of location on the climate

Vietnam has a complex terrain. The S-shape country is typical for 3.260 kilometers of coastal line, not including islands, while three-quarters of the area is mountains and plateaus. For each of Vietnam destinations and each season, you will have different exciting experiences. In other words, it is hard to say certainly the best time when to travel to Vietnam.  Although it completely belongs to the tropical area, the Vietnam climate is divided into three separated areas of climate.

• Northern Vietnam and North Central Vietnam have a humid subtropical climate. There are four seasons in a year: Spring, Summer, Autumn, Winter.
• Central Vietnam and South Central Coast are typical for the tropical monsoon climate.
• Southern Vietnam is known for grasslands with an average temperature of 18°C and a severe dry season. The average rainfall in the driest month is under 60 mm.

1.1. Northern Vietnam

The climate of this area is unstable and have significant changes in every season:

• North Eastern includes Northern Delta and the gently sloping area alongside the Red River. These mountains, in shape of green bows, absorb northeast monsoon and northern cold wind in winter. It also stays next to the east side of the Gulf of Tonkin and covered by the highest mountain in Indochina, Hoang Lien Son, in the west. Therefore, it is directly affected by tropical storms (between June and September) but less affected by the dry and hot wind. 

• Northwest includes mountain ranges from the right bank of Red River to the Hoang Lien Son range. The later stretches in west-north to east-south direction, which plays an important role as a huge wall to reduce the coldness of the Northeast. The temperature of the Northwestern area is higher than the Northeast 2 to 4°C, not including the effect of the height.

1.2. Central Vietnam and South Central Coast

The climate of Central Vietnam and South Central Coast is typical with the tropical monsoon. The dry and humid seasons of the area does not coincide with the two others. In summer, with a considerable amount of rainfall around the country, it is in the driest season. The temperature is completely different in two sides of the Cloud Pass (Hai Van Pass):

• The north side of Hai Van pass: The winter is shorter than the North and the summer is really hot due to the Foehn effect. In winter, Thue Thien Hue Province and the surrounding areas are especially affected by the northeast monsoon passing the sea and bringing along with vapor, then creating severe rains. In summer, the southwest monsoon makes it rain on the western hillside but continues to blow toward the other side, creating a dry climate up to 40°C while the moisture is about 50%.

• The south side of Hai Van Pass: It has another name South Central Coast, which is not affected much by the Foehn effect. The climate is a bit warmer and a little cold in winter. 

1.3. Southern Vietnam

It includes Bình Thuan Province, Tay Nguyen, and South Delta. It is known for the tropical monsoon climate and subequatorial climate with abundant sunlight. The area has two main seasons: the dry one (from May to November) and the rainy one (from December to April). During the year, the temperature is much stable than other reasons in Vietnam.
