Vietnam and Thailand Weather Overview 

Firstly, let’s take a quick look at the overview of Vietnam and Thailand's weather to find out their difference so that you can more wisely choose the best time to visit.

Vietnam Weather 

Featuring a humid subtropical climate, Vietnam's weather can vary significantly from one region to another with distinctive monsoon seasons. Generally, the dry season in Viet Nam, which sets between November and April in the North & South, March, and August in the Central, is affected by the cold, dry northeast monsoon. The rainy season, which sets in between May and October in the North and South, September, and February in the Central, is affected by the hot, humid southwest monsoon. With a coastline of more than 3,000 km, Vietnam experiences great climatical variation over the 15 degrees of latitude. Consequently, not the whole country receives moderate sunshine all year round. At the same time of the year, you can soak up the sun on the southern beaches and get frozen in the northern mountains.

In terms of topography and latitude, Vietnam is divided into three distinct weather patterns: the North, the Central, and the South.

North features the most diverse climate pattern that is defined by 4 distinct seasons: spring, summer, autumn, winter. Along with this, there are significant changes in each season. While the temperatures in the summer can reach 38°C, the winter averages may dip down to 8°C occasionally and even below zero in mountainous regions. Throughout the year, July is the hottest month with an average temperature of 30°C. And January, the coldest month, has an average temperature of 12°C. 

Central is quite similar to the North with the extremely hot months in the middle of the year. It is also the rainy season when floods frequently occur and produce negative impacts on either transportation or tourism. The Central is divided into three smaller climate zones. Overall, Central weather has dry and rainy seasons, and the biggest likelihood to experience storms, which is quite different from other regions of the country.

South offers a typical monsoon climate with year-round high temperatures and constant sunshine. The southern temperatures vary constantly around 25°C – 35°C throughout the year. In particular, there are two distinct seasons: the dry and the wet.

Thailand Weather 

Thailand can best be described as tropical and humid for the bulk of the country during most of the year. Besides two typical seasons of the tropical climatical region (hot season from March to mid-May and dry cool season from November to February), the country experiences a rainy season from mid-May to October. This can be quite almost like Vietnam because the country also experiences the time of year. The difference is that the season in Vietnam varies in regions, while it only occurs in one period of time in Thailand.

However, that does not mean Thailand's weather doesn’t vary according to topography and latitude. In fact, it actually does and is split into the Northern and the Southern Peninsular.

Northern features the foremost distinct three seasons. Between November - May, the weather is mostly dry. However, this is broken up into the periods of November to February and March to May. The latter of these two periods has the higher relative temperatures as although the northeast monsoon does not directly affect the northern, it does cause cooling breezes from November to February. The other northern season is from May to November and is dominated by the southwest monsoon, during which time rainfall in the north is at its heaviest.

The southern has only two distinct seasons, the wet and the dry. These seasons do not set in at the same time on both the east and west sides of the peninsula. On the west coast, the southwest monsoon brings rains and often heavy storms from April through to October, while on the east coast the most rain falls between September and December. Generally, the southern parts of Thailand get by far the most rain, with about 2,400 millimeters every year, compared with the central and northern, both of which get about 1,400 millimeters.
