The General Climate Features of Thailand and Vietnam

Thailand and Vietnam are Southeast Asian countries that share a tropical climate. As a result, they experience clear wet and dry seasons throughout the year. 

The two countries' weather is affected by monsoon winds and ocean currents, as well as distinct geographic features. 

▶ In Thailand, there are three main seasons: 
The Cool Season (November - February): This is when most travelers flock to the country. It is dry during this time, and it is cool too. There are low levels of humidity, so little downpours. The cool season is perfect for outdoor activities. 
The Hot Season (March - May):  During this time, the country becomes incredibly hot. The temperatures rise, and so does the humidity. It is particularly sticky and warm in central and southern Thailand. 
The Rainy Season (June - October): This is also called the monsoon period. It is when it is humid and there is heavy rainfall. Usually, the rain is short but intense. It can even cause flooding.

▶ In Vietnam, the climate changes from the north to the south: 
North of Vietnam: There are four seasons in Northern Vietnam. From November to February, it is winter. The weather is cold, especially in the mountainous areas, such as Sapa. It is spring from March to April, and summer is between May and August. Spring is mild, while summer is hot and humid. Finally, autumn is from September to October. It is also pleasant during this time, with little rainfall. 
Central Vietnam: There is a wet season and a dry season. The former is between September and February, and the latter is from March to August. During the wet season, there can be storms and typhoons. 
Southern Vietnam: There are also two seasons: the rainy season and the dry season, from May to October and November to April, respectively. Throughout the entire year, there are high levels of humidity. 

Now that you know the general climate features, learn the best time to visit Thailand and Vietnam: November to April.

The Best Time to Visit Thailand and Vietnam Together: From November to April

The most ideal time for tourists to visit Thailand and Vietnam is the dry season, which falls between November and April. In this period, the weather is fairly mild. It is not too humid, and there is more sunshine than rain. 

In addition, the temperatures are cool and comfortable. Visitors can freely take part in outdoor activities, like hiking, swimming, and cycling. It is easy to take many beautiful photos and to pack appropriate clothes too. 

In Thailand, from November to April, northern regions like Chiang Rai and Chiang Mai are very cool, while areas like Bangkok, Phuket, and Krabi in the center and south are a bit warmer. 

For Vietnam, cities such as Hanoi and Ho Chi Minh City are pleasantly breezy between November and April, so it is great for exploration. But it can be slightly chillier in the north.

During the dry season, there is no need to bring lots of weather accessories, like umbrellas, raincoats, hats, and sunglasses. You just need to wear lightweight and casual clothes. Exploring attractions and doing exciting things is convenient! 

However, it is the peak tourist season. So, it can be quite busy. Top destinations will be cramped and noisy. Plus, everything can be more expensive. It is important to plan in advance to find good deals and make bookings to save money, time, and effort, while traveling.

The Rainy Season for Thailand and Vietnam: From May to October

It is rainy in both Thailand and Vietnam from May to October, which is also known as the monsoon season. There are high levels of humidity during these months, and rain showers are frequent. Most of the time, the rain pours down in the afternoon. Sometimes, there are also storms. 

However, traveling during the rainy season also has its benefits. For example, it is great for trying local delicacies. It is amazing to try Thailand’s Tom Yum while it is pouring, as the warmth of the soup contrasts with the chill vibes. In Vietnam, you can eat Pho or Bun Bo. If you prefer something lighter, you can eat Banh Xeo, Cha Gio, Banh Cuon, etc.

There are also fewer tourists during the rainy season, so attractions are less crowded and noisy. You can get many better deals for tours and accommodations too. So, for budget traveling, the rainy season from May to October is ideal.

The Rainy Season is Also the Cheapest Time to Visit Thailand and Vietnam

As mentioned briefly above, the rainy season is more budget-friendly than other seasons. If you do not have a generous budget, traveling to Thailand and Vietnam from May to October is a great option. 

You can book hotel or resort rooms at lower rates because there is a lower demand. The same goes for tour operators and agencies. 

Since there are fewer tourists, vendors do not hike up prices too. You can comfortably sample the local cuisine and shop for local goods without breaking the bank. 

That being said, traveling during the rainy season can be a good idea for big-group travels, which tend to cost more than solo trips.
