Dry season

Lasting from November to April, the dry season is regarded as the best time to visit South Vietnam when the sun shines almost all day, the sky is blue, the colours are brilliant, the air is clear, the heat is dry, humidity is low, and temperatures in the mornings and evenings drop to pleasantly mild (even chilly) levels. With the relatively high temperature in Southern (up to 39°C) but low level of humidity, it is highly recommended that visit the region in late December, you can experience the atmosphere of the Christmas and New Year in Ho Chi Minh City.  The Lunar New Year or Tet (falling in early February) is also a good occasion for experiencing the spirit of the city during these special days.

Travelling this time, you can enjoy a delicious bowl of Hu Tieu on a small boat in Cai Rang floating market without worrying about any sudden rain. May to August is the harvest season of the fruit gardens of the Southwest area. Imagine you are walking in the orchard, enjoy freely "home-grown plants, fresh fruits directly taken from the tree" and immerse yourself in nature. It will be an indescribable feeling.

Rainy season

I can say that any time is a good time to visit South Vietnam. When most travellers tend to book their holidays out of the South rainy season, there are some good reasons to ‘get wet’ from downpours. You may relieve yourself from the scorching heat in the country where the rain can be a sight of absolute bliss. Even though you are not a rain lover, you can still find the ‘magic’ in the most arduous situations of this season. From enjoying the best landscapes with only a few visitors to finding the lowest accommodation prices, or some great deals of tour combos, you should take at least one trip while it’s raining and consider Vietnam as your destination of choice. Take a closer look at the rainy season in southern Vietnam and fun things to do while travelling.

A lot of foreigners when newly arrived in Ho Chi Minh city wonder why so many citizens here own a kayak or sup with paddles inside their houses, they must haven’t experienced the Vietnam rainy season. According to Ho Chi Minh city’s topography, the average elevation is 19 metres (62 ft) above sea level. This close distance to the sea explains why during this season, the heavy rain can easily cause floods all over the city, and our Vietnamese people enjoy that. We go out happily for rain bathing, swimming and kayaking. This can be a once in a lifetime moment that you should never miss. You see, the rainy season is also a good time to go to Vietnam. And don’t forget to bring raincoats and an umbrella with you, that’s necessary.
