When should you NOT visit Hanoi Vietnam?

There are a few times of the year when you might want to avoid visiting Hanoi.

Monsoon season in Hanoi

The first is during the monsoon months of June, July and August when it will be hot, humid and rainy. So it's not the best time to explore if you're looking for a fresh weather experience. July is one of the hottest months in Vietnam and Hanoi's weather features drizzle rains and severe weather - it truly is the peak season of the wet season.

With heavy rain, there is often flooding in the city and exploring the countryside can be a wash-out. This can certainly limit Hanoi day trips and weekend trips to staying indoors.

If you're planning to visit Hanoi during these months, it's best to check what the weather will be like before you go.

Tet holiday

The other time to avoid is during Tet holiday which usually lands around the beginning of February.

This is the biggest holiday of the year and many businesses, shops and tourist attractions will be closed. The city shuts down and many Vietnamese people leave Hanoi to travel to their hometown. It's not the best time to visit if you want to experience all that Hanoi has to offer.

If you're planning to visit Hanoi Vietnam during this festive season, make sure to do your research ahead of time to see what's open and what's not. Plus, think about buying your friends some amazing Tet gifts.

Hanoi is a year-round destination, with a temperate climate, and many exciting and cultural things to discover. Whether you are looking for good weather, beautiful scenery, or exciting festivals and events, Hanoi has it all!
