When Is the Best Time to Visit Halong Bay?

Published on January 28, 2014

We're often asked "When is the best time to go to Halong Bay?", and the answer is sometimes complex. It depends on your preference: are you looking for the best time to get the best deal or the best time to travel when the weather is at its best? One person's best time can be another's worst!

Halong Bay

Best Time to Visit in Terms of Weather

If weather is your major concern, then the best time for a Halong Bay tour is in spring and autumn, to be more specific, in March, April, September and October. In these months, the weather is often delightful, the temperature is mild, the sky is clear and bright, and the activity level is high.

Best Time to Get the Best deal

If you are a budget traveler and want to get the best deal, the period from May to September can be the best time. The period is often considered as the low season of Halong Bay. Many cruise ships offer great discounts. The prices can be 10 - 20% lower than that of the high season (from October to April). However, the risk of bad weather goes up in summer due to frequent shower and unpredictable typhoon. In those cases, you can visit the other parts of northern Vietnam first and visit the Halong Bay later as the bad weather won’t last long. Smart travelers will look for last-minute vacation deals while keeping an eye on the weather forecast at the same time. 

When to Visit Halong Bay

While there is the best time to visit Halong Bay, chances are that not all of you have the option of time. Let me say this to calm you: for Halong Bay, any time can be a good time for travel. Each month or season in Halong Bay has its own advantage or disadvantage. Here is a rough guide to the weather condition of each month in Halong Bay, read through and decide on when to visit Halong Bay.


best months to visit Halong Bay

January - February

The climate tends to be cold and foggy with low visibility. And Halong Bay sees the most colorful festivals taking place in Vietnam, including Tet Festival. 

Overall: average time to visit, cold weather, abundant festivals

March - April 

During the two months Halong Bay enjoys pleasant weather, clear and blue sky. Some days have light rain. Domestic tourist volume is low.

Overall: best time to visit, delightful weather, fewer domestic travelers, not many events and festivals.

May 

May is early summer in the north of Vietnam. Temperature rises. Some days have light rain. The low season of Hlaong Bay begins, meaning you may get a great deal on cruise. But avoid visiting during the Liberation Day (on April 30) and Labour Day (on May 1). 

Overall: good time to visit, fine weather, good deal 

June - August

Weather can be sunny and clear during this time, but extremely hot. There is high chance of showers and unpredictable typhoon. In general, August is the hottest time of the year as well as the wettest. From June to early September, Vietnam sees a high volume of domestic tourists (summer vacation of Vietnam); tourist spots are crammed with people, especially beaches. 

Overall: ordinary time to visit, hot weather with short storms and typhoons, crowded beach. 

Tips: If you travel to Halong Bay in these summer months you will need to bring sunglasses, sun cream, insect repellent, swim-suit and changes, one baseball hat or wide-brimmed sun hat, flip-flops/waterproof sandals, and a light sweatshirt/sweater for chilly mornings and evenings. Please be aware that, summer is the most active period of jellyfish, which can doesn’t cause too much trouble but popular symptoms such as hives, and rashes. Ask your guide or captain for advice before going to swim.

September - October

The weather is the most beautiful in the year for Halong Bay. Temperature is moderate, so you can avoid the notorious heat of summer. The sky is clear, and the wind is gentle. Domestic tourist season is over.

Overall: the best time to visit, great weather, fewer domestic travelers

November - December 

The weather is cold, dry and cloudy. But it’s still possible to see some lovely sunny, cloudless days. If you come to Halong Bay in this period, you’re suggested to bring warm clothing and a waterproof jacket in case of rain. Alternatively you can purchase them in Vietnam at low price.

Overall: ordinary time to visit, cold weather.
