Best time in general to visit Halong Bay

The best time to visit Halong Bay comes from October to December (Autumn) when the temperature is mild, not much rain. Typically, the peak tourist season defaults the Christmas time in Vietnam and New Year, but the rest is alright to travel, not much crowded.

June to September (Summer) falls in the hot weather, a good time to swim and do outdoor activities, but also storm seasons. Although this time has a lot of Vietnamese tourists, four and five-star cruises can give big promotions because fewer foreign tourists travel by these boat levels.

January and February: Winter Covers With A Little Chill

The weather is good to enjoy the view of the sea and islands in the bay because the sky is clear.

Temperature is a little cold, on average it is 17 – 18 degrees celsius. With this temperature level, not many Vietnamese like to swim as it’s very cold for most of them.

The fog can come in the early morning and a little rain without prediction.

You should carry a light jacket to use in the early morning and the night.

A high number of tourists can occur in New Year on Jan and a few days after that, estimated from 1 Jan to 10 Jan of every year.

And, the Lunar New Year of the Vietnamese often comes in February. A lot of domestic travelers have holidays, almost all services and boats have a much higher price. But, many restaurants and shopping centers are closed.

March to May: Spring Contributes The Cheering Sky and Sea in Halong

Many people like March because it is a good time of the year to travel to Halong Bay for taking pictures. The reason comes from the clear and not strong sun, creating good light for beautiful photos.

The temperature runs from 20 degrees celsius in March on average, higher in April at 24 degrees, and jumps to 28 degrees in May. So, it creates hotter and hotter weather from March to May with humidity at the end of May.

With the temperature above, the outdoor activities in the sea start doing in April and May, but March is still cold to swim in.

That is good to travel with a beautiful cruise in Halong to do activities of sightseeing, climbing, relaxing, and kayaking.

The sudden high tourists come to Halong in April because the Hung King festival is one of the official holidays in Vietnam. This festival happens on the tenth of the third lunar month, meaning some days in April of the solar calendar.

June to September: Summer Comes for Water Activities

The weather becomes hotter and rainy. The average temperature in Halong is 32 degrees celsius from June down to 20 degrees on a few days in September.

With high heat and humidity, most guests having a journey in Halong bay like to go swimming, kayaking, diving.

But, it is not recommended to do hiking during these months because rain may come suddenly causing danger.

You also notice that the outdoor experience of the Halong cruises can stop any time due to the bad weather or storm coming.

When the storms come, the cruises are suspended. In this case, most cruises will refund or reschedule your journey on Halong Bay.

One-day tour of small boats can get plenty of Vietnamese tourists when this time is the summer holidays. But, the 4-5 star standard boats with on-bay-overnight services often offer very good deals to attract more guests.

October – December: Autumn Spreads All Over Halong Bay

As the autumn in Hanoi, October to December in Halong Bay has a clear and beautiful sky with dry and cool weather.

The temperature is on average 24 – 27 degrees celsius in the daytime; but, at night, it may drop down to 17 degrees in December.

A light warm coat should stay with you to avoid being cold at night to protect your health.

In general, autumn is a good time to travel to Halong City to enjoy the view. So, do not forget to climb up the Bai Tho mountain to get the bay and city view, going kayaking, climbing, riding around the bay.

The number of foreign tourists traveling to Halong Bay will be more and more crowded from October to December. The top peak season occurs since the second half of December because of Christmas.

The price of services of the cruises or hotel accommodations also gets a higher price. But, you have to book them in advance to avoid running out of services.

General tips to visit Halong Bay:

  • Prepare more clothes for swimming and cold weather during winter and autumn.
  • Travel on the bay with 2 days 1 night, or 3 days 2 nights staying overnight on the cruises, booking a beautiful cruise in Halong bay in advance is a good choice.
  • Travel from Hanoi to Halong Bay can be cheaper with shuttle buses supplied by the same cruise.
  • When you do not want to wait for a long time or go around the city when the shuttle bus picks up other guests around the city, a private car transfer is more convenient. Please tell us about this!
  • You should keep in touch with a travel agency or the cruise when you travel during the winter or storming time to know the condition of your cruise.
  • It is much better when your travel plan has an easy day or late departure after a cruise day in case your cruise reschedules itinerary.
  • Keep smiling if your cruise excursion is influenced by the bad weather because more inland activities and beautiful landscapes still waiting for you.
  • If you book the Halong cruise or tour with Vietnamdrive, please tell us to range another trip if you cannot come to Halong Bay.
