Halong Bay Cruise Boats

There’s a reason why this magical seascape in the Gulf of Tonkin, northeastern Vietnam, is a UNESCO World Natural Heritage site and one of the New 7 Wonders of Nature. Virtually untouched, there are over 1,600 islets that dot the bay like jewels.

This unique and diverse karst landscape (land comprised of sandstone) is popular for an array of activities, from boating, swimming and kayaking, to exploring the Halong Bay caves. These geologically fascinating caves are the result of years of coastal erosion, and a must-see!

What it the Best Time of Year to Travel to Vietnam

The best time of the year to travel to Vietnam or the best time to go to Halong Bay is somewhat debatable, but generally considered between the months of March to May (Spring) and again between September to November (Autumn).

June to September (Summer) marks the rainy typhoon season, and the months of January to February (Winter) are host to strong winds and cooler temperatures.

With the best weather comes the biggest crowds, and a price tag to match. You can plan an incredible visit around the four seasons in Halong Bay, and find yourself saving money too.

Halong Bay Holiday Seasons

To figure out the best time to visit Halong Bay, you will need to know which season is the best time to go. Check out the Peak and Low season here:

Peak Season in Halong Bay

Mostly as a result of the holiday season in other parts of the world, October to December is regarded as peak tourist season in Halong Bay. The most popular month of the tourist season is December, with sporadic rainfall and temperatures fluctuating between 17℃ and 27℃.

The weather in Halong Bay is most ideal during the months of March to April when the lowest average temperatures sit around 18℃ and the highest at about 36℃. Average humidity during this time is at 75%, and you may experience some occasional rainfall.

Although known for the lowest temperature in Halong Bay, January is still considered part of the peak tourist season. Visitors who want to steer clear of the sweltering heat of summer can enjoy cooler conditions at 13℃ to 26℃, and humidity at just 65%.

Low Season in Halong Bay

Due to the typical Halong Bay climate of heat, hurricanes and stormy weather, the offseason falls roughly between May and September.

May hints to summer and heats up to an average low temperature of 29℃ and a high of around 40℃. Although humidity varies between 75% and 80%, there is little rain. An excellent time to visit Halong Bay, May is far less ‘touristy’ and considerably cheaper.

June is the start of the summer holiday season for locals, with temperatures ranging anywhere from 30℃ to 40℃. Similarly, in July, the humidity and temperatures soar, subsiding only for the occasional storm. This time of year is notorious for cancelled tours and cruises, due to storm warnings.

How To Get To Halong Bay

Located about 165 kilometres from Hanoi, and just 75 kilometres from Hai Phong, these cities will be your most likely point of departure when travelling to Halong Bay and can be navigated in much the same way, by:

  • Bus
  • Private car/taxi
  • Seaplane
  • Ferry (Hai Phong)

Once you are there, the bay itself can be traversed by one of the famous ‘junk boats’ or on a number of other best cruise Ha Long options here.

    Also a good idea to travel to Catba Island and from there visit the less explored part of Halong Bay. Less crowded and as beautiful as HB 🙂

      Yes, Lan Ha Bay is less crowed. However, now there are a lot of nice cruises starting from Got Pier in Hai Phong to Lan Ha Bay. So starting from Cat Ba Island is not only one option for Lan Ha Bay like the past. I hope you will come back to Vietnam and have a chance to try that. You may check Incredible Asia Journeys Site for different cruises in Lan Ha Bay and you will see it. Some good option cruises like VSpirit Premier, Escape Sails.
