When Is the Best Time to Visit Halong Bay?

Halong Bay, a UNESCO World Heritage Site and one of the Seven Natural Wonders of the World, is a must-see attraction for every avid traveler when visiting Vietnam. In case you are wondering about the best time to see, explore and experience this tourist hotspot, this may be the best post you’ll read today! We’ve got you covered, read on…

“When is the best time to visit Halong Bay?” This is actually a common question, and the answer is a little complicated. It all depends on your concept of a perfect trip. It depends on whether you’re after the best deal or the best time to come when the weather is at its finest.

Let’s break it down to bits. If you concerned about the weather, schedule your visit from September to November or from March to May. These periods are perfect for a memorable trip to Halong Bay. The pleasant temperature and dry weather will allow you take in all the sights and sounds while enjoying all the amenities and activities on board the ship.

If you are traveling on a budget and wish to get the best possible deal, then book your trip from May to September. This is considered the off season and most cruise companies offer huge discounts on cabin accommodation. You can save up to 50 percent on your cruise when compared to other times of the year.

Winter in Halong Bay (January to February)

The weather is normally cold and foggy with relatively low visibility. There’s ample sunlight during the day but in the morning and late in the afternoon expect some drizzle and fog. During this time you’ll see a somewhat ‘mystical’ Halong Bay because the limestone mountains are partly covered by fog. The advantage of visiting during this season is that the bay is less crowded and you’ll get to experience Tet or Lunar New Year – the most important holiday in Vietnam. Hence, you can admire both the beauty of Halong Bay and the festive mood everywhere you go.

Please bear in mind that certain activities like swimming or diving may not be permitted if the weather becomes too cold.

Halong Bay in Spring (March-April-May)

The average temperature during this period is 24°C, although there’s high chance of rain, particularly during March. Humidity is just starting to rise so the weather is generally pleasant, with clear blue skies. It’s therefore perfect for outdoor cruise activities like rock climbing, swimming, snorkeling and kayaking. The warm weather and the clear skies make Halong Bay more vivid compared to other months of the year. Spring is also Halong’s squid season, so you’ll get to spend an evening catching squid with the local fishermen.

TIP: Try to avoid the last week of April because it coincides with the national holiday of Vietnam. It’s likely that there will be lots of domestic tourists and price may slightly increase.

Summer Time in Halong Bay (June-July-August-September)

The weather can be clear and sunny, but for Westerners it can be extremely hot. If you wish to enjoy an unobstructed view of the landscape, particularly from a seaplane, this is the best season to do so. There’s also more time for water activities than in fall and winter. The temperature ranges from 29 to 32°C so you can soak in the sun as much as you like.

In general, the month of August is the hottest time of the year. Ironically though, it can also be the wettest. The showers come often but they don’t last long so you can just relax at the hotel and continue your activities the following day with a bright blue sky.

June to early September is the summer vacation in Vietnam so Halong Bay sees a high volume of domestic tourists. This also coincides with the rainy season with a higher chance of typhoons. Your trip or cruise can either be canceled or delayed, but almost all cruise companies offer refunds or they will reschedule your itinerary in such case.

Swimming in Halong Bay

TIPS: If you plan to visit Halong Bay during the summer months you’ll have to bring sunglasses, sunblock, swimwear, insect repellent, flip-flops/waterproof shoes, a cap or wide-brimmed sun hat, and a sweater for cold mornings and evenings. In addition, summer is the most active time for jellyfish, so ask your guide for advice before going for a swim.

Halong Bay in Fall (October-November-December)

This is an excellent time if you plan to visit Halong Bay because the weather is perfect for cruising. The humidity level drops significantly and the average temperature is around 13-21°C. The sky is crystal clear, the wind is gentle, and there is less rainfall. The local tourist season is also over.
