Last updated on
October 1, 2019

October of Halong

Halong Bay is very hot from April to September but cools from October to March.  

It is difficult to define what the best month is to visit this natural wonder because this totally depends on the preference of each visitor.

For example, many avoid rainy months for fear of frequent downpours and tour cancellation due to bad weather but others love the quiet atmosphere of this low season.

No matter what season you prefer, October is no doubt one of the best months for visitors thanks to its amicable weather which is, overall, neither too hot or too cold.

Here are 5 things you need to know when planning a Halong Bay tour in October:

1. The weather is very pleasant

Generally, September is still very hot but rather wet (though not as blazingly hot as summer months) while November brings along chilly winds and crowds of visitors.

October stays in the middle as you can still feel the warmth of summer but without lots of daily downpours.

The average temperature during October is 25 C degree with the highest of around 28 C degree and the lowest of 21 C degree at night.

As a result, this cool weather is ideal for those who feel uncomfortable with the summer’s heat in Vietnam. Since this month is not really prone to heavy rains, the risk of tour cancellation is low compared to the previous 3 months.

Near the end of the month, there can be some chilly days but you still do not need to pack heavy sweaters with you; just light summer clothing and a light jacket will be enough. In case you spend a lot of time outside, bring some sunscreen with you.

There are about 6 hours of nice sunshine each day and the average humidity level is 72%, which are quite the same as in September. It rains about 11 days this month but also does not each long each time.

2. The sea water is perfect for swimming

If you love swimming, October is a great time to do so with the average sea temperature of about 27 C degree. It is totally fine to swim for hours without worrying that it is too hot outside.

From November, it starts to get cold for swimming.

Swimming in the calm, emerald green water will be a very refreshing experience for you so do not miss it. Let your body flow on the water, feel the smooth-white sand and watch the golden sunshine above to chase away your worries of daily life.

With moderate temperature and light, cool breezes, visitors can take part in various outdoor activities without worrying about sweating too much.

Now that the chances of frequent downpour ease remarkably, visitors can freely explore each and every corner of islands, caves, and grottoes in Halong Bay.  

Try riding around the island on a rented bike to see the daily life of local people and watch over the island from different angles along the way.

For adventurous visitors, activities like hiking and kayaking are the right fit for you.

One small tip when it comes to kayaking: do not worry that this is for the professionals only. In fact, this activity is designed for everyone and even amateurs can quickly grasp the basics after about 30 minutes.

The amicable weather of October is ideal for booking a cruise to explore the island.

Better yet, the romantic light breeze at night will accompany you when you witness sunset and sunrise on the cruiser’s deck.

It is wonderful to watch the water turn from emerald to grey-blue and then to crimson with the last rays of the sun, signalling the night come.

At that instant, suddenly the bay becomes one color only before being coated in the moon’s silver light. Sunrise brings about hopes of a new beginning with a brand new day.

It is such an amazing experience that you should not miss!

Last updated on
April 10, 2019

Tourists often do research in advance to make sure they pick the right month to visit a foreign location. Because Halong – a site of Natural World Heritage – is one of the most well-known tourist destinations in Vietnam, it is normal when you see many tourists posting questions about the weather in this place.

One question that has not been properly answered is during which month, the weather is better to visit Halong, April or May?

Many people think that it is May because the sea temperature is better for swimming and diving. Take a look at the following article to find the information you need to make your decision.

halong bay view

1. In terms of weather

It would be a lot easier to compare the weather of two months in two different seasons. For example, you can easily tell the difference between May and October.  However, because the weather patterns in April and May are quite the same, even the slightest difference matters when you make your decision.

  • Average temperature

While April is more like a transitional month from spring to autumn, May marks the starts of the summer and brings along with its higher average temperature of around 27.5 C degree.

The highest temperature can reach 31 C degree but do not worry too much because the heat in May is largely endurable compared to other summer months.

Besides such indispensable items like shorts and flip-flops, you will need to pack some sunscreen.

  • Sunshine

The number of sunlight increases from 4 hours per day to 7-8 hours per day with lengthened daytime over a month.

Do not forget your camera at home or miss opportunities to photograph the splendid rock formations or blue sky of Halong Bay during this month of the year.

  • Rainfall

With infrequent rain, April is considered a dry month of the year in Halong while it is slightly likely to experience summer storms in May.

There are about 14 days of rain in May with an average rainfall of 192mm. The average humidity level is 75%.

  • Sea temperature

The average sea temperature in May is 27 C degree, about 3 C degree higher than in April, make it more suitable for swimming and diving activities.

Bring your swimsuit and enjoy a peaceful time in the emerald green water. Some recommended swimming locations in Halong are Ti Top Beach and Tuan Chau Beach.

2. In terms of tourist turnout

Compared to April, you will be more likely to get better deals because many travel agencies run special summer promotions from the beginning of May. It is the start of the low season in Halong.

The biggest event in May is the Halong Carnival Festival – depending on each year, this event can be held by the end of April and early of May.

You can learn a lot about Vietnamese culture and take part in various exciting activities to promote tourism during this festival.

The International Labor Day on May 1st is another rare holiday for local tourists.  Other than that, May is a great month for you to explore Ha Long without worrying about tourism.

3. Recommended activities

The weather in April and May are all suitable for water-based activities and adventures so there is essentially no difference here.

You can take part in popular activities like hiking, canoeing, visiting caves, swimming, and squid fishing. Take note that May is warmer so you may sweat more but the sea temperature makes diving a better choice.

To witness the wonderful underwater world of Halong, you will need useful equipment like snorkel, mask, exposure suit, etc. You can either bring your own stuff or rent on the spot.

Cruising is always a good choice; it is up to you to choose among various cruise packages. A package of 3 days and 2 nights normally includes extra activities like squid fishing, visiting floating villages, and bike riding.

With not so many differences between April and May, which one do you prefer? If you do not mind the summer heat, both of these months are suitable for your visit.

In case you love to take part in the carnival festival, choose the month in which this event is held. In general, October is probably the best month in terms of weather but April and May rank close behind it.

Considering all the factors like weather, tourist turnout, events, prices, these months may even offer better travel experience than other months in the peak season.

With authentic festivals, clear sky and no risk of the typhoon, extreme weather, or hike in prices during April or May, why do you still hesitate?

Top 4 reasons to visit Halong Bay in April

Last updated on
April 6, 2019

When considering the suitable time to book a tour to Halong Bay, which is considered the jewel in the crown of the Vietnam tourism industry thanks to its magnificent landscape, which factors do you consider?

For the most comfortable weather, autumn months are most likely your choice.

One of them is April, which is often overlooked as it is the transitional month of spring to summer and is an off-peak month. However, Halong Bay weather in April is very ideal for outdoor activities and sightseeing.

Let’s take a look at several reasons why you should also consider visiting Halong in April:

1. The weather is comfortable

If you wish to avoid the extreme heat of summer, the chilling cold of winter or high risks of typhoons during the autumn months, April is one of the best options.

In April, the weather is neither too cold nor hot as the winter is already over and summer is only on its way. The average temperature is around 23 C degree with the highest temperature of 28 C degree and the lowest temperature of 20 C degree.

Visitors can expect about 4 hours of sunlight per day and lengthened daylight time during this month of the year. The sky is so clear and blue that it is very easy to take great pictures.

Compared to March, the humidity level and average rainfall increase to 75% and 79mm, respectively; however the weather is still quite comfortable, especially for outdoor activities.  

The sea temperature gets warmer at 24 C degree so it is fine for swimming. There are probably some infrequent strong winds but overall that that does not lead to tour cancellation and April is still considered a great time to visit this charming beauty.

2. It is not the peak season

When you visit Halong, it is best to avoid the weeks where the following events take place: Hung Kings Temple Festival (a traditional festival held annually from the 8th to the 11th day of the third month – according to the lunar calendar) and Reunification Day (held annually on April 30th).


On such days, the number of local tourists may increase to take advantage of official holidays. Of course, that may lead to crowds and a price increase for certain services.

Other than these dates, it is highly possible that you can enjoy quality time during your solo trip because local people are busy with working and exam preparation.

Generally speaking, April is not the peak travel season in Halong Bay.

[elementor-template id="4134"]

3. There are many great outdoor activities to experience

  • Squid fishing

For those who like fishing and may want to try their luck in catching some fresh squids, April is a suitable time for this activity.

If you are only able to get small squids, do not be surprised before April only marks the start of early squid fishing season.

The best time to catch big squids normally falls on winter months but it is always fun to try fishing and enjoy your freshly caught squids no matter how big or small they are, right?

  • Water-based activities

Besides swimming, it is highly suggested that you experience cruising, canoeing and kayaking activities in Halong during April.

Such activities offer great opportunities to enjoy the beauty of Halong in an up-close manner. There are signature destinations you should surely visit like Sung Sot and Titov Caves.  

A shortstop for about 1-2 hour at floating villages will help you understand a very important part of Halong’s rich culture.

Take note that if you love diving, it is best to book a trip to Halong during May-November. The weather during these months is more idea for diving activities than in April.

  • Hiking and mountain climbing adventures

Without sweating too much in the heat, you can take on an outdoor adventure on the mountains of Halong Bay to enjoy the breathtaking view from the top.

There are many sport climbing routes for you to choose from.

Also, if you are interested in nature conservation, the Cat Ba National Park near Ha Long Bay is also recommended for your stay in Vietnam.  

  • Sightseeing from the seaplane

It is such a divine experience to enjoy the panorama of Halong Bay from a seaplane.

The clear blue sky of Halong during April provides a wonderful backdrop for you to see each and every corner of the place.

This deluxe service will cost you quite a sum but it is definitely worth every penny, especially for photo hunters.

What are you still waiting for? Let’s pack your bag and say goodbye to spring with a trip to Halong during this month of the year – you will not regret the amazing experience in this place.
