That is why it is always important for travelers to check for local news reports about weather and climate before planning their trip during these season; it will certainly save them lots of trouble spent dealing with unexpected situations. In, this article, we will also talk about more about worst time to visit Halong Bay.

Why summer is not the best time to visit Halong Bay?

Summer is generally considered the worst time to visit Halong Bay. During summer months, temperatures can soar up to 35°C and humidity levels can be extremely high. Additionally, this is also the peak season for tourism in Vietnam as it coincides with school holidays, making prices of travel and accommodation high. Moreover, this is also the time when tropical storms can struck and make the cruises dangerous.

However, summer isn’t necessarily the best time to visit Halong Bay. Here are five reasons why you should avoid visiting during this time of year. 

Crowded Tourist Sites: During the summer months, Halong Bay can get quite crowded with tourists from all over the world. This means that some of the most popular attractions may be too crowded for you to enjoy them fully and without feeling cramped or rushed. This can make it difficult to take pictures or even relax on your vacation! To avoid this, try to visit during times when tourist numbers are lower like right after peak season. 

Hot Weather: The hot weather in Halong Bay during the summer months can be extremely uncomfortable and even dangerous if you’re not prepared for it. Be sure to wear plenty of sunscreen and drink lots of water while out sightseeing so that you don’t get sunburned or dehydrated. Bring along a hat and sunglasses as well, just in case! 

High Prices: Accommodation prices in Halong Bay tend to be higher during the summer months due to increased demand for rooms from tourists looking to escape their own hot cities or countries during this time of year. If budget is an issue for you, consider visiting at a different time of year when prices are lower and there’s less competition for rooms and activities. 

Unstable Weather Conditions: Summertime also brings with it unstable weather conditions such as thunderstorms, strong winds, and even typhoons in some parts of Vietnam. These unfavorable conditions can make it difficult or even impossible to explore Halong Bay on your own terms which can ruin a much-anticipated trip. It’s best to check out forecasts before heading out so that you know what kind of weather conditions you might face during your stay in Halong Bay. 

Poor Air Quality: The air quality in Vietnam isn’t great at any time of year but it tends to get worse during the summer months due to increased heat, humidity, and pollution from cars and factories nearby. If poor air quality is an issue for you, consider wearing a face mask when exploring outdoors. Additionally, try to avoid spending too much time outdoors if possible.

Precautions while visiting Halong Bay in summer months

As with any tourist destination, there are certain precautions that should be taken while visiting this popular site during the summer months. Let’s take a look at some important safety tips that all travelers should keep in mind when planning their trip. 

Check The Weather Forecast Before You Go: It goes without saying that you should always check the weather before you embark on your travels. When visiting Halong Bay during the summer months, it is especially important to be aware of potential storms and heavy winds since they can affect the waters around Halon Bay and make it more dangerous for boating activities. Try to plan your trip around days with good weather forecasts so that you can enjoy your time in Halong Bay safely.  

Bring Sun Protection and Reapply Regularly: The sun in Halong Bay can be intense during the summer months so it’s important to bring proper sun protection. This includes sunscreen, sunglasses, hats, and protective clothing. Be sure to reapply sunscreen every few hours or so if you’ll be out in the sun for a long period of time. Also remember to stay hydrated—bring plenty of water or other beverages with you and take regular breaks when necessary. 

Be Cautious While Boating: Halong Bay offers many opportunities for visitors to explore by boat but it’s important to always exercise caution while boating here. Make sure everyone on board has life jackets and check that they fit properly before setting off on your boat journey. Avoid swimming in areas near boats or where there are strong currents since these can easily become hazardous conditions if not managed carefully. And if possible, try to avoid boating during times when storms or high winds are predicted since these conditions can create dangerous waves on the open water.  

Be Aware Of Your Surroundings: When exploring Halong Bay, try to remain aware of your surroundings at all times especially when walking through caves or exploring less-traveled spots on land. Remember that many parts of this area have hidden rocks or slippery surfaces which could cause serious harm if not navigated properly. Make sure everyone traveling with you is wearing sturdy shoes with good grip as well as other protective wear like hats and sunglasses (if necessary).


All things considered, visiting Halong Bay is an enjoyable experience regardless of the time of year.

However, the best time to experience this magical place seems to be sometime between October and April, when sunny days with mild temperatures are ideal for sightseeing as well as taking advantage of the many activities available in and around the bay.

On the contrary, summer and early fall can be detrimental to your trip due to rainy weather, humidity, and overcrowding; all strong disincentives for making a trip that might not end up being what you expected.
