Halong Bay has been famous for ages as one of the Seven Wonders. Each year, the bay attracts thousands of tourists with its extraordinary beauties: magnificent karst islands, emerald water, and impressive caves. Coming to the bay, tourists usually expect serenity, enjoyment, plus a place to recharge their bodies by lying in the sunlight and taking part in water activities.

Therefore, many hesitate to visit Halong Bay in the rainy season as the weather may prevent them from thoroughly enjoying the trip. Is it the case? What can you actually expect from Halong Bay's rainy season? In the topic, we will give you the answer on whether to travel in the bay's monsoon or not.


Halong Bay Weather Overview

Situated in the North of Vietnam, Halong Bay is blessed with an Asian tropical climate that features four distinct seasons a year. Halong Bay weather, accordingly, changes over time.


Spring in Halong Bay possesses moderate temperature and pretty high humidity. Due to the beginning of the year, its weather is neither harshly hot nor bitterly cold but stays pleasantly cool with the temperature rising from 18 to 30ºC, quite suitable to have a vacation. However, the average humidity fluctuating between 68 and 75% can cause long-lasting heavy fog that can prevent you from sightseeing and other activities.


Typically, Halong Bay summer is the hottest season of the year. With the temperature from 26 to 38ºC and average humidity of around 78%, it is quite a good time to take part in water activities such as swimming, kayaking, snorkeling, diving, etc. Besides, at nightfall, the temperature can drop from 3 to 4ºC, making it quite pleasant and especially enjoyable when you are on a Halong Bay cruise. Nevertheless, from the end of June, there are more chances of rain and thunderstorms, which will make it hard sometimes to thoroughly enjoy the vacation.


Like spring, autumn in Halong Bay features a pretty high humidity of about 72%, but the rising temperature from 19 to 33ºC partly causes the fog to disperse. Therefore, the sky during this time is quite blue and bright with sunshine and slight wind; the weather is pleasant all day round, sometimes a bit cold. Also, in autumn, every natural scene in some way becomes more beautiful and attractive, perfect for sightseeing, outdoor activities, and other water activities.


At the end of the year, the weather grows colder and drier as Halong Bay winter comes with low temperature and humidity. In particular, the temperature in this season is about 10ºC less than in the fall; accordingly, the amount of sunshine falls to 4 hours a day, making it hard to keep your body warm without a heavy jacket.

Also, the weather is quite dry and sometimes a bit uncomfortable. Unlike others, winter makes Halong Bay return to its tranquil self as water activities are rarely held. Instead, tourists are offered sightseeing and maybe taking part in the locals' jobs of catching fish.


Halong Bay Rainy Season 

The rainy season takes place mainly during the summer months (from July to September) in Halong Bay, as the high temperature is usually the key reason for rain and other tropical phenomena such as cyclones, etc.
