The month of September also embraces the average temperature of about thirty degree centigrade which is similar to that of the previous months. The nights are again on the cooler side with a temperature of about twenty five degree centigrade. So, you can very well see that the summers of the Halong Bay embrace quite a similar nature of temperature and weather. The rainfall is there but it is not up to a range which cannot be bearded. So, you can do visit the bay at the summers as well and enjoy the colour and variation of nature. But again if you want to avoid the heat and humidity you can also try the other months for a pleasant vacation.

The average amount of rainfall reduces a bit for about 167mm which is lesser than the previous months and is almost equal to 7inches. The average wind speed of this place during this month is about 7km per hour which is quite moderate but in recent years a sustained wind speed was about 80 km per hour which is quite on the higher side. The sea temperature during this time is quite on the warmer side thus it is quite good news for the swimmers.
