The Halong Bay weather in August sees temperatures regularly soar in excess of 30 degrees. The average recorded temperatures hover around 29 degrees, and it’s exceedingly rare for it to drop below 25 degrees overall.

The Halong Bay weather in August brings just 6 hours of bright sunshine each day, which is the lowest levels of the year. Other months of the year tend to bring closer to seven or eight hours of bright sunshine each day.

The low sunshine levels and frequent rain is a common reason that fewer tourists visit Halong Bay at this time of year.

The average air humidity in August is around 75%, but it can feel much heavier than this due to the frequent rains followed by spells of sunshine where the water is evaporating off the land.

August is by far the wettest month of the year, with an average rainfall of 265mm over 16 days. This is a huge increase from even just the month before. Due to the poor weather conditions that often hit Halong Bay in August, it’s a good idea to keep an eye on the forecast before you leave for Halong.
