How is the Weather in Halong Bay in April?

April comes sandwiched between the moderate temperatures of March, which are just escaping the winter chill, and the start of the summer heat in May. Along with an average of eight hours of sunlight a day, which is the highest amount in Halong Bay through the year. All of this makes a decidedly good time to visit Halong Bay, with great opportunities to enjoy the beach, discover the islands, or take in the outdoor activities.


April has a few extra degrees on March, with average temperatures of 23 degrees Celsius. This is an ideal temperature for many, and a good time to enjoy the bay before May, where temperatures climb up to an average of 28 degrees. While highs in April have the ability to reach 28 degrees, the lows only make their way down to 21, making the normal temperature very comfortable and enjoyable.

That number is still fairly dry compared to the summer, where highs can reach 265mm over an average of 16 days. Like March, however, April can experience those long drizzles, where a small amount of rain stretches for long periods, unlike the sudden but brief showers in the summer months.
