March and April are great months to visit Halong Bay; the weather is not too hot, not too cold and although there are higher chances of rain and increased humidity, it’s easily one of the most beautiful times of year to visit Halong Bay.
The pleasant weather, coupled with longer days, means there is more opportunity for outdoor activities. Better still, due to the lack of tourists in this period, there’s more space for you to take in the stunning majesty of the Halong Bay.
Halong Bay is an explosion of beauty and charm in spring, where orchids bloom and nature flourishes. The air is fresh and sweet, the scenery is breath-taking, and the temperature is perfect. The weather itself creates an ominous yet alluring mist that sweeps through the bay and fills the ancient cave systems, creating a spectacular display at dawn and dusk.
More daylight hours
One of the major appeals for anyone hoping to get off the sun lounger and into the bay itself is the joy of spring’s increased daylight hours. This gives you more time to get out in the water before watching the sun set over the limestone karsts. March and April receive the most daylight hours of any month in Vietnam, with eight hours of sunlight a day, so don’t miss out.
Not too hot
While Halong Bay’s tourism may peak in fall, it tends to drop in the summer, when the weather is at its hottest and stickiest. In spring, however, the climate is optimal, with temperatures ranging from 19 to 24 degrees Celsius and a lot less humidity, though there are high chances of a light, but consistent, drizzle.
Not too crowded
With Vietnam’s tourism peaking in fall, a holiday in Halong Bay around spring provides a less crowded atmosphere, making ventures off the boat and into the water all the more immersive. On a clear day, you can feel as though you have this ancient seascape all to yourself.
Due to the lack of tourism, prices are often lower than other times of the year, making some options more affordable.
Landing in April each year, Halong Carnival is the biggest festival in Halong, with a colorful, vibrant atmosphere, thousands of actors, dancers, singers, musicians and students, most of whom are Halong residents.
Optimal time for activities
Warming up after the winter chill, spring offers a comfortable temperature, not too hot, nor too cold. This creates the perfect climate for Halong’s many outdoor activities, including rock climbing, biking, kayaking or hiking, all of which you can enjoy even if there’s a sprinkling of rain.
