The best time to visit Halong Bay depends on your definition of a perfect trip. If you are most concerned about the weather, the periods September – November and March–May are ideal for a trip to Halong Bay. The dry climate and pleasant temperature will enable you to enjoy all activities offered on board while making sightseeing as perfect as it could be.

If you are a budget-minded traveler, then schedule your trip between May and September. This is often considered the low season and many cruise ships offer massive sales on cabins: you can save as much as 40% on a cruise trip compared with other times in the year. However, the months of July – August often see sporadic hurricanes and storms, which may cause cancellation and delay of your trip. In those cases, you can switch around by visiting another destination in the North of Vietnam and visiting Halong Bay later. These storms will not last longer than 3-4 days.

If you do not have the option of time, then rest assured that you will enjoy your trip as much as when you do not in another month or day of the year. The Bay is filled with sunlight and rain usually does not last long. In the warmer season you can take advantage of swimming opportunities and in the cooler season you will enjoy Halong Bay like no one else: Imagine a steamy BBQ lunch by the caves in one of the most gorgeous natural complexes of the world – it’s all about experience.
