May Weather in Halong Bay

May is arguably one of the best months to visit Halong Bay, the weather is hot and sunshine is abundant creating ideal conditions for water-based outdoor activities. However, the Monsoon season is not far away and rainfall and humidity will see a jump in this month. While the weather is still a far cry from the real Monsoon season, you should still consider checking weather forecasts in the lead up to your trip to make sure your bookings have not been canceled or delayed. Weather in May is notoriously unpredictable so be prepared for the unexpected.
