Weather Overview for Ha Long Bay

Ha Long Bay has a tropical climate with two distinctive seasons. The summer is wet and hot while the winter is dry and cool. The average temperature in the region ranges between 15 and 25 degrees Celsius, but can plummet significantly in the winter. There are times of heavy fog with low visibility, and violent tropical storms during the summer months. The annual recorded rainfall is between 2000 and 2200 mm.

Ha Long Bay is in north-eastern Vietnam. UNESCO designated the area as a World Heritage Site. Its coastline extends for 120 km from the Yen Hung district to the Van Don region. The popular resort area Luang Prabang in Laos is located to the northwest of Vietnam. To the north is the Chinese resort area of Shanghai.
