In the north, such as Hanoi and Ha Long Bay, the period between October and December is ideal because the weather is cool, dry, and clear, perfect for sightseeing and outdoor activities.
For central Vietnam, including Hoi An, Da Nang, and Hue, February to May is the best time, with lots of sunshine and minimal rain, making beach trips and cultural tours very enjoyable.

The south, like Ho Chi Minh City and the Mekong Delta, experiences its dry season from December to April, which is the best time to explore the bustling cities and lush countryside without heavy rains.
