How should you plan around the seasons?

For the February to April window, plan the Old Quarter and Temple of Literature in Hanoi, then a Ha Long Bay cruise, and Da Nang with Ba Na Hills and Hoi An. Book early for April, when crowds are moderate to high. In the summer months, start sightseeing early, rest in the afternoon and keep evenings for walks by the river or the beach. In October and November, prefer indoor visits and keep a flexible spare day for weather.

Who suits which season?

Travellers who handle heat well may enjoy May to September for beaches and river walks, provided they plan outdoor sights for early morning. Families with children may prefer February to April, when the weather is milder and the outdoor walks are easier. Travellers who want quieter sights may choose October or November, when crowds are lower, but should accept more rain and changing cruise timings.
