Target late September for a better chance of improving conditions.

How September compares

7th of 12 overall in Hanoi, 8th for weather, 4th for space, 2nd for value. The emptiest month is June; the best value is August.

Plan around

Clearer autumn weather: Conditions become cooler, clearer and increasingly good for sightseeing. October and November deliver the best overall balance.

Not set on September?

Cooler, clearer conditions create excellent sightseeing weather.

Only six rainy days, lower humidity and mild temperatures make late November especially strong.

Good value continues as temperatures begin to ease.
