Best Time to Visit Hoi An
Recommended: Feb to Jul
When to go
February to July is driest and least crowded outside Tet. August-September brings heat and humidity but manageable rain. October through January is the wet season, with typhoon risk peaking Sept-Nov; the Ancient Town has flooded multiple recent years, sometimes closing streets for days. December-January is cooler and rainy but has fewer tourists.
