The best time to visit Hoi An is between January and May, the most comfortable stretch of the year on these averages.
Hoi An is a warm-year climate with a drier stretch and a wetter one, not four seasons in the European sense. The hot months are the outdoor months until the rain takes over. Hoi An is a city in Vietnam. This page is about Hoi An, not a country average.
Most visitors come in the drier stretch and treat the wet months as a different trip: slower days, heavier skies, still warm. The monthly table on this page still owns the averages. This layer is how Hoi An actually feels.
