Best Time to Visit Hoi An
The dry season
February to April brings warm, dry and comfortable weather, ideal for walking the old town. May to August turns hotter and more humid with strong sun, so plan beach mornings and shaded or indoor activities like a cooking class for the middle of the day.
The rains and the lanterns
From September the rains build, peaking in October and November when the Thu Bon can flood parts of the old town. December eases off. Whatever the season, try to be here for one full-moon evening, when the old town dims its electric lights for the monthly lantern festival.
