Hoi An Weather
The dry season
February to May is the prime window. Skies are mostly clear, humidity is bearable and the sea calms from April. March and April are the comfortable months before the heat peaks, ideal for walking the old town and combining sightseeing with beach time.
The hot months
June to September brings high heat and humidity with bright, swimmable seas. Plan activities for the morning and evening, rest through the midday heat, and lean on indoor experiences like a cooking class in the hottest part of the day.
The wet season
October and November are the wettest, with heavy bursts and possible flooding in the low-lying old town, easing into a cooler, drier January. It is quieter and cheaper but needs flexible plans and indoor backups. Pack a light rain jacket.
