Typical for the tropical climate of Vietnam, Hoi An city possesses warm weather the whole year with its average temperature of 29 Degree Celsius. The city only has two main seasons: rainy and dry seasons instead of four seasons like in Northern Vietnam.
The heat reaches its peak on the months from June to August when the highest temperature measured during day time is 38 Degree Celsius while the lowest temperature only drops at 21C Degree at night. Winter-like weather falling in the town from November to January bring coldest days to Hoi An when daily average temperature is between 19 to 24 Degree Celsius. However, this coldness seems to be of no concern for tourists from Northern Hemisphere.
The most annoying factor in Hoi An should be its rainy season, lasting quite long from September to January. Its constantly heavy shower, which may also occur with typhoon and cause floods sometimes, can accidentally disturb your wonderful trip. During the damp season Hoi An sees a sharp decrease in the number of visitors.
On the other hand, Hoi An’s dry season from February to May is the best time to visit the town, since its weather becomes very mild and beautiful with moderate temperature, low humidity, less rain and warm sunshine. For ones who enjoy sunbathing on famous beaches near Hoi An like Cua Dai Beach or An Bang Beach, delaying your trip to the end of May or beginning of June is recommended.
If you are lucky enough to arrive at the town on the 14th day of a lunar month, Hoi An will be much more charming with its Full Moon Festival and “Old Street Night” exclusively available on that day.
