Weather – Relocating to Hoi An


Some will tell you that the weather in Hoi An is always warm or hot, having only a wet and a dry season, typical of tropical climates. Don’t believe them. At certain times of the year, Hoi An can be very chilly indeed.

What is the best time to be in Hoi An?
Most agree February to May is best – after the wet and cold and before the big, enervating heat of high summer. During these months the days are sunny and warm and free from the debilitating heat and humidity that comes in July – August.

How hot does it get in summer?
The summer months are June – August/September. The days are dry and very hot with temperatures regularly in the mid to high 30s with overnight minimum temperatures uncomfortably high. Although it’s the dry season, the humidity remains quite high.

When is the rainy season in Hoi An?
The rainy season is from September – January. However, it is not uncommon to have dry, sunny and sometimes very hot days on and off throughout this period.

Is it true that Hoi An has typhoons?
Yes, but they manifest more as heavy rains and very strong winds which can result in flooding. From time to time, there are typhoons that are more dangerous but these are infrequent. Typically, torrential rain, flooding and typhoons occur October and November.

I didn’t think Vietnam got cold.
Yes, this is a perception shared by many but let us assure you, Hoi An can get very cold during December and January. The temperatures may not appear that low on a chart but when combined with the wet season and high humidity this combination can cut through you like a knife. However, such days are minimal and mostly the temperature is moderate and sometimes hot enough to swim.

When is the best season for diving?
Water clarity is at its best April to August but divers would probably prefer diving during the hot, summer months of June – August for optimum conditions.

Can I swim all year round?
You can swim all year round in Hoi An but, with so many hot months, most locals stay out of the water during ‘winter’.

What are the best months for surfing?
For surfers the ‘winter’ months produce the only reliable swell.
