So when is the best time to visit 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.


Hoi An flooding: when is the rainy season in Hoi An?

The rainy season is from September – January but October and November have the heaviest rainfall by far. However, it is not uncommon to have dry, sunny and sometimes very hot days from time to time throughout this period.


Are there typhoons in Hoi An?

Yes, but Hoi An weather is more typified by heavy rains – rain depressions – 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 not frequent and mostly the temperature is moderate and sometimes hot enough to swim.


Hoi An diving: 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.

I’ve been told not to visit Hoi An during Tet, is this true?

Yes. Tet is the Vietnamese equivalent of Chinese New Year. It occurs in late January or early February and is the most important celebration in Vietnamese culture. Tet is a time when most Vietnamese return to their ancestral home and the streets are overwhelmed with spring flowers.


Travel is at a premium so flights, trains and coaches are booked out, many establishments and shops put their prices up so you may be paying a Tet price for your hotel or newly tailored suit. To cap it off, most restaurants and businesses shut down for close to a week. In short, avoid travelling at this time if possible.


But if you want to see Vietnam in festive spirit Tet can be a great time to come if you plan ahead well enough and are prepared to pay a little more. Marking the onset of Spring, Hoi An weather at Tet is typically warm and comfortable.


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’.


As a surfer, when is the best time to come?

For surfers the ‘winter’ months produce the only reliable swell. It’s important to note that Hoi An is not a prominent surfing destination, however, visitors can enjoy a wide variety of water sports including wind surfing and diving – the latter being particularly popular.
