Visiting Hoi An is on the vast majority of tourist itineraries when travelling through Vietnam. It’s a unique, charming, cultural destination that will always be recommended from traveller to traveller—but when is the best time to go? And Hoi An weather is really great to spending for any weekend if you single or have any family. Due to the sheer length and topographic Geography of Vietnam, wet and dry seasons develop independently and are therefore quite different between the southern, central, and northern parts of the country. This can make planning a trip somewhat challenging if you’re trying to gauge climates along a travel route.

That’s where we come in! In this article, Hidden outlines the Hoi An weather and climate throughout the year, along with a month-to-month breakdown to help plan your trip and manage your expectations. Be it a quick stopover or an extended stay, nobody wants to have travel plans hindered too much by the weather.

Hoi An Weather And Climate:

Hoi An is positioned along the centre of Vietnam’s lengthy coastline and is governed by two main seasons—wet and dry. The two seasons are self-evident and don’t leave much of a shoulder season for residents—it’s one or the other. The only variable is when they tend to start and end, and this period only shifts by a month or so.

The total length of the dry season typically stretches from February to September, but within this timeframe, it has its fluctuations. February to April has the most moderate temperatures averaging a high of 30°C (86°F) making it a popular choice for tourists to visit the ancient city of Hoi An.

Moving on from May, the temperatures continue to rise and hit a peak in June, where it then plateaus until September when the seasons change. Last but not least if you’re looking for sunlight, the highest number of sun-hours are found from May to July.

During the months of October to January, the wet season brings increased rainfall and the temperatures down to around an average high of 25°C (77°F). The months of October and November contain the bulk of the rain, and it’s not unusual that during this time the Old Town and the islands south of it have the possibility of flooding. While it doesn’t often happen, when it does the waterfront businesses have no choice but to close down. However, as quickly as the water levels return to normal, so do the businesses.

Flooding

Although flooding doesn’t happen every year, it is something to be aware of when planning your trip during the rainy season. Flood levels vary, mostly it’s restricted to the Old Town and immediate surrounding areas, some years it experiences knee-high water, while others it has received multiple metres. It’s best to check the weather forecast ahead of time if you expect to travel to Hoi An from October to December. Here are a related article about An Bang Beach. You should to see that.

If flooding does occur during your time in Hoi An, know that the locals are super adaptable and prepared—the weather won’t bring your travels to a full-stop. Many riverside businesses in the old town stack up their chairs and move their valuables upstairs to get ready for the flooding.

Interestingly, you may even notice that some shops have flood levels from previous years marked on their walls. Depending on the severity, only a portion of the city is affected by the flood, and even so, the shops and specially restaurants are usually back in business within a day or so.

Furthermore, it’s an incredibly unique experience to be in Hoi An during this time. Imagine locals paddling their boats through the picturesque laneways of Old Town! Flooding can happen, but life in Hoi An carries on.

If planning a trip to Hoi An, come prepared for both warm summer days and some wind and rain to be here, or at least be on the way. Flooding also has the chance of occurring, which effects all riverside businesses in the Old Town. However, once the water levels recede, the businesses recover right away and are open for visitors.

Best Time To Visit Hoi An:

Taking into account all the information and statistics, including tourism levels, precipitation, and national holidays, Hidden suggests these two periods to visit Hoi An: March/April and September.

March and April

March and April have the benefit of falling into an abyss of stability, climate- and activities-wise. Tet has passed so you won’t find yourself surrounded by shut businesses and also the tour operators and classes will be functioning regularly.

Tourism levels at this time are above average but are still nowhere near the peak in July and August.

The temperatures are still mild compared to the annual peak, which is good for those who are coming from cooler temperatures. Rainfall during this time is also at its lowest point out of the year, making this a great time to plan for outdoor activities in the surrounding area.

September

The hottest months have passed, and the temperatures are slowly but finally moving down towards a more tolerable range. Another welcomed reduction is found in the form of tourists, as the flocks of people that were visiting the city in August have moved on as well. This helps in bringing prices back to a more moderate point for travellers.

September also brings the chance to witness The Mid Autumn Festival at the end of the month. Even if you’re here before this time, you can still see sessions of young people practising in the evenings for the upcoming event
