Hoi An, located in Vietnam, boasts a tropical monsoon climate characterized by warm weather throughout the year. There are no sharp temperature fluctuations typical of temperate latitudes, making the city an attractive destination to visit at any time. However, Hoi An's climate is clearly divided into two main seasons: the dry season and the wet season, each with its own characteristics.

The dry season in Hoi An usually lasts from February to April or May. This period is dominated by sunny weather with minimal rainfall, creating ideal conditions for strolling through ancient streets and relaxing on the beach. Air temperatures gradually rise, peaking in the summer months. From May to August, it gets hotter, and although rains are not yet as frequent as in the monsoon season, the likelihood of short-term downpours increases.

The wet season, or rainy season, typically begins in September and continues through January. This period is marked by a significant increase in precipitation and rainy days, with the peak occurring in October and November. Despite the rain, air temperatures remain comfortable, although they drop slightly compared to the summer months. Humidity is elevated during this time of year. Understanding these seasonal variations will help you better plan your trip to the charming Hoi An.

Average monthly temperatures in Hoi An range from approximately 21.9°C in January to 30.6°C in June throughout the year, showcasing a warm climate year-round with distinct seasonal features. The hottest months are traditionally June and August, when average daytime temperatures confidently exceed 30°C, with maximum values reaching 33-34°C. The coolest period is considered to be January, with an average temperature of around 22°C; December and February also feature similar, milder temperatures.

The summer months in Hoi An, especially from May to August, are characterized by hot and humid weather. Average maximum temperatures during this period consistently stay above 30-32°C, while minimum nighttime temperatures rarely drop below 26-27°C, creating a sense of tropical heat. Conversely, the winter season, covering December, January, and February, brings a milder and more comfortable coolness. Average daytime temperatures during this time range between 23-25°C, while nighttime temperatures drop to a pleasant 20-21°C, making this period very attractive for those who prefer to avoid extreme heat.

Temperature fluctuations between day and night in Hoi An are generally moderate. The largest difference between maximum and minimum figures is observed in the drier and hotter months (April–August), reaching from 5.7°C to 6.4°C. In the cooler and wetter months (October–December), this difference narrows, ranging from 2.8°C in December to approximately 3.7°C in October. Overall, even during the hottest periods, the nights bring some relief, though they remain warm. Understanding these temperature nuances will help you choose the right wardrobe and plan your activities during your visit to this charming Vietnamese city.

Hoi An experiences a distinct seasonality in precipitation, which is important to consider when planning your trip. The driest period falls between February and April. In February and March, only about 2 mm of precipitation falls, and the number of rainy days is minimal—12 and 10 days respectively. April also remains dry with 3 mm of precipitation and 10 rainy days. May and June bring a slight increase in rainfall (4 mm and 3 mm respectively) and the number of rainy days (16 and 17 days), but overall the weather remains mostly favorable.

The rainy season in Hoi An usually starts in September and reaches its peak in the autumn. In September, the amount of precipitation rises to 10 mm, and the number of rainy days increases to 26. The wettest month is October, with an average of 18 mm of rainfall and rain occurring approximately 27 days. November is also characterized by heavy precipitation (16 mm) and frequent rain (24 days). December rounds out the year with 11 mm of precipitation and 26 rainy days, remaining part of the wet season.

Interestingly, some months, such as January, July, and August, show a high number of rainy days (21-22 days), yet the total amount of precipitation remains moderate—around 5 mm. This may indicate that during these periods, rain falls frequently, but it is less intense or prolonged compared to the peak of the rainy season in October and November. Thus, while the chance of catching rain in these months is high, it may not impact your plans as significantly as during the height of the monsoon.

When planning a trip to Hoi An, remember that the city is in a tropical climate zone, so light and breathable clothing made from natural fabrics (cotton, linen) will be your best choice at any time of year. Be sure to bring sunscreen with high SPF, sunglasses, and a hat to protect yourself from the strong sun. Comfortable walking shoes are a must-have, as exploring the charming streets of Hoi An is best done on foot. Don't forget insect repellent, especially for evening walks.

From approximately February to August, when Hoi An is dominated by drier and hotter weather (average temperatures from 22.8°C in February to 30.6°C in June), your wardrobe should consist mainly of summer essentials: shorts, t-shirts, sundresses, and swimwear. Although rainfall during this period is relatively low (2-5 mm per month from February to August), a light raincoat or compact umbrella can come in handy for sudden short showers, especially from May to August, when the number of rainy days increases significantly (16-22 days). Evenings at the beginning of this period (February-March) can be slightly cooler (minimum temperatures around 20-22°C), so a thin sweater or a shawl wouldn't go amiss.

From September to January, Hoi An enters the rainy season, with peak precipitation in October (18 mm) and November (16 mm), and a high number of rainy days (from 21 to 27 days per month). During this time, a waterproof windbreaker or a high-quality raincoat, along with an umbrella, become absolutely essential. Opt for clothes that dry quickly. Although air temperatures remain warm (averaging from 21.9°C in January to 28.3°C in September), the humidity and rain can make it feel chilly, especially in the evenings of December and January (minimum temperatures around 20-21°C). Therefore, the layering principle in clothing will be very useful: a light sweater or fleece over a t-shirt will help you stay comfortable. Your footwear should also be moisture-ready—consider quick-drying sandals or closed waterproof shoes.
