If you are not afraid of short-term tropical downpours and are looking for milder temperatures, the autumn-winter period also offers many opportunities to get to know this picturesque region.

The climate in the city of Dong Hoi is characterized by a clear division into hot and cooler seasons, which is typical for central Vietnam. The hottest period is summer: temperatures peak in June, when averages reach 30.2°C, and the daytime heat often exceeds the 33°C mark. From May to August, true tropical heat reigns here, persisting even at night, as minimum temperatures during these months rarely drop below 26-27°C.

The winter months bring significant relief and pleasant coolness. January is considered the coldest time of the year, with an average temperature of about 19.4°C. During this period, as well as in February and December, the weather becomes very mild: night-time lows stay around 17-18°C, which is ideal for active tourism, although a light jacket might be needed for evening walks. There are no frosts here, and winter feels more like a warm spring in temperate latitudes.

Transitional seasons in Dong Hoi are distinguished by a comfortable temperature regime. In spring, especially in March and April, the air warms up to a pleasant 23-26°C, creating excellent conditions for travel before the onset of intense heat. Daily temperature fluctuations throughout the year are not too great: the difference between the daily maximum and the nightly minimum is usually only 3-5 degrees, which ensures stable and predictable weather without sudden changes.

The nature of precipitation in Dong Hoi changes significantly depending on the season, which is important to consider when planning a trip. The rainiest and most humid period is autumn. Peak rainfall occurs in October, when not only the highest level of moisture is recorded but also the maximum number of rainy days — an average of about 27 days per month. September and November are also characterized by high humidity, so an umbrella and waterproof clothing will be absolutely essential in autumn.

Winter months and early spring in Dong Hoi have their own specifics: although the total volume of precipitation in millimetres is small, it rains quite often. For example, in January, one can expect up to 22 rainy days. Typically, at this time of year, precipitation takes the form of light drizzle or short-term rains, creating a fresh but overcast atmosphere typical of this region of Vietnam.

The most comfortable time for those who want to avoid rain is summer. June is considered the driest month of the year: the amount of precipitation drops to a minimum, and the number of rainy days falls to approximately 9. The period from April to August is generally characterized by the most stable and dry weather, making it an excellent choice for beach holidays and open-air excursions.

Since hot weather prevails in Dong Hoi from May to August, with daytime temperatures often exceeding 30°C, the basis of your wardrobe should consist of light items made from natural fabrics such as cotton or linen. The sun is particularly active during this period, so be sure to bring a wide-brimmed hat, high-quality sunglasses, and cream with a high SPF level. Also, do not forget swimwear if you plan to relax on the coast.

If your trip falls during the autumn-winter period (from September to January), it is worth preparing for a change in weather. The air temperature becomes more comfortable, dropping on average to 19–20°C, but the number of rainy days increases sharply. At this time of year, it is recommended to use the principle of layering in clothing: a light jacket, windbreaker, or warm jumper will be indispensable on cool evenings. Be sure to pack a compact umbrella or raincoat in your suitcase, as precipitation can be frequent and prolonged.

For sightseeing and walking around the city, choose comfortable, proven flat shoes; if you plan excursions to the region's caves, it is better to prefer closed sneakers with non-slip treads. Given the high humidity throughout the year, it is useful to have a sufficient supply of spare clothes with you, as items may take longer than usual to dry.
