Con Dao, located in Vietnam, features a distinct tropical climate. It is characterized by high and fairly stable temperatures throughout the year, with average values ranging between 25°C and 28.4°C. This means that travellers can expect warm weather regardless of the time of their visit.

Two main seasons can be distinguished in the climate of Con Dao. The dry season usually lasts from January to March, when rainfall is minimal (0-2 mm) and the number of rainy days is low (1-4 days per month). Starting from April, the amount of precipitation and rainy days gradually increases, transitioning into a distinct rainy season. The peak of the rainy season occurs from May to November, with the highest rainfall (up to 10 mm) and the maximum number of rainy days (up to 28 days per month) in August, September, and October. December is a transition month when the amount of precipitation and rainy days begins to decrease.

Therefore, when planning a trip to Con Dao, it is worth considering these seasonal fluctuations in rainfall. Although the temperature remains comfortably warm year-round, the period from May to November is characterized by a significant probability of rain, which may affect some outdoor activities. The driest and sunniest weather is usually observed in the first months of the year.

The weather in Con Dao is characterized by a warm tropical climate year-round, with slight fluctuations in average monthly temperatures. The annual temperature range here is quite narrow: average temperatures vary from approximately 25.3°C in February, which is the coolest month, to 28.4°C in May, considered the hottest. Thus, even in the "cold" months, very warm weather persists here.

The summer period, which can generally be considered the months from April to October, brings the highest temperatures. In May, the average maximum temperature reaches 29.3°C, while the average temperature holds at 28.4°C.

For example, in January and February, the average temperature is around 25.3-25.4°C, with minimum night-time temperatures rarely dropping below 25.0°C. These months are also characterized by the least amount of rainfall.

One of the features of the temperature pattern in Con Dao is the insignificant difference between day and night temperatures. Data shows that the difference between the average minimum temperature and the average maximum temperature within a single month usually does not exceed one or two degrees Celsius. This means that nights here are just as warm as the days, and no sharp temperature drops are observed, ensuring consistently comfortable conditions for relaxation at any time of day.

When planning a trip to Con Dao, remember that a warm tropical climate awaits you year-round. Average temperatures range from 25°C to 29°C, so the basis of your wardrobe should be light, breathable clothing made from natural fabrics such as cotton or linen.

Con Dao has a distinct rainy season, which usually lasts from May to November, with the highest amount of precipitation and rainy days occurring from June to October. If your trip falls during this time, be sure to bring a light raincoat or poncho and a compact umbrella. Clothing made from quick-drying materials will be especially practical. Also, consider a waterproof bag or case to protect electronics and documents. Footwear that is water-resistant and dries quickly will become your best friend during the frequent, but usually brief, tropical downpours.

From January to April, drier weather settles on the island with minimal rainfall, especially in February and March when rain is practically absent. During this period, the focus shifts to the lightest possible summer clothing. However, even in the dry season, a light cover-up or a long-sleeved shirt may come in handy for protection against the intense sun or in air-conditioned rooms. Regardless of the season, do not forget insect repellent, especially if you plan nature walks in the evening.
