Climate in Con Dao (Vietnam)

The Con Dao Islands experience a tropical climate, hot all year round, with a rainy season from May to November and a dry season from January to April. From May to August there is the south-west monsoon, and from September to December the north-east monsoon. Both monsoons bring rainfall to these islands, and the one from May to August also brings lively winds. In December, the rains become quite rare, although it depends on the year.
The islands are located to the south of the southern coast of Vietnam, at almost 9 degrees north latitude.



Here are the average temperatures recorded on the main island, Côn Sơn.

Precipitation amounts to 2,000 mm (78 inches) a year, and is abundant from May to November.

The sun shines especially in the dry period, from January to April, while the sunshine hours decrease in the rainy period.

The sea temperature is warm enough for swimming all year round.

The Con Dao Islands can be affected by typhoons, the tropical cyclones of the western Pacific. In southern Vietnam, typhoons generally occur from October 15 to December 20, with a maximum in early November.
In January, and again from mid-March to mid-April, some tropical depressions can occasionally form, generally off the central-southern coast of Vietnam, but they almost always dissipate over the sea before reaching the coast. However, they can cause abnormal waves. Anyway, sometimes they can reach the coast.
