The climate in Con Dao and the best time to go
Con Dao experiences a tropical monsoon climate, characterized by consistently high temperatures and humidity throughout the year, with two clearly defined seasons: the dry season and the rainy season.
This island is best visited during the dry season thanks to the mild and pleasant weather with typical temperatures ranging from 24°C to 30°C (75°F to 86°F). Humidity is also reduced during this time, making it more pleasant to visit the island and engage in outdoor activities.
From March to July, temperature and humidity begin to increase, leading to occasional rain and thunderstorms. The average temperature during this period ranges from 28°C to 33°C (82°F to 91°F), with higher humidity levels.
The months of August to October are the rainy season in Con Dao. This time of year is characterized by frequent heavy rain and harsh ocean conditions, which could disrupt activities such as diving and boat tours. The average temperature during this time generally ranges between 25°C and 30°C (or 77°F and 86°F).
Keep in mind that the weather in Con Dao can be unpredictable and even during the dry season, there may be occasional precipitation. Visitors need to consider the typhoon season, which occurs from June to November and can bring powerful winds and intense rain.
Besides these climatic seasons, there are also distinct tourist seasons.
Generally, the high season extends from November to April, which coincides with the dry season. However, the period between December and February marks the peak of tourism in Con Dao. Since this is the peak season on the island, tourists should expect high rates for accommodation and transportation during this time.
The low season begins from May to October, which corresponds to the rainy season. Meanwhile, Con Dao Island is experiencing a decline in tourist numbers, resulting in lower accommodation and leisure rates than in peak season.
Agriculture does not occupy a dominant place on Con Dao, so there are no specific harvest seasons on the island. Nonetheless, seafood is a major industry in Con Dao, allowing visitors to enjoy fresh seafood all year round.
Keep in mind that Con Dao is a relatively small and remote island, which means it doesn't experience the same seasonal variations as Vietnam's larger cities. Tourists should expect a relatively stable level of activity and tourism throughout the year, but some activities and attractions may be affected by the weather.

What to do on Con Dao Island
Here are the best things to do on Con Dao Island:
Explore Con Dao National Park
Con Dao National Park encompasses more than 80% of the island and is home to a rich diversity of flora and fauna, including rare species such as the Con Dao black squirrel and hawksbill turtle. To explore the park, visitors can follow the hiking trails on their own or book a guided tour to learn about its history and biodiversity.
You can take short hikes to caves, some beaches or ancient trees. But the most interesting route remains the road which leads to the top of the park. On a clear day, you can enjoy panoramic views of the beautiful island here.
Go snorkeling or diving
Although the seas can be rougher in January, the clearer waters allow excellent visibility for snorkeling and diving. Con Dao is among Vietnam's largest diving destinations, with a diverse marine ecology of over 1,300 species of marine life, including coral reefs, colorful fish and even sea turtles.
Visit the Con Dao Museum
Con Dao has a notorious past as a former prison island, even nicknamed hell on earth. The Con Dao Prison Museum will give you an understanding of this horrible era. By displaying the artifacts, the museum highlights the harsh conditions and human rights violations that took place at the prison during the French and American colonial eras.
Relax on the beaches

Observe sea turtles
The remote islands of Con Dao are home to Vietnam's largest population of sea turtles and are home to many protected nesting sites. Every year, these sea turtles travel from the Philippines to Con Dao to breed. Once arriving at Con Dao, female turtles lay around 100 eggs at a time. The Con Dao turtle nesting season runs from May to October and peaks from June to September.
The most popular islands for turtle watching are Bay Canh Island, Tre Lon Island, Cau Island and Tai Island. Bay Canh Island, the large island directly opposite Con Son Island, is the most popular island. If you want to see sea turtles nesting in Con Dao, you should join a turtle tour, organized by the Con Dao National Park Office.
Visit the prisons of Con Dao
One of the must-sees in Con Dao is to visit the old prisons. These prisons were built during the French colonial period and were also used during the Vietnam War to brutally detain and torture political prisoners.
Phu Hai Camp is the largest and oldest on Con Dao island, built in 1862 by the French colonialists. Beyond the cells, common detention rooms, other buildings such as the hairdressing salon, the canteen, the kitchen, the chapel, the stock, the courtyard and the garden were installed to avoid the attention of the Associations of Human Rights. Upon arriving at Phu Hai Prison Center, you can visit room 6, where the highest number of deaths occurred.
The notorious cells, known as "tiger cages", were built by the French in 1940 to imprison nearly 2,000 political prisoners, particularly dangerous revolutionaries. There are 120 rooms where guards could push prisoners around like tigers in a Victorian zoo. You can visit these tiger cages built by the French at Phu Tuong Camp.
Phu Binh Prison, built by the Americans in 1971, is made up of “tiger cages”. This is the most horrible area, each cell is only 5m2 where the hygiene and living conditions were terrible, which caused deaths due to torture, epidemics, diseases and infections.
