1. An overview of Con Dao Vietnam’s weather

Con Dao has a tropical climate, which results in two distinct seasons: a dry season and a rainy season. The average temperature throughout the year is a warm 26°C (79°F), with humidity levels hovering around 90%.​

• Dry Season (December – April): This period is characterized by less rainfall, clearer skies, and more sunshine, with average temperatures between 24°C and 30°C (75°F to 86°F). Travelers we have guided often praise this season for its comfortable weather, which is perfect for sightseeing.​
• Rainy Season (May – November): This season brings more frequent rain, though it often comes in short bursts during the afternoon. Despite the rain, the period from March to September sees the calmest seas, a detail many visitors appreciate. It is also important to be aware that the islands can be affected by typhoons, typically from mid-October to late December.​

2. When is the best time to visit Con Dao Vietnam? 

Determining the best time to visit Con Dao Vietnam truly depends on your travel priorities. Based on our extensive experience, we help travelers choose the period that best matches their interests.​

2.1. For the dry season (December – April)

If your priority is sunny weather for land-based activities, the dry season is your best time to visit Con Dao Vietnam.

• One visitor on Tripadvisor noted that January is an “ideal time” for visiting the south of Vietnam, including Con Dao, as it typically brings “clear blue skies all the way”. This makes it perfect for those who want to maximize their time outdoors without worrying about rain.​

• The period from November to April is perfect for snorkeling, diving and trekking due to the cool and dry weather. A traveler, Ms. Chloé, also mentioned this period as “peak season for a reason,” highlighting the clear skies and calm seas on the west side of the island.​

2.2. For the rainy season (May – November)

While it may seem counterintuitive, many experienced travelers and locals recommend the rainy season, especially from March to September, for its calmer seas, water activities, and the chance to see nesting turtles. 

• Based on Vietnam Motorbike Tour team‘s experience, while this period is technically the rainy season, the seas are at their calmest, making it the best time for sea activities like exploring uninhabited islands and snorkeling. Rains are often short and don’t last more than an hour, leaving the rest of the day sunny. This is echoed by other visitors who found the rains to be brief and refreshing.​

• This period is also the turtle spawning season, a major draw for many visitors. As one guide points out, this is an “unmissable experience”.​

3. Things to do in Con Dao Vietnam by season

4. What to pack when visiting Con Dao Vietnam?

Packing correctly is essential for a comfortable and enjoyable trip to Con Dao. Based on our years of experience, here are our recommendations:​

• Clothing: Lightweight, breathable clothing is a must for Vietnam’s tropical climate. Pack shorts, t-shirts, and at least one pair of long pants for visiting temples or for cooler evenings. A swimsuit is essential for the beautiful beaches, and a light jacket or cardigan is useful for air-conditioned spaces. If visiting during the rainy season, a rain jacket or poncho is highly recommended.​
• Footwear: Comfortable walking shoes are crucial for sightseeing and any hiking you plan to do. Sandals or flip-flops are perfect for more casual outings and relaxing on the beach.​
• Health and Toiletries: Sunscreen is non-negotiable to protect against the strong sun. Also, pack insect repellent, especially for jungle treks. A basic medical kit with pain relievers, motion sickness pills, and any personal prescription drugs is always a good idea. While most hotels provide basic toiletries, you may want to bring your own to reduce plastic waste.​
• Essentials: Don’t forget a sun hat, sunglasses, and a reusable water bottle. A waterproof phone case and a reliable day bag are also very practical for excursions. Vietnam uses 220V electricity and two-pronged plugs are common, so bring a universal adapter if needed.​

In summary, the best time to visit Con Dao Vietnam is entirely dependent on the experience you seek. Whether you prefer the sunny, dry months for trekking or the calm seas of the rainy season for diving, Con Dao is a remarkable destination year-round.
