Climate and region of Con Dao
Con Dao is a remote archipelago in southern Vietnam, about 230 km southeast of Ho Chi Minh City. The islands are known for their untouched natural beauty, protected marine areas, and historical significance, making them a unique travel destination.
The climate of Con Dao is tropical monsoon, with two distinct seasons:
- Dry season (November to April): Characterized by minimal rainfall, sunny days, and calm seas, making it the best time for beach and outdoor activities.
- Rainy season (May to October): Brings higher humidity, tropical showers, and overcast skies, though the sea remains relatively calm due to the island’s location.
June is fully within the rainy season, meaning visitors should expect a mix of sunshine, cloud cover, and brief but heavy rain showers.
Weather in Con Dao in June
June is hot and humid, with temperatures ranging from 27°C to 32°C (81°F to 90°F). While mornings can still be bright and sunny, rain showers become more frequent, especially in the afternoons.
Rain typically doesn’t last all day, but expect short, heavy tropical downpours, often lasting 30 minutes to an hour. The humidity is high, making it feel warmer than the actual temperature.
The sea remains calm enough for diving, but the overcast skies and rain can affect visibility on some days.
Beach holiday or not?
No, June is not a great month for a beach holiday in Con Dao. While the island’s beaches remain beautiful, the rainy weather and high humidity can make sunbathing and swimming less enjoyable. Overcast skies also reduce the chances of enjoying the turquoise waters and white sand beaches in their best conditions.
Travel tip: If you’re looking for better beach weather in Vietnam during June, head to the central coast, where destinations like Hoi An, Da Nang, Nha Trang, and Quy Nhon experience ideal sunny conditions.

Diving in Con Dao in June
Diving remains one of the highlights of Con Dao in June, as it is still within the high season for diving (March to September). Despite occasional rain, the sea remains calm, and underwater visibility is generally good (15–20 meters).
Divers can expect to see coral reefs, rays, sea turtles, and tropical fish, with many sheltered dive sites that remain accessible even during rain showers. Bay Canh Island, Hon Tai, and Tre Lon Island are some of the top diving spots during this season.

Turtle watching season
June is one of the best months for turtle watching in Con Dao. The green sea turtles and hawksbill turtles begin their nesting season in late May, and by June, more turtles are coming ashore to lay eggs on the protected beaches.
Turtle conservation programs on Bay Canh Island and Hon Cau Island offer visitors a chance to witness turtles laying eggs at night or see baby turtles hatching and making their way to the sea. This is a rare and unforgettable wildlife experience.

Is Con Dao worth visiting in June?
June is not the best month for general tourism in Con Dao, but it is worth visiting if you are interested in diving or turtle watching.
- Not ideal for beach holidays: Due to the increased rain and cloud cover, beachgoers may not get the perfect tropical island experience.
- Good for diving: Despite the rainy season, diving conditions remain good, and marine life is active.
- Excellent for turtle watching: If you want to see turtles nesting, June is a great time to visit, with organized tours available to observe this unique natural event.
If you’re looking for a classic beach vacation with sunny weather, it’s better to choose Vietnam’s central coast (Hoi An, Da Nang, Nha Trang, or Quy Nhon) in June. But if you’re interested in wildlife experiences or diving, Con Dao is still a great option this month.
