Climate and region of Con Dao
Con Dao is an archipelago in southern Vietnam, about 230 km southeast of Ho Chi Minh City. Known for its pristine beaches, national parks, and marine biodiversity, it is a remote yet rewarding destination for nature lovers.
The climate is tropical monsoon, divided into:
- Dry season (November to April): Little rain, sunny skies, and calm seas—ideal for outdoor activities.
- Rainy season (May to October): High humidity, frequent rain showers, and cloudy skies, though the sea remains relatively calm.
October is a transitional month, meaning rain is still frequent, but the dry season is approaching, and sunny intervals become more common.
Weather in Con Dao in October
October remains warm and humid, with temperatures ranging from 26°C to 31°C (79°F to 88°F). Humidity levels stay high, making it feel warmer than the actual temperature.
Rain is still frequent but slightly less intense than in previous months. Short tropical downpours continue, mainly in the afternoons or evenings, but there are increasingly longer dry periods as the month progresses.
The sea remains relatively calm, and while some days may be too cloudy for ideal diving, the conditions are gradually improving toward the end of the month.
Beach holiday or not?
No, October is still not an ideal month for a beach holiday in Con Dao. While the island’s beaches remain scenic, the rain, overcast skies, and occasional storms make it difficult to enjoy a full beach experience.
If you’re looking for better beach weather in Vietnam during October, options are limited. The southern beaches (such as Mui Ne and Vung Tau) start seeing drier weather towards the end of the month, but most of Vietnam is still in the rainy season. If beach time is a priority, it’s best to wait until November when conditions improve significantly.

Diving in Con Dao in October
Diving is one of the main reasons people visit Con Dao, and October is a transition month for diving. The high season (March to September) is ending, and conditions may be inconsistent depending on the weather.
While the sea remains relatively calm, visibility can be affected by rain runoff, and stronger winds may start appearing toward the end of the month. However, on good days, divers can still see coral reefs, rays, tropical fish, and sea turtles at sites like Bay Canh Island, Hon Tai, and Tre Lon Island.

Turtle watching season
October is one of the last months for turtle watching in Con Dao, as green sea turtles and hawksbill turtles come to nest on the island’s beaches. The nesting season runs from late May to late October, and October offers a chance to witness these majestic creatures, although the likelihood decreases as the month progresses. The best spots to see turtles are on the 14 designated nesting beaches, particularly during the evening hours.
