Turtle Nesting Season: June to August
From June to August, Côn Đảo enters its early rainy season, but conditions remain favorable for visitors. Short, heavy showers might occur, usually in the afternoon, clearing quickly. The sea generally stays calm, especially in the mornings. This period is particularly special for turtle watching. Green sea turtles and hawksbill turtles come ashore to nest on beaches like Bãi Cát Lớn and Hòn Bảy Cạnh. Organized tours allow you to observe this natural event respectfully. Diving and snorkeling are still very good, with warm waters. Get a quote for a guided island tour.
Late Rainy Season: September to November
The late rainy season, from September to November, brings more frequent rainfall. However, Côn Đảo often experiences calm seas during these months. The prevailing winds shift, creating sheltered conditions on many beaches. This can still be a good time for diving and snorkeling, especially if you are flexible with your schedule. Rain showers are typically brief, allowing for plenty of sunshine between downpours. Fewer tourists visit during this time, offering a quieter experience. Check local weather forecasts closer to your travel dates. Get a quote for off-peak travel options.
Transition to Dry Season: December to February
December to February marks the transition into the dry season. The weather becomes drier, and temperatures are slightly cooler, especially in December and January. The sea can be choppier on the eastern side of the island due to prevailing northeast winds. However, western beaches often remain calm and enjoyable. This period is still suitable for exploring the island's natural beauty and historical sites. While diving might be less ideal on some days, boat trips to sheltered areas are still possible.
