The best times for a diving trip in Vietnam

The best time to dive along the East Sea beaches, including Danang, Hoi An, Ly Son, Whale Island in Nha Trang, and the Con Dao Archipelago, is from March to August. The weather is dry and sunny during this period, and the sea is calm. The summer months, especially June, July, and August, offer the best diving conditions with clear water, making it easy to observe a variety of colorful tropical fish and beautiful corals.

However, the rainy season lasts from September to February. During this time, the weather is dreary and the sea is rough, making it unsuitable for diving. Many days of heavy rain result in zero visibility, especially during storms. Additionally, the waves can stir the bottom, further reducing visibility. A lot of diving services also close from mid-September or October to February.

In contrast, snorkeling spots in the south, such as the Gulf of Thailand islands like Phu Quoc, are ideal from November to May of the following year. Therefore, carefully plan your diving trip in Vietnam to make the most of your experience!
