When is the best time to dive in Phú Quốc?

The best time to dive in Phú Quốc is from October to April during the dry season. During these months, water visibility around the island ranges from 10 to 30 meters. The rainy season runs from May to September, bringing southwest monsoons that make waters rough and reduce visibility to less than 5 meters. If you visit during the wet season, diving is often restricted to a few sheltered bays on the eastern side. Sea temperatures remain warm year-round, averaging between 28 and 30 degrees Celsius. You do not need a thick wetsuit; a 3mm shorty or a simple rash guard is usually enough. For current sea conditions during your planned dates, ask a Trip2VN specialist.

Where are the best diving and snorkeling sites in Phú Quốc?

Phú Quốc has two main diving areas: the northern coast and the An Thới Archipelago in the south. The northern sites, near Đồi Mồi Island, are shallow, averaging 10 to 12 meters deep. These shallow waters are ideal for beginners and snorkelers who want to see hard corals and macro life. The southern area features over a dozen small islands with deeper dive sites down to 30 meters. Popular southern spots include Hòn Thơm, Hòn Dầu, and Hòn Nhạn. Here, you will find steep rocky reefs, sea whips, and larger schools of reef fish. Most dive operators depart from An Thới harbor in the south or Dương Đông town.

How much does a Phú Quốc diving trip cost?

A standard two-dive day trip for certified divers starts from $75 (approximate), including equipment and lunch. Snorkeling day trips are cheaper, starting from $30 (approximate) per person. If you want to get certified, a three-day PADI Open Water course starts from $400 (approximate). Prices vary depending on whether you choose a speed boat or a larger wooden boat. Speed boats save travel time but offer a bumpier ride. Large wooden boats are more stable but take longer to reach the southern islands.
