The seasons, month by month
A rough reading of the table. Season edges are not sharp, so treat the dates as a guide.
December to March: the driest months
December has 76.9 mm, January 31.0 mm, February 20.6 mm and March 89.5 mm. These are the four lowest totals of the year, and the usual choice for beach days and boat trips.
April and May: hotter, with rain building
April and May are the warmest months at 84.2°F (29.0°C). Rainfall rises from 137.0 mm in April to 230.4 mm in May.
June to October: the rainy months
Totals run from 325.6 mm in October to 542.3 mm in September. Expect frequent heavy rain, and keep your plans flexible.
November: the change
November has 179.9 mm, clearly drier than September and October but wetter than January or February. Do not treat it as guaranteed dry.
Best time to visit Phu Quoc
The national tourism organization names November to April as the favorable period. That matches the table, with one caution: November is still wetter than the months that follow. If your main aim is beach weather, December to March gives the lowest rainfall. An older JICA report puts the rainy season at May to November and the dry season at December to April, which fits the same picture. These dates describe a season, not a promise for a given beach on a given day.
If you travel in the rainy months, plan around the weather. Keep the cable car, the parks and the evening shows flexible, and read the pages on the Hon Thom cable car, VinWonders and Sunset Town for what changes with the weather. The evening shows at Sunset Town cannot be counted on in every kind of weather.
Weather and the sea
Weather matters more on the water than on land. On 14 August 2026, ferry links between the mainland (Rach Gia and Ha Tien) and Phu Quoc, and between Phu Quoc and Tho Chau, were suspended for a time because of wind and waves. Service resumes only when conditions are judged safe. Boat tour operators may change the route or cancel because of weather, and one operator states that it refunds a trip if the authorities forbid sailing.
After a boat accident in July 2026, the provincial construction and transport authority requires passengers to wear life jackets before the boat leaves the dock. Put yours on when you board and follow the crew. For trips to the An Thoi islands, see our snorkeling page.
