Phu Quoc month by month

The pattern is a mirror. When the southwest wind blows, from roughly May into October, Long Beach, Bai Dai and Ganh Dau get the waves and murky water while Bai Sao and Bai Khem, tucked into bays on the south-east, stay calm. When the northeast monsoon sets in, the west coast flattens and the east side takes the wind. The details are on West coast or east coast.

These are the months most guides recommend, and the numbers explain why: January and February each average under 30 mm of rain. The west coast is at its calmest, which is what most hotels on Long Beach and Ong Lang are built around. Sunsets fall between about 17:49 in late December and about 18:02 in mid-January, so a sunset drink is early by European standards.

It is also the island's busiest stretch for foreign visitors. On 17 January 2026 the airport handled 47 international flights in a day; on 14 February 2026, the first day of the Tet break, it received 86 arriving flights, 50 of them international. The east side can be windy when the northeast monsoon is strong, and boats from the mainland are sometimes held in port: in November 2025 the fast boats from Rach Gia and Ha Tien were stopped for gusts of force 7 to 8 and waves of 1.5 to 2.5 m.

The southwest monsoon months. Rain tends to come in spells, sometimes three or four wet days and then a dry week, but the sea on the west coast is often too rough for swimming and the water turns cloudy. A resort worker and a local guide quoted by VnExpress advise staying in the south, around Bai Sao and Bai Khem, in this season. Local people quoted in a 2024 VnExpress report put Bai Khem's calm months at June to September.

Hotel rates are lower on average in this half of the year, but the 2 September National Day break fills the island anyway. For 2 September 2026 the airport expected about 570 flights and 84,800 passengers over the holiday, with 148 flights on the peak day. The Mid-Autumn festival falls on the 15th day of the eighth lunar month and is mostly a family and children's evening.

• Short trips of two or three nights. A single windy front can take out the beach days you planned, whatever the month. Choose a base where the evenings work without the sea.
• Boat days to the An Thoi islands. They depend on that day's wind and waves, not the month. After a canoe capsized on 11 July 2026 on the way back to An Thoi, the special zone ordered that boats must not leave in bad weather.
• Fixed holiday dates. If you can only travel over Tet or 2 September, the crowd matters more than the weather. Read Peak dates first.
• Rain as a deal-breaker. Even the drier months have showers, and the long-term averages hide year-to-year swings. Check a short-range forecast in the week before you go.
