Phu Quoc weather follows two clear seasons. The dry season runs from November to April: plenty of sun, little rain and a calm west coast. The rainy season runs from May to October, wettest from about July to September, with rougher seas on the west side. If you can only pick one window, December to March is the best time for beaches and island-hopping.
Rainy season doesn't mean rain all day, though. Knowing the rhythm helps you dodge crowds and save money at the same time.
Dry season (November to April): sunny, calm, busy
The northeast monsoon brings dry air and average temperatures around 27–28°C. January to March is the golden stretch: almost no rain, long sunny days and clear water. It's also when rooms cost the most, so book early, especially around Lunar New Year.
April is the hottest month, with some days reaching around 33°C. If you travel then, stay out of the midday sun.
Rainy season (May to October): quieter and cheaper
The southwest monsoon brings the rain. The peak is July to September, when some months see more than 20 rainy days. Even so, island rain usually arrives as tropical bursts of an hour or two, often in the afternoon or at night, followed by sunshine.
On the plus side: fewer visitors, lower prices and lush green scenery. On the minus side: some boat trips get moved or cancelled when the sea is rough, and the west coast tends to be choppier than the east.
Shoulder months: April and October
The two changeover months are often a sweet spot, not yet too hot or already less rainy, with prices below the peak. If your dates are flexible, they're worth a look.
What to wear in each season
Dry season: light, bright clothes, a hat, sunscreen and a spare swimsuit. Rainy season: quick-dry fabrics, a packable rain jacket and a waterproof phone pouch.
Humid air means clothes hung in a hotel room take ages to dry and can start to smell. In the rainy season, machine washing and drying is the quickest way to get properly dry clothes. In Duong Dong, NightGo Laundry is open 24/7 and returns laundry dried and folded in 3–4 hours, or 1–2 hours with express.
