Complete month-by-month breakdown of Phu Quoc weather, sea conditions, hotel rates, and crowd levels. Find the perfect time for your Vietnamese island escape.
Phu Quoc is Vietnam's largest island and its fastest-growing luxury resort destination. Unlike mainland Vietnam, which has complex regional weather patterns, Phu Quoc has a straightforward two-season climate — making it easier to plan the perfect trip.
Phu Quoc's Two Seasons
Dry season (November–April): Northeast monsoon brings clear skies, calm seas, and the best beach conditions. Peak season December–February sees the highest hotel rates and most visitors.
Wet season (May–October): Southwest monsoon brings heavy rain, rough seas, and significantly lower hotel rates. Some resorts close or reduce services during the wettest months (August–September).
Key fact: Phu Quoc sits in the Gulf of Thailand, which is shallower and calmer than the open South China Sea. Even in wet season, mornings are often clear — rain typically falls in afternoon downpours.
Month-by-Month Breakdown
November: Dry Season Begins — Best Value
Weather: 27–32°C, decreasing rain, seas calming
Crowds: Low-moderate (building toward peak)
Hotel rates: Shoulder (70–80% of peak)
Sea conditions: Good, improving through the month
November marks the transition to dry season. Early November may still see occasional showers, but by mid-month conditions are reliably good. Hotel rates sit well below peak — excellent value for near-peak conditions. Long Beach and Sao Beach are both swimmable.
Best for: Value-conscious travellers, couples seeking good weather without peak-season prices.
December–January: Peak Season
Weather: 26–30°C, minimal rain, calm seas
Crowds: High (very high Christmas/New Year)
Hotel rates: Peak pricing
Sea conditions: Excellent — calm, clear water
December and January deliver Phu Quoc at its best. Calm Gulf of Thailand, clear skies, and perfect beach conditions. Christmas week (December 20–January 5) sees the year's highest hotel rates. The luxury resorts on Long Beach and the north coast are fully booked months in advance.
Best for: First-time visitors, families, honeymooners, beach lovers.
February–March: Still Excellent
Weather: 26–31°C, minimal rain, calm seas
Crowds: Moderate-high
Hotel rates: High (softening from peak)
Sea conditions: Excellent
February and March maintain excellent conditions with slightly fewer crowds than December–January. March is arguably the sweet spot — peak-quality weather, lower rates, and fewer tourists. Snorkelling around An Thoi Islands is at its best.
Best for: Snorkellers, divers, couples seeking peak weather with better value.
April: Transition Month
Weather: 28–33°C, increasing humidity, occasional showers
Crowds: Low-moderate
Hotel rates: Shoulder
Sea conditions: Good, some afternoon chop
April marks the transition. Temperatures rise, humidity increases, and the first signs of the southwest monsoon appear. Beach conditions remain good in the mornings. Hotel rates drop noticeably — good value for those who don't mind occasional afternoon rain.
Best for: Budget-conscious travellers, those flexible on weather.
May–June: Wet Season Arrives
Weather: 27–32°C, increasing rain, roughening seas
Crowds: Low
Hotel rates: Low season (30–40% below peak)
Sea conditions: Rough on west coast, calmer on east
May brings the southwest monsoon. Rain increases significantly, and the west coast (Long Beach) sees rougher seas. The east coast (Bai Thom, Ganh Dau) remains calmer. Some beach clubs and water sports operators reduce hours.
The upside: A beachfront villa that costs $400/night in January drops to $200–250 in May.
July–August: Deep Wet Season
Weather: 26–30°C, heavy rain, rough seas
Crowds: Very low
Hotel rates: Lowest of the year (40–50% below peak)
Sea conditions: Rough — swimming not recommended on west coast
July and August are the wettest months. Heavy afternoon downpours are common. The west coast beaches are rough and not suitable for swimming. Some smaller resorts close for maintenance. However, the island's interior — pepper farms, fish sauce factories, national park — remains accessible.
Best for: Budget travellers, those interested in culture over beaches, resort guests who want maximum value.
September–October: Wet Season Continues
Weather: 26–30°C, heavy rain easing in October
Crowds: Very low
Hotel rates: Low season
Sea conditions: Improving in October
September is typically the wettest month. October sees conditions begin to improve — rain decreases and seas start to calm. By late October, the transition back to dry season is underway. Hotel rates remain low, making late October an excellent value window.
Best for: Value hunters, travellers who can tolerate some rain for significantly lower prices.
