Phu Quoc weather in December is generally warm with far fewer heavy rains than during the monsoon months, making it a popular month for beach activity and island excursions. Travelers can expect daytime highs in the high 20s°C, calm seas, and a festive atmosphere around the holidays—conditions that suit outdoor plans and water-based activities.
Phu Quoc weather in December: background and seasonal context
December marks the transition into the island's dry season. Average temperatures sit near 27.3°C (81.1°F) overall, with daytime readings commonly between 28–30°C (82–86°F) and night temperatures cooling to about 25°C (77°F). Compared with the hot, humid period of July through September, December typically feels milder and more comfortable.
Rainfall decreases sharply in December. The island usually records around 8–9 rainy days in the month, with total precipitation often reported between roughly 48 mm and just over 100 mm. Most showers tend to be short-lived, commonly showing up late in the afternoon or at night, so they rarely disrupt daytime plans.
Key features and highlights of December weather
Humidity in December drops compared with the wet season, averaging close to 72 percent, which many visitors find noticeably less oppressive than during peak monsoon months. Sea conditions become calmer and visibility for diving and snorkeling often improves—reports indicate underwater visibility can reach 15–20 metres around late November and December.
Air quality on the island is generally good in this month; typical Air Quality Index (AQI) readings are low, making outdoor activity easier for people sensitive to pollution. However, the UV index remains high—commonly between 7 and 9 during midday—so reliable sun protection is still important.

Practical tips for traveling to Phu Quoc in December
Pack lightweight clothing for daytime, plus a light layer for cooler evenings. Sunscreen, a wide-brimmed hat and sunglasses remain essential because of the strong midday sun. Although rain is less frequent, keep a compact raincoat or umbrella handy for short showers that can appear in the late afternoon or evening.
If you plan to buy local goods such as cultured pearls, inspect quality carefully and ask vendors about guarantees—tourists sometimes report variable product standards. For water safety: swimmers should be cautious about waves in certain areas and avoid venturing too far from shore without local guidance.
Entry requirements and travel advisories can shift. For the latest on visa and arrival procedures, check official guidance before you travel; readers may find the information on entry rules useful when preparing their trip.
Cultural context and seasonal events
December coincides with end-of-year holidays, and many resorts and restaurants stage special dinners, live music and countdown events. These festivities tend to be concentrated near larger hotels and the island’s main towns, so expect higher activity there as New Year approaches.
Local markets remain lively in the evenings; the island’s night market is a regular draw for food stalls, inexpensive local dishes and casual souvenir shopping. For a deeper look at island food culture and market life, plan to arrive with an open schedule so you can sample street fare and chat with stallholders.
Who should visit Phu Quoc in December?
December suits travelers who prefer warm weather without the heavy rains of the wet season: beachgoers, snorkelers and families looking for stable sea conditions will likely find the month favorable. It also appeals to visitors seeking festive holiday events combined with outdoor options.
Those wanting quieter, lower-cost travel should be aware that December is a popular month, particularly around Christmas and New Year’s. Early-month visits or midweek stays can help avoid peak occupancy at major hotels and attractions.
Comparisons and alternatives
For planning, it helps to contrast December with other seasonal periods on the island. July to September is typically hotter and more humid with more frequent heavy rain, while the mid-to-late dry season (January–March) often offers similarly good conditions for water activities.
If your travel dates are flexible, consider the trade-offs between slightly cooler, less rainy December weather and the very low rainfall of later dry-season months when the island may be busier. The following table summarizes practical differences by period.
| Period | Avg daytime temp | Rainfall | Humidity | Sea conditions | Typical crowding |
|---|---|---|---|---|---|
| December | About 28–30°C | Lower (approx. 48–104 mm) | Moderate (~72%) | Generally calm; good visibility | High around holidays |
| July–September | Hotter (peak heat) | Frequent heavy rain | High (humid) | Rougher seas at times | Lower than December |
| January–March | Warm and comfortable | Low | Lower | Excellent for diving/snorkeling | Busy, but varies |
