With a tropical monsoon climate, Phu Quoc's weather is divided into two primary seasons: the dry season and the rainy season. This guide delves into the average weather conditions to help you plan the perfect island getaway.
Phu Quoc's climate is consistently warm throughout the year, with average temperatures hovering between 25 and 32 degrees Celsius (77−90∘F). The year is largely defined not by temperature fluctuations, but by the amount of rainfall.

From November, the island begins to dry out, ushering in a period of idyllic weather that lasts until April. This is widely considered the best time to visit Phu Quoc for classic beach holidays.
Average temperatures: During these months, temperatures typically range from a comfortable 25 to 31 degrees Celsius (77−88∘F). December and January are often the coolest and most pleasant months, with lower humidity. As the season progresses towards March and April, temperatures can climb to their peak, sometimes reaching up to 35 degrees Celsius (95∘F).
Rainfall and sunshine: Rainfall is minimal during the dry season. Months like December, January, and February see the least amount of precipitation, ensuring long, uninterrupted days of sunshine. This translates to perfect conditions for sunbathing, swimming, and other water-based activities.
Sea conditions: The sea is generally calm and the water is crystal clear, making it ideal for snorkeling, diving, and island-hopping boat tours. Visibility for underwater exploration is at its best during this time.
This is the high tourist season, so expect more crowds and higher prices for accommodation and flights. Booking in advance is highly recommended.
The rainy season, also known as the green season, begins in May and extends through October. While the name might suggest constant downpours, the reality is often brief, heavy showers, usually in the afternoon.

Average temperatures: The temperature remains warm, averaging between 26 and 32 degrees Celsius (79−90∘F). However, the humidity levels are significantly higher, ranging from 85% to 90%, which can make the heat feel more intense.
Rainfall and sunshine: This season accounts for the majority of the island's annual rainfall. The wettest months are typically July, August, and September, where you might experience more prolonged periods of rain. Despite the showers, there are still plenty of sunny intervals.
Sea conditions: The seas can be rougher during this period due to stronger winds, which may lead to the cancellation of some boat trips. The water clarity might also be reduced compared to the dry season.
The rainy season is the low tourist season, offering a more peaceful experience with fewer crowds. It's also a great time for budget-conscious travelers to take advantage of lower prices on flights and hotels.
