Phuket Weather Guide: When is the Best Time to Visit?

Phuket, a paradise city, is one of the most beautiful places in the world. Since you have visited this city, you would have found an incredible, amazing, and relaxed place to enjoy and experience everything, such as tradition, food, people, and service. However, if you plan to travel to Phuket, you need to plan accordingly due to the change in the Phuket weather.

Phuket Seasons: What Does the Climate Look Like Year-Round?

Phuket weather calendar

Phuket weather is warm throughout the year, with temperatures generally ranging between 25°C – 34°C (77°F – 93°F). The climate is typically characterized by two main seasons—a dry season and a rainy season—with transitional periods in between. The seasons are changed by the tropical monsoon, which is characterized by prevailing winds from the northeast for half the year, then the southwest for the remainder of the year, causing a dry and rainy season.

When planning a trip to Phuket, it's essential to understand the weather changes and prepare accordingly. Here is the year-round weather forecast in Phuket!

Dry season in Phuket 

The dry season begins in December and usually lasts until March. This period is influenced by the northeast monsoon, which brings cool, dry air from the Asian continent and leads to a minor decrease in temperature.

Tourists will enjoy the gentle breezes, calm seas, and clear skies. It is also the coolest time of the year.

Transitional Periods

It’s hard to predict the transitional periods between dry and rainy seasons. The hottest time of the year occurs just after the dry season, typically in April, with highly variable rainfall. The transition period in November is generally cooler and wetter in Phuket

Rainy season in Phuket 

The rainy season begins in May through October. People are usually familiar with the monsoon, which occurs from the southwest. This monsoon brings strong winds that carry warm, moist air and plenty of rainfall from the Indian Ocean.


What is the Best Season to Visit?

High season

The dry season in Phuket really brings the best weather of the year. Visitors can enjoy super clear skies, calm seas, and gentle breezes. Furthermore, the temperatures are at their most comfortable, making it a perfect time for a visit!

The peak season in Phuket is December and January, which means accommodation prices will be higher. Dry season is also the time of the year when the Similan Islands are opened and when you can expect the best dives in Phi Phi Island. Patong Beach also has its best atmosphere during these months.

Low season

In the rainy season, the southwest monsoon brings challenging conditions to the seas around the island, typically rough waters with two-meter seas and frequent rain squalls. 

These conditions often impact boat traveling, for example, boat tours and ferries to nearby islands are often cancelled or delayed due to safety concerns.

For diving and snorkeling, rough sea conditions can reduce underwater visibility as stirred-up silt affects clarity, and stormy weather may limit access to exposed dive sites. While good visibility is still possible on calmer days, conditions are less predictable during this season.

September is typically the wettest month in Phuket, experiencing the highest rainfall of the year. Despite this, many residents continue their normal daily life, as rainfall usually occurs in short, heavy bursts rather than continuous rain.
