When is the Best Time to Go to Phuket

Whether Phuket has a tropical monsoonal climate. It’s warm all year round, but the two periods of April-May and September-October are the hottest. The September-October period is also the wettest due to the southwest monsoon.Phuket is blessed by being in a temperate zone. Even though typhoons and tropical storms occasionally batter Hong Kong and the Philippines, Phuket enjoys mild weather and while the heavier rains in September and October can disrupt things a little, it’s rare that the island has several consecutive days of heavy rain.



Average Temperature in Phuket

Phuket is located south of the Tropic of Cancer and north of the Equator in what is known as the Tropics. Due to it’s location, Phuket experiences exceptionally good weather throughout the year.
The average temperature throughout the year ranges from about 27 degrees Celsius to about 30 degrees Celsius or 81 to 86 degrees Fahrenheit. Basically, the temperature is fairly constant throughout the year.

Hottest Time in Phuket is from April through May with temperatures ranging from 80F to 95F (27C to 36C). There are frequent short heavy thundery showers, offering welcome relief from the temperature and humidity. The Thai New Year occurs (Songkran Festival) on April 13th and everyone sprinkles (or throws) cool water on each other.

In June, July and August the weather is usually fine and the island’s favourite haunts remain uncrowded. The usual pattern is brief but heavy showers, with plenty of sunshine between downpours. Everything is a little less expensive at this time of year, as well. Temperatures range between 70F and 90F (20C to 33C).

Water Temperatures

Water temperatures at the surface range from 26 – 29°C (79 – 84°F). During March and April, unpredictable thermoclines may cause a temporary drop of a few degrees, though at depth this can be as much as 10°C (18°F).

Best Time to Go to Phuket

The best time to visit Phuket is during the cool NE monsoon season, from December through March, when it isn’t so humid, and the cool breezes keep things comfortable. The average temperature is around 75F to 89F (24C to 32C).

Low Season

During September and early October locals start to remember their umbrellas. This makes an ideal time to visit abroad. One consolation for those who remain is that the beaches, outdoor restaurants and streets are relatively quieter. And even at this time, there are still long intervals of sunshine between the heavy showers.
There are plenty of low season activities, both water- and land-based, are available on Phuket during this wettest part of the summer season.
