Phuket Weather & Seasons

Phuket weather and its seasons can be broken down into 2 seasons – wet and dry. When planning your trip it’s essential to know when the seasons run to and from, to ensure your stay is a pleasant and comfortable one. Although Thailand is generally a hot sunny place to be all year-round, there are some months that can be better than others. This weather guide can also be used if you are planning a trip to other islands in Thailand, such as Koh Chang, Koh Phangan, Koh Lipe or Koh Tao. Although there are two seasons, the temperature tends to remain fairly constant year round, averaging between 25-35c.

The Dry Season

The dry season generally runs from late December until May. Most crowds flock to Phuket between December and March when endless clear blue skies can be almost guaranteed and rainfall is at its minimum. This is also the peak season when European visitors arrive seeking sun from the winter weather in their homelands. Expect to pay more for your accommodation between this period too. Daytime temperatures rarely drop below 26c but the humidity is a lot cooler in these months. You may even find you need a light pullover in the evenings.

It doesn’t get any hotter than between the months of March and May. For those who like it baking hot, this is the best time to visit. During these months the temperatures here can be very hot and humid; keeping cool can be a challenge. Staying somewhere with a sea breeze is advisable.

The Wet Season

It’s rare it will rain all day in Phuket during the wet season; a late afternoon thunderstorm is about the height of what to expect during the months of June and September. There is always plenty of sunshine to be enjoyed, along with comfortable temperatures. From September onwards you can expect the temperature to drop a little. However, bare in mind it will still be hot. The monsoons historically come to the Gulf of Thailand during October/November and this can often result in the heavens opening up for a few days at a time. Storms become more frequent around late afternoon and early evening.

Due to the heavy rainfall, high seas and prevailing winds, November is the cheapest time to visit the island. Those not deterred by the Phuket weather at certain times of the year should look out for the bargain holidays to the island during the wettest months.
