Weather

Phuket has a tropical monsoon climate, and is warm all year long averaging temperatures of around 29C (88F). The climate is hot and humid throughout the year.

The high season is generally considered to be from November to May. During the summer monsoon season, mornings and afternoons are still sunny and clear, but it tends to rain in the evenings and water clarity goes down. Locals consider May to October the "cool" season, and the weather is quite tolerable, much more so than in the tourism centers around the Gulf coast. It's comparable to Florida's summer weather in temperature and intensity of rain storms: 25-33 deg C, flying clouds, short and thunderous rainfalls in the afternoons and evenings. Surfing is possible off the western beaches.
