November to March
The best time to visit Phuket is during the cool NE monsoon season, from November 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). Note that lately, as almost everywhere in the world, weather is unpredictable.
April to May
The hottest time 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.
June to August
Locals enjoy June, July and August since the weather is usually fine and our 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).
September to October
The rainy season during September and early October we locals start to remember our 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 uncluttered by visitors. And even at this time, we still get long intervals of sunshine between the heavy showers.
