Phuket is in the south of Thailand and close to the Equator that made Phuket had three seasons is the cool season, the hot season, and the rainy season. The climate is affected by the monsoon winds, which are the direction of the prevailing winds caused by the difference in the way oceans and land heat.
The great land mass of Asia is warmer than the Indian Ocean from May to November. The colder, heavier air over the Indian Ocean pushes into the warm air over the continental land mass. This causes the prevailing winds to come from the southwest over the Indian Ocean, bringing lots of warm moist air and therefore lots of rain.
Then as the Asian continent cools from November to April, the ocean becomes warmer than the land. The prevailing wind direction changes to come from the northeast. That is from the great land mass of China bringing cooler, drier air and good weather. The result is a fairly predictable weather pattern.

The Cool Season
From November to February the weather is cool season. The northeast winds normally start sometime in November bringing an end to the rainy season. The cool season is the best time of year to visit Phuket. There is lots of blue sky, very little rainfall, lower humidity and the temperatures are comfortably hot. This is Phuket's high-season with the peak of visitors coming over the Christmas and New Year period.

The Hot Season

The hot season is from March to early May. The weather is dry and the skies blue but many people find the temperature is a little too hot for comfort. This is mid-season for Phuket. There are still a lot of visitors but the hotels start to lower their rates around this period as demand drops.

The Rainy Season

The monsoon winds from the southwest start in early May and bring the rain. The highest rainfall comes in May, September and October. In these months it can rain for long periods. These three months are definitely not the time of year to come if you want sun or outdoor activities. However, June, July and August are good months to visit. During these three months, there will be plenty of rain but it usually falls in short heavy bursts. In between, the weather is pleasant with comfortable temperatures and a cooling breeze. There will often be periods of several days without any rain.
