Average weather, temperature, rainfall, sunshine hours
The climate of Phuket is
tropical, hot all year round, with a rainy season due to the southwest monsoon, which lasts from May to October, and a dry season from December to March. In April, before the monsoon, there is a certain increase in showers. In November, there can still be abundant rainfall, especially in the first part, either for any delay in the retreat of the monsoon, or because of a tropical cyclone (see below). However, there may be some showers also in the dry season, especially in December, when occasionally, some of them can be particularly intense.
In an average year, about 2,200 millimeters (87 inches) of
rain fall; on the coast on the Andaman Sea, where Phuket is located, the rains brought by the southwest monsoon are more abundant than on the other coast of peninsular Thailand, that of the Gulf of Siam, since the south-western winds hit it directly. However, the rainy period has two peaks, in the first part (May) and in the last (September-October). During some years, however, there may be torrential rains even in July and August.
Here is the average precipitation.

Phuket, like the rest of Thailand, can sometimes be affected by
tropical cyclones. This area on the Andaman Sea is relatively protected, since
cyclones can be formed nearby, but then, they will head towards the Bay of Bengal, and this happens preferably between April and December, with two peaks at the beginning and at the end of the period (April-June and October-December), while
typhoons can arrive from the east, but they generally pass more to the north, from the South China Sea to mainland Thailand; however, from time to time, they can also move to these latitudes, which has happened in the last few decades from mid-October to about December 20.

Best Time
The
best time to go to Phuket for a beach holiday is the dry season, from late December to March. However, surfers prefer the period from June to September, when waves are higher in the beaches exposed to the west, like Pansea Beach, Karon Beach, and Kata Beach.
