Climate:
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.
