Phuket has only two seasons - the wet and the dry. Weather conditions are at their best in Phuket from November to March, when a cooling wind keeps the heat at bay and humidity level is low here. From March to May the temperature rises as the cooling wind departs and the humidity rises.
In April monsoonal weather usually arrives to Phuket, which is expected to last until October. Peak rainfall levels are usually experienced in September and October. Outside of these months, the rain can often come in a short, heavy shower, usually in the afternoon.
Phuket has similar weather conditions with other West coast destinations throughout the year as they all experience the impact of the Andaman sea. Temperatures and weather conditions in these locations might differ a bit in short term but in long term it's not notable so you can easily combine a visit to Phuket with other nearby destinations like Koh Phi Phi or Krabi.
