Climate of Phuket :
  Phuket has three major seasons:

Rainy Season from June through October.
Cool Season from November through March.
Warm season from April through May.

  There are many sunny days throughout the rainy season too. Since it is warm rain the temperature does not differ that much between the three seasons. It is quite pleasant to sit under an umbrella, and see the rains cooling the dry lands and smell that special newly wet grass.
