When to go à Phuket ?
The average temperatures vary little during the year: 21/32°C. The driest month is February, the one with the most rainfall is September. The mainland and the Andaman coast have three seasons. The dry season, November/March, is the most pleasant (27°C on average). The rainy season, June/October, heavy and humid with thunderstorms at the end of the day, is still bearable. A third season, quite short (April/May) precedes the arrival of the monsoon: it is the heat wave (32°C) with rare rainfall, more difficult to bear.
From December to March: the dry season is pleasant, the hotels are full with many tourists from Germany in particular, and prices at their maximum. From June to September: it is the period of the European summer holidays. Prices are at their lowest in Phuket, Koh Lanta and Koh Samui are crammed with tourists. Less people in Koh Pha Ngan, Koh Tao or Koh Chang. This is the preferred season for Italians who join the loyal Anglo-Saxons of the destination. From October to November: there are never many people, and yet it is the most pleasant season. Phuket, Koh Phi Phi Phi, Krabi and the whole Andaman coast are then particularly welcoming, at a lower cost. Hotel rates do not really start to rise until mid-November. This is really the best time in Southeast Asia, for those lucky enough to be able to choose these dates.
