How is the Weather in Phuket in September?
September is usually the wettest month of the year in Phuket. You can expect more rainy days than sunny ones, but you still can expect a mix of sun and rain. If you dream of blue skies over a quiet blue sea and have the choice of your travel dates, September may not be the best month to visit Phuket. As always, Phuket Weather is unpredictable each year!
There are still some bright sides if you have no choice: the roads are not hectic, all the attractions are open, and the tours and excursions operate normally. Except for the Similan Islands, all the islands around are open, including Phi Phi Island. Everything is cheaper, bargaining is easy, and you can get a better room in any hotel at better prices.

The rainy season pattern changes yearly, and your week can be surprisingly sunny; no one can predict it. The best way to manage your holiday is to take advantage of each clear day to spend on the beach. As usual, respect the flags, don’t underestimate how powerful riptides are, and swim in your swimming pool if the flags are red.
On a cloudy day, you can explore Old Phuket Town, or if it rains, you can book a spa treatment at your hotel. Remember to book as early as possible when you suspect the rain is here to stay because everyone will have the same idea! First booked, first served!
