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 in September 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.

Sea Condition
September brings rougher sea conditions to Phuket due to the southwest monsoon. Waters remain warm at 29°C but become choppy and unsuitable for swimming on the west coast. The Andaman Sea experiences wave heights of 2-3 metres, leading to red flag warnings at popular beaches like Patong, Kata, Karon, and Surin due to strong currents and waves.
However, visitors can still enjoy calmer waters on Phuket’s east coast. Beaches, including Panwa Beach and Ao Yon Beach, offer safer swimming alternatives with their natural protection from monsoon swells. These sheltered areas experience much smaller waves even during strong wind conditions, making them ideal for families and less confident swimmers.
The contrast between coasts is notable during September, while west-facing beaches face the full force of monsoon conditions with dangerous rip currents, while east coast locations provide peaceful swimming experiences.
What to Do in Phuket in September?
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!
Book an Amazing Spa Treatment!
When rain hits Phuket, we suggest booking a spa treatment at your hotel. September is perfect for experiencing one of Phuket’s award-winning spas without missing beach time. Many resorts feature world-class wellness centres with traditional Thai massages and rejuvenating treatments. Book early when storms approach—everyone else will have the same idea.
Explore Phang Nga Bay
Phang Nga Bay stands out as one of September’s best activities because its towering limestone cliffs create natural protection from monsoon conditions. While Phuket’s west coast faces rough seas, the bay’s dramatic karst formations act as barriers against strong winds and waves. These sheltered waters remain calm and accessible for boat tours and kayaking when other marine activities are restricted. Hidden lagoons and sea caves between limestone walls offer peaceful exploration opportunities even during rainy weather. September brings additional benefits, including fewer crowds and lower prices.
Events and Festivals in September
Por Tor Festival – Hungry Ghost Festival
The Por Tor (Hungry Ghost) Festival in Phuket is a month-long Hokkien Chinese tradition honouring the dead in August or September when spirits are believed to visit the living world. Families prepare home feasts and make offerings at shrines, especially Por Tor Gong in Phuket Town, known for artwork depicting sins and punishments. The signature offerings are red turtle cakes (ang ku), symbolising luck and longevity, seen notably at Sheng Tek Beo Shrine in Bang Niew. Events span markets and town streets with daily activities.
