The quietest month of the year, the tail of the monsoon, and the last window before the season turns in October.

Source-market holiday
2027년 9월 18일~10월 10일 · approximate · 호주
Adds demand to the last weeks of the low season, when rate cards have not yet switched over. Combined with the Chinese Golden Week at the start of October it makes the first half of October busier than the second half of September, at the same price.
Source-market holiday
2026년 9월 24일~26일 · 한국
Adds Korean arrivals to the island's quietest quarter without moving hotel medians much: September is the low point of the MOTS occupancy series, so the extra demand is absorbed. Flights from Seoul are the expensive part, not the room.
Festival
2027년 9월 29일~10월 7일 · approximate · 푸켓타운
푸켓타운 hotels sell out for the nine days while the beach areas barely notice; taxi and minibus demand into town triples on procession mornings. Streets on the route close from dawn, firecracker smoke is constant, and almost every kitchen in the Old Town switches to a vegan menu.
Source-market holiday
2027년 6월 15일~9월 5일 · approximate
A visible occupancy bump inside the low half of the index without a matching price rise — the monsoon caps what hotels can charge. Family rooms, connecting rooms and villas with big pools are the inventory that actually gets tight in July and August.
2027년 5월 1일~9월 30일
The low half of the index. Hotel and villa medians sit well below the November-to-April figures, tours discount, and the trade-off is the sea rather than the sky: swimming on the west coast is unreliable, and Phang Nga Bay, 푸켓타운 and the east coast carry the itinerary.
2027년 8월 1일~9월 30일
Phi Phi day trips still run in August and September, at low-season prices, but they skip the one stop most people book them for. Operators do not always say so before you pay — check the itinerary for those two months.
2027년 5월 1일~10월 31일
Explains the low-season discount better than the rain does. It is also the reason island day trips are cancelled at short notice between May and October: book refundable, and treat a calm west-coast beach day as a bonus rather than the plan.
Medians per calendar month over 2015–2025. Open-Meteo (ERA5), 2015–2026.
A median 9월 carries 309 mm of rain over 25 days, of which 6 bring more than 20 mm. Daily highs sit around 28.7 °C and nights around 24.8 °C, with about 248 hours of sunshine in the month and humidity near 86%. The sea off the west coast is 거침: a median 9월 has 12 rough-sea days, and the surface water sits around 29.2 °C.
Mu Ko Similan National Park is closed in 9월 — no day trips, liveaboards or charters run.
A median 9월 brings 966,975 hotel guest arrivals in Phuket with occupancy around 66.8%, which makes it the 11th busiest month of the twelve in the Ministry of Tourism and Sports series. Occupancy at this level is what pushes hotel and villa rate cards to their high-season level, and it is why the island’s best inventory is committed months ahead.
9월 sits in the low half of the year: hotel and villa rate cards are at their low-season level and most things can be booked at short notice.

September is the low point of the Phuket year on almost every measure: fewest visitors, lowest occupancy, cheapest rooms, most rain days. The northern school holidays are over, the Asian ones have not started, and the island belongs to residents and to the small group of visitors who have worked out that a wet Phuket morning is usually a dry one.
Maya Bay is closed for the whole month. The west coast is still under red flags on many days, and the Similan park does not reopen until 15 October, so the sea programme is Phang Nga Bay, Coral and Racha on the calm days, and the east coast otherwise.
Korean Chuseok falls in late September in most years, which brings a short, visible wave of Korean groups into an otherwise empty island — the only demand event of the month.
First-time visitors with one week and a fixed idea of what Phuket looks like in photographs.
Australian September–October school holidays (2027년 9월 18일~10월 10일); Chuseok (Korean harvest holiday) (2026년 9월 24일~26일); Phuket Vegetarian Festival (Nine Emperor Gods) (2027년 9월 29일~10월 7일); Northern-hemisphere summer school holidays (2027년 6월 15일~9월 5일).
A median 9월 has 309 mm of rain over 25 days, daily highs around 28.7 °C and nights around 24.8 °C, from eleven years of reanalysis data. Mu Ko Similan National Park is closed in 9월 — no day trips, liveaboards or charters run.
Often not. A median 9월 has 12 rough-sea days on the west coast, and rip currents rather than waves are what drowns people here. Swim where a lifeguard is on duty, take the flags seriously, and use the sheltered east and south coasts on the bad days.
