A domestic long weekend on top of an already busy international week. Government counters close; the airport, the 찰롱 road and the 빠통 tunnel run at their December worst. Rates are already at high-season level and do not move for the holiday itself.
No effect on rates or crowds beyond a possible Thai long weekend. Practical only: close visa, licence and banking business before it, because December counters get busier every week afterwards.
Maximum prices and maximum crowds. Compulsory gala dinners are added to the room rate at most beach hotels for 31 December; transfer and taxi prices roughly double on the night; a booked car with a driver is worth more than usual.
Stretches the peak fortnight to 8 January instead of 2 January. Long-stay villa inventory in 방따오, 라얀 and 라와이 is committed by the previous spring; the January arrivals wave is what keeps January rates level with December's.
Steady short-stay demand through the ramp into the peak fortnight, concentrated on weekends. It is one of the reasons December rates rise before the European and Russian holiday traffic actually arrives.
까따 and 까론 beachfront hotels run near capacity for the regatta week and the marinas at Ao Po and Boat Lagoon fill with visiting boats. Everywhere else on the island the effect is invisible; the rate pressure comes from the season, not the racing.
The clearest price signal in the index. Everything is at its annual maximum — hotels, villas, transfers, boat charters, restaurants with set menus. Booked six to twelve months ahead for villas, three to six for hotels; late cancellations rarely reprice downwards.
The reason the price index has two levels: hotel and villa rates through these five months sit well above the May-to-October ones, and the Christmas fortnight sits above the rest of the dry season again. Book villas for December and January six to nine months ahead.
The single hardest constraint on a Phuket itinerary: a trip planned between 16 May and 14 October cannot include the Similans at all. Inside the window, December to February sells out first and April is the quietest month with good sea.

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.

December is Phuket at full volume. The weather is as good as it gets — flat sea, low rain, clear evenings — and the island is priced accordingly. The month divides sharply: the first two weeks are ordinary high season, busy but bookable, and from roughly the twentieth the peak fortnight takes over and every rate on the island reaches its annual maximum.
The peak is not driven by one market. Russian, European, Indian, Kazakh, Malaysian and Australian holiday calendars overlap in the same fortnight, which is why nothing releases: a cancellation is absorbed the same day. Minimum stays of seven to ten nights appear on villas, and compulsory gala dinners are added to the room rate on the twenty-fourth and the thirty-first.
Three Thai holidays fall in the month — the fifth, the tenth and the thirty-first — and the King's Cup Regatta finishes in the first week off 까따. If you need immigration, a bank or the land office, do it before the tenth.
