Phuket in December 2026: Weather, Prices & Things to Do
In brief: December is peak high season on Phuket. Daytime temperature 31°C, nighttime 23°C, sea water 28°C, only 8 rainy days. The best weather of the year: dry, sunny, the sea is like glass. All excursions are running, all beaches are perfect, snorkeling and diving are at their best. But prices are at their maximum — especially around New Year's. Book 2–3 months in advance.
Weather in Phuket in December
December is one of the best months weather-wise. The northeast monsoon brings dry air, there are almost no waves, and the sky is clear. Rain does occur, but rarely and briefly — 15–20 minutes, after which the sun returns.
| Parameter | Value |
|---|---|
| Daytime temperature | 30–32°C |
| Nighttime temperature | 22–24°C |
| Sea temperature | 28°C |
| Rainy days | 8 |
| Rainfall | ~60 mm |
| Humidity | 70–75% |
| UV index | 10–11 (very high) |
| Season | High (HIGH) — peak |
Evenings in December are pleasant — 23–25°C; you can stroll along the waterfront in a t-shirt without feeling stifled. Humidity at 70–75% is noticeably lower than the summertime 85%, and breathing feels easy. Compared to July, the air seems different — dry, clear, fresh. The UV index remains high (10–11), so sunscreen is essential even for half an hour at the beach.
In over four years on Phuket, I have never once seen prolonged rain in December. At most, a brief fifteen-minute shower, after which the sky clears and a rainbow appears. Perfect weather for any activity, from beach time to trekking. For a month-by-month climate overview, see our complete Phuket weather guide.
What to Wear and Pack
December is the one month when evenings by the sea can actually feel cool. Here is what I recommend:
- Daytime clothing: light shorts, t-shirts, swimwear. Standard tropical gear
- Evening clothing: a light sweater or windbreaker for the evening by the sea (22–24°C + breeze). For New Year's Eve — smart attire (dress code at clubs and restaurants)
- Snorkel mask and tube — it's the high season, visibility up to 25 meters, don't miss out
- SPF 50 sunscreen (UV index 10–11)
- Camera / GoPro — underwater shots will be stunning
- Booking confirmations — print everything or save offline, cell signal in NYE crowds can be unreliable
What's Open
In December, absolutely everything is running:
- Similan Islands — daily excursions, visibility up to 30 m
- Phi Phi, Racha, Coral — consistent, no cancellations
- All beaches — calm sea, green flags

Best Excursions in December
December is the month when absolutely everything is available. Here are the top excursions:
- Similan Islands — the best snorkeling in Thailand, book at least a week ahead
- Phi Phi + Bamboo + Maya Bay — a classic, the sea is perfect
- Sunset yacht cruise — catamarans, sailboats, champagne on board

- Racha Yai full day — snorkeling, beach, lunch on the island
- Khao Sok (2 days) — national park, Cheow Lan Lake, overnight stay on the water
- Phang Nga Bay — James Bond Island, kayaking, caves
Important note: in December, excursions need to be booked in advance. Similans — at least a week ahead, sunset yacht cruises — 3–5 days. In the last ten days of December, popular trips fill up completely. Full catalog on our excursions page.
December Prices — The Year's Maximum
December is the most expensive month, especially the New Year dates (Dec 20 – Jan 10). Here is a comparison with the low season (July):
- 5-star hotels — from 7,000 baht/night (on NYE — from 12,000–25,000 baht). In July the same room costs 2,500 baht
- 4-star hotels — from 3,500 baht/night (on NYE — from 5,000–8,000 baht). In July — from 1,500 baht
- Pool villas — from 6,000 baht/night (in July — from 3,000 baht)
- Flights — significantly higher than off-season fares
- Similan Islands excursion — from 3,500 baht/person
- Scooter rental — 300–400 baht/day (in July — 200 baht)
- NYE dinner at a hotel — 3,000–15,000 baht/person (mandatory at most 5-star properties)
Money-saving tip: December 1–15 is significantly cheaper than December 20–31. If you're not tied to New Year's Eve, fly in early December. The weather is the same, but prices are 30–50% lower. I always advise friends to take this approach — you get the same perfect weather, the same excursions, but without the crowds and premium pricing.
New Year's Eve in Phuket
New Year's Eve on Phuket means warmth, beach, fireworks, and no snow. Here are your options:
- Patong Beach — a free mass party, countdown, fireworks from midnight. Crowded, loud, and great fun
- Bangla Road — a street of bars and clubs, parties until morning, entry from 500 baht with a drink
- Beach clubs (Catch, Xana, Dream) — tickets 5,000–15,000 baht, including dinner, drinks, and a DJ
- Restaurants at Promthep Cape — romantic dinner with a sunset view, then fireworks
- Hotel gala dinner — most 5-star hotels host NYE dinners (mandatory when booking these dates)
- Sunset yacht + New Year's on the water — from 8,000 baht/person, limited spots
My personal advice: if it's your first New Year's Eve on Phuket, head to Patong. Yes, it's crowded, yes, it's loud — but the atmosphere is incredible. Thousands of people from all over the world on the beach, fireworks launched simultaneously by dozens of hotels along the shore — the sky lights up from horizon to horizon. These are memories that last a lifetime. After midnight, you can head over to Bangla Road to continue celebrating in the clubs.
If you prefer something quieter — Nai Harn or Kata. They have fireworks too, but without the crowds. Locals and expats usually gather in groups on the beach, bringing food and drinks. Intimate and cozy.
Booking Ahead — Not a Recommendation, a Necessity
In December on Phuket, advance booking isn't advice — it's an absolute necessity. Here are my recommended timelines:
- Hotel for New Year's (Dec 25 – Jan 5) — book 2–4 months ahead. By early December, good options are already taken
- Flights — 2–3 months ahead. Prices rise exponentially as the date approaches
- Similan Islands excursion — 1–2 weeks ahead. In the last ten days of December — 3 weeks
- NYE restaurant dinner — 2–3 weeks ahead. Top places (e.g., Bampot, Suay) fill up fast
- NYE yacht — 1 month ahead. Few spots, huge demand
- Scooter rental — in peak season good scooters (Honda PCX, Honda Click) get snapped up. Book through trusted rental providers in advance
Personal Experience: December Through a Local's Eyes
I've lived on Phuket since 2020 and every December I watch the same thing unfold: the island comes alive. Starting in November tourists begin arriving, and by December 15 Phuket is fully in high-season mode. Beaches are packed, restaurants require reservations, traffic jams form on the roads.
But December is still my favorite month. The weather is perfect: dry, not too hot, a breeze off the sea. In the morning I head to Nai Harn or Freedom Beach, where the water is clear as glass — visibility 20 meters, fish right at the shore. In the evening — sunset at Promthep or dinner in Old Town, where street cafes set out tables right on the sidewalks.
A special treat is December diving. Visibility at the Similans reaches 30 meters, and at Hin Daeng you can spot manta rays. I've seen them twice in December — giant creatures with wingspans up to 4 meters, gliding through the water like birds. If you're a diver, December on Phuket is a must.
As for New Year's — I've celebrated it on Patong beach, on a yacht, and on a quiet beach with friends. Each option has its own charm. But one thing I can say for sure: New Year's Eve at +28°C, in shorts, on the beach — is an experience that changes your relationship with holidays forever. No snow, no cold, no heavy winter coats. Just warm sand, warm sea, and fireworks above the palm trees.
Tips from a Local Resident
- Book EVERYTHING in advance — hotel, flights, excursions, NYE restaurant. In December nothing is available last minute
- December 1–15 = paradise — same weather, 40% cheaper, 3x fewer people
- Avoid Patong on NYE if you don't like crowds — Nai Harn, Kata, and Bang Tao are significantly quieter
- Rent a scooter in advance — in peak season the good ones get taken. You can also find travel companions for shared trips — December on Phuket has plenty of visitors
- Do the Similans in early December — by month's end the groups are overcrowded
- Traffic jams in December are real — Patong and Chalong get gridlocked, especially during rush hour (5–7 PM). Plan extra time
- King's Cup Regatta (usually early December) — a beautiful sight off Kata, free to watch from the beach
- December sunsets — some of the best of the year. Promthep Cape, After Beach Bar, Karon Viewpoint — don't miss them
