Phuket in December 2026: Weather, Prices & Things to Do

Phuket in December — sunset at Surin Beach and New Year lights

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.

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:

December is the month when absolutely everything is available. Here are the top excursions:

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):

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:

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:

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.
