Phuket Weather in December 2026: Peak Season Guide – Prices, Activities & What to Expect

Temperature in December

Daytime temperatures average 31°C (88°F), with nights cooling to a comfortable 24°C (75°F). Humidity drops, making it feel pleasant even at midday. A sea breeze on west coast beaches like Patong, Kata, and Karon adds to the comfort. Pack light clothing – cotton, linen, swimwear – plus a light jacket or wrap for air-conditioned spots and evening strolls.

Does It Rain in December?

December is one of Phuket's driest months. Average rainfall is around 50 mm (2 inches), spread over just 5 to 8 rainy days. Expect sunny days from morning to evening. Rain is usually a short, passing shower that clears quickly. Cloud cover is minimal, so plenty of sunshine for beach days, island hopping, and outdoor activities.

Sea Conditions in December

The Andaman Sea is calm and inviting in December. Waves are small, underwater visibility is good, and the water temperature stays around 28°C (82°F). Perfect for swimming, snorkeling, diving, and boat tours to Phi Phi, James Bond Island, and the Similan Islands (open Oct–May). Jellyfish are rare, but always check local warnings.

December and Rental Prices

December is the most expensive month for accommodation in Phuket. Hotels, villas, and long-term rentals can be 50–100% higher than in low season (May–October). For stays of a month or more, book 2–3 months ahead to lock in a reasonable rate. Studios that cost $400–500/month in low season may jump to $700–900. Many travelers find the premium worth it for guaranteed great weather.

Is December a Good Time to Visit Phuket?

Yes, if perfect weather tops your list and crowds don't bother you. You'll get reliable sunshine, calm seas, and a festive atmosphere – especially during Christmas and New Year with events, fireworks, and beach parties. On a tight budget or prefer quieter surroundings? Try November (transition month) or January after the New Year rush. For first-timers and anyone seeking a classic tropical holiday, December is fantastic.

Activities and Events in December

  • Beach time: Less crowded beaches like Kata Noi, Freedom Beach, and Laem Singh (still busy).
  • Island tours: Calm seas make day trips to Phi Phi, Coral, and Racha Islands ideal.
  • New Year's Eve celebrations: Fireworks at Patong Beach, rooftop parties, and countdown events across the island.
  • Water sports: Paddleboarding, kayaking, and jet skiing thrive in flat seas.

What to Pack for Phuket in December

  • Lightweight clothing (shorts, t-shirts, sundresses)
  • Swimwear and a rash guard for sun protection
  • High-SPF sunscreen, sunglasses, and a wide-brimmed hat
  • A light jacket or pashmina for evenings and air-conditioned venues
  • Comfortable sandals or flip-flops
  • Reusable water bottle to stay hydrated
  • Insect repellent (especially for evening outings)

Final Verdict

December is Phuket at its most photogenic: excellent weather, calm sea, and infectious holiday spirit. Trade-offs are higher prices and larger crowds. Plan ahead and budget accordingly to experience the island at its prime. For long-term renters and digital nomads, it's vibrant but expensive. Weigh weather vs. cost and decide.
