December Weather in Phuket
Is December Right for You?
Advantages
- Peak cool season weather with daily highs of 30°C (86°F) and comfortable 24°C (75°F) nights - the most pleasant temperatures all year
- Minimal rainfall at just 35mm (1.4 inches) with only 3 rainy days expected, making it ideal for island hopping and outdoor activities
- Northeast monsoon brings consistent winds perfect for sailing and keeps humidity bearable at 70% - locals call this 'fan season'
- Crystal clear waters with 20-25m (65-82ft) visibility for diving and snorkeling as sediment settles after rainy season ends in November
Considerations
- Peak tourist season means accommodation prices increase 40-60% and popular beaches like Patong can feel overcrowded between 10am-4pm
- Strong winds (15-20 knots) on the west coast can make some boat trips to outer islands choppy, occasionally canceling tours to Similan Islands
- Need to book island tours and restaurant reservations 14+ days ahead as availability fills up quickly during high season
Best Activities in December
Similan Islands Diving and Snorkeling
December marks the official opening of Similan Islands after the monsoon closure. Water visibility reaches peak clarity at 25-30m (82-98ft), and the cooler sea temperatures of 26-28°C (79-82°F) make diving comfortable. The northeast winds create perfect conditions for day trips without the rough seas of other months.
Phang Nga Bay Sea Kayaking
The calm post-monsoon conditions make December ideal for exploring limestone karsts and hidden lagoons. Morning tides are particularly favorable, with low water at 8-9am revealing cave entrances. The cooler temperatures prevent overheating during 4-6 hour excursions through mangrove tunnels.
Phuket Town Cultural Walking Tours
December's comfortable morning temperatures of 24-26°C (75-79°F) make exploring Sino-Portuguese architecture pleasant. This is also when local Chinese-Thai families prepare for Chinese New Year (late January/February), so traditional shops stock special ingredients and decorations you won't see other times.
Sunset Sailing Trips
Northeast monsoon winds of 10-15 knots create perfect sailing conditions without the choppy seas of southwest monsoon season. December sunsets occur at 6:15pm, allowing comfortable afternoon departures. The clear post-monsoon skies produce spectacular sunset colors over the Andaman Sea.
Elephant Sanctuary Visits
Cooler December weather is more comfortable for elephants and visitors during walking tours. Morning visits (8-11am) are particularly pleasant with temperatures around 26-28°C (79-82°F). This is also when elephants are most active before seeking shade during midday heat.
Thai Cooking Classes with Market Tours
December brings seasonal fruits like rambutan and mangosteen to local markets, plus cool morning temperatures make market tours comfortable. Many ingredients used in traditional Thai dishes are at peak freshness after rainy season harvests.
December Events & Festivals
Phuket King's Cup Regatta
Asia's premier sailing regatta attracts international yacht crews to Kata Beach. Even non-sailors enjoy the festive atmosphere with beachside parties, live music, and food stalls. The event showcases traditional long-tail boat races alongside modern sailing competitions.
Loy Krathong Festival
Though the main festival occurs in November, many temples in Phuket hold additional celebrations in early December. Locals float decorated baskets on water while making wishes. Chalong Temple and Saphan Hin Park host the most beautiful ceremonies with traditional music and dance.
