• Average daily lows: 17°C/63°F
• Average precipitation: 14 mm/0.5 in

In December, Chiang Mai enjoys almost 100% guaranteed sunny days. But the temperatures vary between different areas.

With a tropical climate, downtown Chiang Mai remains warm in December (its coolest month), with daily highs averaging 29°C/84°F.

The mountainous areas, on the other hand, would offer a chilly winter atmosphere as the temperature would drop between 5°C (41°F) and 10°C (50°F), particularly on Doi Inthanon. You could see grass and trees covered with frosted ice tips in the early morning.

Is December a Good Time to Visit Chiang Mai?

Definitely! December is part of the dry season (November to April), with cool, comfortable weather.

Outdoor activities are in full swing, and hiking trails that were off-limits during the rainy season (May to October) are back open.

While Christmas vibes might be minimal, Chiang Mai shines with lively New Year celebrations.

However, December is also a peak tourist season. You'd better be prepared for larger crowds and potentially higher costs. It's advisable to book accommodation and activities at least 3 months in advance to secure the best options.

What to Wear in Chiang Mai in December

In December, Chiang Mai experiences significant temperature changes, so layering is key. A light jacket is perfect for cool mornings and nights, while lightweight, breathable clothing works well during the day.

If visiting temples, make sure to cover your shoulders and knees. You should also pack shoes that are easy to slip on and off as it is required to remove them for a temple visit.

If you plan to visit Doi Inthanon, take a thicker jacket, as temperatures at the summit could dip below 10°C (50°F).

Don't forget essentials, such as sunscreen, sunglasses, and a hat, as the sun could still be strong even in the cooler weather.

Top 6 Things to Do in Chiang Mai in December

1. Enjoy an Ethical Encounter with Elephants

Elephants are the big stars for travelers to Chiang Mai. The cool weather in December offers the perfect condition to visit elephant sanctuaries, as most of their programs include outdoor activities that range from observing elephants in less-sheltered campgrounds to walking with them in the jungle.

For better elephant welfare, we strongly recommend the following sanctuaries:

• 100% hands-off sanctuaries: ChangChill and BEES are well-known for no-contact observation.
• Those with ethical interactions (no riding, no chains, no bullhooks, and respectful feeding/bathing): Elephant Nature Park, Elephant Rescue Park, and Kanta Elephant Sanctuary are great for interacting with elephants up close.

With limited daily visitors to sanctuaries, you're advised to book at least 3 months in advance to guarantee a place in the busiest month of December.

2. Indulge in a Typical Lanna-Style Temple

Chiang Mai is full of Lanna temples, especially within the old city. Without scorching heat, strolling inside the temples becomes more pleasant. The promised sunsets/sunrises also add a stunning background to these elegant temples.

For an immersive experience, you could choose a temple walking tour in the Old City, dotted with temples every few steps. Don't miss the liveliest Wat Phra Singh, grandest Wat Chedi Luang, and oldest Wat Chiang Man.

Another highlight should be Wat Phra That Doi Suthep, which is a 40-minute drive from the city. You could enjoy a panoramic vista of Chiang Mai from the temple. A sunset visit also includes a more peaceful vibe along with a monk-chanting ceremony.

3. Take Part in the Century-Old Tradition of Almsgiving

Every morning between 6am and 7am, Chiang Mai comes alive with the peaceful ritual of almsgiving, where devoted locals offer food to the monks. In December, you could engage in this meaningful cultural experience without the distractions of heat or rain.

For the most iconic scene, head to the Kruba Srivichai Monument at the base of Doi Suthep, where monks line up in their saffron robes. You could also join in with or observe the almsgiving at the gates of the Old City or near popular temples throughout the area.

Tip: If you choose to participate, remember to dress modestly and avoid physical contact with the monks.

4. Create Your Own Northern Thai Cuisine

In Chiang Mai, taking a cooking class is a fun and interactive way to spend quality time with your loved ones. The cool weather makes cooking more enjoyable without the heat in December.

Most cooking schools include a market visit, the preparation of 4–6 courses, and tasting them in their classes. Asia Scenic is one of the best places to join in with this activity. Check out its highly-rated farm option, in which you could cook your own dishes in their atmospheric outdoor kitchen!

5. Go Wild with a Hike in Doi Inthanon

For outdoor enthusiasts, your Chiang Mai trip is not complete without a hike on Doi Inthanon, Thailand's highest peak. The clear skies during this period provide excellent visibility to fully appreciate the stunning panoramas of the surrounding mountains and valleys.

If you prefer an easy option, the Ang Ka Nature Trail offers a half-hour boardwalk loop through a lush cloud forest filled with moss and ferns.

For a more challenging adventure, take on the Kew Mae Pan Nature Trail (open from November to May only). This moderate 2–3-hour trek would allow you to escape the crowds while enjoying spectacular panoramic views and diverse scenery from jungles to alpine meadows.

6. Celebrate New Year with Your Loved One(s) the Thai Way

Celebrate the new year in Chiang Mai and immerse yourself in a uniquely exotic experience.

You could see modern festivities with lively decorations and concerts in big shopping malls and special night markets around Tha Phae Gate.

If you're after something uniquely Thai, go with the Chiang Mai CAD New Year Countdown event. Even if you've tried different countdown celebrations before, this one is bound to leave a lasting memory.

Picture yourself among 4,000 joyous revelers, cheering as the clock strikes midnight. Fireworks light up the night sky in a stunning display, but the true highlight? The release of thousands of glowing sky lanterns, creating a magical, otherworldly scene that feels as though it is straight out of a dream.
