What to Wear in Chiang Mai in December

Chiang Mai, located in northern Thailand, experiences a cooler and drier season in December compared to the rest of the year. This cooler season is part of what makes Chiang Mai a top destination during the winter months, attracting tourists seeking both adventure and relaxation. To fully enjoy your trip, you need to be prepared for the specific weather conditions you will encounter in December.

Chiang Mai's December Weather: What to Expect?

In December, Chiang Mai experiences its coolest weather, but don’t let the word “cool” confuse you—this is still Thailand. During the day, temperatures typically range from 24°C to 29°C (75°F to 84°F), while at night and early mornings, it can drop to around 10°C to 15°C (50°F to 59°F). This temperature difference means that while you can comfortably wear shorts and T-shirts during the day, you’ll need something warmer for evenings.

The cooler mornings and evenings make outdoor activities, such as trekking to Doi Inthanon or visiting the Elephant Nature Park, particularly enjoyable, but it also means you should layer your clothing to adjust to the changes in temperature throughout the day.

What to Wear During the Day in Chiang Mai?

For daytime activities, lightweight, breathable clothing is ideal due to the midday warmth. A few key items that should make it into your suitcase include:

• Cotton T-Shirts or Tank Tops: Chiang Mai can get warm during the day, and breathable fabrics like cotton or linen will help keep you cool.
• Shorts or Lightweight Trousers: Lightweight, airy trousers or shorts are ideal for staying comfortable during day trips, whether you're exploring the city or heading into the countryside.
• Comfortable Walking Shoes: You’ll likely be walking a lot in Chiang Mai, from temple hopping to navigating the city’s famous markets. Opt for comfortable sneakers, hiking sandals, or lightweight trainers.
• Sunglasses and a Hat: The sun is still quite strong during the day, so protect yourself from UV rays with a hat and a good pair of sunglasses.

While the sun is shining, you’ll feel comfortable in casual summer clothes, especially if you're taking part in outdoor adventures like visiting temples or exploring the Old City. However, don’t underestimate the cooler parts of the day.

Dressing for Evening and Nighttime:

Chiang Mai gets significantly cooler in the evening and early morning during December. Temperatures can drop to around 10°C (50°F), and if you’re not prepared, you might find yourself shivering at a night market or outdoor restaurant. Here’s what to pack for cooler nights:

• Light Sweaters or Cardigans: These are perfect for layering over your daytime clothes when the temperature drops. You can take it off if you get warm but will appreciate it when the cool air hits.
• Long-Sleeved Shirts: Opt for long sleeves to keep warm but still maintain breathability in case you get a little warm while walking around.
• Jacket or Hoodie: A slightly thicker jacket, like a fleece hoodie or a lightweight windbreaker, can make a huge difference in comfort levels when temperatures drop to their lowest at night.

If you’re visiting higher altitude places like Doi Suthep or Doi Inthanon, it’s worth noting that the temperature can drop further, sometimes to as low as 5°C (41°F), so be prepared with warmer layers.

What to Wear When Visiting Temples?

When visiting the beautiful temples of Chiang Mai, such as Wat Phra Singh or Wat Chedi Luang, it’s important to dress modestly out of respect for the culture and religion. You’ll need to cover your shoulders and knees. Here are some options to consider:

• Long Skirts or Trousers: These are comfortable and ideal for temple visits. Women should opt for skirts that cover the knees, while men can choose lightweight trousers.
• Scarves or Shawls: Carry a scarf or shawl to cover your shoulders when entering temples. It’s an easy way to adhere to the dress code without feeling too hot outside.
• Slip-On Shoes: Since you’ll need to remove your shoes before entering temples, shoes that are easy to take on and off, such as sandals or slip-on sneakers, are a good choice.

Dressing for Outdoor Adventures:

December is a great time for trekking in the mountains surrounding Chiang Mai, visiting national parks, or engaging in activities like zip-lining and mountain biking. For these outdoor adventures, you’ll want to dress in layers and bring practical gear:

• Moisture-Wicking T-Shirts: If you’re planning on hiking or engaging in other physical activities, moisture-wicking athletic wear will help keep you comfortable by drawing sweat away from your body.
• Hiking Pants or Leggings: Lightweight, durable pants or leggings are ideal for trekking. Make sure they’re breathable but also provide enough warmth in the cooler mornings.
• Hiking Boots or Trail Shoes: Good-quality hiking boots or trail shoes are a must if you’re planning on doing any serious trekking.
• Backpack with a Water Bottle: Bring a small daypack to carry water, sunscreen, and an extra layer for when the temperature drops.
