Chiang Mai in November 2025: The Ultimate Weather & Packing Guide for Yi Peng & Loy Krathong
November is hands-down the best month to visit Chiang Mai. The rainy season ends, the sky turns crystal blue, and the famous Yi Peng Lantern Festival and Loy Krathong light up the night. But there’s a catch: temperatures swing wildly from 31°C (88°F) during the day to 18°C (64°F) at night, and Doi Inthanon can drop to 7-10°C (45-50°F) before sunrise. This 5000+ word guide covers everything you need to pack and wear to stay comfortable, respectful, and stylish.
Why November is Perfect – But Tricky
- Rainfall drops dramatically: only 41-44 mm all month, ~4 rainy days
- Cloud cover falls from 54% to 38% → perfect blue skies for photos
- Average humidity 74-76% – still tropical, clothes must dry fast
- Day/night temperature difference: 10-12°C in the city, up to 20°C+ in the mountains
Chiang Mai City Temperature Breakdown
- Daytime high: 30-31°C (86-88°F) – feels hot and sunny
- Nighttime low: 18-20°C (64-68°F) – long sleeves or light jacket required
- Best advice: dress in layers you can remove easily
Mountain Microclimate Warning
- Doi Suthep (1000m): daytime ~27°C, early morning ~17°C
- Doi Inthanon (2565m): summit before sunrise regularly hits 7-10°C, sometimes lower If you plan to chase sunrise at Thailand’s highest peak, pack real cold-weather layers (fleece, windbreaker, beanie, gloves).
The Golden Rule: 3-Layer System
- Moisture-wicking base layer (Merino wool or synthetic – NO pure cotton)
- Lightweight insulating mid-layer (fleece jacket or thin down vest)
- Windproof/shell outer layer (especially for mountains and songthaews)
Daytime (30-31°C) – Beat the Heat
- Tops: Uniqlo AIRism, Lululemon Swiftly, Decathlon Merino blend
- Bottoms: Linen pants, quick-dry hiking pants, flowy midi skirts
- Shoes: Teva/Birkenstock sandals (easy on/off for temples)
- Must-have: wide-brim hat, sunglasses, reef-safe sunscreen
Nighttime & Festivals (18-22°C)
- Add a packable puffer vest (Uniqlo ultra-light), thin fleece, or cardigan
- Scarf/shawl: doubles as temple shoulder cover and warmth
- Closed walking shoes if you’ll be on your feet for hours releasing lanterns
Temple Dress Code – Avoid Getting Turned Away
- Shoulders and knees must be covered
- Best combo: lightweight linen pants + long-sleeve breathable shirt + large scarf
- Easy slip-on shoes (you’ll remove them inside every temple)
Yi Peng & Loy Krathong Outfit Ideas
- Women: maxi dress or linen two-piece + denim jacket or shawl (beige/earth tones photograph beautifully under lanterns)
- Men: linen shirt + chinos + light knit sweater
- Rent traditional Lanna clothing for iconic photos (available everywhere during festival week)
Fabric Comparison – What Actually Works
- Pure Cotton: absorbs sweat, stays wet, smells → avoid as base layer
- Linen: breathable, stylish, dries reasonably fast → perfect for city
- Polyester/Nylon quick-dry: fastest drying, great for hiking → ExOfficio, Columbia
- Merino Wool: temperature regulating, odor-resistant for 3+ days → Icebreaker, Smartwool, Decathlon Travel 500 Winner for most travelers: Merino base + synthetic or fleece mid-layer
Where to Buy Gear in Chiang Mai (If You Under-Pack)
- Decathlon (near Tha Pae Gate) – affordable Merino and quick-dry basics
- Central Festival – North Face, Adidas, Columbia outlets
- Local outdoor shops like Thailand Outdoor
Where to Stay in November
- Old City: walkable, historic, budget-friendly
- Nimmanhaemin (Nimman): trendy cafés and bars
- Riverside: quiet luxury, but farther from action Book 2-3 months early – prices triple during lantern festival!
Final Packing Checklist
- 3-4 quick-dry/Merino tops
- 1-2 linen or lightweight pants
- 1 packable down vest or fleece
- 1 windbreaker/rain shell
- Large scarf (temple + warmth)
- Comfortable sandals + walking shoes
- Hat, sunscreen, insect repellent, power bank
November in Chiang Mai is magical – blue skies, cool evenings, and thousands of glowing lanterns. Pack smart, layer wisely, and you’ll have the trip of a lifetime.
